Acid and alkali resistant rubber material

Abstract

The invention discloses an acid and alkali resistant rubber material, made from special rubber, reclaimed rubber, porous powder quartz, carbon black, a titanate coupling agent, organic silicon resin, sulfur, a flow modifier, and a catalyst. Compared with the prior art, the acid and alkali resistant rubber material has the advantages that the reclaimed rubber good in impact resistance is combined with the special rubber, the impact resistance of the material is enhanced while acid and alkali resistance and ageing resistance of the special rubber are maintained, a rubber product made by mixing the material with other materials in a high-temperature environment is good in high temperature resistance, the weight of the rubber product after being corroded by acid and alkali has slight change, tensile strength bears low impact, and acid and alkali resistance is good; as the reclaimed rubber and the porous powder quartz are used, production cost is greatly reduced and the material is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of rubber preparation, in particular to an acid and alkali resistant rubber material. Background technique [0002] Because silicone rubber products have excellent comprehensive performance and good technical and economic effects, they have been widely used in aviation, aerospace, atomic energy, electrical appliances, electronics, instruments, automobiles, machinery, metallurgy, chemical industry, medical and health, and daily life. Application, in industrial production, the connection between some equipment and containers is usually made of ordinary rubber materials, and ordinary rubber materials generally have poor temperature resistance and poor ozone aging resistance, which usually leads to uniform aging of some pipelines and storage equipment , being corroded by acid and alkali, which requires regular replacement or maintenance of these equipments. If the maintenance is not timely, it will cause other c...

[0002] Because silicone rubber products have excellent comprehensive performance and good technical and economic effects, they have been widely used in aviation, aerospace, atomic energy, electrical appliances, electronics, instruments, automobiles, machinery, metallurgy, chemical industry, medical and health, and daily life. Application, in industrial production, the connection between some equipment and containers is usually made of ordinary rubber materials, and ordinary rubber materials generally have poor temperature resistance and poor ozone aging resistance, which usually leads to uniform aging of some pipelines and storage equipment , being corroded by acid and alkali, which requires regular replacement or maintenance of these equipments. If the maintenance is not timely, it will cause other consequences such as dripping of materials, which not only causes waste of rubber resources, but the price of existing acid and alkali resistant rubber materials is relatively high. High, difficult to be widely promoted
