Application skills of superfine rubber powder in three typical products

The tire rubber powder processed from waste tires has a low price and can be added to various high, medium and low grade rubber products in the rubber product industry to reduce the cost of raw materials. The ultrafine tire rubber powder has higher fineness and more uniform dispersion in rubber products. It can improve the tear strength and fatigue resistance of the finished product; rubber soles, rubber tires and rubber water pipes are typical rubber products commonly used in life. Reasonable use of ultra-fine rubber powder can achieve a win-win situation between quality and cost; I would like to share with you the application skills of ultra-fine tire rubber powder in the above three rubber products.

Rubber sole

Under normal circumstances, the physical and mechanical properties of the rubber sole will decrease with the increase of the amount of rubber powder. The larger the particle size of the rubber powder, the faster the mechanical strength of the rubber sole will decrease. Relatively speaking, the particle size of the ultrafine tire rubber powder Small, can be evenly dispersed in the rubber compound, thereby reducing the negative impact of the rubber powder on the physical and mechanical properties of the vulcanized rubber, and reducing the raw material cost, improving the rubber sole tear strength and fatigue resistance while ensuring good mechanical strength of the rubber sole; For example, in the rubber midsole, more than 100 parts of ultra-fine rubber powder can be blended, and the cost of the rubber compound is significantly reduced under the premise of ensuring the performance of the rubber midsole.

2. Rubber tires

At present, the automobile is one of the most important means of transportation in life. Rubber tires naturally become a common rubber product. The quality of rubber tires directly affects the safety of driving. For rubber tires, the addition of appropriate amount of ultra-fine rubber powder can improve The tire's flex resistance, wear resistance, tear strength and tensile strength can also reduce part of the production cost; however, because the tire rubber powder will also bring "unfriendly" side to the performance of the car tire, When super-fine tire rubber powder is used in automobile tires, it is necessary to control the amount of rubber powder (about 10 parts), use ultra-fine activated rubber powder, and refine the rubber powder to eliminate the negative effect of tire rubber powder.

3. Rubber hose

The rubber pipe has low inorganic mechanical strength requirements. It can be used in rubber product formulations with a large amount of recycled rubber and recycled rubber powder products to reduce the cost of raw materials. In the actual production process, rubber water pipe processing enterprises use about 100 parts in the formula. Fine rubber powder can not only significantly reduce the cost, but also ensure the performance and service life of the rubber water pipe.

The biggest advantage of ultra-fine rubber powder is that it has high fineness and can be evenly mixed in the rubber compound. It will not have much influence on the physical and mechanical properties of rubber products, but not all ultra-fine rubber powder can be used in rubber products. The general load tire tread rubber powder has the best performance and can be used in medium and high grade rubber products, while some small tire ultrafine rubber powder and shoe rubber powder can only be filled in a high proportion of ordinary rubber products which have low requirements on mechanical strength. Such as rubber sheets, rubber miscellaneous pieces.
