Problems solved by technology

The most traditional reinforcing agents in the rubber industry have always been carbon black and white carbon black. Although they have a certain reinforcing effect, these two reinforcing agents have very low apparent densities. When added to rubber, it is easy to produce Feiyang, heavy processing pollution, long processing time, high energy consumption for mixing, and the carbon black reinforced product is a single black color, and these two reinforcing agents are difficult to endow the product with higher hardness and better air resistance sex etc.

Abstract

The invention discloses a novel waterproof rubber material prepared from the following raw materials in parts by weight: 9-11 parts of polyethylene glycol terephthalate, 2-5 parts of trioctyl citrate, 2-4 parts of softener, 22-25 parts of polyacrylonitrile, 1-2 parts of sodium diacetate, 12-15 parts of graphite, 3-4 parts of coal ash microspheres, 0.5-1 part of sodium dodecyl sulfate, 40-60 parts of liquid nitrile rubber, 0.5-1 part of methylacrylic acid, 50-60 parts of nitrile rubber, 20-25 parts of butadiene styrene rubber, 5-8 parts of nano-silicon sol, 3-4 parts of tetramethyl thiuram disulfide, 2-3 parts of diglycol, 6-8 parts of VAE emulsion, 14-16 parts of filler, 5-8 parts of barium sulfate, 7-10 parts of magnesium hydroxide, and 0.2-0.4 part of calcium propionate. The novel waterproof rubber material has favorable waterproofness, is acid-resistant, oil-resistant and flame-resistant, and can well meet requirements in production.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a novel waterproof rubber material. Background technique [0002] Rubber material is a kind of polymer material that can quickly recover deformation under large deformation. It is one of the important basic industries of the national economy, providing light industrial rubber products for daily and medical indispensable in people's daily life; for mining , transportation, construction, machinery, electronics and other heavy industries and emerging industries provide various 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 requirements. Rubber is...
