When using recycled rubber to reduce costs for black rubber products with high mechanical strength requirements produced by natural rubber and styrene-butadiene rubber as the main raw materials, high-strength tire recycled rubber or black latex recycled rubber is mostly selected. The two recycled rubber raw materials are different and the price is different, under the premise of consistent tensile strength, which one is more suitable to choose? What is the difference among high-strength tire recycled rubber and black latex recycled rubber? What black rubber products can be used in the production?
1. Performance characteristics of high-strength tire recycled rubber and black latex recycled rubber
High-strength tire recycled rubber is generally made of 900-1200 waste tire tread rubber powder as raw material through crushing, desulfurization, refining and other processes, and has the characteristics of high strength, wear resistance, tear resistance, E5LYY74 and other characteristics. Black natural latex recycled rubber is generally made of variegated waste natural glue, waste latex and its products as raw materials through crushing, desulfurization, disinfection, drying and other processes, with high effective rubber hydrocarbon content, good feel elasticity, high tearing elongation, small specific gravity and other performance characteristics.
2. Use of high-strength tire recycled rubber and black latex recycled rubber
Under the same tensile strength, high-strength tire recycled rubber has good wear resistance, low resilience, and low price, and is suitable for producing black rubber products with large dynamic loads, such as tires, conveyor belts, and shock absorbers. Black latex recycled rubber has good resilience and high tear elongation, and is suitable for the production of black rubber products with higher requirements for elasticity, flexibility or comfort, such as rubber soles, flexible hoses, sealing strips, low-hardness gaskets, etc.
Under the same tensile strength, most industrial rubber products with natural rubber as the main raw material choose recycled rubber, tire recycled rubber is more cost-effective; When there are higher requirements for elasticity, resilience, odor, and environmental protection, it is recommended to use latex recycled rubber. In actual production, high-strength tire recycled rubber can also be used in conjunction with black latex recycled rubber, the former provides strength and wear resistance, and the latter provides tear elongation and flex resistance, with both performance and cost.
High-strength recycled rubber B selects 1200 waste tire top by the rubber washer to brush and crush the impurities through magnetic separation and vibrating screen to remove impurities, using Belgian equipment and advanced high-strength segmented desulfurization process production, the fineness reaches more than 40 mesh, with high strength, good elasticity, small specific gravity, no migration, low Mooney viscosity, easy to operate, etc., no need to plasticize, the refining process is simple, after thousands of enterprises are used to ensure the cost of product quality on the basis of reducing the cost by about 23%, It is an ideal raw material for partially replacing natural rubber to produce black high-strength rubber products or black high-wear rubber products.
