Glass fiber impregnating agent as well as preparation method and application of glass fiber impregnating agent

Abstract

The invention discloses a glass fiber impregnating agent as well as a preparation method and application of the glass fiber impregnating agent. The glass fiber impregnating agent contains a solid component and water; the mass of the solid component accounts for 3-8% of the total mass of the impregnating agent; the solid component contains the following components, and the proportion of the mass ofeach component in the total mass of the solid component is as follows: 3-10% of silane coupling agent, 1-10% of lubricant, 20-70% of film forming agent A, 20-70% of film forming agent B and 80-96% offilm forming agent A and film forming agent B, wherein the silane coupling agent contains an amino group, and the film forming agent A and the film forming agent B are polyurethane with different relative molecular weights. A glass fiber product produced by adopting the impregnating agent is capable of meeting the requirement for few filoplumes under high tension of a polyurethane winding process, good in compatibility with polyurethane matrix resin and high in impregnation speed, and the subsequently prepared product is high in mechanical properties.

Description

technical field [0001] The invention belongs to the field of glass fiber sizing agents, and in particular relates to a glass fiber sizing agent for strengthening polyurethane resin winding process, its preparation method and application, and involves a glass fiber thermosetting resin technology. Background technique [0002] Polyurethane composite material has the characteristics of light weight, high strength, good toughness, corrosion resistance, excellent electrical insulation, designable performance, and maintenance-free. It is an ideal choice for pole structural materials. It has begun and is increasingly receiving high attention from domestic and foreign power industries. . Compared with traditional poles (cement poles and steel pipe towers), polyurethane composite poles have the characteristics of light weight, high strength, aging resistance, and excellent toughness. Therefore, in foreign countries, the application of polyurethane poles has already reached a conside...

AI Technical Summary

Problems solved by technology

Since the winding process of polyurethane is more complicated than that of polyester and epoxy resin, its use tension is high, and it is also very sensitive to ambient temperature and humidity. In the process, glass fibers are also required to have less hairiness and low water content. , small migration of combustible content, fast soaking speed, etc., but the glass fiber in the existing market has been difficult to meet its requirements
