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 mosquito-repellent insect-proofing automobile sealing strip rubber material. The mosquito-repellent insect-proofing automobile sealing strip rubber material is prepared from, by weight, 100 to 120 parts of EPDM, 40 to 60 parts of white carbon black, 0.5 to 1 part of diethyltoluamide, 0.1 to 0.15 part of prallethrin, 1 to 2 parts of cashew nut shell oil, 2 to 4 parts of zinc oxide, 1.5 to 2.5 parts of sulphur S80, 1.5 to 2.5 parts of anti-aging agent MB, 0.3 to 0.5 part of accelerant TMTD, 0.1 to 0.15 part of tea saponin, 3 to 5 parts of methyltrimethoxysilane, 0.5 to 1 part of tetrabutyl titanate, 0.15 to 0.25 part of titanate coupling agent NDZ-401, 6 to 8 parts of nano-graphite powder, 20 to 30 parts of castor oil. The mosquito-repellent insect-proofing automobile sealing strip rubber material possesses excellent wear resistance, long-lasting antifriction performance, and excellent mosquito-repellent insect-proofing effect, and is long in service life and excellent in sealing performance as an automobile sealing strip material.

Description

Technical field [0001] The invention relates to the technical field of rubber materials, in particular to a mosquito-repellent and insect-proof automobile sealing strip rubber material and a preparation method thereof. Background technique [0002] As an important polymer material that is indispensable in the national economy and daily life, rubber has excellent physical and mechanical properties, elasticity and processing properties. It has a role that other materials cannot replace in many important fields such as automobile transportation, mining, and chemical industry. . Tribological performance is a very important indicator of rubber materials, involving the wear resistance of rubber tire products and the wear resistance of seals. 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, and lubricants. [0003] At present, one of the more effect...
