Abstract

The invention relates to a fireproof polyvinyl chloride material which comprises 110 parts of polystyrene, 1 part of silica white, 1 part of phthalate, 2 parts of nano activated calcium carbonate, 3 parts of polystyrene, 20 parts of ultra-low density polyethylene, 4 parts of zinc borate, 3 parts of polypropylene cellulose, 5 parts of triethyl phosphate, 4 parts of bromine flame retardant, 12 parts of antioxidant and 3 parts of dibutyl phthalate. The polyvinyl chloride composite material has the advantages of favorable flowability, favorable flame retardancy, higher viscosity, better processing flowing property, favorable heat resistance, favorable weather resistance, favorable ultraviolet resistance, high average application temperature, mature production and extrusion technique, extremely high stress cracking resistance, low production cost, tube cost saving and higher load-bearing capacity, and is an environment-friendly novel polyvinyl chloride composite material.

Description

technical field [0001] The invention relates to a chemical product, especially a fireproof polyvinyl chloride material. Background technique [0002] At present, due to the excellent crack resistance, low temperature resistance, hygienic and non-toxic, and chemical medium corrosion resistance of high-density polyethylene pipes [0003] and easy installation. However, because its own material does not have heat resistance, pure polyvinyl chloride has certain defects in mechanical strength and flame retardancy, which limits its use. At present, the known patented technology and practical technology only partially solve the problem of its heat resistance, and none of them can solve the problem of both heat resistance and pressure resistance. The cost of the pipe is very high, and the waste of resources is serious. big. In order to improve the flame retardancy and mechanical properties of PVC, it is usually necessary to add other components, such as flame retardants, fillers,...
