Pressure-proof, wear-resistant and age-proof ethylene-propylene-diene synthetic rubber and preparation method

Abstract

The invention discloses a pressure-proof, wear-resistant and age-proof ethylene-propylene-diene synthetic rubber and a preparation method. The pressure-proof, wear-resistant and age-proof ethylene-propylene-diene synthetic rubber is prepared from the following raw materials: ethylene-propylene-diene 3092, zinc oxides, stearic acids, white carbon black, light calcium carbonate, sulfur, an accelerator tetramethylthiuram disulfide (TMTD), the accelerator 2-mercaptobenzothiazole (M), an antioxidant poly(1,2-dihydro-2,2,4-trimethyl-quinoline) (RD), the antioxidant 2-mercaptobenzimidazole (MB), rubber engine oil, black metal peroxide dicumyl peroxide (DCP), the antioxidant CHEMKY1010 and an ultraviolet absorbent CHEM-UV531(C-81). The pressure-proof, wear-resistant and age-proof ethylene-propylene-diene synthetic rubber is simple to prepare, low in production cost, widely applicable, pressure-proof, wear-resistant, age-proof, long in service life and fadeless.

Description

technical field [0001] The invention relates to a composition of rubber or its derivatives, in particular to a layer material EPDM color colloidal particle used for auxiliary decoration of plastic sports venues, which is obtained by copolymerizing three monomers of ethylene-propylene-non-conjugated diene A pressure-resistant, wear-resistant and anti-aging EPDM synthetic rubber and a preparation method thereof are disclosed. Background technique [0002] In 1955, people conducted in-depth research on new catalytic technology and successfully copolymerized ethylene and propylene into an elastomer, that is, a fully saturated rubber - binary ethylene propylene rubber, thus creating the era of human use of saturated rubber , it has outstanding heat resistance, ozone resistance, weather resistance, aging resistance and electrical insulation properties. However, with the continuous development of technology and industry, the requirements for its use are getting higher and higher. S...

AI Technical Summary

Problems solved by technology

At present, domestic EPDM EPDM rubber products generally have a tensile length of 4.5MPa, a wear-resistant hardness of 55±5 Shore A, and a density of ≤1.45×10 3 Kg / m 3 The pressure resistance is not high. If you want to increase its tensile length, wear resistance hardness and pressure resistance, you can only increase the content of virgin rubber, and the virgin rubber is imported and expensive.
