Tire releasing agent

Abstract

The invention discloses a tire releasing agent. The tire releasing agent comprises the following raw materials in parts by weight: 45 to 65 parts of polyorganosiloxane, 16 to 26 parts of phenoxyethanol, 20 to 28 parts of active nano calcium carbonate, 25 to 35 parts of acetylac etone, 28 to 40 parts of polyvinyl alcohol, 100 to 200 parts of deionized water, 5 to 10 parts of a cross-linking agent,1 to 10 parts of a catalyst, 25 to 50 parts of polybutylene terephthalate, 24 to 36 parts of vanadium(III) 2,4-pentanedionate, 42 to 60 parts of acetylac etone, 20 to 40 parts of triphenylphosphine and 5 to 10 parts of polyimide fiber. According to the tire releasing agent, nano calcium carbonate is compounded with an organic film-forming substance to prepare the novel rubber isolation releasing agent, the releasing agent is applicable for isolation among sizing materials and releasing of the sizing materials and molds in the tire production process, and the releasing agent is good in effect,convenient to use, free of pollution, safe and reliable. The phenomenon of product whitening caused by the fact that an inorganic powder releasing agent is singly used is overcome, the durability of the tire releasing agent is improved, the number of times of painting is reduced, and the surfaces of molds are protected.

Description

technical field [0001] The invention relates to a tire rubber auxiliary agent, in particular to a tire release agent. Background technique [0002] Tires are one of the important parts of the car. They are in direct contact with the road surface, and work together with the car suspension to ease the impact of the car while driving, ensuring that the car has good seating comfort and smooth driving; ensuring that the wheels and the road are in good condition The adhesion of the tire improves the traction, braking and passability of the car; bearing the weight of the car, the important role played by the tire on the car has attracted more and more attention. [0003] Rubber tire release agent is an important auxiliary agent in the production process of rubber tires, which can improve product appearance and performance, and improve product quality. Commonly used release agents include waxes, silicone oils, soaps, etc., each with its own characteristics; while the commonly use...

Problems solved by technology

Commonly used release agents include waxes, silicone oils, soaps, etc., each with its own characteristics; while the commonly used release agents are mainly inorganic powders such as talcum powder, etc., there are fatal defects of dust pollution and whitening of the product during use , it is necessary to develop an isolation release agent that overcomes the above defects and has both advantages
