Abstract
The invention relates to a new material production technology of rubber filling oil of a refinery, in particular to a method for producing an electrical brush adhesive by using the rubber filling oil. The technical proposal of the invention includes the following technical steps: (1) introduce the rubber filling oil into a heating pot to carry out high temperature pyrolysis; (2) carry out physical separation to raw oil treated with high temperature processing under reduced pressure condition; (3) light components separated out can be re-used as raw materials of a refinery, while obtained heavy components, i.e. components rich in aromatic hydrocarbon enter a composition pot to carry out synthetic reaction; (4) carry out synthetic reaction to obtain resin, discharge for cooling, and break the resin into pieces to obtain the finished product. The beneficial effects of the invention are that: by utilizing cheap and easily-obtained by-products of the refinery and adopting a simple and easily-controlled far-infrared means to obtain the high-added-value resin, not only the demands for high-class adhesives in electrical brush industry is solved, but also the purpose of the invention is extended and the value added is increased.
Description
One, technical field:
The present invention relates to a kind of new material production of refinery byproduct rubber filling oil, particularly a kind of method of producing electrical brush adhesive with rubber filling oil.
Two, background technology:
Rubber filling oil is as a kind of byproduct of lubricated oil type refinery, substantially the packing material as the rubber production industry simply utilizes, main tenderizer or PVC softening agent as rubber items such as tires, can obviously improve the plasticity-of rubber and the degree of scatter of filler, make that the rubber product rebound resilience is good, acid resistance is strong, it is narrower that but the problem of its existence is a purposes, and added value is low.And traditional electrical brush adhesive generally utilizes resol, Resins, epoxy and middle high temperature coal-tar pitch, the brush of producing is in more low-grade, various performance parameters such as the work-ing life of brush, EMC, specific conductivity, frictional coefficient can't be compared with external high-grade brush, and a kind of electrical brush adhesive material of efficient and cheap is brush industry a kind of objective demand for many years.
Three, summary of the invention:
Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, a kind of method of producing electrical brush adhesive with rubber filling oil is provided, for making full use of of refinery residual oil sought a kind of new outlet, produce high value-added product, solved the demand of the high-grade brush of brush industry production simultaneously binding agent.
Its technical scheme is: comprise following processing step:
(1) rubber filling oil enters in the heating kettle, carries out Pintsch process;
(2) stock oil finished of pyroprocessing carries out physical sepn under reduced pressure;
(3) isolated light constituent can be used as refinery stock and utilizes again, and the heavy constituent that obtain are that rich aromatic component enters polymeric kettle and carries out building-up reactions;
(4) building-up reactions obtains resin, and the discharging cooling is pulverized and obtained finished product.
Wherein, rubber filling oil is the byproduct of refinery in the described step (1), carries out high-temperature heat treatment at the high-temperature heat treatment still, and temperature is controlled between 390 ℃～410 ℃, and the treatment time remained on 5-6 hour.
In high-temperature heat treatment still treating processes, equipment keep-ups pressure and is that normal pressure, stir speed (S.S.) remain on 60-70 rev/min.
In addition, the stock oil after the described pyroprocessing of above-mentioned steps (2) utilizes interchanger to reduce temperature, enters the reduced pressure treatment still, utilizes vacuum generating device slowly to reduce the still internal pressure, till-700mmHg pressure; Medium in the beginning heating kettle, Heating temperature remains between 250-290 ℃, till not having cut to separate out.
The described heavy constituent of above-mentioned steps (3) are rich aromatic component polymeric material, utilize interchanger to reduce temperature, are input in the polymeric kettle; normal pressure is stirred in nitrogen protection; add phenyl aldehyde; maintain the temperature at more than 90 ℃, add catalyzer dilute sulphuric acid or dilute hydrochloric acid, slowly elevated temperature carries out polyreaction; to reaction end; stopped reaction is dumped in the stock chest and cools off, and pulverizes to obtain product.
Wherein, the concentration of above-mentioned phenyl aldehyde is mass ratio 3%.
The invention has the beneficial effects as follows: utilize refinery's byproduct cheap and easy to get, adopt production technique simple and easy to control, obtain the resin of high added value, both solved the demand of brush industry, expanded its purposes simultaneously, improved added value high-grade binding agent.
Four, description of drawings:
Accompanying drawing 1 is a process flow diagram of the present invention.
Five, embodiment:
In conjunction with the accompanying drawings 1, to produce 300 tons of copna resin scale design per year, the invention will be further described:
1, being raw material with the refinery rubber filling oil, remaining on more than 60 ℃ that this raw material has good flowability, is 2M with volume
3The high-temperature heat treatment still carry out high-temperature heat treatment, temperature is controlled between 390 ℃～410 ℃, adopt to stir, stir speed (S.S.) remains on 60-70 rev/min.In the treating processes, temperature can not surpass 410 ℃, otherwise be easy to generate overheated, saboteur's structure and the charing coking phenomenon occurs, the pyroprocessing time remained on 5-6 hour.In the high-temperature heat treatment still treating processes, equipment keep-ups pressure and is normal pressure, external light oil output tube, adopt type of heating such as chuck thermal oil or electric heating tube direct heating, equipment is incubated outward, need have the product that diamagnetism requires at carbon brush etc., and equipment material adopts stainless steel, avoid the free iron ion to enter product, influence the product result of use.
2, the stock oil after the pyroprocessing, utilize interchanger to reduce the temperature to about 250 ℃, enter the reduced pressure treatment still, reduced pressure treatment still equipment material is a stainless steel, requirement can be carried-1.0Mpa pressure, utilize vacuum generating device slowly to reduce the still internal pressure, till-700mmHg pressure, medium in the beginning heating kettle is separated in cracked small molecules in the high-temperature process, mainly is short chain straight chain unsaturated hydrocarbons, Heating temperature remains between 250-290 ℃, till not having cut to separate out, adopt and stir, 60 rev/mins of speed.
3; separate the heavy constituent that obtain in the reduced pressure treatment still, be polymer raw, utilize interchanger to reduce the temperature to 90 ℃; be input in the polymeric kettle; normal pressure is stirred in nitrogen protection; phenyl aldehyde according to mass ratio adding 3%; be linking agent, maintain the temperature at more than 90 ℃, slowly heating; after mixing in about 20 minutes; add catalyst quality than being that 10% dilute sulphuric acid or mass ratio are 10% dilute hydrochloric acid, quality is 5% of a polymer raw, about slow elevated temperature to 130 ℃; under this temperature, carry out polyreaction; 30 minutes time, to reaction end, stopped reaction; be dumped in the stock chest and cool off, pulverize and obtain product.
