PVC色素的生产与应用

PRODUCTION AND USE OF PVC PIGMENT

介绍了一种生产PVC色素的简单方法。用PVC作为颜料的载体树脂,适当添加某些助剂,于特定的加工条件下经过高速热混、低速冷混而成。生产的色素经过PVC挤出板材生产应用,效果良好,其用量为0.56％～1.00％的实际效果与某厂家色母料用量为1.3％～3.7％的相当。

A simple method to produce PVC pigment was introduced. The PVC pigment was prepared by using PVC as the carrier resin of the dye staff, adding some proper auxilary agents and mixing them both at high temperature and at high speed , then mixing them at low ones. The amount of pigment used to produce PVC extrusion plate is 0.56%-1. 00% . Its actual effect is the same as that of other masterbatch whose addtional amonnt is
