Natural rubber/synthetic rubber compound can be widely used in the production of tire tyres, rubber conveyor belts, cloth hoses, shock-absorbing products, etc. The products have higher comprehensive performance and longer service life. In actual production, not all synthetic rubbers mixed with natural rubber can achieve good blending effects. The combined effect of general synthetic rubber and natural rubber is better, such as butadiene rubber, styrene butadiene rubber, and isoprene rubber. .
1. The significance of the combined use of natural rubber and styrene butadiene rubber
Natural rubber and styrene-butadiene rubber are non-polar unsaturated rubbers. The vulcanization properties of the two are similar. The same vulcanization system can be used for vulcanization, and the combined effect is good. The combined use of natural rubber and styrene-butadiene rubber can further improve the wear resistance and aging resistance of natural rubber, and reduce the cost of raw materials.
2. The significance of the combined use of natural rubber and butadiene rubber
Butadiene rubber has excellent cold resistance, abrasion resistance and elasticity, and has less dynamic load heat generation. It can improve the abrasion resistance and low temperature resistance of natural rubber when mixed with natural rubber. This is particularly important in automobile rubber tires 2LLYY1125. In actual production, choosing natural rubber/butadiene rubber/styrene-butadiene rubber to produce rubber tires can better balance the relationship between wear resistance, traction and rolling resistance, and the physical and dynamic properties of the tire are better.
3. The significance of the combined use of natural rubber and isoprene rubber
Isoprene rubber is a kind of synthetic rubber closest to natural rubber. It is synthesized from isoprene and has better water resistance and electrical insulation than natural rubber. Its structure and performance are similar to those of natural rubber. It is called "synthetic natural rubber". Replace natural rubber to produce rubber tires and other products. The combined use of natural rubber and isoprene rubber can improve the water resistance, electrical insulation and chemical stability of natural rubber products. The strength, adhesion, processing performance, and fatigue resistance of isoprene rubber are slightly lower than natural rubber.
Natural rubber can be used together with styrene-butadiene rubber, butadiene rubber, or non-polar diene rubber such as natural rubber/styrene-butadiene rubber/isoprene rubber to manufacture automobile tires, rubber conveyor belts and other products with better comprehensive performance . In actual production, the types and amounts of synthetic rubber used in natural rubber products for different occasions can be determined by different manufacturers according to actual needs.
The combined use of natural rubber and general-purpose synthetic rubber can further improve the overall performance and service life of rubber products, and the combined use of low-cost synthetic rubber can also reduce the cost of raw materials. If manufacturers of natural rubber products want to reduce more production costs while improving the performance of their products, the editor recommends the use of natural rubber and suitable types of reclaimed rubber together. I have the opportunity to continue discussing the significance of using natural rubber and reclaimed rubber together. And skills.
