CN107216778A 一种高仿电镀邦定银粉末涂料及其制备方法 无效 - 驳回

一种高仿电镀邦定银粉末涂料及其制备方法
摘要：
本发明公开了一种高仿电镀邦定银粉末涂料，其原料按重量份数包括以下组分：端羧基聚酯树脂80～90份；异氰酸酯三缩水甘油酯6～8份；有机硅树脂10～15份；萜烯树脂5～10份；聚丙烯酸酯1～3份；苯偶姻0.3～0.7份；荧光增白剂0.5～1份，邦定助剂1～2份，包覆型铝粉0.6～1份。本发明还提供了一种高仿电镀邦定银粉末涂料的制备方法，通过称量配料、预混合、熔融挤出、研磨、邦定、筛分和成品包装得到一种高仿电镀邦定银粉末涂料。本发明一种高仿电镀邦定银粉末涂料及其制备方法，通过调整配方的熔融粘度、清晰度、表面张力、玻璃化温度、邦定温度、邦定时间、邦定速度、粉体流动性来达到电镀表面效果的高光洁度、高清晰度、高亮度、高流平性。
摘要（英）：

The invention discloses high-imitation electroplating bonding silver powder paint which comprises the following components in parts by weight: 80-90 parts of terminal carboxyl group polyester resin, 6-8 parts of isocyanate triglycidyl ester, 10-15 parts of organic silicon resin, 5-10 pars of terpene resin, 1-3 parts of polyacrylate, 0.3-0.7 part of benzoin, 0.5-1 part of a fluorescent whitening agent, 1-2 parts of a bonding aid and 0.6-1 part of coating type aluminum powder. The invention further provides a preparation method of the high-imitation electroplating bonding silver powder paint. The preparation method comprises the following steps: weighing and blending materials, premixing the materials, performing melting extrusion, grinding, bonding, screening, and packaging a finished product, thereby obtaining the high-imitation electroplating bonding silver powder paint. By adopting the high-imitation electroplating bonding silver powder paint and the preparation method thereof, effects of high smoothness, high clarity, high brightness and high leveling properties of an electroplated surface are achieved by adjusting the melting viscosity, clarity, surface tension, glass transition temperature, bonding temperature, bonding time, bonding speed and powder flowability of a formula.
