Acid-alkali resistant rubber material formula

Abstract

The invention discloses an acid-alkali resistant rubber material formula, comprising the following components in parts by weight: 100 parts of ethylene propylene rubber, 50 parts of styrene butadiene rubber, 40 parts of chlorinated polyethylene, 50 parts of neoprene, 7 parts of zinc oxide, 3 parts of magnesium oxide, 25 parts of butadiene-styrene rubber, 3 parts of an acid-absorbing agent DHT-4A, 7 parts of decabrominated dipheny ethane, 4 parts of microcrystalline paraffin, 4 parts of chlorinated polyethylene, 10 parts of barium carbonate, 8 parts of vermicular carbon, 8 parts of polyglycerol ricinoleate, 0.2 part of wintergreen oil, 6 parts of 3-hydroxybenzoic acid, 12 parts of carbon black, 2 parts of lauryl alcohol sulfate, 6 parts of plant saponin, 0.3 part of ginger juice, 2 parts of white mica powder, 0.2 part of terpineol, 3 parts of sulfur, 15 parts of naphthenic oil and 1 part of methacrylic ester. The rubber manufactured according to the acid-alkali resistant rubber material formula disclosed by the invention is hardly corroded, and is oil-resistant, high-pressure-resistant and acid-alkali resistant.

Description

technical field [0001] The invention relates to a chemical product, in particular to an acid and alkali resistant rubber material formula. Background technique [0002] The rubber coating layer of the existing ordinary rollers cannot work in chemicals such as acid, alkali, and salt solution. When the rubber coating layer of ordinary rollers is in contact with acid, alkali, and salt solution, it will cause corrosion, cause rubber swelling, and produce rubber molecules. Fracture, depolymerization, and decomposition and dissolution of compounding agents 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 occur due to the attack of ozone. So that the corrosion completely loses the ability to work. [0003] With the continuous development of industrial production, the use of rollers is required to be more and more widely used, and the requiremen...

Problems solved by technology

The lubrication system widely used in metal smelting machinery and equipment contains acid and alkali, which has a relatively obvious penetration force on rubber seals, causing rubber parts to expand and cannot be sealed to affect normal equipment operation. There is no ideal acid and alkali resistance in the market. Rubber parts
