The rubber sheet is a sheet-like product with a certain thickness and a large area produced after vulcanization of a rubber-based material, which has high hardness and general physical and mechanical properties. Therefore, ordinary plastic sheet products that work at normal temperature can be produced entirely using inexpensive reclaimed rubber. Among them, there are many manufacturers that use tire reclaimed rubber to produce black plastic sheets. Today, Xiaobian will share with you a rubber sheet formulation for reclaimed rubber production:
Recycled tire rubber, 200 parts; Paraffin, 7.5 parts; Accelerator DM, 1.0 part; Antioxidant, 0.5 parts; Zinc oxide, 2.5 parts; Sulfur, 2.5 parts; Calcium carbonate, 50 parts; Stearic acid, 0.5 parts; Total : 264.5 copies.
Formulation vulcanization conditions: 0.3 MPa (3.2 kgf/cm2) x 15 min; the produced tire reclaimed rubber sheet product has a tensile strength of 3.45 MPa (35.2 kgf/cm2), an elongation at break of 150%, and a hardness of 65.
Rubber sheet is a common rubber product in daily life. Different types of rubber materials are needed for different occasions. The tire reclaimed rubber can be used to produce ordinary plastic sheets with lower mechanical properties, which can not only significantly reduce the cost of raw materials, but also can meet the performance requirements of the plastic sheet. In addition, for some plastic sheets with special functions, other types of reclaimed rubber can also be used for production. For example, rubber sheets that work in the oil medium for a long time can be produced using nitrile reclaimed rubber; long-term exposure to outdoor sheets can be produced with EPDM reclaimed rubber that is excellent in high and low temperature performance; if your rubber sheet is Higher elasticity requirements can also be achieved using latex reclaimed rubber, where white latex reclaimed rubber is an ideal raw material for the production of light-colored colored rubber sheets, meeting the needs of different aesthetic groups.
As we all know, rubber rubber sheet has good elasticity, high comfort and strong abrasion resistance, but the production cost of using the original rubber is too high. It is difficult for manufacturers and users to accept the cost and price of the rubber sheet. The use of various types of reclaimed rubber to produce rubber sheets with corresponding performance requirements solves the problem of costly production of rubber sheets using raw rubber, and significantly reduces the cost of raw materials while ensuring that the sheets have equivalent performance.
