Natural rubber has high mechanical strength, good resilience and moderate elastic modulus, which is an ideal raw material for the production of ordinary rubber V-belts. However, the price volatility and poor supply stability of the natural rubber market have brought cost control problems to rubber products enterprises. Choosing the right low-cost rubber raw material can not only effectively control costs, but also maintain the quality and performance of products. What low-cost rubber raw materials can be used in the production of rubber V-belts with natural rubber as the main raw material? What are the advantages?
1. Sub-brand landing natural rubber
Sub-brand landed natural rubber refers to a by-product formed by separating the natural rubber with lower yield and slightly worse quality through screening and classification in the process of natural rubber processing. Compared with natural rubber, the quality and performance of sub-brand landing natural rubber may be slightly different, but it has the basic performance characteristics of natural rubber, which can replace some genuine natural rubber to produce ordinary V-belts, effectively reducing the cost of rubber.
2. Recycled rubber
Recycled rubber is a physical and chemical process such as crushing, heating, mechanical and chemical treatment of waste vulcanized rubber, so that it can be processed and vulcanized from an elastic state into a certain plasticity and viscosity, which can be processed and vulcanized. Latex reclaimed rubber, tire reclaimed rubber and natural rubber have good compatibility, which can replace part of natural rubber to produce ordinary rubber V-belts, effectively reducing the cost of raw materials.
3. Styrene-butadiene rubber
Styrene-butadiene rubber is polymerized from styrene and butadiene, which has the characteristics of good wear resistance, high strength and elasticity, good aging resistance and easy processing. The price of styrene-butadiene rubber is lower and more stable than that of natural rubber, and when used in combination with natural rubber, it can effectively improve the wear resistance of the rubber compound and reduce the surface loss of the rubber V-belt caused by friction. If you want to further reduce the cost of ordinary V-belts of natural rubber, you can also choose oil-filled styrene-butadiene rubber or sub-brand styrene-butadiene rubber.
4. Butadiene rubber
Cis-butadiene rubber is polymerized from butadiene, with a cis structure content of more than 95%, excellent elasticity, wear resistance, flex resistance and low temperature resistance, small hysteresis damage, and low dynamic heat generation. The molecular chain of butadiene rubber has good flexibility and strong wetting ability, which can be filled with more reinforcing fillers and operating oil than natural rubber and styrene-butadiene rubber, and can be used with natural rubber and styrene-butadiene rubber to produce rubber V-belts to reduce the cost of rubber materials.
When using low-cost rubber raw materials instead of natural rubber to produce ordinary V-belts, rubber product manufacturers not only need to consider the cost factor, but also need to comprehensively evaluate the physical and chemical properties of the rubber compound E4LYY923 whether they can meet the requirements of V-belts. In actual production, the performance requirements of different rubber layers of ordinary rubber V-belts are different, and the addition ratio and formula of low-cost rubber raw materials are different. In the future, Xiaobian will share with you the vulcanization formula and formula design points of ordinary rubber V-belt mixed with low-cost rubber raw materials.
