一种用于水溶性酚醛树脂的浸渍胶膜纸着色的水性无机颜料色浆及其制备方法
摘要：
本发明公开了一种用于水溶性酚醛树脂的浸渍胶膜纸着色的水性无机颜料色浆及其制备方法，由30.0％-60.0％无机颜料、5.0％-10.0％助溶剂、2.0％-10.0％润湿分散剂、0.2％-5.0％防沉剂、0.2％-0.5％消泡剂、0.1％-0.5％pH调节剂和20％-38％去离子水组成，本发明制备的水性无机颜料色浆与水溶性酚醛树脂相容性良好，着色强度高，从根本上解决了浸染的浸渍胶膜纸着色不均匀，透底等情况，且生产成本低，生产工艺简单，易于工业化生产。
摘要（英）：

The invention discloses an aqueous inorganic pigment slurry for coloring impregnated film adhesive made of water soluble phenolic resin and a preparation method thereof. The pigment slurry is composed of the following components in percentage by weight: 30.0 to 60.0% of inorganic pigment, 5.0 to 10.0% of cosolvent, 2.0 to 10.0% of wetting dispersant, 0.2 to 5.0% of anti-settling agent, 0.2 to 0.5% of antifoaming agent, 0.1 to 0.5% of pH adjuster, and 20 to 38% of deionized water. The compatibility between the prepared aqueous inorganic pigment slurry and water soluble phenolic resin is good, the coloring strength is high; the problems of uneven coloring on impregnated film adhesive and pigment penetration are solved radically, moreover, the production cost is low, the production technology is simple, and the preparation method can be applied to industrial production easily.
