Abstract

The invention discloses an environment-friendly impregnation system for fiber surface treatment, a preparation method and an impregnation method. The impregnation system comprises 100 parts of deionized water, 5-50 parts of maleic anhydride grafted polyolefin, 0.5-5 parts of a curing agent, 2-10 parts of blocked isocyanate and 50-200 parts of rubber latex. The raw materials adopted by the impregnation system are green and environment-friendly, and are industrial products, the preparation of an impregnation liquid and the fiber impregnation process are simple, and the process is short; and theisocyanate can enhance the activity of the fiber surface, and meanwhile, the maleic anhydride grafted polyolefin can be effectively co-vulcanized with the rubber latex, so that the formula system cangreatly improve the bonding effect between the fiber and the rubber, and can effectively replace an RFL impregnation system.

Description

technical field [0001] The invention belongs to the field of fiber impregnation, in particular relates to an environment-friendly impregnation system for fiber surface treatment, a preparation method and an impregnation method thereof, which are suitable for rubber skeleton materials. Background technique [0002] At present, fiber rubber composite materials are widely used in high-speed and high-load automobile / aircraft tires, high-pressure special rubber hoses and high-strength special rubber conveyor belts. According to statistics from the China Rubber Industry Association, the annual consumption of fiber skeleton materials in the rubber industry is nearly 3 million tons, of which synthetic fibers account for about 30% and increase year by year. However, because of its harsh service conditions, the adhesive performance of the fiber / rubber interface has become a key issue. In the rubber industry, the most commonly used bonding method for fibers and rubber is the resorcino...
