Butyl recycled rubber has good air tightness, heat resistance, corrosion resistance and damping properties, and can be used alone or in combination with butyl rubber and EPDM rubber to produce shock-absorbing rubber products, effectively reducing the cost of raw materials under the premise of ensuring the shock absorption performance of the product. In actual production, which shock-absorbing rubber products can be mixed with butyl recycled rubber; What issues should be paid attention to when mixing shock-absorbing rubber products with butyl recycled rubber to reduce costs?
1. Which shock-absorbing rubber products can be mixed with butyl recycled rubber
Butyl recycled rubber has a wide range of applications in shock-absorbing rubber products, including automotive shock absorbing parts, industrial shock absorbing products, damping sound insulation materials, etc., and the specific applications are as follows.
(1) Automotive shock absorbing products: suspension systems and engine support parts such as automobiles and motorcycles, doors, engine covers and other parts, as well as automobile sound insulation materials and other parts can be mixed with butyl recycled rubber in an appropriate amount E5LYY124 reduce costs and vibration; (2) Industrial shock absorbing products: butyl recycled rubber can be used in conjunction with the original rubber to produce equipment foot mats, shock isolation blocks, sealing rings, sealing gaskets, cushioning gaskets, rubber springs and other shock-absorbing rubber products for shock absorption and anti-slip at the bottom of the equipment. (3) Rubber damping shock absorber and shock absorber film can be mixed with a large amount of butyl recycled adhesive to effectively reduce the cost of raw materials. (4) Other rubber shock absorbing products: rubber fenders/anti-collision strips can be mixed with butyl recycled rubber to absorb the collision energy during berthing.
2. Precautions for the production of shock-absorbing rubber products with butyl recycled rubber
(1) Pay attention to the proportion of butyl recycled rubber: when using butyl recycled rubber to reduce the production cost of shock absorbing rubber products, it is generally used in conjunction with butyl rubber, chloride butyl rubber or EPDM rubber, and the proportion of butyl recycled rubber in high-performance shock absorbing products is 20%-30%, and 40%-60% butyl recycled rubber can be mixed in industrial shock absorbing rubber products, and butyl recycled rubber can even be completely used in some sound insulation materials and shock absorbing gasket formulas.
(2) Pay attention to the damping performance of butyl recycled rubber shock absorber products: choose high structure and small particle size carbon black filling, adjust the vulcanization system, increase the cross-linking density, appropriately reduce the amount of softener, and improve the damping performance of butyl recycled rubber shock absorber products.
(3) Pay attention to the uniformity of butyl recycled rubber and raw rubber: when butyl recycled rubber and raw rubber are used together to produce shock-absorbing rubber products, butyl rubber needs to be molded first, and then when mixing the plasticized original rubber with recycled rubber, it is necessary to pay attention to the feeding sequence and discharge temperature; Strengthen the thinning or increase the number of triangular package turning, and use dispersion additives if necessary to make each component evenly dispersed.
(4) Pay attention to the moisture in the rubber material and compounding agent: strictly control the water content and volatile content of the original rubber, recycled rubber and compounding agent used in butyl recycled rubber shock absorbing products, and pay attention to the operation timing of vulcanization exhaust to avoid bubbles in shock absorbing products.
When using butyl recycled rubber to produce shock-absorbing rubber products, rubber product manufacturers must choose the right butyl recycled rubber, it is recommended to buy from a recycled rubber factory with a certain scale, the quality of recycled rubber is stable, and the inventory is sufficient. High-strength odorless butyl recycled rubber is processed from high-quality waste butyl inner tubes as raw materials, with strong air tightness, heat resistance, ozone resistance, aging resistance, shock absorption, high strength, good hand elasticity, environmental protection and odorlessness, etc., which can be used alone or in combination with butyl rubber to produce various shock-absorbing rubber products and reduce costs.
