Reclaimed rubber products are environmentally friendly materials, but their mechanical properties are often inferior to raw materials. In order to improve the mechanical properties of reclaimed rubber products, it is often necessary to add additives. This article will introduce the types and functions of commonly used additives for improving the mechanical properties of tire reclaimed rubber products.
1. Reinforcing agent for tire reclaimed rubber
Strengthening agent is an additive that can improve the strength and hardness of reclaimed rubber products. Common reinforcing agents for tire reclaimed rubber include carbon black, silica, graphene, silica powder, glass fiber, etc. Among them, carbon black is the most commonly used reinforcing agent, which can improve the hardness and strength of reclaimed rubber products, and at the same time improve its wear resistance and weather resistance, thereby improving the quality and service life of reclaimed rubber products. .
2. Plasticizer for tire recycled rubber
Plasticizer is an additive that can improve the softness and ductility of reclaimed rubber products. Commonly used plasticizers for tire reclaimed rubber include phthalates, alkyds, fatty acid esters, epoxy esters, polyesters, polyethers, etc. Among them, vegetable pine tar, naphthenic oil, white oil, engine oil, etc. are commonly used, which can improve the softness and ductility of reclaimed rubber products. Phthalates are also used in tire reclaimed rubber to increase viscosity and improve cold resistance and heat resistance.
3. Stabilizer for tire regenerationH2Y3510
A stabilizer is an additive that can improve the aging resistance of reclaimed rubber products. Stabilizers commonly used in tire regeneration include antioxidants, anti-aging agents, and ultraviolet absorbers. Commonly used antioxidants include sulfides, phenols, aromatic amines, etc.; antioxidants include sulfides, aromatic amines, pyridines, etc.; ultraviolet absorbers include benzoate esters, amino acids, triphenyl nitriles wait. These stabilizers can effectively extend the service life of recycled rubber products and improve their heat resistance, oxidation resistance, weather resistance and other properties.
Fourth, fillers for recycled rubber
Filler is an additive that can improve the hardness and strength of reclaimed rubber products. Commonly used fillers include light calcium carbonate, talcum powder, asphalt, fly ash, silica fume, bentonite, graphite, etc. These fillers can increase the volume of recycled rubber, reduce costs, improve processability, increase heat resistance, etc. The type and amount of fillers to be selected need to be determined according to the specific needs of recycled rubber products.
There are various types and functions of additives commonly used to improve the mechanical properties of tire reclaimed rubber products. Choosing the right additives can effectively improve the mechanical properties of reclaimed rubber products, and at the same time improve their wear resistance, weather resistance, and cold resistance. and heat resistance. When using additives, the appropriate type and dosage should be selected according to the requirements of the rubber product index to achieve the best effect.
