Abstract

The invention relates to a glass fiber impregnating compound for a chopped strand mat. The impregnating compound is prepared from, by mass, 0.5-3% of silane coupling agent, 3-15% of polyester emulsion, 1-5% of polyvinyl acetate emulsion, 1-6% of lubricant, 0.2-2% of antistatic agent, surfactant, 0.06-2% of pH regulator and the balance deionized water; the pH value of the impregnating compound ranges from 2 to 10. The glass fiber impregnating compound enables glass fibers to have good bundling performance, cutting performance and dispersibility, the finished product is good in softness, compatibility with resin is good, impregnating is fast, and the product has good mechanical properties.

Description

Technical field [0001] The invention belongs to the field of glass fiber sizing agents, and particularly relates to a glass fiber sizing agent for chopped strand mats. Background technique [0002] Glass fiber chopped strand mat is a medium-alkali or non-alkali made of continuous glass fiber strands chopped into 50mm length, uniformly distributed without orientation, and mixed with a binder (or emulsion binder). Glass fiber non-woven felt products. Glass fiber is an inorganic non-metallic material, and it is an indispensable and important raw material in various fields such as petrochemical, electronic power, road transportation, aerospace and so on. Production started in foreign countries in the early 1970s and has now developed into one of the main products of glass fiber. Since the late 1970s and early 1980s, my country began to develop its own production equipment and technology for chopped mat. Through continuous technological innovation and technology introduction, my co...
