Abstract

The invention discloses an anticorrosive antimicrobial corrugated pipe which comprises the following raw materials in parts by weight: 0.6-1 part of polyhexamethyleneguanidine, 1-2 parts of copper 8-hydroxyquinoline, 1-2 parts of aluminum isopropoxide, 1-2 parts of formamide, 2-3 parts of polypropylene glycol adipate, 1-2 parts of polyoxytetramethylene glycol, 90-93 parts of polypropylene, 2-3 acrylonitrile-styrene copolymer, 6-10 parts of light calcium carbonate, 1-2 parts of N,N-dimethyl cyclohexylamine, 0.8-1 part of ammonium metavanadate, 1-2 parts of dimethyl polysiloxane and 5-6 parts of composite assistant. The corrugated pipe disclosed by the invention has excellent acid resistance, alkali resistance and corrosion resistance, is not influenced by moisture and soil ph value, is convenient to construct and saves the cost; and the added polyhexamethyleneguanidine and copper 8-hydroxyquinoline have favorable antimicrobial and anticorrosive effect.

Description

technical field [0001] The invention mainly relates to the field of pipe materials, in particular to an anti-corrosion and anti-bacterial 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 ...
