改性纳米沉淀硫酸钡对不同涂料色漆性能的影响

摘要：

  改性纳米沉淀硫酸钡因其优异性能，被广泛用于涂料、油墨、色漆、塑料、造纸、橡胶等诸多工业领域，早已成为业界不可或缺的高档功能性填料。本报告侧重介绍了改性纳米沉淀硫酸钡应用于丙烯酸体系的颜料色漆涂料中，分别论述了添加两种不同硫酸钡在不同颜色的色漆中，对光泽度、透明度、显色性、耐候性、防沉性、反射率等相关性能的影响。结果可见，添加改性纳米沉淀硫酸钡可促进颜料的分散性，降低凝聚性，提高了各项实际应用性能，进而得到了鲜明光亮的涂膜效果，更好地保持及展现了颜料的原有色调，同时能使产品在技术和价格上更具竞争优势。

Abstract：

  Modified nano precipitated barium sulfate is widely used in many industrial fields such as coatings, inks, color paint, plastics, paper making, rubber and so on because of its excellent performance, and has already become an indispensable high-grade functional filler in the industry.

This report focuses on the application of modified nano precipitated barium sulfate in pigment paint of acrylic acid system, and discusses the effects of adding two different barium sulfate in different color paints on the related properties such as gloss, transparency, color rendering, weather resistance, anti-settling and reflectivity. The results show that the addition of modified nano precipitated barium sulfate can promote the dispersion of pigment, reduce the cohesion, improve the practical application performance, and then get a bright film coating effect, better maintain and show the original color of pigment, and at the same time make the product more com....
