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 environmental-friendly alumina sol modified rubber material which is composed of the following raw materials in parts by weight: 1-2 parts of an anti-aging agent 4010, 1-1.4 parts of a vulcanizing agent MOCA, 120-160 parts of butadiene rubber, 10-12 parts of dioctyl azelate, 3-5 parts of modified alumina sol, 10-14 parts of organobentonite, 1-2 parts of aluminum oxide, 3-4 parts of barium stearate, 0.6-1 part of benzyl triethylammonium bromide, 4-7 parts of polyvinylidene fluoride, 1-2 parts of isopropyl palmitate, 0.7-1 part of vinyl trimethoxy silane, 1-2 parts of diacetone-acryloamide and 0.1-0.3 part of dibasic lead phosphate. According to the environmental-friendly alumina sol modified rubber material disclosed by the invention, the alumina sol is prepared by taking aluminum isopropoxide as a raw material, polybenzimidazole and ethyecellulose are added for mixing, divinyl benzene is adopted for performing crosslinking modification, the flexibility, the weather resistance and the viscosity of the sol are further improved, the compatibility between each raw material and rubber is enhanced, and the stability of finished rubber is improved.
Description
Technical field [0001] The invention relates to the technical field of rubber, in particular to an environmentally friendly aluminum sol modified rubber material and a preparation method thereof. Background technique [0002] Butadiene rubber is short for cis-1,4-polybutadiene rubber, and its molecular formula is (C 4 H 6 ) n . Butadiene rubber is a structured synthetic rubber formed by polymerization of butadiene, and its cis structure content is more than 95%. According to the different catalysts, it can be divided into nickel-based, cobalt-based, titanium-based and rare-earth (neodymium) 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, abrasion resistance and elasticity after vulcanization, less heat under dynamic load, and good aging resistance. It is easy to use with natural rubber, neoprene rubber or nitrile rubber. Butadie...
