When using recycled rubber to produce rubber products, vulcanized rubber powder, short fiber and wood powder are also commonly used organic reinforcing agents and fillers. Reasonable addition can improve the technological properties of rubber materials, improve the comprehensive preparation of rubber products and reduce production costs. The editor will continue to discuss relevant issues with you today.
3. Application of vulcanized rubber powder in recycled rubber products
Vulcanized rubber powder is crushed from waste rubber products, mainly waste tires, and can be added to the production of recycled rubber products again to reduce production costs. In actual production, the finer the filled rubber powder, the closer the tensile strength, elongation at break and wear resistance of the rubber compound are to the level of the rubber powder without adding; Reasonable use of rubber powder can endow recycled rubber with low hardness, low permanent deformation and good thermal stability.
When using recycled rubber to produce bicycle tire tread rubber, rubber sole, rubber gasket, waterproof material, rubber hose, rubber tape and other rubber products, vulcanized rubber powder can be used to fill.
4. Application of short fiber in recycled rubber products
Short fiber is mainly used for rubber and plastics as filler or reinforcing agent. It can be directly added to recycled rubber or used as master rubber. Recycled rubber 2SLY111 can be used as filler or skeleton material when producing rubber soles, heels and industrial rubber products; High quality short fiber can be used in the production of rubber hose and tire compound. When the dosage of short fiber is 15-30 phr, the strength reaches the highest, but the elongation is the lowest.
After short fiber reinforcement is used for recycled rubber products, the rigidity of the fiber and the softness of the recycled rubber can be combined to make the rubber maintain high elasticity and significantly increase the modulus, improve the constant elongation stress, hardness and tear strength of the recycled rubber products, and improve the rubber
Stab resistance, shock absorption and swelling resistance; It should be noted that the addition of short fibers will reduce the elongation and wear resistance of recycled rubber products. It is necessary to control the amount of short fibers reasonably to ensure that the short fibers are evenly dispersed in the rubber compound.
5. Application of wood flour in recycled rubber products
Wood flour can be divided into hard wood flour, soft wood flour, etc. The main component is lignin; When using reclaimed rubber to produce rubber products, it can be used as filling or compatibilizer. When using recycled rubber to produce rubber soles, battery shells and rubber players, wood powder can be used to fill, giving the rubber better stiffness while controlling the shrinkage of semi-finished products. In actual production, cork powder has the lowest volume expansion value when used in oil and water resistant rubber.
When using recycled rubber to produce rubber products, it is recommended to use organic reinforcing agent and filler reasonably. The following editors will continue to share with you the role of inorganic reinforcing agent and filler in recycled rubber products and the addition skills.
