Abstract

The present invention provides a glass fiber wetting agent, which comprises a coupling agent, a lubricant, a film forming agent A, a film forming agent B, an antifoaming agent, an antioxidant, a pH value adjusting agent and deionized water, wherein the solid of the wetting agent accounts for 2-6% of the total mass of the wetting agent. According to the present invention, the wetting agent with characteristics of excellent glass fiber dispersibility, less hairiness and good compatibility effect is prepared by compounding different types of the film forming agents and matching with the suitablecoupling agent, the suitable lubricant, the suitable antifoaming agent, the suitable antioxidant and the suitable pH value adjusting agent. The invention further provides a preparation method of the glass fiber wetting agent, and uses of the glass fiber wetting agent in the CFRT process of glass fiber reinforced polypropylene resins.

Description

technical field [0001] The invention relates to the field of sizing agents, in particular to a glass fiber sizing agent and its preparation method and application. Background technique [0002] CFRT is the abbreviation of Continue Fiber Reinforced Thermoplastic, which is translated into Chinese as continuous fiber reinforced thermoplastic. Over the past half century, advanced structural materials for aerospace and other high-tech applications have been dominated by high-performance thermoset composites until the early 1970s when continuous fiber-reinforced thermoplastic composites emerged as a new advanced material Began to be used in the above fields. In recent years, continuous fiber reinforced thermoplastics (CFRT) have attracted more and more attention from all over the world, and their research and application are very active. Its application fields are mainly concentrated in aerospace, aviation, automobile, building materials, chemical industry, electronics / electrica...
