PVC composite material for drainage pipeline and preparation method of PVC composite material

Abstract

The invention discloses a PVC composite material for a drainage pipeline and a preparation method of the PVC composite material, and relates to the technical field of drainage pipeline production formulas. A tire tread is prepared from the following raw materials, namely butadiene styrene rubber composite materials, in parts by mass: 80-95 parts of butadiene styrene rubber, 8-10 parts of phenolic resin, 3-8 parts of 2,6-di-tert-butyl-4-methylphenol, 2-5 parts of aedelforsite, 3-6 parts of magnesium carbonate, 4-8 parts of calcium stearate, 1-3 parts of trioctyltrimellitate, 1.5-4 parts of diphenyl silanediol, 2-7 parts of coumarone resin, 0.5-1.5 parts of rosin, 1-3 parts of maleic anhydride, 2-5 parts of ammonium persulfate, 1.5-3 parts of phthalic anhydride, 0.5-2 parts of sulfur and 3-8 parts of nano calcium carbonate. The PVC composite material for the drainage pipeline is easily available in raw materials, novel in formula design and simple in production process; and the obtained PVC composite material for the drainage pipeline has strong high temperature resistance, wear resistance and ageing resistance and good mechanical properties.

Description

Technical field:

[0001] The invention relates to the technical field of production formula for drainage pipes, in particular to a PVC composite material for drainage pipes and a preparation method thereof. Background technique:

[0002] Styrene-butadiene rubber is a copolymer of butadiene and styrene, its performance is close to that of natural rubber, and it is the most widely used synthetic rubber. Its advantages are that its wear resistance, aging resistance and heat resistance exceed natural rubber, and its texture is more uniform than natural rubber. It is mainly used to replace natural rubber to make tires, rubber sheets, rubber hoses and other general products; but it also has poor elasticity. , The shortcomings of poor flex and tear resistance.

[0003] At present, although a variety of styrene-butadiene rubber materials used in tires have been developed, they still cannot meet the needs. How to prepare a kind of styrene-butadiene rubber material for tire treads wit...
