Recycled rubber refers to the recycling of waste rubber products,

after desulfurization treatment can be reused rubber materials, with similar performance to the original rubber, many customers in order to reduce costs, energy saving and environmental protection, mixed with part of the recycled rubber to produce rubber products, the production and processing process needs to use some rubber accessories to improve the performance and processability of rubber, let's introduce the types and functions of rubber accessories commonly used in HONG YUN recycled rubber.

1. Plasticizer

Plasticizer is a chemical used to increase the elasticity and softness of rubber, commonly used plasticizers are DBP, DOP, DINP, paraffin oil, lubricating oil, pine tar, etc. They can make recycled rubber easier to process and mold and improve its wear and cold resistance. At the same time, plasticizers can also reduce the hardness and viscosity of recycled rubber, and improve the plasticity and processability of rubber.

2. Accelerator

Accelerator is a chemical used to accelerate the rubber vulcanization reaction, commonly used accelerators are M, DM, MBT, MBTS, CBS and so on. They can increase the vulcanization rate and degree of vulcanization of rubber, thereby enhancing the strength and durability of rubber. At the same time, the accelerator can also improve the processing performance of rubber and increase the plasticity of rubber.

3. Antioxidant

Antioxidants are chemicals used to prevent rubber aging. In the production process of yyE30609 recycled rubber processing products, commonly used antioxidants are 4010NA, 4020, RD, etc. They extend the life of the rubber and maintain its elasticity and softness. At the same time, the antioxidants can also improve the heat resistance and oxidation resistance of rubber, and prevent aging of rubber during production and use.

4. Reinforcing agent

Reinforcing agent is a chemical used to enhance the strength and hardness of rubber, commonly used reinforcing agents are carbon black, silica and so on. They can make rubber products stronger and more durable, and improve their tensile strength and wear resistance. At the same time, the reinforcing agent can also improve the processing performance of rubber and increase the hardness of rubber.

5. Vulcanizing agent

Vulcanizing agent is a chemical substance used to promote the vulcanization reaction of rubber, commonly used vulcanizing agents are sulfur, DCP and so on. They allow the rubber to form a cross-linked structure, which enhances the strength and durability of the rubber.

The selection of auxiliary materials in the process of recycled rubber production products also needs to pay attention to the following points:

1. High quality requirements for auxiliary materials: the quality of rubber accessories directly affects the quality and performance of rubber products

, so when selecting rubber accessories, we should choose products with stable quality and reliable performance to ensure the quality and performance of rubber products.

2. The ratio of auxiliary materials should

be reasonable: different rubber auxiliary materials have different effects on the performance of recycled rubber, so the appropriate rubber auxiliary materials should be selected according to the specific production requirements and rubber performance requirements when proportioning, and the ratio should be scientific and reasonable to achieve the best performance effect.

3. Dispersion of auxiliary materials: During the processing of rubber auxiliary materials,

attention should be paid to the control of processing temperature, processing time, processing pressure and other factors to ensure the full dispersion and uniform distribution of rubber auxiliary materials, so as to ensure the quality and performance of recycled rubber.

The storage of

auxiliary materials should pay attention to: During the storage of rubber accessories, attention should be paid to the influence of moisture-proof, sunscreen, high-temperature and other factors to avoid the quality of rubber accessories being affected, thereby affecting the quality and performance of recycled rubber.

The production process of recycled rubber requires the use of a variety of rubber accessories to improve the properties and processability of the rubber. The choice and use of these rubber excipients has a crucial impact on the quality and performance of recycled rubber. Therefore, in the production process of recycled rubber, it is necessary to select the appropriate rubber accessories according to the specific production requirements and rubber performance requirements, and carry out scientific and reasonable proportioning and processing to ensure the quality and performance of recycled rubber.
