Floor natural rubber contains a small amount of internal leaves, sawdust and other impurities, with the same performance characteristics and natural rubber, so when used in the production of molded rubber products and indicators of the standard natural rubber are basically the same. However, natural rubber products also fall on the same natural rubber products, anti-aging, heat resistance, oil resistance, chemical resistance as special synthetic rubber, so this time need to be used with synthetic rubber to obtain better results.
1, landing with natural rubber and styrene-butadiene rubber and use
Styrene-butadiene rubber is the largest amount of general-purpose synthetic rubber, its physical structure, processing properties are similar with natural rubber, but styrene butadiene rubber heat-resistant, wear-resistant, anti-aging properties better than natural rubber, and natural rubber can be good Blend together, so when using natural rubber to produce rubber products can add the right amount of SBR. The main raw material on the market is the natural rubber tire + SBR + carbon black. Therefore, in order to improve the performance of natural rubber products landing, the same can also be used in rubber formulations with styrene-butadiene rubber.
2, landing natural rubber and isoprene rubber and use
Isoprene rubber is the most versatile rubber in general purpose elastomers and therefore is also referred to as "synthetic natural rubber" although the isoprene rubber has strength, tack, processability, tear strength, resistance Aging performance than natural rubber is low, but it has the natural rubber does not have the water resistance and insulation; Therefore, the use of floor rubber production of rubber products can be combined with isoprene rubber, rubber products to improve performance and extend the service life.
3, landing natural rubber and neoprene and use
Neoprene has good heat, oil, acid and alkali resistance, weather resistance, ozone and other performance characteristics, strong adhesion, but its poor cold resistance; natural rubber at low temperatures also have good flexibility and back elasticity. The use of an appropriate amount of neoprene in a floor finish can significantly improve the properties of the product, such as resistance to aging, ozone and flexing.
In addition to natural rubber floor can also be used with butadiene rubber, nitrile rubber and other rubber used, including: natural rubber products and use the right amount of butadiene rubber can be used to produce some of the requirements of flexibility, cold resistance, wear resistance of rubber products Such as automotive tires, rubber shoes, rubber sponge soles and other rubber products, which is because of butadiene rubber elasticity, cold resistance, wear resistance is particularly good; natural rubber can be used with nitrile rubber and improve rubber processing performance, cold resistance .
In the actual production, due to the price of various types of synthetic rubber is not low, so many rubber products manufacturers like to use natural rubber products in the floor and use latex reclaimed rubber, tire reclaimed rubber, isoprene reclaimed rubber and other products, can improve The comprehensive performance of rubber products, but also can significantly reduce the cost of raw materials.
