Fast curing epoxy resin system for glass fiber pultrusion frame and preparation method of fast curing epoxy resin system

Abstract

The invention discloses a fast curing epoxy resin system for a glass fiber pultrusion frame and a preparation method of the fast curing epoxy resin system, and belongs to the field of glass fiber processing. The invention relates to a fast curing epoxy resin system for a glass fiber pultrusion frame and a preparation method of the fast curing epoxy resin system. Comprising the following components in parts by weight: 50-75 parts of polybutadiene epoxy resin, 50-75 parts of glycidyl ether type epoxy resin, 15-30 parts of modified toughening particles, 8-12 parts of a curing agent, 30-40 parts of liquid crystal epoxy resin, 25-30 parts of B144 epoxy resin, 10-20 parts of inorganic whiskers, 15-20 parts of a dendritic polymer and 20-25 parts of a high polymer waterproof emulsion. By adding the high polymer waterproof emulsion and the dendritic polymer, the wear-resistant effect of an epoxy resin system is efficiently improved, mechanical connection is facilitated, glass fiber preparation work is carried out, and the working quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber processing, in particular to a fast curing epoxy resin system for a glass fiber pultrusion forming frame and a preparation method thereof. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high temperature melting, wire drawing, winding, weaving and other processes. The diameter of the monofilament is several microns to twenty microns. It consists of hundreds or even thousands of monofilaments. Glass fibers are usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national e...
