Paraffin wax, also known as crystalline wax, is a hydrocarbon mixture extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils, usually a white, odorless, waxy solid that is a combination of reclaimed rubber production and Processing of the important additives. Reclaimed rubber to add the right amount of paraffin wax can improve the performance of rubber, rubber significantly improve the aging of the reclaimed rubber, rubber compound to increase flexibility.
Paraffin on the recycled rubber material has a certain lubricating effect, so reclaimed rubber products added paraffin can improve the rubber processing performance, the rubber easily rolled, extrusion and demoulding, improve the appearance of finished products.
Paraffin wax can also be used as a physical anti-ozone rubber regeneration agent, which is because in the production and processing of reclaimed rubber, wax migration from the interior to the surface of the formation of a layer of impermeable film barrier, it can prevent ozone and rubber Contact, a protective layer of recycled rubber material.
Paraffin wax products also have a kind of chlorinated paraffin, which in the production and processing of reclaimed rubber also plays an important role in adding different chlorinated paraffin wax different role: such as latex reclaimed rubber added 5-10 parts of chlorinated paraffin Can improve plasticity plasticity; butyl reclaimed rubber added chlorinated paraffin can improve the reclaimed rubber hardness, tear strength and elongation at break; paraffin can also improve the isoprene reclaimed rubber and EPDM reclaimed rubber Processing performance, improve flex resistance and tear strength of vulcanized rubber.
Ordinary paraffin wax, microcrystalline wax and rubber protective wax are used in the production of reclaimed rubber products. Ordinary paraffin is straight-chain paraffin, and the molecular chain is linear and structured. The protective film formed on the surface of reclaimed rubber products is less dense ; Most of the rubber protective wax and microcrystalline wax is isoparaffin, and the grains that migrate to the surface of the rubber compound after crystallization are smaller, and can be densely packed together to form a dense protective film. Different reclaimed rubber products choose paraffin wax according to the characteristics of the product itself, such as the tire force is more complex, the hose mainly by the flexion and expansion pressure, the cable is basically static, considering a variety of factors, the most suitable choice Paraffin varieties, improve the overall performance of recycled rubber products.
