Problems solved by technology

[0002] The traditional process of producing butyl regenerated rubber is to crush the rubber material to 30-40 mesh rubber powder, then desulfurize it for about 6 hours, and then go through repeated refining in the subsequent process to restore the rubber plasticity and achieve the corresponding use. Requirements, this method produces about 1200 degrees of electricity per ton of butyl reclaimed rubber, high energy consumption, long time, and low production efficiency

Embodiment 1

[0013] The process of producing butyl regenerated rubber is to first inspect the waste butyl rubber, remove non-butyl rubber, and then send it to a washing machine for cleaning to remove sediment and impurities attached to the surface; then crush and granulate the raw materials , to reach 2-mesh fineness rubber; put 100 parts by weight of the above rubber, 0.2 parts by weight of alkylphenol disulfide, and 1 part by weight of paraffin oil into a high-temperature and high-pressure dynamic desulfurization device for desulfurization reaction, control desulfurization The desulfurization temperature in the device rises rapidly to 190°C, the pressure in the cylinder is 2.1Mpa, and the desulfurization time is 1.5 hours. After the desulfurization is completed, the desulfurization device is rapidly cooled, and the whole process from feeding to discharging is completed within 2.5 hours; after desulfurization The rubber material is sent to the kneader in batches for a plastic rubber mixing...

Embodiment 2

[0015] The process of producing butyl regenerated rubber is to first inspect the waste butyl rubber, remove non-butyl rubber, and then send it to a washing machine for cleaning to remove sediment and impurities attached to the surface; then crush and granulate the raw materials , sizing material with a fineness of 4 meshes; put 100 parts by weight of the above-mentioned sizing material, 0.3 parts by weight of antioxidant, and 2 parts by weight of softener into a high-temperature and high-pressure dynamic desulfurization device for desulfurization reaction, and control the desulfurization in the desulfurization device. The desulfurization temperature is rapidly raised to 200°C, the pressure in the cylinder is 2.15Mpa, and the desulfurization time is 1.8 hours. After desulfurization, it is quickly cooled in the desulfurization device. The whole process from feeding to discharging is completed within 2.5 hours; after desulfurization, the rubber Send the kneader in batches for a pl...

Embodiment 3

[0017] The process of producing butyl regenerated rubber is to first inspect the waste butyl rubber, remove non-butyl rubber, and then send it to a washing machine for cleaning to remove sediment and impurities attached to the surface; then crush and granulate the raw materials , to reach 5-mesh fineness rubber compound; put 100 parts by weight of the above rubber compound, 0.23 parts by weight of antioxidant, and 1.5 parts by weight of softener into a high-temperature and high-pressure dynamic desulfurization device for desulfurization reaction, and control the desulfurization device. The desulfurization temperature is rapidly raised to 210°C, the pressure in the cylinder is 2.2Mpa, and the desulfurization time is 2.0 hours. After desulfurization, it is cooled rapidly in the desulfurization device. The whole process from feeding to discharging is completed within 2.5 hours; after desulfurization, the rubber Send the kneader in batches for a plastic rubber mixing, so that the r...

Abstract

The invention relates to a process method for producing butyl reclaimed rubber. The process method comprises the following steps of: putting 100 parts by weight of rubber material, 0.2-0.3 part by weight of antioxidant and 1-2 parts by weight of softening agent 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 190-210 DEG C, controlling the pressure in a cylinder at 2.1-2.2MPa, 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; sending the rubber material after desulfurization into a milling machine in batches to perform plastic milling once, rolling the rubber material into a rubber sheet with the thickness of 60-80mm under the mechanical action of the milling machine, then sending the rubber sheet after primary shaping into a refining machine for thin-passing processing, and rolling the rubber material into a rubber thin-passed sheet with the thickness of 0.1-0.15mm under the mechanical action of the refining machine; and finally outputting the sheet through a shaping rolling cylinder to obtain a fine reclaimed rubber finished product. 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 butyl regenerated rubber. Background technique: [0002] The traditional process of producing butyl regenerated rubber is to crush the rubber material to 30-40 mesh rubber powder, then desulfurize it for about 6 hours, and then go through repeated refining in the subsequent process to restore the rubber plasticity and achieve the corresponding use. Requirements, this method produces about 1200 degrees of power consumption per ton of butyl regenerated rubber, 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 butyl regenerated rubber, which is energy-saving, highly efficient, economical and environmentally friendly. [0004] The technical scheme adopted in...
