rubber belt manufacturer's product advantage

Mar 11, 2019

Styrene-butadiene rubber is a kind of synthetic rubber with good performance. It has a wide application, but its tear strength is low, its dynamic flex resistance is poor, its resilience is lower than that of natural rubber, and it can be improved by using natural rubber. , butadiene rubber has the advantages of high elasticity, low hysteresis, low heat generation, low temperature resistance and wear resistance, but has poor tear resistance and poor wet skid resistance. The rubber produced is easy to collapse and lumps after aging. Natural rubber or styrene butadiene rubber can overcome these shortcomings.

 

Neoprene has excellent resistance to ozone cracking. Natural chloroprene rubber can significantly improve aging resistance. When producing anti-ozone cracked conveyor belt products, use ethylene propylene rubber, chlorinated polyethylene and natural rubber, styrene-butadiene. Rubber, nitrile rubber and neoprene can also be used together to obtain good results. Butyl rubber or chlorobutyl rubber has low gas permeability. It can be used as a beltless rubber surface when it is mixed with natural rubber and chlorobutyl rubber. The inner liner rubber, in the case where an oil-resistant rubber conveyor belt is required, a combination of chloroprene and natural rubber, butyric acid and natural rubber, butyl and polyethylene may be used;

 

Butadiene rubber has good performance, but the process performance is poor. It is easy to take off the roll and loose pocket during mixing. It can improve the process performance with natural rubber or styrene butadiene rubber. Butyl rubber or chlorobutyl rubber is used in rubber mixing. When there is frequent loose block phenomenon, the powder is very slow when adding carbon black, and the process performance of the rubber compound can be improved with a small amount of isoprene rubber. The neoprene rubber compound is easy to be scorched when pressed, and a small amount of low molecular weight polyethylene can be used. Effectively reduce the tendency of extrusion scorch, ethylene propylene rubber compound lacks viscosity, molding is difficult, and the use of ultra-speed vulcanized ethylene-propylene rubber and some natural rubber or phenolic resin can improve the adhesion of industrial thermal vulcanized rubber tape, styrene-butadiene The rubber compound shrinks greatly when it is pressed and pressed, the surface is rough, easy to foam, and the low-pressure polyethylene can reduce the shrinkage. When the butyl rubber is vulcanized with resin, although the active agent stannous chloride is used, the vulcanization speed is still compared. Slow, and with a small amount of neoprene or chlorosulfonated polyethylene, can replace stannous chloride, accelerate vulcanization, in the use of microwave continuous vulcanization process, for non-polar rubber, such as natural rubber Styrene-butadiene rubber, isoprene rubber, butadiene rubber and butyl rubber or the like, and polar rubber with the rubber conveyor belt to avoid less effective, warming slowly warm disadvantage that the rubber temperature reached quickly fast curing effect;
