Problems solved by technology

However, these rubbers have poor acid resistance and aging resistance. In order to solve this problem, anti-aging agents or other additives will be added to the rubber matrix during tire production to improve the aging resistance and strength of the tire.
But the corrosion resistance of this rubber composition added with anti-aging agent is still poor, it is easy to be corroded by acid and alkali, and the service life is low

Abstract

The invention discloses an acid-base resistant composite material as well as a preparation method and an application thereof. The acid-base resistant composite material is prepared from components inparts by weight as follows: 80-150 parts of rubber, 14-18 parts of dimethylol dihydroxy ethylene urea, 8-15 parts of octyl diphenyl phosphite, 9-12 parts of tert-butyl cyclopropanecarboxylate and 6-9parts of propiconazole. The acid-base resistant composite material is prepared from the rubber, dimethylol dihydroxy ethylene urea, octyl diphenyl phosphite, tert-butyl cyclopropanecarboxylate and propiconazole, has the advantages of acid-base resistance, aging resistance and flame retardance, and the service life is prolonged; the preparation process is low and production is facilitated.

Description

technical field [0001] The invention relates to a composite material, in particular to an acid and alkali resistant composite material and its preparation method and application. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have high load-carrying performance, traction performance, and cushioning performance; Abrasion and flex resistance, as well as low rolling resistance and heat generation. The main material for making tires is rubber, which is divided into natural rubber, nitrile rubber, styrene-butadiene rubber, butyl rubber, etc. However, these rubbers have poor acid resistance and aging resistance. In order to solve this problem, anti-aging agents or other additives are added to ...
