Abstract

The invention discloses polyethylene bellows. The polyethylene bellows are prepared from 100-120 parts by weight of polyethylene resin, 3-5 parts by weight of triethoxyvinylsilane, 1-2 parts by weight of stearic acid, 5-7 parts by weight of powdered steatile, 6-8 parts by weight of calcium carbonate, 4-6 parts by weight of paraffin, 12-14 parts by weight of tetrabromobisphenol S bis(2,3-dibromopropyl)ether, 6-8 parts by weight of antimonous oxide, 0.5-0.7 parts by weight of pentaerythritol tetrakis(3-(3',5'-ditertbutyl-4'-hydroxyphenyl)propionate), 0.2-0.3 parts by weight of salicylamidophthalimide and 2-3 parts by weight of dibutyltin laurate-maleate.

Description

technical field [0001] The invention belongs to the technical field of corrugated pipe materials, in particular to a polyethylene corrugated pipe. Background technique [0002] The bellows is a common elastic part, which uses the elasticity of the material to achieve the required function, changes the shape and size of the element under the external load, and returns to the original state when the load is removed, so as to realize the measurement , connection, conversion, compensation, isolation, sealing, shock absorption and other functions. At present, bellows are widely used in automobiles, and bellows for automobiles require materials with good flame retardancy, heat resistance, insulation and toughness. In the prior art, polyethylene is mainly used as the material of the corrugated pipe, but there is a defect that it is easy to burn, and needs to be improved. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of t...
