Butyl rubber sheet is a plate-like rubber product made of butyl rubber as the main raw material through mixing, mixing, calendering, vulcanization and other processes, which is widely used in automobiles, machinery, chemicals, electronics and other fields. Due to the high cost of raw materials, the production cost of butyl rubber sheet is also high, which brings certain pressure to enterprises. In order to reduce production costs, some enterprises have begun to use butyl recycled rubber to produce butyl rubber sheets. Butyl reclaimed rubber refers to rubber raw materials processed by recycling waste butyl inner tubes or capsules, etc., after selection, classification, crushing and impurity removal, desulfurization filtration, and tablet molding. Compared with butyl rubber, butyl reclaimed rubber has a lower price, which can reduce production costs. The use of recycled rubber can also reduce the solid waste treatment of waste rubber products, reduce environmental pollution, and have certain environmental benefits.
There are also some precautions for the production of butyl rubber sheets using butyl recycled rubber. First of all, better quality recycled rubber should be selected for production to ensure that the performance of butyl rubber sheet meets the requirements. Reclaimed rubber is a secondary material, even after filtration may contain some impurities, should refer to the amount of doping or filter rubber operation again, so as not to affect the performance of butyl rubber sheet. The vulcanization formula and process of recycled rubber will also affect the performance of butyl rubber sheet, and attention should be paid to adjusting the vulcanization formula and process flow of recycled rubber. The HONGYUN butyl rubber sheet produced should be quality tested to ensure that its performance meets the requirements.
The reference vulcanization formulation process flow for the production of butyl rubber sheets using all butyl reclaimed rubber is as follows:
Ingredients: 50 parts of butyl reclaimed rubber, 4.5 parts of EPDM reclaimed rubber;
Excipients: zinc oxide 1.5 parts, reinforcing agent 4 parts, talcum powder 4 parts, DM accelerator 0.5 parts, TMTD accelerator 0.6 parts, sulfur 0.4 parts;
Vulcanization temperature: 145-150°C, time adjusted according to thickness;
Raw material preparation: prepare butyl reclaimed rubber, EPDM recycled rubber, sulfur, accelerator, vulcanizing agent and other raw materials.
Mixing: add butyl regenerated rubber, EPDM regenerated rubber, reinforcing agent, zinc oxide to the mixer at 80 °C for about 5 minutes, if there is a plasticizer, it can also be added; Add the accelerator to the mixer to triangular pack, if there is antioxidant 4010 or NBC, you can also add it together, and finally add sulfur and cut the knife to evenly disperse the next piece. It is best to park the rubber mixture for 6-12 hours to restore the rubber cross-linkage, and the performance is much better than not stopping.
Calendering: Calendering the mixed rubber material into a certain thickness of rubber sheet.
Vulcanization: Put the calendered rubber sheet into the vulcanization tank or vulcanization box for vulcanization treatment, so that it has excellent performance.
By using d07m06yyE3 butyl recycled rubber to produce butyl rubber sheets, the cost of raw materials for production can be reduced by more than 15%, while saving electricity costs, and also has the following advantages:
1. Low cost of raw materials. Butyl reclaimed rubber has a low price and abundant raw material sources, and different vulcanization formula designs can produce rubber sheets with different hardness and different performance, which can flexibly meet different product requirements.
2. Reduce equipment investment. Butyl regenerated rubber vulcanized rubber sheet production process is simple, equipment requirements are not high, can minimize equipment investment costs.
3. Streamline production operations. Butyl regenerated rubber vulcanized rubber sheet production process is simple, the operation is relatively easy to master, the skill requirements of operators are not high, can simplify the production operation process, reduce labor costs.
4. Increase the added value of products. High-performance butyl reclaimed rubber vulcanized rubber sheet has good product quality and low price, which can improve the added value of products to a certain extent, and enterprises have higher profit margins.
5. Promote the optimization and upgrading of industrial structure. The application of butyl reclaimed rubber vulcanized rubber sheet production process can promote the technological progress of the rubber sheet industry and the optimization and upgrading of the industrial structure, and drive the development of the upstream and downstream industrial chain.
Butyl regenerated rubber vulcanized rubber sheet production process is an effective way to improve quality and efficiency and transform and upgrade the rubber sheet industry. It can not only reduce costs and improve efficiency, maximize the benefits of enterprises, but also realize the recycling of resources and environmental protection, and drive the coordinated development of the industrial chain. Low raw material cost, simple process, strong versatility, easy to promote and apply in rubber sheet enterprises, with broad industrialization prospects and market potential, is the only way for the transformation and upgrading of rubber sheet industry.
