Rubber is an important industrial raw material, widely used in tires, seals, pipelines and other fields, but the production process of rubber products will produce a large amount of waste, rubber products after scrapping disposal problems have become a global problem, such as waste tires in nature in the short term can not decompose, has become "black pollution". How to use this waste effectively has become an important issue for the rubber industry.
In recent years, the use of waste tires to produce tire recycled rubberor thermal cracking of waste tires has become the mainstream way to solve black pollution, among which tire recycled rubber is widely used in the production of corn peeling machine rubber rollers due to good wear resistance and anti-aging performance, and has achieved good economic benefits. The production of corn peeling machine rubber roller vulcanization formula and process is as follows:
1. Raw materials and formula of rubber roller for tire regeneration rubber production corn peeling machine:
①. Reclaimed rubber: Reclaimed rubber is the main component of tire reclaimed rubber, and its quality directly affects the performance of rubber rollers. Generally speaking, the content of recycled rubber should be above 70%.
②. Filler: Filler can increase the hardness and strength of rubber roller, commonly used fillers are carbon black, silica black, silica fume, etc.
③. Plasticizer: plasticizer can increase the softness and ductility of rubber roller, commonly used plasticizers are rubber oil, paraffin wax, etc.
④. Vulcanizing agent: Vulcanizing agent is an important part of the rubber roller, which can make the rubber roller form a cross-linked structure after heating, so as to obtain good physical properties. Commonly used vulcanizing agents are sulfur, peroxide and so on.
Type B high strength tire top reclaimed rubber 20kg, black sub-brand natural rubber 8kg, 1502 styrene-butadiene rubber 2kg, N330 carbon black 6.5kg, light calcium carbonate 5kg, engine oil 1.3kg, paraffin 120g, PEG4000 auxiliaries 230g, activated zinc oxide 750g, stearic acid 500g, antioxidant RD150g, accelerator CZ140g, accelerator DM120g, accelerator TT50g, sulfur 350g, vulcanization temperature 145 °C, adjust the vulcanization time according to the thickness, generally 4-8 minutes
2. the process of tire regeneration rubber production corn peeling machine rubber roller mainly includes the following steps:
①. Mixing: the recycled rubber, filler, plasticizer, vulcanizing agent, etc. are mixed together in a certain proportion, and mixed by the mixer to fully mix various raw materials.
②. Molding: the mixed rubber material cutting strip is weighed and put into the mold of the plate vulcanizing machine to press and form.
③. Vulcanization: Heat and pressure the rubber in the mold for vulcanization treatment, pay attention to exhaust. When vulcanizing, it is necessary to control the temperature and time to ensure the degree of vulcanization of the rubber roller.
④. Cutting: The vulcanized rubber roller is cut to make the desired length and shape.
Tire regeneration rubber production corn peeler rubber rods also have the following advantages:
1. Environmental protection: tire recycling rubber is the reuse of waste tires, which can effectively reduce the generation of waste and reduce environmental pollution.
2. Economy: The price of tire recycled rubber is cheaper than natural rubber and synthetic rubber, which can reduce production costs and improve economic benefits.
3. Stable performance: The performance of tire recycled rubber is stable, which can meet the technical requirements of rubber rollers of corn peeling machine.
4. Strong plasticity: tire reclaimed rubber can be blended with a variety of raw rubber according to needs, which has strong plasticity and can meet the needs of different rubber roller indicators.
Tire reclaimed rubber production corn peeler rubber rod is a new type of rubber material with environmental protection, economy, stable performance and strong plasticity, which has broad application prospects. Through reasonable formula and fine process control, high-quality rubber rollers can be produced and contribute to the sustainable development of the rubber industry.
