Rubber powder is a rubber particle obtained by mechanical crushing or chemical treatment of waste rubber (such as waste automobile tires), which has unique physical and chemical properties and is an important rubber and plastic elastomer material in the rubber and plastics industry. Polyethylene is a thermoplastic resin prepared by polymerization of ethylene monomer. Rubber powder has good elasticity, wear resistance and aging resistance, and is more and more widely used in polyethylene (PE) resin.
1. The role of rubber powder in polyethylene resin
(1) Enhance compatibility
Adhesive powders can be improved through surface modifications, such as plasma treatment, corona treatment, or electron beam radiation, to improve their compatibility with polyethylene resins. These treatments can enhance the interaction among the powder and the polyethylene resin by introducing polar groups or increasing surface roughness on the surface of the powder.
(2) Improve the mechanical properties of polyethylene
The addition of rubber powder can significantly improve the mechanical properties of polyethylene resin, such as impact strength and tensile strength. For example, the compatibility and impact resistance of polyethylene/rubber powder blends can be improved by adding waste rubber powder coated with functional polymers.
Experiments have shown that the impact strength of the blend can be increased by about 40%-60% after the addition of rubber powder.
(3) Improve the processing performance of polyethylene
The addition of rubber powder can also improve the processability of polyethylene resins. The fine particles of the rubber powder can be used as a lubricant to reduce friction during processing, thereby improving processing efficiency and product quality.
2. Practical application of tire rubber powder in polyethylene
Rubber powder is used for polyethylene resin modification, which can effectively improve the mechanical properties and processing properties of plastics, and prepare plastic materials with excellent impact resistance, which are widely used in automobiles, home appliances and other fields.
(1) Rubber powder and polyethylene resin can be blended to prepare rubber and plastic elastomers and improve the elasticity and wear resistance of materials. By adjusting the addition amount and treatment method of rubber powder, rubber and plastic elastomers with different properties can be prepared to meet the needs of different application scenarios.
(2) In tire manufacturing, rubber powder can be used as a reinforcing agent to improve the wear resistance and anti-aging performance of tires. By blending with polyethylene resin, it is possible to prepare tire tread compound with excellent performance and extend the service life of tires.
The rational use of rubber powder in polyethylene resin, through surface modification technology, the compatibility of rubber powder and polyethylene is enhanced, which not only improves the mechanical properties of the blend, such as impact strength and tensile strength, but also improves the processing performance E4LYY56, making the production process more efficient. The addition of rubber powder brings better wear resistance and anti-aging properties to polyethylene resin, which is especially important in key areas such as tire manufacturing.
