Sponge rubber sheet is a vulcanized rubber sheet with a porous structure, which has the characteristics of low density, high elasticity, heat insulation, sound insulation, sound absorption and cushioning. Ordinary sponge rubber plate is mainly used in general industrial and civil fields, and does not have high requirements for special properties such as oil resistance and heat resistance, but it needs to have good elasticity, flexibility and processing performance, and is generally processed with natural rubber, styrene-butadiene rubber and other main raw materials. In the production of ordinary sponge rubber sheets, the following kinds of reclaimed rubber are ideal options to reduce costs.
(1) Natural latex reclaimed rubber
Natural latex reclaimed rubber is a reclaimed rubber made of waste natural rubber products through crushing, desulfurization, refining and other processes, which has good elasticity and processing properties. Its main composition is similar to that of natural rubber, so it can be used as a substitute for part of natural rubber in ordinary sponge rubber sheets. In the formula design, the combination of natural rubber reclaimed rubber and natural rubber can effectively reduce the production cost while maintaining the basic properties of the sponge rubber plate.
(2) Tire reclaimed rubber
Tire reclaimed rubber is processed from waste tires, its raw material sources are wide and the price is low, the main components include natural rubber, synthetic rubber and carbon black, and natural rubber, styrene-butadiene rubber, etc. have good compatibility, can meet the process requirements and physical and mechanical properties of sponge rubber plate production, the price is much lower than the original rubber, generally with natural rubber, butadiene benzene rubber and used together to produce ordinary sponge rubber plate, replacing 30%-50% of natural rubber, some products can be completely used tire reclaimed rubber, maintain good elasticity, Softness and processability.
(3) Styrene-butadiene reclaimed rubber
Styrene-butadiene reclaimed rubber is processed from waste styrene-butadiene rubber products, which has good wear resistance and processing performance. Styrene-butadiene reclaimed rubber can be used to replace part of styrene-butadiene rubber or natural rubber in ordinary sponge rubber sheets, which can significantly reduce the cost of raw materials and have little impact on the elasticity, flexibility and other properties of sponge rubber sheets.
The performance requirements of sponge rubber sheets in different use occasions are different, and rubber plate manufacturers can choose the appropriate reclaimed rubber according to the actual needs to reduce the cost of raw materials on the premise of ensuring product quality. When using reclaimed rubber to reduce the production cost of ordinary sponge rubber E4LYY627 board, a reasonable design formula can further improve the processing performance and physical properties of the sponge rubber sheet while reducing the cost, so as to meet the market demand for cost-effective sponge rubber. Follow-up to share with you latex reclaimed rubber, styrene-butadiene reclaimed rubber, tire reclaimed rubber to produce sponge rubber plate vulcanization formula.
