Black matt impregnated rubber and preparation method thereof

一种黑色亚光浸胶及其制备方法

Abstract

一种黑色亚光浸胶及其制备方法,它涉及一种浸胶及其制备方法。本发明解决了目前刹车片底胶高温稳定性差、保存时间短、使用工艺性差、色泽不能满足黑色亚光及组分容易分层的问题。本发明由单独包装的甲、乙组分组成;甲组分由钼改性热固性酚醛树脂溶液、热塑性酚醛树脂、丁腈橡胶、聚乙烯醇缩醛、着色剂、消光剂、硫磺和有机溶剂组成,乙组分由固化剂和有机溶剂组成;本发明的方法:一、将丁腈橡胶、聚乙烯醇缩醛分别溶解在有机溶剂中,再将其与钼改性热固性酚醛树脂溶液、热塑性酚醛树脂、着色剂和消光剂混合均匀制得甲组分;二、将固化剂溶解在有机溶剂中制成乙组分。本发明的黑色亚光浸胶高温稳定性好、保存时间长、使用工艺性好且组分均匀。
The invention discloses a black matt impregnated rubber and a preparation method. The invention solves the problems that the current brake sheet primer has poor high temperature stability, short preservation time and poor manufacturability, the color can not meet black matt, and the ingredients are easy to be layered. The black matt impregnated rubber is composed of single packaged ingredients of A and B; the A ingredient consists of a molybdenum modified thermosetting phenolic resin solution, thermoplastic phenolic resin, butadiene-acrylonitrile rubber, polyvinyl acetal, coloring agent, delustering agent, sulphur and organic solvent; the B ingredient consists of a curing agent and organic solvent. The method of the invention comprises the following steps: 1, the butadiene-acrylonitrile rubber and the polyvinyl acetal are respectively dissolved in the organic solvent, then the mixture is evenly mixed with the molybdenum modified thermosetting phenolic resin solution, the thermoplastic phenolic resin, the coloring agent and the delustering agent to prepare the ingredient A; 2, the curing agent is dissolved in the organic solvent to obtain the ingredient B. The black matt impregnated rubber has good high-temperature stability, long preservation time, good manufacturability and even ingredients.
