Abstract

The present invention relates to one kind of low shrinking glass fiber reinforced unsaturated polyester resin material (DMC, BMC and SMC) and its application in making fire-fighting equipment. The low shrinking glass fiber reinforced unsaturated polyester resin material consists of unsaturated polyester resin 28-32 weigh portions, low shrinking agent 11-15 weigh portions, 6-12 mm glass fiber 13-21 weigh portions, 3-5 mm ceramic fiber 7-11 weigh portions, filler 60-70 weigh portions, initiator 0.3-0.6 weigh portions, thickener 0.5-1 weigh portion, and flame retardant 11-15 weigh portions. The low shrinking glass fiber reinforced unsaturated polyester resin material is used in making fire-fighting water gun joint with high mechanical strength, high size precision, high impact resistance and other features.

Description

technical field [0001] The invention relates to a new batching process of low-shrinkage unsaturated polyester resin glass fiber reinforced molding compound (DMC, BMC, SMC) and its application in the fire-fighting equipment manufacturing industry. The invention belongs to the technical field of low-shrinkage unsaturated polyester resin glass fiber reinforced molding compound and its new application. Background technique [0002] In order to meet the needs of fire protection work, the current industrial and civil buildings, including factory workshops, commercial buildings, stadiums, conference buildings, office buildings, airports, stations and residential buildings, etc., have been equipped with fire hydrant boxes. Among them, the fire hose nozzle and fire hose interface made of cast aluminum are the most important fire fighting equipment. Due to the rising price of non-ferrous metals and the fact that fire-fighting equipment is not allowed to be locked, these aluminum fire...
