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:
The present invention relates to a kind of production technique of reclaimed rubber, relate in particular to the processing method of producing butyl renewable rubber.
Background technology:
The processing method of traditional mode of production butyl renewable rubber is sizing material desulfurization about through 6 hours after being crushed to 30-40 order rubber powder, again through later process will through repeatedly repeatedly refining could recover rubber plasticity, reach corresponding service requirements, this method is produced butyl renewable rubber current consumption per ton and is reached about 1200 degree, and the energy consumption height, the time is long, production efficiency is low.
Summary of the invention:
The present invention overcomes the problem that above-mentioned traditional mode of production exists, and provides a kind of processing method of energy-saving production butyl renewable rubber, this processing method efficient energy-saving, economic environmental protection.
The technical solution used in the present invention is: produce the processing method of butyl renewable rubber, earlier waste butyl rubber is tested, reject non-butyl rubber, send into cleaning machine then and clean, eccysis silt and be attached to the impurity on surface; Then raw material is pulverized granulation, reach the sizing material of 2-5 order fineness; The tenderizer of the oxidation inhibitor of the above-mentioned sizing material of 100 weight parts, 0.2-0.3 weight part, 1-2 weight part put in the dynamic desulfurizer of High Temperature High Pressure together carry out desulphurization reaction, desulfurization temperature in the control desulfurizer is rapidly heated 190-210 ℃, in-cylinder pressure 2.1-2.2Mpa, desulfurization time 1.5-2.0 hour, cool off in desulfurizer fast the intact back of desulfurization, finishes in 2.5 hours from the whole process that is fed to discharging; Sizing material send milling machine to carry out plasticity refining glue one time after the desulfurization, make sizing material under the mechanical effect of milling machine, roll into the sheet rubber that thickness is the 60-80 millimeter, sheet rubber with preliminarily forming send the processing of refiner thin-pass then, make sizing material under the mechanical effect of refiner, roll into the rubber thin-pass sheet that thickness is the 0.1-0.15 millimeter, at last by moulding coiled strip tube slice, namely get the fine renewable rubber finished product, at last by metering cooling back packing.
Described oxidation inhibitor is the curing alkylphenol.
Described tenderizer is paraffin oil.
The required heat energy of described sweetening process is electrically heated.
Waste water in the described desulfurizer cylinder is discharged and is handled by the vent gas treatment refining plant.
The present invention is in sweetening process, and rubber powder is under high temperature, high pressure, dynamic action, and degraded and quick process of cooling take place at short notice fast for its C-C or C-S molecular linkage, and required heat energy is provided by electrically heated in the regenerative process.
Rubber powder of the present invention is rapidly heated to finish whole sweetening process in the dynamic desulfurizer of High Temperature High Pressure, rubber powder can reach the plasticity-requirement through a banburying and initial refining, it produces only power consumption 900 degree of butyl renewable rubber per ton, this project is to produce 6000 tons of calculating per year, 1,800,000 kilowatt-hours of can economizing on electricity every year, this technology belongs to Increasing Production and Energy Saving type technology, also meets the renewable resource recycling economy industry that country encourages.
Waste water in the desulfurizer cylinder after sweetening process of the present invention finishes is discharged and is handled by the vent gas treatment refining plant, be mixed with other chemical substance that certain tenderizer, regenerator and rubber implosion solve in the aqueous vapor of discharging after the desulfurization, after the processing by this vent gas treatment refining plant, no waste gas, water generates discharging.
