Rubber product with high alkaline resistance and preparing method of rubber product

Abstract

The invention discloses a rubber product with high alkaline resistance. The rubber product is prepared from, by weight, 50-60 parts of natural rubber, 10-20 parts of neoprene, 5-10 parts of polyethylene wax, 5-10 parts of linoleic acid, 2-5 parts of octyl-phenolic curing resin, 1-2 parts of curing resin, 5-20 parts of ethylene propylene rubber, 5-20 parts of fluorous rubber, 0.5-1 part of magnesium stearate, 5-10 parts of barium sulfate, 5-10 parts of vanadyl acetylacetonate, 1-5 parts of aluminum hydroxide, 5-10 parts of tributyl phosphate, 10-20 parts of polymethyl methacrylate, 5-20 parts of polyving akohol, 5-10 parts of titanium dioxide, 10-20 parts of methyl methacrylate, 5-10 parts of anti-aging agents and 5-10 parts of plasticizer. The invention further discloses a preparing method of the rubber product. The alkaline resistance of the rubber product is improved through optimization of the formula.

Description

technical field [0001] The invention relates to a production method of rubber products, in particular to a rubber product with high alkali resistance and a preparation method thereof. Background technique [0002] Rubber is the latex taken from plants such as rubber trees and rubber grasses. After processing, it is a material with elasticity, insulation, and impermeability to water and air. High elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. [0003] Ordinary rubber materials cannot work in acid-base, salt solution and other chemicals for a long time. Ordinary rubber materials will cause corrosion when they contact with acid-base, salt solution and chemicals, causing rubber swelling, rubber molecular br...

AI Technical Summary

Problems solved by technology

[0003] Ordinary rubber materials cannot work in acid-base, salt solution and other chemicals for a long time. Ordinary rubber materials will cause corrosion when they contact with acid-base, salt solution and chemicals, causing rubber swelling, rubber molecular breakage, depolymerization and compounding agent breakdown. Decomposition, dissolution and other phenomena lead to a significant decrease in its mechanical strength and physical properties, and the rubber layer gradually becomes sticky, oxidized, hardened, embrittled, cracked, etc., and cracks are generated by the attack of ozone, so that the corrosion completely loses its working ability.

[0004] Rubber with strong acid and alkali resistance includes nitrile rubber and fluororubber. Fluororubber has the characteristics of high temperature resistance, oil resistance and corrosion resistance of various chemicals, but fluororubber is expensive, and wide-scale application will lead to increased cost. Rubber does not have other properties, and also cannot meet industrial requirements
