Abstract

The invention discloses a nylon corrugated pipe, comprising the following raw materials in parts by weight: 1-2 parts of phosphite ester, 1-2 parts of hexabromocyclododecane, 10-14 parts of nylon 610, 0.4-1 part of di-methylol di-hydroxy ethylene urea, 1-2 parts of chromic carbonate, 1-2 parts of 2,2-dithienyl methyl glycolate, 2-4 parts of epoxy ethylhexyl stearate, 2-4 parts of hexagonal boron nitride, 6-8 parts of montmorillonite powder, 2-3 parts of polyvinylidene fluoride, 2-3 parts of dipropylene glycol, 1-2 parts of ammonium dihydrogen phosphate, 90-96 parts of polypropylene and 5-7 parts of compound additive. The corrugated pipe disclosed by the invention has good high temperature resistance, good acid and alkali corrosion resistance, strong shock resistance, excellent physical property, good tenacity, high surface hardness, and long service life, and is especially applicable to being used as a dry corrugated pipe material under a high-temperature condition.

Description

technical field [0001] The invention mainly relates to the field of pipe materials, in particular to a nylon corrugated pipe and a preparation method thereof. Background technique [0002] Polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties. The absolute value of the mechanical properties of polypropylene is higher than that of polyethylene, but it is still a relatively low variety in plastic materials, and its tensile strength can only reach 30 MPa or a slightly higher level. Polypropylene with a larger isotactic index has higher tensile strength, but as the isotactic index increases, the impact strength of the material decreases, but it does not change after falling to a certain value. [0003] Temperature and loading rate have a great influence on the toughness of polypropylene. When the temperature is higher than the glass transition temperature, the impact fracture is ductile fracture, and below the glass transitio...
