Abstract

The invention discloses novel flame-retardant wear-resistant rubber. The novel flame-retardant wear-resistant rubber is prepared from the following raw materials in parts by weight: 20-50 parts of EPDM (Ethylene-Propylene-Diene Monomer), 5-10 parts of zinc oxide, 5-10 parts of magnesium oxide, 3-6 parts of titanium dioxide, 10-15 parts of carbon black, 6-12 parts of dicumyl peroxide, 5-15 parts of boric acid, 2-6 parts of dioctylterephthalate, and 3-5 parts of sulphur. The formula is more reasonable. The molecular weight is higher by replacing original dibutyl phthalate with dioctylterephthalate through the regulation of proportion; by regulating the usage amount of dicumyl peroxide, the system breaks through the technical limit that a little sulphur and a large amount of peroxide are crosslinked in the formula of the traditional rubber technique, the ozone resistance property of finished produced prepared from the flame-retardant wear-resistant rubber can be obviously enhanced through synergic crosslinking of the sulphur and the peroxide which have basically equal parts.

Description

Technical field [0001] The invention relates to the technical field of rubber formulations, in particular to a novel flame-retardant and wear-resistant rubber. Background technique [0002] There are thousands of formulas and manufacturing methods for rubber compositions, which are often equipped with different material formulas according to different usage requirements. At present, the common general components with weather resistance and wear resistance are nitrile rubber 100, N330 carbon black 65, dibutyl 20, sulfur 1.8, accelerator 2.5, flow agent 2, antioxidant 4, zinc oxide 5, paraffin wax 1.5-2.5. Another composition is nitrile rubber 100, N330 carbon black 35, N220 carbon black 30, dibutyl 20, sulfur 0.5, dicumyl peroxide 3, accelerator 1.5, flow agent 2, antioxidant 4, oxidation Zinc 5, paraffin wax 1.5-2.5. The rubber products made of these two components are of low quality, are not weather-resistant, unused, have low fatigue resistance, are easy to crack, and are no...
