Ways to reduce the cost of raw materials for tire pads.

Author:


The tire cushion belt is an annular belt processed from rubber as the main raw material. Its main function is to protect the inner tire contact surface from rim wear. In actual production, the tire cushion belt is generally made of natural rubber, styrene-butadiene rubber or butadiene rubber as the main raw material, and the use of non-reinforcing fillers such as calcium carbonate can reduce the cost of raw rubber. Due to the performance limitation of rubber filler in the application of rubber products, a large amount of filler is not an ideal way to reduce the raw material cost of tire cushion belt, and how to reduce the cost of cushion belt?

 

 

1. Add recycled rubber

The tire cushion belt has high requirements for flex resistance, aging resistance, and tear resistance, and requires good tensile strength and small compression permanent deformation. When natural rubber, styrene-butadiene rubber and butadiene rubber are HYL21Y5Y2Y to produce automobile tire cushion belts, reclaimed rubber can be used in an appropriate amount. Among them, the tire reclaimed rubber processed from waste tires has low price and good compatibility with the above rubber, which can meet the basic performance requirements of cushion belt rubber and effectively reduce the cost of raw materials.

In actual production, tire tread reclaimed rubber has high strength, good elasticity, flex resistance and tear resistance, and is more suitable for tire cushion belt production.

 

 

2. Add recycled rubber powder

Recycled rubber powder can be used as the main raw material in the production of rubber products, and can also be added to the production of rubber products as a filler. After adding an appropriate amount of recycled rubber powder to the tire cushion belt, appropriately reduce the amount of carbon black, add a small amount of flow agent and tackifier, can reduce the cost of raw materials and improve the softness of the cushion belt under the premise of ensuring the physical requirements of the cushion belt. In actual production, 60-80 purpose tire rubber powder blending effect is good, can effectively reduce the cost.

3. Reclaimed rubber rubber powder

 

 

In the production of tire cushion belt, reclaimed rubber and reclaimed rubber powder can also be used together to reduce the cost of raw materials. In actual production, a small amount of butadiene rubber can be added to reduce the cost when using reclaimed rubber/rubber powder with natural rubber and styrene-butadiene rubber as raw materials to further improve the flex resistance of the rubber material. It is recommended to choose sulfur vulcanization system, with high wear-resistant carbon black and amine antioxidant to improve the mechanical strength and aging resistance of the tire cushion belt. An appropriate amount of inorganic filler was increased to improve the heat resistance of the compound and reduce the cost.

To reduce the production cost of tire cushion belt, rubber product manufacturers can not only use reclaimed rubber or reclaimed rubber powder alone, but also use reclaimed rubber and rubber powder together, and some products can also use all rubber renewable resources.
