The production process and technical characteristics of tire rubber vary depending on the type and purpose of the product, but generally speaking, its production process mainly includes steps such as raw material preparation, mixing, molding, vulcanization, etc. The technical characteristics are mainly reflected in raw material selection, formula design, production process control, etc. The following is a detailed explanation of the production process and technical characteristics of tire rubber:
1、 Production process
Raw material preparation
The main raw materials for tire rubber include natural rubber, synthetic rubber (such as styrene butadiene rubber, butadiene rubber, etc.), fillers (such as carbon black, white carbon black, etc.), plasticizers, vulcanizing agents, etc. The selection and ratio of these raw materials directly affect the performance of tire rubber.
Mixing
Put the prepared raw materials into the mixer for mixing, so that all kinds of raw materials are fully mixed evenly, forming a rubber material with certain plasticity and fluidity. During the mixing process, it is necessary to control parameters such as temperature, time, and pressure to ensure the mixing effect.
forming
Put the mixed rubber material into the tire mold and shape it through methods such as injection molding, extrusion, or injection molding. During the molding process, it is necessary to control parameters such as mold temperature and injection pressure to ensure that the shape and size of the tire meet the requirements.
vulcanization
Sulfurization is a chemical reaction that occurs under high temperature and high pressure conditions to form cross-linked structures between rubber molecular chains, thereby improving the strength and wear resistance of tires. During the vulcanization process, it is necessary to control parameters such as vulcanization temperature, time, and pressure to ensure the vulcanization effect.
2、 Technical features
Raw material selection
The selection of raw materials for tire rubber needs to be based on the tire's usage environment and performance requirements. For example, for tires that require high wear resistance, one can choose styrene butadiene rubber or butadiene rubber with good wear resistance; For tires that require high elasticity, natural rubber or isoprene rubber can be chosen.
Formula design
Formula design is a crucial step in tire rubber production. By adjusting the ratio of raw materials and adding appropriate additives, the performance of tire rubber can be optimized, such as improving wear resistance, aging resistance, tear resistance, etc. Formula design needs to be based on the specific purpose and usage environment of the tire.
Production process control
Production process control is the key to ensuring stable quality of tire rubber. During the production process, it is necessary to strictly control parameters such as temperature, time, and pressure to ensure the smooth progress of each process and the stability of tire rubber performance. In addition, regular maintenance and upkeep of production equipment are necessary to ensure its normal operation and extend its service life.
Environmental Protection and Sustainability
With the increasing awareness of environmental protection, the production of tire rubber is also paying more and more attention to environmental protection and sustainability. For example, adopting environmentally friendly raw materials and additives, optimizing production processes to reduce energy consumption and emissions, and recycling and reusing waste tires are all important trends in current tire rubber production.
In summary, the production process and technical characteristics of tire rubber involve multiple aspects, which require comprehensive consideration of factors such as raw material selection, formula design, production process control, environmental protection, and sustainability. By continuously optimizing production processes and technological features, the performance and quality of tire rubber can be improved, meeting market demand and consumer expectations.
