Butyl rubber reclaimed air tightness, good water tightness, and heat, corrosion resistance, aging resistance, shock absorption, insulation; The biggest advantage of natural rubber is good elasticity, high mechanical strength, but also has good insulation and flex resistance A lot of rubber products manufacturers in order to improve the processing technology of rubber products to improve the overall performance and reduce the cost of raw materials, the use of both butyl rubber and natural rubber combined with the way to produce their own products, butyl rubber and natural rubber production of inner tube is a good example of. So in different rubber products, butyl rubber and natural rubber regeneration What are the advantages? What other areas need attention?
Butyl reclaimed rubber retains the excellent gastightness, heat resistance and aging resistance of butyl rubber. Compared with butyl rubber, butyl reclaimed rubber also contains soluble rubber, insoluble gel, free sulfur, resin and waste Rubber vulcanization system of various additives such as sulfur, accelerators, so the molecular chain is small, the molecular size varies, the molecular polarity is high, and good compatibility with natural rubber. Butyl reclaimed rubber and natural rubber can significantly improve the mechanical properties and anti-aging properties of rubber products, prolong the service life of products.
When butyl rubber and natural rubber are used in combination with rubber products, usually 30 parts of butyl rubber and 70 parts of natural rubber rubber can obviously improve the comprehensive use performance of rubber products, good fluidity and excellent processing performance, and improve the rubber products Processing performance; Therefore, manufacturers can be based on this based on the various performance requirements of rubber products to adjust the ratio of butyl rubber reclaimed rubber and natural rubber.
In the choice of butyl rubber and natural rubber filling system, you can use carbon black and clay as filler filling system, because the carbon black can increase the hardness and modulus of the compound rubber set stress, while the rubber compound Tensile strength has little effect, but the amount of carbon black should not be too much, otherwise it will lead to butyl rubber reclaimed rubber and natural rubber compound elongation at break significantly reduced. The use of clay in combination with butyl reclaimed and natural gums minimizes costs without sacrificing the physical properties of butyl reclaimed and natural rubber blends.
Some rubber products on the adhesive viscosity demanding, this time can use 2402 resin as a thickening aids, basically does not reduce the butyl rubber and natural rubber compound with the physical properties and can also improve the rubber compound Self-adhesive.
The use of butyl rubber reclaimed rubber and natural rubber used in conjunction with the production of rubber products, butyl rubber reclaimed their own elongation at break of the phenomenon can be significantly improved, so the natural rubber elongation at break particularly high; Sexual, anti-aging properties and other aspects of the lack of, and butyl rubber reclamation can improve these weaknesses. Rational use of butyl rubber and natural rubber reclaim, to improve the butyl rubber reclaimed rubber as the main raw material or natural rubber as the main raw material of the comprehensive use of rubber products of great significance.
