Application skills of rubber powder in motorcycle tread rubber

Rubber powder is one of the main ways of recycling waste rubber and waste rubber products, mainly based on waste tire rubber powder; in motorcycle tire tread rubber produced from natural rubber, cis-butyl rubber and styrene-butadiene rubber. The use of appropriate amount of tire rubber powder can effectively reduce the production cost; usually the tire powder with different surface activity has different effects on the physical properties of motorcycle tread rubber, so its usage and dosage are very different; then it is commonly used in motorcycle tread rubber. There are several types of tire rubber powders, and how does it affect the performance of the tread rubber? What is the specific amount of control?

Studies have shown that ordinary tire rubber powder, activated rubber powder and activated modified rubber powder can be blended in motorcycle tread rubber, which can improve the wear resistance of tread rubber while reducing the cost (for motorcycle tread rubber) In terms of wear resistance, it is the main factor affecting its performance and life. The specific effects and dosages of different types of rubber powder on motorcycle tread rubber performance are as follows:

1. Effect of rubber powder on various performance indexes of motorcycle tread rubber

Under normal circumstances, the tire rubber powder mixed in the tire tread rubber of motorcycle tires is controlled within a certain range, which basically does not affect the puncture resistance, aging resistance, tear resistance and wear resistance of the tire tread rubber. Consumption and grip, wherein the application effect of activated rubber powder and modified activated rubber powder in motorcycle tread rubber is better than ordinary rubber powder, and the performance and physical machinery of tire tread rubber with modified activated rubber powder Better performance; mixing appropriate amount of activated rubber powder or modified activated rubber powder in motorcycle tire tread rubber can not only maintain the wear resistance of tread collagen, but also improve the mileage of motorcycle tires.

2. The specific amount of three kinds of tire rubber powder in the formula of motorcycle tread rubber

Since the activated rubber powder and the modified activated rubber powder have high surface reactivity, the blending effect of the natural rubber/cis-butadiene rubber/styrene-butadiene rubber is better, so the amount can be appropriately increased. Generally, the amount of ordinary rubber powder in the tire tread rubber formula of motorcycle tire is about 5-10 parts. The fine tire rubber powder and ultrafine tire rubber powder in the ordinary rubber powder have large contact area with rubber molecules and higher surface activity. The dosage can be increased appropriately; the dosage of activated rubber powder can be increased to 25-50 parts; the amount of modified activated rubber powder is more, controlled between 30-50 parts; motorcycle tire manufacturers need to be reasonably determined according to the surface characteristics of rubber powder. The amount of rubber powder in motorcycle tread rubber.

3. How to choose the waste tire rubber powder used in the motorcycle tread rubber formula

With the continuous development of waste rubber processing technology, tire rubber powder has developed from ordinary rubber powder into fine and superfine tire rubber powder, and then developed into activated rubber powder and modified activated rubber powder. Different manufacturers and different equipments are produced on the market. The quality of the rubber powder is uneven, so the application effect in the motorcycle tread rubber is very different; when selecting the tire rubber powder, the manufacturer must cooperate with the regular rubber powder manufacturer as much as possible to select the large tire tread processing. The high-quality rubber powder can greatly improve the wear resistance of motorcycle tread rubber while reducing the cost.
