High-waterproof anti-leakage sealing rubber material and preparation method thereof

Abstract

The invention discloses a high waterproof and anti-leakage sealing rubber material, which is composed of the following raw materials in parts by weight: succinic anhydride 1-2, anti-aging agent rd1-2, 2-aminoethyl heptadecenyl imidazole Phenyl 1‑2, butadiene rubber 120‑140, attapulgite powder 10‑12, abietyl alcohol 2‑4, vulcanizing agent PM0.7‑1, bone char 3‑4, dibutyl maleate 4‑5 , sodium metasilicate 1‑3, accelerator TT1‑2, N, N‑diethylaniline 0.5‑1, potassium hydrogen tartrate 1‑2, vanadium acetylacetonate 0.5‑1, lithium hydroxide 0.1‑0.2, waterproofing aid Agent 3‑4; the present invention adopts hexahydrophthalic anhydride to cross-link modified stearic acid, and then carry out surface treatment by 1H, 1H, 2H, 2H perfluorodecyltriethoxysilane to obtain highly water-resistant The auxiliary agent can effectively improve the hydrophobicity of the finished material and prevent rubber aging and corrosion. The rubber material of the present invention has strong leakage resistance, and is especially suitable for use in underground water pipes, ships and other fields, with long service life and weather resistance Good sex.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high waterproof and anti-leakage sealing 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 nitri...

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
