The use of reclaimed rubber production of rubber products when the quality of reclaimed rubber products related to product quality, so choose a good reclaimed rubber products is essential. However, a qualified reclaimed rubber product not only needs high-quality raw materials, but also requires the cooperation of various additives, such as vulcanizing agents, accelerators, softeners, reinforcing agents and the like. There are many kinds of such additives, Xiao Bian first introduced several very common accessories it!
1, Sulfur: Sulfur is the most commonly used vulcanizing agent in the production and processing of reclaimed rubber. It can form a plastic mesh structure with the internal components of reclaimed rubber to enhance the elasticity of the rubber compound to increase the viscosity of the reclaimed rubber and suppress the blooming on the surface of rubber products. The reasonable addition of sulfur is of great significance to the performance of reclaimed rubber products, in which insoluble sulfur can effectively restrain the occurrence of reclaimed rubber blooming.
2, Carbon black: Carbon black is mainly used as reinforcing filler in reclaimed rubber products. It is the rubber compounding agent with the largest dosage in rubber products industry, which can improve the wear resistance and tear resistance of reclaimed rubber and improve the processing performance of reclaimed rubber. 2 parts of rubber can use 1 part of carbon black; However, in some light-colored, color recycled rubber products, usually can not use carbon black as the most reinforcing agent, replaced by white carbon black.
3, Antioxidant RD: Antioxidant RD is suitable for all kinds of latex reclaimed rubber products, reclaimed rubber products, butyl reclaimed rubber products, EPDM reclaimed rubber products and oil-resistant butyronitrile reclaimed rubber products, for heat and oxygen caused Aging protective effect of reclaimed rubber is excellent, is the tire, hose, tape, wire and cable sheathing the most commonly used antioxidant, it with a variety of reclaimed rubber compatibility is good, not easy to spit phenomenon, can effectively extend the reclaimed rubber products Service life.
4, paraffin: Paraffin is a colorless (or white or translucent), tasteless, odorless solid hydrocarbon mixture made from petroleum refining, with a crystalline structure, mainly used as reclaimed rubber antioxidant in reclaimed rubber products. Can be used as plasticizers and flame retardants, can improve the anti-aging properties of recycled rubber, increase product flexibility. Paraffin wax used in reclaimed rubber products are ordinary paraffin wax, microcrystalline wax and rubber protective wax.
5, Tar oil: Tar oil is an environment-friendly rubber oil can be used as a softening rubber to improve the flexibility, flexibility, ease of processing, easy mixing properties.
6, remove taste: fundamentally eliminate the odor and smell of recycled plastic products, when used according to the needs of products to add a reasonable dosage.
7, brightener: absorb the internal moisture of recycled plastic products, eliminate bubbles, improve the brightness of rubber products, plastic products to increase resilience.
Reclaimed rubber accessories are crucial in the production of reclaimed rubber products. Rubber product manufacturers must be cautious in selecting and matching them.
