Problems solved by technology

[0002] The traditional process of producing tread regenerated rubber is to crush the rubber material into powder and then desulfurize it for about 6 hours, and then go through repeated refining in the subsequent process to restore the plasticity of the rubber and meet the corresponding use requirements. This method produces The power consumption per ton of fine recycled rubber reaches about 1200 degrees, high energy consumption, long time and low production efficiency

Embodiment 1

[0014] The process of producing fine recycled rubber is to first inspect the waste tread rubber, remove the non-tread rubber and the sediment impurities attached to the surface, and then crush and granulate the raw materials to achieve a rubber material with a fineness of 30 meshes; The above-mentioned sizing material in parts by weight, 0.1 parts by weight of alkylphenol disulfide, 9 parts by weight of pine tar, and 1 part by weight of rosin are put into a high-temperature and high-pressure dynamic desulfurization device together for desulfurization reaction, and the desulfurization temperature in the desulfurization device is controlled quickly. Raise the temperature to 280°C, the pressure in the cylinder is 3.0Mpa, and the desulfurization time is 1.5 hours. After the desulfurization is completed, rapid cooling is carried out in the desulfurization device. After desulfurization, rapid cooling is carried out in the desulfurization device. After desulfurization, the rubber mate...

[0018] The process of producing fine recycled rubber is to first inspect the waste tread rubber, remove the non-tread rubber and the sediment impurities attached to the surface, and then crush and granulate the raw materials to achieve a rubber material with a fineness of 30 meshes; The above-mentioned sizing material in parts by weight, 0.2 parts by weight of alkylphenol disulfide, 10 parts by weight of pine tar, and 1.5 parts by weight of rosin are put into the high-temperature and high-pressure dynamic desulfurization device together to carry out the desulfurization reaction, and the desulfurization temperature in the desulfurization device is controlled quickly. Raise the temperature to 300°C, the pressure in the cylinder is 3.2Mpa, and the desulfurization time is 2 hours. After the desulfurization is completed, it is quickly cooled in the desulfurization device, and the whole process from feeding to discharging is 2.5 hours. After desulfurization, the rubber material is se...

Abstract

The invention relates to a process method for producing fine reclaimed rubber. The process method comprises the following steps of: putting 100 parts by weight of rubber material, 0.1-0.3 part by weight of antioxidant, 9-11 parts by weight of softening agent and 1-2 parts by weight of plasticizer into a high-temperature and high-pressure dynamic desulfurization device together to perform desulfurization reaction, controlling the desulfurization temperature in the desulfurization device to rapidly increase to 280-300 DEG C, controlling the pressure in a cylinder at 3.0-3.2MPa, controlling the desulfurization time to be 1.5-2.0h, performing rapid cooling in the desulfurization device after the end of desulfurization, and completing the whole process from feeding to discharging within 2.5h; and sending the rubber material after desulfurization into a first milling machine and a second milling machine in batches to perform plastic milling once, further sending into a first refining machine and a second refining machine for refining, rolling the rubber material to a rubber thin-passed sheet with the thickness of 0.05-0.15mm, finally outputting the sheet through a shaping rolling cylinder to obtain a fine reclaimed rubber finished product, and further packaging after metering and cooling. The process method disclosed by the invention has the advantages of energy conservation, high efficiency, economy and environmental friendliness.

Description

Technical field: [0001] The invention relates to a production process of reclaimed rubber, in particular to a process for producing fine regenerated rubber. Background technique: [0002] The traditional process of producing tread regenerated rubber is to crush the rubber material into powder and then desulfurize it for about 6 hours. After repeated refining in the subsequent process, the plasticity of the rubber can be restored to meet the corresponding use requirements. This method produces The power consumption per ton of fine recycled rubber reaches about 1200 degrees, which leads to high energy consumption, long time and low production efficiency. Invention content: [0003] In order to overcome the above-mentioned problems in traditional production, the present invention provides an energy-saving process for producing fine reclaimed rubber, which is energy-saving, highly efficient, economical and environmentally friendly. [0004] The technical solution adopted in t...
