Reclaimed rubber has a wide range of raw materials, low product prices, and good production process performance. It can replace high-priced raw rubber in the rubber and non-rubber industries to reduce costs. In the rubber industry, reclaimed rubber can replace natural rubber and various synthetic rubbers for the production of tires, hoses, tapes, rubber sheets, cushions, etc.; in the non-rubber industry, it is also used to manufacture linoleum, waterproof membranes, and sealant putties. Ideal raw material for building materials.

1. Tire tread rubber

Tread reclaimed rubber processed with tire tread rubber powder as raw material has high mechanical strength and good elasticity, and can be recycled into various tire tread compounds. In actual production, the tire tread compound produced by using natural rubber/butadiene rubber in a ratio of 70/30 can be mixed with about 10 parts of reclaimed tread rubber, and the tensile strength of the rubber compound can reach more than 21MPa; when natural rubber/ When the combined ratio of butadiene rubber is 45/55, about 15 parts of tread reclaimed rubber can be mixed, and the tensile strength of the rubber material is 19-20MPa.

Butyl reclaimed rubber can also be used in tire tread rubber. When the combined ratio of natural rubber/butadiene rubber is 60/40, 20 parts of tread reclaimed rubber and 10 parts of butyl reclaimed rubber can be mixed, and the finished product is stretched. The tensile strength can reach more than 21MPa.

2. Bicycle tread rubber

When using natural rubber, butadiene rubber and styrene butadiene rubber to produce bicycle tread rubber, about 80-100 parts of reclaimed tread rubber can be blended, and the tensile strength of vulcanized rubber can reach 18MPa or more; blending 40- With 50 parts of reclaimed tread rubber, the tensile strength of the finished bicycle tread rubber can reach 20MPa.

3. Embedding thread suction hose

The suction hose is composed of an inner rubber layer, a rubber cloth layer, a metal spiral winding layer and an outer rubber layer. The suction hose with the metal spiral embedded in the tube structure is the buried thread suction hose. In actual production, the inner layer, middle layer and outer layer of the buried thread suction hose can be mixed with a large amount of reclaimed rubber, effectively reducing the cost of raw materials. Theoretically, 100 parts of natural rubber can be mixed with 100 parts or more of reclaimed rubber to prepare the middle layer rubber and inner layer rubber of the suction hose. The variety and amount of reclaimed rubber in different embedding hoses are not the same.

4. Rubber sole

Rubber sole has the characteristics of good resilience, high softness and excellent shock absorption effect, which is deeply loved by all people. The sole compound is an application field where more reclaimed rubber is mixed. In actual production, rubber shoe foam midsoles, hard midsoles, black outsoles, all butadiene rubber foam bottoms, inner heels, etc. can be mixed with a large amount of reclaimed rubber to effectively reduce the cost of raw materials. Among them, light-colored and colored rubber soles are recommended to use white latex reclaimed rubber and colored latex reclaimed rubber, and black soles use tire reclaimed rubber or rubber shoe reclaimed rubber.

In the production of rubber products, reclaimed rubber can play multiple functions such as improving the performance of rubber materials, reducing raw material costs, and saving labor and electricity costs. The rational use of reclaimed rubber can achieve a win-win situation in quality and cost; expand the use of reclaimed rubber in the rubber industry The application field can solve more waste rubber pollution environmental problems and improve the economic benefits of manufacturers.

Reclaimed rubber is not only widely used in automobile and bicycle tire tread compounds, hoses, and shoe soles, but also in the production of rubber sheets, rubber inner tubes and waterproof materials, which can effectively reduce the cost of raw materials. In actual production, 2YLYY803 tire reclaimed rubber, latex reclaimed rubber, butyl reclaimed rubber, nitrile reclaimed rubber and EPDM reclaimed rubber can all play an important role in the rubber and non-rubber industries.

5. Rubber sheet

Rubber sheet is a sheet-like rubber product with a certain thickness and a large area, which is made of rubber as the main material and vulcanized with various compounding agents. It is widely used in industrial and mining enterprises, transportation, house ground and other occasions. . In actual production, tire reclaimed rubber can be used in large quantities in ordinary industrial rubber sheets. Nitrile reclaimed rubber is recommended for oil-resistant rubber sheets and wear-resistant rubber sheets. White and colored latex reclaimed rubber can be used for colored rubber sheets, and acid and alkali resistant rubber sheets can be used Use butyl reclaimed rubber in an appropriate amount.

6. Hard rubber

Hard rubber is rubber that can hardly be stretched above room temperature. It is a black hard substance at room temperature. It is generally made by adding a large amount of sulfur to natural rubber or synthetic rubber and vulcanizing it for a long time. Battery rubber shells, rubber tanks, etc. are common hard rubber products, which can be mixed with a large amount of reclaimed rubber. In actual production, 100 parts of natural rubber can be added with 100-200 parts of tire reclaimed rubber, and 100 parts of styrene butadiene rubber can be used with 200-300 parts of tire reclaimed rubber to prepare a battery tank. In the hard rubber, lower-priced reclaimed footwear rubber can also be used.

7. Butyl inner tube

Compared with natural rubber inner tubes, butyl rubber inner tubes have better air-tightness, high temperature resistance, aging resistance and longer service life. In actual production, butyl reclaimed rubber can be used with butyl rubber to produce cost-effective inner tube products, or butyl rubber/ethylene propylene rubber/butyl reclaimed rubber can be used together to improve rubber processing performance and reduce costs.

8. Waterproof membrane

The waterproofing membrane made of reclaimed rubber as the main raw material has the characteristics of low cost and simple production process, which can meet general waterproof requirements. Reclaimed rubber can be used alone, or reclaimed rubber and petroleum asphalt can be used as the base material. It is processed by batching, mixing, calendering, trimming, coiling and other processes.

9. Rubber and plastic blending: reclaimed rubber can be blended with thermoplastic resins, using dynamic vulcanization, static vulcanization, rubber-plastic blending and other non-vulcanization situations, or using reclaimed rubber modified thermoplastic resin to make foamed rubber The product has the characteristics of good elasticity and small compression deformation.

10. Composite with fiber: Reclaimed rubber can also be composited with waste fiber materials for injection and basic molding of various products.

With the continuous improvement of the production process of reclaimed rubber, the application range of reclaimed rubber in the rubber and non-rubber industries has become wider and wider. It is used in tires, hoses, conveyor belts, shoe materials, adhesives, process rubber, sports equipment, Sealing strips, sealing rings, shock-absorbing products, waterproof materials and other fields are widely used. Later editors have the opportunity to continue to share with you the application of reclaimed rubber in other fields.
