Can tire rubber be mixed with other materials?

Tire rubber can be mixed with other materials for various applications in tire manufacturing and material modification. The following is a detailed analysis of the mixing of tire rubber with other materials:

1、 Mixing of tire rubber and rubber powder

Application background: One of the main ways to recycle waste rubber is to process it into rubber powder and reuse it in the rubber and non rubber industries.

Mixing effect: The surface of rubber powder is uneven and has burrs, and it is relatively smooth when combined with rubber. It can be used in the processing of rubber products to improve the processing performance of blended materials (such as reducing deformation of semi-finished products and promoting exhaust). Low price tire rubber powder processed from waste tires can be blended with materials such as linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE) to prepare rubber products with better comprehensive performance.

matters needing attention:

In the tire rubber powder/linear low-density polyethylene blend system, the amount of tire rubber powder should be controlled within a certain range (such as around 5%) to ensure the performance of the blend material.

The smaller the particle size of the rubber powder, the better the filling effect in LLDPE material. It is usually recommended to use tire rubber powder with a fineness of around 100 to 120 mesh.

When blending tire rubber powder with high-density polyethylene, appropriate additives such as ethylene propylene diene monomer rubber, silicone oil, and DCP can be added to improve the impact strength and tear off productivity indicators of the rubber plastic blend material.

2、 Mixing of tire rubber and recycled rubber

Application background: In tire manufacturing, recycled rubber is sometimes used to reduce costs and maintain product quality.

Mixing effect: Recycled tire rubber has a low price and good compatibility with natural rubber, styrene butadiene rubber, butadiene rubber, etc. It can be used to produce bicycle tire tread rubber, etc. In actual production, black latex recycled rubber has physical and mechanical properties that are closer to natural rubber, and can directly replace natural rubber in the production of black bicycle tire tread rubber; White latex reclaimed rubber has the characteristics of good elasticity, high tensile strength, high elongation at break, and easy color matching, which can directly replace natural rubber in the production of colored bicycle tire tread rubber.

3、 Mixing of tire rubber with other rubber materials

Application background: In the tire manufacturing process, different rubber materials are selected for mixing according to the different uses and performance requirements of the tires.

Mixing principle: When selecting mixed rubber materials, multiple factors such as price, durability, and processability need to be considered.

Mixing effect: By mixing different rubber materials, tire rubber materials with specific properties can be obtained to meet the manufacturing needs of different tires.

4、 Precautions for mixed use

Mixing conditions: Mixing is the process of mixing different raw materials in a certain proportion to make rubber material. The parameters such as mixing time, temperature, and speed of the mixer need to be uniformly set to ensure uniform mixing.

Quality control: During the mixing process, it is necessary to strictly control the raw materials to ensure that there are no pollution or deterioration issues. At the same time, it is necessary to conduct quality testing on the mixed rubber material to ensure its stable quality.

Safety: Attention should be paid to safety during the mixing process to avoid safety accidents. At the same time, it is necessary to keep the machine clean to avoid contamination and uneven mixing.

In summary, tire rubber can be mixed with other materials and has broad application prospects in tire manufacturing and material modification. In practical applications, it is necessary to select suitable mixing materials and mixing processes based on specific needs and conditions.
