Abstract

The invention relates to a preparation method for a novel rubber strip for sealing of automobile doors and windows and a product. The preparation method employs ethylene propylene diene monomers as basic materials with cooperation of certain amounts of carbon black, calcium carbonate, paraffin oil, zinc oxide, stearic acid, polyvinyl alcohol, high-molecular wax, compound antioxidants, dispersants, compound accelerants, vulcanizing agents, fire retardants and the like. The above materials are subjected to mixing, open milling and vulcanization technologies to obtain the rubber strip. The preparation method has advantages of simple formula, simple production technology, short vulcanizing time, high production efficiency, relatively low production cost, easy industrialization enforcement and the like. The rubber product for sealing is advantaged by good sealing performance, uniform structure, resistance to corrosion, resistance to high and low temperature, flame resistance, environment protection and comfort.

Description

technical field [0001] The invention relates to the field of rubber sealing materials, in particular to a preparation method and a product thereof of a novel rubber strip for automobile door and window sealing, which has good sealing performance, uniform structure, corrosion resistance, high and low temperature resistance, flame retardancy and environmental protection. Background technique [0002] In the modern industrial field, sealing technology plays a pivotal role, and sealing failure will not only greatly increase subsequent maintenance costs, but may also lead to fatal disasters. Material properties are the decisive factors for the performance of sealing products. In the field of automobiles, sealing materials are mainly used in three aspects: oil seals, water seals and air seals. Among them, automobile door and window sealing strips are important air seal and water seal components. They are widely used in car doors, windows, skylights and other parts. They have sound...
