Natural rubber is a rubber elastic solid made of latex in rubber trees as raw material, processed through solidification, drying and other processes, with good elasticity, high mechanical strength, small hysteresis loss, low temperature resistance, flex resistance and other performance characteristics, and is widely used in the production of tires, hoses, tapes, rubber shoes, adhesive tapes, and industrial products. However, the price of natural rubber on the market fluctuates greatly, so many rubber product manufacturers want to use low-priced and stable recycled rubber to replace some natural rubber, and the cost is easier to control.
1. Natural latex recycled glue
Natural latex recycled rubber is made of waste natural rubber, waste latex and its products as raw materials, processed by crushing, desulfurization, disinfection, drying, filtration and other processes, retaining the basic performance characteristics of natural rubber, high glue content latex recycled rubber has the characteristics of good elasticity, high strength, small specific gravity, large tear elongation, etc., and has good compatibility with natural rubber, which can directly replace all or part of natural rubber production products, effectively reducing the cost of raw materials.
Compared with natural rubber, latex recycled rubber also has the advantages of good plasticity fluidity, low power consumption, good vulcanization flatness, small vulcanization antigen and aging resistance.
2. Tire recycling glue
Tire recycled rubber is the waste tire rubber part after sorting, cutting, crushing, desulfurization, molding and other processes, so that it from an elastic state to a certain plastic and viscous, can be processed and re-vulcanized rubber, the main components are natural rubber, general synthetic rubber and carbon black, and the compatibility with natural rubber is good, which can replace some natural rubber production products, reduce the cost of raw materials while improving the performance of rubber processing technology and the comprehensive indicators of finished products.
For example, adding 5 parts of tire recycled rubber to car radial tires can appropriately improve the flex resistance and aging performance of the compound, and the high-speed performance and durability of the finished tire are good.
3. Synthetic rubber recycled rubber
There are many types of synthetic rubber recycled rubber, such as butyl recycled rubber, ethylene propylene recycled rubber, nitrile recycled rubber, styrene-butadiene recycled rubber, butadiene recycled rubber, chloroprene recycled rubber, etc., among which butyl recycled rubber, styrene-butadiene E5LYY318 recycled rubber, butylene butadiene recycled rubber, etc. can be mixed into natural rubber products in an appropriate amount to improve the processing technology and the performance of finished products, and reduce the cost of raw materials. For example, when natural rubber/styrene-butadiene rubber is used to produce rubber inner tubes, an appropriate amount of butyl recycled rubber can be used to improve the air tightness and tearing performance of the rubber under the premise of ensuring that the performance indicators of the rubber meet the standard requirements.
The high price and large price fluctuations of natural rubber make many downstream tires, shoe materials, seals, hose tapes and other manufacturers face the challenge of cost control; Recycled rubber retains the basic properties of rubber, with many types, good performance, stable price, and reasonable mixing of recycled rubber in natural rubber products, which can launch more high-quality and low-cost rubber products in the fierce market competition, effectively improving market competitiveness.
