Problems solved by technology

[0003] At present, the main disadvantages of finished materials made of single butadiene rubber are poor wet skid resistance, low tear strength and tensile strength, high cold flow, and poor processability. Traditional methods to improve these shortcomings are to use a variety of Rubber compounding, the purpose of this invention is to use a single butadiene rubber, blended with a variety of additives to achieve the effect achieved by compound rubber, and to make up for the shortcomings of traditional single butadiene rubber products

Abstract

The invention discloses an elastic anti-buffer rubber material, which is composed of the following raw materials in parts by weight: magnesium oxide 0.1-0.3, zinc oxide 1-2, accelerator TMTD 0.8-1, sulfur 1-2, anti-aging Agent AW1-2, tributyl citrate 7-9, buffer additive 5-7, medical stone powder 2-4, ethylene glycol monobutyl ether 4-6, propylene glycol alginate 1-2, polybenzimidazole Fiber 3-4, oxidized polyethylene wax 2-4, 8-hydroxyquinoline copper 0.7-1, silane coupling agent KH5600.1-0.2, butadiene rubber 100-140, wollastonite powder 10-12, dodecane Base trimethyl ammonium chloride 0.7-1; The present invention adopts polyurethane thermoplastic elastomer as the main body of the anti-buffer material, which not only has good impact strength, but also can improve various mechanical properties of finished rubber and improve weather resistance. The anti-buffer rubber material invented has good flexibility and high resilience, and can be used as a variety of safety protection buffer materials. It has no volatilization of toxic and harmful components, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an elastic anti-buffer rubber material and a preparation method thereof. Background technique [0002] Butadiene rubber is the abbreviation of cis-1,4-polybutadiene rubber, and its molecular formula is (C4H6)n. Butadiene rubber is a synthetic rubber with regular structure formed by the polymerization of butadiene, and its cis structure content is more than 95%. According to different catalysts, it can be divided into nickel-based, cobalt-based, titanium-based and rare earth-based (Nd-based) butadiene rubber. Butadiene rubber is the second largest synthetic rubber after styrene-butadiene rubber. Compared with natural rubber and styrene-butadiene rubber, it has excellent cold resistance, wear resistance and elasticity after vulcanization, less heat generation under dynamic load, and good aging resistance. It is easy to use with natural rubber, neoprene or nitrile rubber. Butadien...
