Abstract

The invention discloses a high-performance corrugated pipe. The high-performance corrugated pipe is formed by, by weight percent, 80 to 100 parts of polyethylene resin, 25 to 35 parts of calcium carbonate, 0.5 to 1 parts of titanate, 1 to 2 parts of stearic acid, 6 to 8 parts of tetrabromobisphenol S bis(2,3-dibromopropyl)ether, 3 to 5 parts of antimonous oxide, 0.5 to 0.7 part of pentaerythritol tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate] pentaerythritol ester, 0.2 to 0.3 part of salicin acylamino phthalimide and 1 to 2 parts of lauric acid dibutyltin maleate. The calcium carbonate, the titanate, the stearic acid, the tetrabromobisphenol S bis(2,3-dibromopropyl)ether, the antimonous oxide, the pentaerythritol tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester, the salicin acylamino phthalimide and the lauric acid dibutyltin maleate are mixed in a thermal mixing machine, then the polyethylene resin is added to perform extrusion and granulation, granules are added to a single screw extruder to be extruded, a pipeline is formed, and the corrugated pipe is obtained.

Description

technical field [0001] The invention belongs to the technical field of bellows materials, in particular to a high-performance bellows. 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 of insufficient bending performance, which needs to be improved. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of...
