铝银浆 只是涂料和油漆的原料之一。在制作油漆之前，需要添加溶剂/树脂/分散剂等！ 一、溶剂：如醋酸丁酯、丙二醇甲醚等。其作用是溶解树脂等成膜物质，调节涂料的粘度和干燥速度。二、树脂：常见的有丙烯酸树脂、聚酯树脂等。树脂是涂料的成膜物质，决定了涂料的基本性能，如附着力、硬度、耐候性等。三、分散剂：可减少铝银浆分散过程所需的时间和能源，稳定铝银浆预分散，调整其表面性质和流动性，防止铝银浆颗粒团聚。四、银粉取向剂：可以保证车漆的光泽度，使车漆呈现出更好的金属质感。五、流平剂：有机硅流平剂或丙烯酸流平剂可以使油漆在干燥过程中形成平整光滑的表面Ⅵ、防沉剂：如聚酰胺蜡、聚乙烯蜡等，可防止铝银浆在涂料中沉降，保持涂料体系的稳定性Ⅶ、其他添加剂：可根据需要添加增稠剂来调节油漆的粘度，可添加防锈剂、防腐剂来提高油漆的防腐性能。

使用前，预分散 铝银浆 与溶剂。一般来说，铝浆与溶剂的比例 比例为1:2。分散过程中，使用低速搅拌。避免搅拌速度过快，导致高剪切 力会破坏铝浆的形状，降低亮度。最佳分散速度应为 通过实验确定。这取决于许多因素以及搅拌器的几何尺寸 设备（搅拌盘直径与容器直径的比例、搅拌盘的形状、 等）、涂料的温度和粘度、溶剂的选择以及铝浆的添加量（见 （见下表）

亮度、亮度、色彩饱和度、覆盖率、随角异色性和 DOl - 不仅取决于颗粒和颗粒大小 分布，也取决于方向 铝片 在 漆膜。 最佳效果如下： 薄片与薄膜表面平行。较差 方向：导致“浑浊”或不均匀的“盐和 胡椒”效应。 溶剂的蒸发导致薄膜收缩，实际上挤压 铝银浆 处于水平位置。 油漆的溶剂含量越高， 这种效应很明显。这解释了观察到的 颜料取向现象 因此“低固体涂料”的光学性能相当 比高 固体油漆”。

所用金属的延展性意味着铣削或粉碎 球形铝粉 在球里 磨机产生的薄片形状因子（薄片厚度：薄片直径）为 1:50 至 1:200。 银元形状：采用粒径极窄的细颗粒球形铝粉，经过缓慢 研磨工艺，可得到表面光滑、径厚比适中、颗粒较窄的铝板 尺寸分布均匀，光泽度高，遮盖力强。 雪花状、鳞片状：采用粒度较粗的铝粉研磨而成。 统计颗粒厚度可能因产品和所用的研磨技术而异，即各种 颜料不是单分散颗粒，而是具有或多或少 颗粒尺寸和厚度的统计分布。 粒度分布 金属颜料 对应用的光学特性具有决定性的影响。 因此，测量粒度分布对于质量控制和对颜料进行分类至关重要， 薄片的各向异性使得这一过程变得困难

在生产过程的各个阶段都必须添加润滑剂，以防止结块，这具有 对润湿性能的独特影响 金属颜料. 润湿性能有明显差异 介于叶型和非叶型之间。 浮型颜料 由于其高表面张力 浮色颜料 不被粘合剂润湿，因此漂浮在 湿膜。这种效果是通过使用例如硬脂酸作为润滑剂来实现的。 在含有强极性溶剂或粘合剂的涂料体系中，漂浮颜料总是存在危险 通过润湿“淹没”并变成 非浮型颜料。必须考虑到这种可能性 在制定涂料配方时，如有必要，应使用特殊的漂浮稳定颜料。 非浮型颜料 非浮型颜料是通过添加强极性物质或润湿剂来产生的 漂浮颜料或在研磨过程中直接使用特殊润滑剂（例如油酸）。 非漂浮颜料完全润湿，从而均匀分布在整个漆膜上。

  Have you ever stared at a sleek car finish, a glamorous lipstick, or a sparkling gift box and wondered what gives them that enchanting, light-shifting glow? That magic is likely thanks to pearlescent pigment—a versatile and extraordinary material that’s quietly transforming everyday objects into something extraordinary. At its core, pearlescent pigment (often mistaken for pearl powder) is a fine powder crafted from materials like mica coated with titanium dioxide or other oxides. Its unique structure bends and reflects light in a way that mimics the soft, iridescent luster of natural pearls. Unlike harsh metallic pigments, it creates a gentle, shifting glow that deepens with every angle, adding a touch of luxury and elegance.   In cosmetics, pearlescent pigment is a staple. It turns ordinary eyeshadow into a multidimensional palette, gives lipsticks a creamy, luminous sheen, and makes nail polish shimmer like polished gemstones. Foundations and highlighters infused with it blur imperfections, leaving skin with a natural, dewy radiance that feels both healthy and high-end.   In design and manufacturing, its impact is far-reaching. Automotive paints use it for stunning, color-shifting car finishes that stand out on the road. Home decor items—from wall paint to decorative vases—incorporate it to add subtle depth and warmth to living spaces. Even plastic products, like children’s toys and kitchenware, get a playful, sparkling upgrade with pearlescent pigments.   Packaging and textiles also benefit greatly. Luxury gift boxes, cosmetic cases, and shopping bags coated with the pigment feel premium and thoughtful. In fashion, it adds subtle sparkle to clothing, scarves, and accessories, elevating casual wear into something eye-catching without being over the top.   From makeup bags to car doors, pearlescent pigment is the unsung hero turning the ordinary into the extraordinary. Its ability to transform light into beauty makes it an essential ingredient in products we use and admire every day.   In addition, pearl powder is also widely used in packaging and textiles. The shiny gift boxes, high-end shopping bags and even some fashionable clothes all use pearl powder to enhance the sense of grade. It is not as sharp as metal luster, but it can quietly add a touch of elegance and dreaminess to our lives.

  Have you ever been attracted by the metallic texture of a mobile phone case, or noticed the bright silver luster of a car wheel hub? In fact, the secret behind these high-end silver shine effects is aluminum paste — it contains no silver at all. Made with ultra-fine flake aluminum powder as the core, combined with solvents and additives, it creates most of the metallic textures in our lives through the reflection of aluminum flakes.   Aluminum paste has long penetrated daily life: in 3C electronics, the delicate silver-gray color of mobile phone back covers and computer casings is mostly due to fine white aluminum paste, which not only enhances the texture but also slightly protects the internal components. In home appliances, the brushed silver panels of refrigerators and the metal button borders of microwave ovens get rid of monotony and become more exquisite because of it.   It also appears in the eye-catching packaging in supermarkets. The silver foil patterns on cigarette packs and cosmetic gift boxes, as well as the metal labels on snack packaging, are printed with fine-particle aluminum paste, resulting in delicate and shiny patterns that also provide moisture and light resistance. When traveling, the shimmer of metallic car bodies comes from flash silver aluminum paste, while the high-gloss mirror effect of wheel hubs relies on imitation electroplating aluminum paste.   This inconspicuous "silver shine magician" quietly brightens our lives with its texture, allowing ordinary items to have a high-end feel.

  Water-Based vs Oil-Based Aluminum Paste: Pros, Cons & Applications Aluminum paste is a widely used metallic pigment that brings a sleek silver luster to various products. It is mainly divided into two types according to its solvent system: water-based aluminum paste and oil-based aluminum paste. Each has unique characteristics, advantages and disadvantages, and is suitable for different application scenarios. Understanding their differences is key to choosing the right one for your needs. 1. Oil-Based Aluminum Paste As a traditional and mature type of aluminum paste, oil-based aluminum paste uses organic solvents as the dispersion medium. It has long been favored in many fields due to its excellent metallic performance. Pros • Superior brightness: Thanks to the characteristics of its solvent system and resin formula, it has high metal reflectivity, concentrated reflection, strong mirror effect, and the aluminum particles have high parallel arrangement, which can present a bright and high-end metallic luster. • Good adaptability: It has excellent compatibility with solvent-based coatings, inks and resins, and strong adhesion to substrates such as metals and plastics, making it not easy to peel off after construction. • Stable storage under proper conditions: High-quality oil-based aluminum paste can be stored at room temperature for 12-18 months, and its performance remains stable when not exposed to high temperature or direct sunlight for a long time. Cons • High environmental impact: It contains a large number of organic solvents, resulting in high VOC emissions, which is not environmentally friendly and may have a certain impact on the environment and human health. It is also subject to more restrictions under increasingly strict environmental regulations. • Poor dispersion stability: Its dispersion stability is greatly affected by the type of solvent and resin system. It needs high-shear stirring before construction to ensure uniform distribution of aluminum particles, otherwise aluminum flake sedimentation and viscosity changes may occur. • Safety risks: Organic solvents are flammable and volatile, which may bring potential safety hazards during production, transportation and construction. Applications It is mainly used in scenarios with high requirements for metallic luster and less environmental constraints, such as high-end automotive exterior parts, wheel hubs and bumpers, high-end decorative industrial coatings, household appliance panels with strict metallic texture requirements, and some solvent-based inks and plastic coatings. 2. Water-Based Aluminum Paste With the tightening of global environmental protection policies, water-based aluminum paste, which takes water as the main dispersion medium, has gradually become the mainstream choice for green coating. It has been continuously upgraded in technology and can now meet the needs of most application scenarios. Pros • Environmentally friendly: It greatly reduces the use of organic solvents, with low VOC emissions, which is in line with the development trend of green and low-carbon. It has a low odor during production and construction, and is more friendly to the environment and construction personnel. • Excellent dispersion stability: Through special surface modification treatment, it has good wettability and chemical stability in water, with excellent anti-settling performance. It can restore uniformity with low-shear stirring, and its performance remains stable in both high and low temperature environments. • Wide applicability: It has good compatibility with water-based coatings and inks, and is suitable for a variety of substrates, including metals, plastics, paper and wood. It is also easy to construct and suitable for large-area coating operations. Cons • Slightly inferior brightness: In the early stage, its brightness was slightly lower than that of oil-based aluminum paste. Although modern technology has made it close to oil-based products, it still has a slight disadvantage in scenarios requiring extreme mirror reflection effects. • Strict storage requirements: Although it has good environmental adaptability, it is still necessary to avoid moisture and high temperature during storage to prevent aluminum flakes from oxidizing and affecting performance. • Higher cost: The production process of water-based aluminum paste is more complex, requiring surface coating and passivation treatment, so its cost is generally higher than that of oil-based aluminum paste. Applications It is widely used in scenarios with strict environmental protection requirements, such as the coating of public facilities, the appearance parts of household appliances, the shells of 3C products, indoor decorative coatings, water-based inks, and large-area metal effect construction. It is also an important material for the green upgrading of the coating industry. Summary Oil-based aluminum paste is the first choice for pursuing high-brightness metallic luster, while water-based aluminum paste is more suitable for green, environmentally friendly and large-scale construction needs. With the continuous advancement of technology, the performance gap between the two is gradually narrowing, providing more flexible choices for different application scenarios.
