The role of commonly used organic reinforcing agents in recycled rubber products 2

The organic reinforcing filler can not only improve the reinforcing performance of the rubber product in the production of rubber products, but also reduce the volume cost of the product. Xiaobian remembers that the rubber reinforcing organic filler used in Baidu Encyclopedia also includes rubber powder and reclaimed rubber. Recycled rubber produced from waste rubber and waste rubber products can be used as a main material instead of fillers in rubber products. When using recycled rubber to produce rubber products, the most important role of organic reinforcing agents is not to reduce costs, but to improve performance.

3. The role of high styrene resin in recycled rubber products

High styrene resin is an emulsion copolymer of styrene and butadiene. The high styrene resin commonly used in the rubber product industry generally has a styrene content of more than 85%, low density, high hardness and excellent impact resistance. When using recycled rubber to produce rubber products, high styrene resin can significantly increase the hardness of rubber compound and improve the flexural strength and tear strength of recycled rubber products. It is an organic supplement commonly used in the production of reclaimed rubber soles, hard sponge rubber and rubber floor tiles. Strong agent.

The high styrene resin has obvious thermoplastic mastication characteristics, and can improve the processing performance of the rubber compound and improve the electrical insulation of the reclaimed rubber vulcanized rubber in the production of recycled rubber products, and has the dual functions of reinforcing and modifying.

4. The role of Gumalon in recycled rubber products

Coumarone resin is often found in rubber product formulations and reclaimed rubber products. It is a copolymer of benzofuran and hydrazine. Its role in rubber is directly related to its softening point. The high softening point of coumarone resin is The organic reinforcing agent commonly used in the production of reclaimed rubber products; and the low softening point of Cumlon can play the role of softening, squeezing and promoting dispersion in the reclaimed rubber, in order to improve the processing performance of the reclaimed rubber.

5. The role of lignin in recycled rubber products

The papermaking waste liquid is precipitated and dried to obtain lignin. The rubber product manufacturer uses lignin as a reinforcing agent, which can significantly improve the elongation at break and tensile strength of the vulcanized rubber, and further improve the rubber elasticity and fatigue resistance. Flexibility. Use reclaimed rubber to produce high-elasticity, low-hardness rubber products such as rubber shoes, tires, etc., and use lignin to reinforce.

It is understood that lignin accounts for about 25%-30% of the biomass material on the earth, and it has multiple functions of reinforcing, flame retardant and anti-aging in rubber rubber; but the strong hydrogen bond contained in the lignin structure leads to Lignin cannot be uniformly dispersed in the rubber compound, and it is easy to agglomerate during kneading. When rubber products are produced using reclaimed rubber, the wear resistance, heat resistance and compression set resistance of the vulcanizate deteriorate with the increase of lignin, which requires special attention.

Other types of organic reinforcing agents will be used in the production of recycled rubber products. Reasonable use of organic reinforcing agents can significantly improve the mechanical strength and process performance of reclaimed rubber vulcanizates. Xiaobian Organic will continue to discuss organic reinforcing agents with you. Application skills in the production of recycled rubber products.
