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 a high-durability mildewproof automobile sealing strip rubber material. The material is prepared from, by weight, 100-120 parts of ethylene propylene diene monomer, 40-60 parts of white carbon black, 4-8 parts of hectorite, 0.5-1 part of cinnamon oil, 0.5-1 part of zanthoxylum 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, 3-5 parts of methyltrimethoxysilane, 0.5-1 part of caprylic capric triglyceride, 0.5-1 part of tetrabutyl titanate, 0.15-0.25 part of titanate coupling agent NDZ-401, 6-8 parts of nanometer graphite powder, 20-30 parts of castor oil and 0.5-1 part of honey. The rubber material is good in wear-resisting effect, durable in antifriction performance, long lasting in anti-mold property, good in hygiene property and high in durability. When the rubber material is used as an automobile sealing strip material, the automobile sealing strip material has the advantages of being long in service life and good in sealing property.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high-durability anti-mildew automobile sealing strip rubber material 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 to impr...
