Problems solved by technology

The most traditional reinforcing agent in the rubber industry has always been carbon black. Although it has a certain reinforcing effect, both of these two reinforcing agents have very low apparent density. When added to rubber, it is easy to generate flying and process pollution. Heavy, at the same time the processing time is long, the energy consumption of mixing is large, and the carbon black reinforced product is a single black, and these two reinforcing agents are difficult to endow the product with higher hardness, better resistance, etc.

Abstract

The invention discloses a stretching-resisting rubber material. The stretching-resisting rubber material is prepared from the following raw materials in parts by weight: 1 to 3 parts of peracetic acid, 2 to 3 parts of an accelerator DPG (Diphosphoglyceric Acid), 4 to 6 parts of silicone powder, 2 to 4 parts of ascorbic acid, 20 to 25 parts of polyacrylonitrile, 10 to 15 parts of graphite, 3 to 4 parts of fly ash microsphere, 0.5 to 1 part of sodium dodecyl sulfate, 40 to 50 parts of liquid nitrile butadiene rubber, 0.5 to 1 part of methacrylic acid, 50 to 60 parts of nitrile butadiene rubber, 20 to 25 parts of butadiene styrene rubber, 2 to 3 parts of an anti-ageing agent, 0.5 to 1 part of hydroxypropyl methyl cellulose ether, 1 to 1.5 parts of lauric acid, 15 to 20 parts of expanded perlite, 8 to 15 parts of an ethylene-vinyl acetate copolymer, 15 to 20 parts of mineral slag powder and 3 to 4 parts of a vulcanizing agent. The stretching-resisting rubber material has a relatively strong stretching-resisting performance and is suitable for automobile tires.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a stretch-resistant rubber material. Background technique [0002] Rubber material is a polymer material that can quickly recover from deformation under large deformation. It is one of the important basic industries of the national economy. It provides light industrial rubber products for daily use and medical use that are indispensable in people's daily life; for mining , Transportation, construction, machinery, electronics and other heavy industries and emerging industries provide a variety of rubber production equipment or rubber parts, which are widely used. In recent years, the rapid development of the rubber industry has put forward higher requirements for rubber products, and rubber materials must develop in the direction of functionalization, refinement and diversification. The traditional single rubber material can no longer fully meet the rapidly developing application ...
