Abstract
The invention relates to a method for quickly desulfurizing waste rubber strips or blocks, which comprises the steps of classifying waste rubber, cutting the waste rubber into rubber strips or rubber blocks containing fibers or not containing fibers, and then putting the rubber strips or rubber blocks into a desulfurizing agent containing chemical substances such as asphalt, coking oil, pine tar, rosin, engine oil, transformer oil, aniline and the like, and desulfurizing the waste rubber at the temperature of 170-270 ℃ for 30-60 minutes under normal pressure.
Description
The present invention relates to a kind of desulfurization regeneration method of waste old, particularly to the fast desulfurization method of the waste rubber strips (blocks) that contains fiber;
Development along with modernization industry, the rubber item of scrapping is also more and more, as tire, adhesive tape and other civilian rubber items etc., because rubber has good chemical stability, so, waste rubber goods can not divide naturally to be taken off, can not lean on the simple combustion method to go to burn, because can be placed with poisonous gas, deposit and to take very big space, to the recycling of waste old, because investment is big, complex process, the cost height, the quality instability of reclaimed rubber can only be utilized a seldom part, the waste old of some developed country has become public hazards, and artificial marine habitat is made in the sea of have to throwing into that has.Seek at present less investment, technology is simple, production cost is low and method high quality reclaimed rubber again has been various countries scientific worker's the objective of the struggle.
Know waste rubber desulfurization regeneration technology at present the high temperature and high pressure steam doctor treatment is arranged, as Chinese patent application 86101191 disclosed " a kind of useless synthetic rubber sulfur removal technology and equipment thereof ", the flow process of this technology is the scrap rubber classification, be ground into 24 purpose rubber powders, rubber powder put into be equipped with 5～10% coumarone in the special-purpose digester, 45～65% Stockholm tar, 2.5～7% rosin, 3～8% 420 activators (polyalkylbenzene phenol disulphide), the regenerator that 10～25% water is formed, in the chuck of digester, adopt thermal oil that material is carried out conduction heating and stir, make the vapour pressure in the jar keep 20 kilograms per centimeter
2, temperature is controlled at 150 ℃～300 ℃, and desulfurization time was at 0.5～3 hour.This technology is the high-temperature high-pressure steam doctor treatment.
Other method is the far-infrared heating method of reproduction.As Chinese patent application 87100611 disclosed " renovation process of waste or used vulcanized rubber ", its technical process is: the scrap rubber classification, powder sulphur becomes less than-36 purpose rubber powders, the same Stockholm tar of rubber powder, transformer oil, rosin or aniline are mixed, mixing in mill, put into the far infrared case then and add thermally desulfurizing, allocate dispersion agent refining more at last into, the production cycle is 6～7 hours.
The pulverizing process that waste rubber is all arranged in above-mentioned two kinds of technologies, this operation power consumption is big, dust is big, noise is big, and investment is high, and the fibre-bearing scrap rubber can not be used, and the water consumption is high.Chinese patent application 87101547 discloses the breaking method and the device of waste old.
The purpose of this invention is to provide that a kind of facility investment is few, technology is simple, power consumption is low, desulfurization time fast, reclaimed rubber quality height, easy and simple to handle.The waste old bar or the desulfurization rapidly renovation process of piece.
The objective of the invention is to realize in the following manner:
1, with the scrap rubber classification, is cut into the adhesive tape or the blob of viscose that are easy to load and unload.
2, preparation sweetening agent, its component contains:
0～5 part of 0.5～1 part of coumarone of 10～15 parts of aniline of 7～15 parts of machine oil of 3～15 parts of transformer oil of 5～25 parts of rosin of 4～25 parts of Stockholm tars of 40～90 parts of coking oil of pitch
3, adhesive tape or blob of viscose input are filled in the digester of sweetening agent or in the common vessel, desulfurization at normal-pressure 30～60 minutes, temperature is controlled at 170～270 ℃
4, the adhesive tape after the desulfurization or blob of viscose are pulled out from sweetening agent directly carried out the kneading refining.
Pitch in the prescription is the petroleum pitch or the coal-tar pitch of all size.
Fast desulfurization method of the present invention, waste old is carried out slitting or stripping and slicing, saved complicated disintegrating apparatus, be cut into the stick that is easy to load and unload, generally about 10cm * 15cm * 1.5cm, or about 1.5cm * 5cm * 15cm, the fiber in adhesive tape, the blob of viscose needn't separate, and this is the main difference with prior art.In the prior art, shoddy needs to remove fiber through selection by winnowing after being broken into rubber powder, just enters desulfurization process then, also will be after the desulfurization through the flushing press filtration, and 40～60 tons of one ton of reclaimed rubber water consumptions of every production cause the very big useless and dust pollution of water resources wave.
The reclaimed rubber that the present invention produces has good physical property, and chemical stability, its reason is: adhesive tape or blob of viscose have less surface-area, sweetening process is a solid-liquid reaction, the less sweetening agent of adhesive tape or blob of viscose absorption after the desulfurization is so in the kneading of back operation, refining, sweetening agent contained in the reclaimed rubber is few more than rubber powder, so the reclaimed rubber that physical property and chemical stability are produced more than prior art will be got well, and does not have dust pollution in the production process.In addition, the water content of reclaimed rubber also is the important factor that influences quality.In sulfur method of the present invention, there is not the adding of water, so be not with moisture content in the reclaimed rubber, need not carry out drying and dewatering to the reclaimed rubber after the desulfurization and handle, can directly carry out the kneading refining.
The sulfur method of waste rubber strips (blocks) fast desulfurization method of the present invention and prior art is compared, it is extensive to have the sweetening agent raw material sources, production technique is simple, low for equipment requirements, take and lack, power consumption is few, with short production cycle, reclaimed rubber quality height, advantage such as production cost is low is for the regeneration of waste old provides comparatively economic method.
Except that technical characterictic of the present invention, be those skilled in the art of the present technique's known technology.
Table A is the correlation data of the present invention and prior art gained reclaimed rubber
Table B is one group of embodiment of the present invention.
