一种高光泽高流动性pa6的制备方法

Preparation method of high-luster and high-fluidity PA6 (polyamide6)

Abstract

The invention provides a preparation method of high-luster and high-fluidity PA6 (polyamide6). The high-luster and high-fluidity PA6 is prepared by polymeric modification according to the following molar ratio: 100 of caprolactam, 1.0-5.0 of polyhydroxy triazine compounds or aliphatic polyols converted into the amount of substance of hydroxyl, 5.0-20 of water, and 0.01-0.08 of lubricant. The preparation method has the characteristics of low cost of raw materials, simple process, good product color and luster without yellowing, and significantly improved melt fluidity.
本发明提供了一种高光泽高流动性PA6的制备方法,按“己内酰胺100、多羟基三嗪类化合物或脂肪族多元醇换算为羟基的物质量1.0~5.0、水5.0~20、润滑剂0.01~0.08”摩尔比进行聚合改性,得到高光泽高流动性PA6;该方法具有原材料成本低、工艺简单、产品色泽好、不发黄,熔体流动性得到显著的特点。
