Abstract

The invention provides a composite for fire hoses and a preparation method of the composite. The composite is prepared from components in parts by weight as follows: 100 parts of sucrose polyester modified polyvinyl chloride resin, 60-70 parts of a fluorine-containing organosilicone modified polyurethane polymer, 40-50 parts of bisphenol A polycarbonate, 30-40 parts of polyphenyl ether, 10-15 parts of polyacrylamide, 10-15 parts of acrylate, 10-12 parts of medium chain triglyceride, 8-12 parts of polyvinyl acetal, 8-12 parts of dibutyl phthalate, 2-3 parts of calcium stearate, 2-3 parts of cadmium stearate, 1-2 parts of 1,4-butanediol diacrylate and 1-2 parts of dibutyltin dilaurate. Main raw materials comprise sucrose polyester modified polyvinyl chloride resin, the fluorine-containing organosilicone modified polyurethane polymer, bisphenol A polycarbonate and polyphenyl ether, and the composite has good mechanical performance, water resistance, wear resistance and aging resistance through cooperation of the four raw materials and the auxiliary function of auxiliary materials.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a composite material for a fire-fighting hose and a preparation method thereof. Background technique [0002] Fire hose is the most common kind of fire-fighting equipment. It is a hose used to transport flame-retardant liquids such as high-pressure water or foam. The traditional fire hose is lined with rubber and wrapped with linen fabric on the outer surface. Popular fire hoses are made of polymeric materials such as polyurethane. [0003] With the development of large-scale cities and high-rise residential buildings, there are more and more high-rise buildings and higher requirements for fire-fighting equipment. As far as the fire hose is concerned, it is required to have high mechanical properties, water resistance, wear resistance and aging resistance to match it. [0004] There are two main manufacturing methods of the existing fire hoses: the first method ...
