All living organic matter that can grow can be referred to as biomass, including plants, animals and microorganisms. Therefore, biomass additives are impurities that exist in nature and can be regenerated. Recycled plastic industry need to use a lot of biomass additives, most of them can be used for environmentally friendly recycled rubber and its products in the production. Such as cellulose, lignin, starch can be used as reinforcing rubber reinforcing filler, pine tar, rosin, tall oil, black ointment, white ointment can be used as a reclaimed rubber softening plasticizer.
Cellulose short fibers can be used as a rubber reinforcing agent directly with the regeneration of rubber compound with the rubber to improve the stress and improve strength, but it is poor compatibility with recycled rubber, reinforcing effect is not ideal; lignin Used in the production and processing of latex reclaimed rubber. It can replace the traditional carbon black as a reinforcing effect, and has certain anti-aging effect. Starch can be directly mixed in the rubber product production. It can be used with rubber compound to replace the carbon produced by petrochemical resources Black, save petrochemical resources, reduce carbon dioxide emissions and carbon black production of high energy consumption.
Pine tar and rosin belong to the softening plasticizer of biomass, among them: pine tar used in reclaimed rubber and products is dark brown to black viscous liquid, which can penetrate evenly to the middle of regenerated rubber rubber macromolecule containing sulfur, Plastic material swelling, internal network structure relaxation, increase the distance among the regenerated molecular chains and oxygen penetration can also be used as a free radical receptor, inhibition of gelation, help activator diffusion and obvious Improve the viscosity of the reclaimed rubber, plasticity and processing technology performance; rosin in the rubber field generally do softener, can increase the flexibility of recycled rubber, rubber compound to improve adhesion and promote the distribution of various compounds in the rubber to prevent scorching .
Tall oil and black and white ointment are the common bio-rubber oils used in the production of reclaimed rubber products. Among them, tall oil not only can be used as softener, but also improve the adhesiveness, heat resistance and aging resistance ; Black ointment and white ointment can improve the processing performance of the recycled rubber compound. The produced reclaimed rubber has good calendering and extruding properties during the production of the product, which helps the smooth release of the reclaimed rubber product.
Biomass reclaimed rubber additives produce less pollution in the processing of reclaimed rubber products, and the reclaimed rubber products produced by the reclaimed rubber products can meet the tasteless and environmental protection requirements and can be easily staged in the market. Reclaimed rubber products using biomass additives, according to the needs of reclaimed rubber products choose the right species, the rational formulation of dosage, in order to improve the quality of reclaimed rubber products to the best.
