Description
Technical field
The present invention relates to a kind of flexible pipe and preparation method, a kind of specifically mine plastic hose and preparation method thereof.
Technical background
Gas is to be formed through anaerobic digestion by cellulose and organic matter at the coal formation initial stage, continues to generate under high temperature, high pressure.Gas is insoluble in water, and penetrating power is 1.6 times of air, can not keep the eupnea of humans and animals, reaching finite concentration can make humans and animals die because of being choked to death, easily blast when serious, cause casualties by gas explosion under a lot of mines at present, and cause serious economy loss.
The pipeline that is used for gas extraction under the mine at present mostly is PE pipe, hard tube or polyethylene pipe greatly, because road curved way and these pipelines all exist not flexiblely under the mine, can't be applied under the mine, and sealing effect is poor, and gas leakage easily takes place; And high-temperature condition can not appear under mine, and these pipelines all do not have antistatic and fire-retardant effect, in case because friction-produced static, the pipeline burning easily takes place, and because pipeline does not possess character such as fire-retardant ability and gas is inflammable and explosive, gas ignition or gas explosion take place easily, cause casualties, increase cost of production, reduce economic benefit.
Summary of the invention
The objective of the invention is deficiency for solving the problems of the technologies described above, provide a kind of mine with plastic hose and preparation method, have antistatic and fire retardation, its crank throw is easy to bending greatly, is convenient to the link of pipeline enclosure, and good sealing effect, cost of production reduces, and enhances productivity its preparation method, simple easy operating saves production cost.
The present invention is the deficiency that solves the problems of the technologies described above, and the technological scheme that is adopted is: a kind of mine plastic hose flexible pipe, and plastic hose is made up of plastics soft formation and the steel wire that is embedded in the plastic cement soft formation; The raw material that plastic layer is soft is made up of PVC, dibutyl phthalate, chlorinated paraffin-52, stabilizer, stearic acid, fire retardant and carbon black, and the parts by weight of each raw material addition are: 90-110 parts of PVC, 28-34 parts of dibutyl phthalates, 36-44 parts of chlorinated paraffin-52s, 3-5 parts of stabilizers, 1 part of stearic acid, 7-9 parts of fire retardants and 14-16 parts of carbon blacks.
Described stabilizer is any one in organic tin stabilizer or the calcium-zinc composite stabilizing agent.
A kind of mine preparation method of plastic hose:
Step 1, get PVC respectively, dibutyl phthalate, chlorinated paraffin-52, stabilizer and stearic acid are raw material, earlier 90-110 parts of PVC are put into high-speed mixer, rotating speed with 300-500 rev/mins mixes, add 14-17 parts of dibutyl phthalates when stirring, 18-22 parts of chlorinated paraffin-52s, 1.5-2.5 parts of stabilizers and 0.5 part of stearic acid, be stirred to when material temperature is 50 ℃ in the high-speed mixer, add 14-17 parts of dibutyl phthalates again, 18-22 parts of chlorinated paraffin-52s, 1.5-2.5 parts of stabilizers and 0.5 part of stearic acid, stir with 500-700 rev/mins rotating speed again, when temperature of charge in the high-speed mixer is 75-80 ℃, stop to stir;
Step 2, get 7-9 parts of fire retardants and 14-16 parts of carbon blacks respectively, fire retardant and carbon black are added in the material of step 1, stir with 500-700 rev/mins rotating speeds, after material temperature in the high-speed mixer is 85-90 ℃, stop to stir, make material be cooled to 50-60 ℃ naturally;
Step 3, the material in the step 2 is put into tablet machine, when material is heated to 150-160 ℃, carry out granulation, make granularity and be the plastics soft formation granule of 3-5mm, standby;
Step 4, be wrapped in steel wire on the mould and be put in the die inlet end of extruder, the plastics soft formation granule that with granularity in the step 3 is 3-5mm is then sent in the extruder, making mould and plastics soft formation granule simultaneously is 170-180 ℃ extruder through excess temperature, extrusion modling makes product.
Beneficial effect
The invention has the beneficial effects as follows: the present invention adopts PVC as raw material, add anti-static agent and fire retardant then, the PE pipe, hard tube and the polyethylene pipe that solve in the past scarcely possess fire-retardant and anlistatig effect, and mine in the present invention is 10 with the surface resistance of plastic hose
6Europe rice is lighted the mine of producing with plastic hose, extinguish naturally lighting in back 3 seconds, shows that mine has good antistatic and fire retardation with flexible pipe.
Add dibutyl phthalate (Dibutyl phthalate among the present invention, DBP) as plasticizing agent, because dibutyl phthalate self is easy to generate static, generally be not suitable for the equipment of gas extraction under the colliery, yet add carbon black in the present invention, carbon black belongs to antistatic inorganic material, have good elasticity, toughness and excellent conducting performance, make the product of formation not only have anlistatig effect but also increased toughness, elasticity, color and luster and the glossiness of product again, therefore guaranteed the safe handling of dibutyl phthalate fully.Chlorinated paraffin-52 is as a kind of secondary plasticizer and fire retardant, secondary plasticizer mainly as PVC, therefore in the present invention with dibutyl phthalate, chlorinated polyvinyl chloride paraffin-52 and carbon black mixing use, not only solve the problem that product easily produces static, and increased the flame retardant property of product, and improve the flame retardant effect of product, also increase the pliability and the extensibility of product simultaneously, save production cost, improve productivity effect.
Mine of the present invention is inlayed steel wire with plastic hose in pipe, be that flexible pipe has good elasticity and toughness, add stearic acid in the present invention, can increase pliability, elasticity and the tortuosity of plastic hose, increase the radius of plastic hose bent axle, make plastic hose better be applicable to operation under the mine, make the connection between plastic hose tightr, do not have the slit, reduce gas leakage, guarantee the safety of staff under the mine, enhance productivity.
The present invention is used to prepare the method for mine with plastic hose, by add raw material in batches in the high-speed mixing process, makes the abundant combination of each raw material components, and interacting provides pliability, electric conductivity and the non-flame property of flexible pipe.Stirring by high-speed mixer produces heat energy, reduces energy consumption, saves production cost, enhance productivity, and the simple easy operating of preparation method, with low cost, be convenient to promote.
