The butyl reclaimed rubber on the market includes a butyl reclaimed rubber processed from a butyl inner tube and a chlorinated butyl regenerated rubber obtained from a waste medical butyl cork stopper, wherein the chlorinated butyl reclaimed rubber is Other types of unsaturated rubber have better compatibility than butyl inner tube reclaimed rubber. They can be used together with natural rubber, neoprene rubber, styrene-butadiene rubber and butadiene rubber to produce various rubber products with special performance requirements. Low glue can further reduce the cost of raw materials and improve the properties of butyl rubber products.
1, chlorinated butyl reclaimed rubber and natural rubber, styrene-butadiene rubber, tire reclaimed rubber and used to produce grass tires.
The main raw materials of traditional grass tires are natural rubber and styrene-butadiene rubber, and moderate amounts of highly wear-resistant carbon black and calcium carbonate. In terms of rubber raw material costs, the prices of natural rubber and styrene-butadiene rubber are high, especially natural rubber. The price is subject to large fluctuations, and the cost is not well controlled; rubber product manufacturers use a small amount of tire reclaimed rubber in the formula of the grass tire; after that, adding a suitable amount of chlorinated butyl reclaimed rubber to the grass tire can increase the application of tire reclaimed rubber in the formula. The ratio further reduces the cost of rubber raw materials, and can improve the fluidity of the lawn tire mix, and improve the heat resistance and aging resistance of finished grass tires on the premise that the grass tire tires are qualified.
2. Chlorinated butyl reclaimed rubber and butyl rubber used to produce shock-absorbing rubber products
Vibration-absorbing rubber products are used to eliminate or reduce the transmission of mechanical vibration, to achieve shock absorption, sound absorption, and reduce the impact of the impact of a class of rubber products, in the shock absorption, housing, vehicles, machinery, electronic equipment industry has a wide range of applications. In addition to excellent airtightness, butyl rubber also has good damping, shock absorption and electrical insulation properties. It is an ideal raw material for the production of shock-absorbing rubber products, especially for various electronic instruments in the electronics industry. . The combination of chlorinated butyl reclaimed rubber and butyl rubber to produce shock-absorbing rubber products in various electronic instruments and meters can not only improve the plasticizing process and processability of the compound, but also can significantly reduce the cost of raw materials. It should be noted that when using butyl rubber and chlorinated butyl reclaimed rubber in combination with the production of electronic shock absorbing products, it is best to choose a chlorinated butyl reclaimed rubber with a fineness of more than 60 mesh.
3, chlorinated butyl reclaimed rubber and butyl rubber or natural rubber and use productivity inner tube
At present, the inner tubes on the market are basically butyl inner tubes. The traditional natural rubber inner tube has been replaced by butyl inner tubes; the inner tube of motorcycles, such as motorcycle inner tubes, is hermetic, elastic, and resistant to flexion and tearing. Cracking, high temperature resistance, anti-permanent compression deformation requirements are high, butyl rubber has undoubtedly become the first choice of raw materials; but butyl rubber itself is too low degree of unsaturation, curing speed is slow, affecting the production efficiency of car inner tube, increase production The cost; the market price of the inner tube product of the train is not very high, so it is very necessary to take certain measures to reduce the raw material cost of the inner tube of the train and increase the production efficiency. Chlorinated butyl regenerated rubber has all the performance characteristics of butyl rubber. The vulcanization speed and the co-vulcanizing properties with other rubbers are superior to those of butyl rubber. The heat resistance and compression set resistance are better, and the price is lower than that of butyl rubber. Half the price, so can be combined with butyl rubber inner tube; at the same time, chlorinated butyl reclaimed rubber can also be used in combination with natural rubber at a higher blending ratio to produce an inner tube with excellent airtightness.
The application of chlorinated butyl reclaimed rubber in the rubber product industry can not only stop here, but can also be used in the curing of hydrostatic tires, capsules, etc. In the production of non-vulcanized rubber products such as wire and cable, protective articles, heat-resistant conveyor belts, steam hoses, and other vulcanized rubber products such as putty rubber and damping sheets, the cost of raw materials is significantly reduced.
