In addition, there are some rubber products are not very clear classification of raw materials, such as today's protagonists: natural rubber floor and composite natural rubber, two Those who are considered natural rubber, but with the standard natural rubber, rubber and other natural rubber smoke piece is different, and listen to Xiao Bian and we talk about the difference between natural rubber floor and composite natural rubber.
1, raw materials
It is literally understandable that its raw material is a plastic cup that falls on the rubber tree and is processed through complex processes. Its main components are the same as those of standard natural rubber, with more than 90% of rubbery hydrocarbons and A small amount of protein, fatty acids, sugar, ash, etc., in addition, the floor glue which also contains some wood chips, leaves; "compound natural rubber" is based on natural rubber plus the right amount of synthetic rubber and chemical additives mixing compound, The main ingredients are processed natural rubber 95-99.5%, a small amount of styrene-butadiene rubber, butadiene rubber, isoprene rubber and other general-purpose synthetic rubber, together with some stearic acid, zinc oxide, carbon black, peptizer etc. , Which is composed of two or more rubber compound.
2, performance and purpose
Natural and synthetic rubber floor have natural rubber properties, good elasticity, resistance to flexing, elongation at break, good low temperature flexibility and so on. The high-quality natural rubber and natural rubber standard indicators are almost the same, you can replace the production of natural rubber with a variety of high elasticity, high rubber content of rubber products, but the floor of natural rubber which contains some leaves, wood chips and other impurities, so Can only replace the production of natural rubber on the fineness of the less demanding molded rubber products, can significantly reduce the cost of raw materials. Composite natural rubber that has the basic properties of natural rubber, synthetic rubber and some performance, such as natural rubber and styrene-butadiene rubber compound, the wear resistance of the composite rubber is better than the wear resistance of pure natural rubber.
In actual production, many molded rubber products manufacturers use natural rubber instead of natural rubber to produce rubber products, so as to lower the cost of raw materials and increase the economic benefits.
