Problems solved by technology

However, the hardness of graphite is low and it is easy to wear and tear. Only using graphite as a lubricating component is not conducive to maintaining long-term lubrication and anti-friction performance, and the effect of prolonging the service life of rubber products is limited. It is necessary to improve it

Abstract

The invention discloses an automobile sealing strip rubber material with the effects of restraining bacteria and removing abnormal smells. The automobile sealing strip rubber material is prepared from, by weight, 100-120 parts of ethylene propylene diene monomer, 30-50 parts of white carbon black, 10-15 parts of shell powder, 2-4 parts of blumea oil, 2-4 parts of zinc oxide, 1.5-2.5 parts of sulphur S80, 1.5-2.5 parts of antiager MB, 0.3-0.5 part of accelerant TMTD, 0.03-0.05 part of tetradecyl dimethyl benzyl ammonium, 0.1-0.15 part of glycerol monolaurate, 3-5 parts of methyltrimethoxysilane, 0.5-1 part of tetrabutyl titanate, 0.15-0.25 part of titanate coupling agent NDZ-401, 6-8 parts of nano-graphite powder and 20-30 parts of castor oil. The rubber material is good in anti-abrasion effect and durable in anti-friction performance, has the effects of restraining bacteria and removing abnormal smells, and has the advantages of being long in service life, good in sealing performance and good in sanitation when used as an automobile sealing strip material.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber material for antibacterial and deodorizing automobile sealing strips and a preparation method thereof. Background technique [0002] As an indispensable and important polymer material in the national economy and daily life, rubber has excellent physical and mechanical properties, elasticity and processing properties, and plays an irreplaceable role in many important fields such as automobile transportation, mining, and chemical industry. . Tribological performance is a very important indicator of rubber materials, related to the wear resistance of rubber tire products, the wear resistance of seals, etc. Improving the wear resistance of rubber materials is conducive to increasing its service life, and can bring considerable economic and social benefits in terms of saving energy, materials, lubricants, etc. [0003] At present, one of the more effective methods ...
