Problems solved by technology

Nowadays, rubber mats are widely used in industry and life due to their insulation properties, but with the development of industry, the requirements for technology are getting higher and higher, and rubber will gradually undergo physical and chemical damage due to the influence of heat, oxygen, and light factors. The chemical change reduces the performance and loses its own use. This phenomenon is called the aging of rubber.
Some working environments will encounter strong acid items, which will reduce the service life, so the requirements for rubber mats are getting higher and higher, and the technology must be further improved

Abstract

A rubber gasket is prepared from the following raw materials in parts by weight: 15-35 parts of ethylenie-propylene-diene rubber, 8-16 parts of paraffin oil, 3-6 parts of polyamide wax micro powder, 2-5 parts of boron carbide, 26-56 parts of 1502 type butadiene styrene rubber, 8-24 parts of dibutyl ester, 2-6 parts of an accelerant TMTD, 3-6 parts of an antiager RD, 12-26 parts of carboxyl hydrogenated nitrile-butadiene rubber, 1-4 parts of a crosslinking agent, 9-15 parts of potassium tripolyphosphate, 6-13 parts of phenol, 8-16 parts of fluorinated silicone rubber and 2-4 parts of graphite powder. The rubber gasket has the benefits that the oil resistance and the water resistance are higher, and the age resistance is excellent.

Description

technical field [0001] The invention relates to a rubber pad. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. Rubber not only provides people with daily and medical light industrial rubber products that are indispensable in daily life, but also provides heavy and emerging industries such as mining, transportation, construction, machinery, and electronics. Various rubber-made production equipment or rubber parts. Nowadays, rubber mats are widely used in industry and life due to their insulation properties, but with the development of industry, the requirements for technology are getting higher and higher, and rubber will gradually undergo physical and chemical damage due to the influence of heat, oxygen, and light factors. The chemical change reduces the performance and loses its own use. This phenomenon is called the aging of rubber. Some working environments will encounter strong acid items, which will re...
