Abstract
The invention discloses a low-temperature impact-resistant tubular product, which is characterized by being composed of the following raw materials in parts by weight: 70-76 parts of polyethylene GF7750, 4-6 parts of drying oil alkyd resin, 2-3 parts of ethylene-octene copolymer, 1-2 parts of diacetone alcohol, 0.7-2 parts of triclosan, 2-3 parts of polyimide, 3-4 parts of di(2-ethylhexyl)-epoxy tetrahydrophthalate, 2-3 parts of carbon fibers, 3-4 parts of illite powder, 2-3 parts of aluminum stearate and 5-7 parts of composite filler. The PE pipe provided by the invention is prepared from recycled polyethylene material so that the production cost is reduced and resources are saved; the tubular product provided by the invention has excellent low-temperature impact resistance; for construction in winter, pipe breakage is avoided; the low-temperature impact-resistant tubular product also has high shear strength and excellent scratch resistance.
Description
Technical field
The present invention relates generally to a kind of tubing, relates in particular to a kind of low temperature impact tubing.
Background technology
Pvc pipe (UPVC pipe) hard polvinyl choride pipe, is to use pressure sintering extrusion molding after being coordinated with stablizer, lubricant etc. by polyvinyl chloride (PVC) RESINS, is the plastic pipe being developed and applied the earliest.UPVC pipe resistance to corrosion is strong, it is bonding to be easy to, price is low, quality is hard, but owing to having UPVC monomer and additive exudation, is only applicable in water feeding system that delivery temperature is no more than 45 ℃.Plastic conduit is for delivery of tap water, waste water, chemical, heating fluid and cooling fluid, food, ultrarapture liquid, mud, gas, the application of pressurized air and vacuum system.
PE pipe has medium-density polyethylene pipe and high density polyethylene pipe.The former is applicable to carry artificial coal gas, Sweet natural gas, the liquefied petroleum gas (LPG) of gaseous state, and the latter is mainly for delivery of Sweet natural gas.With steel pipe comparison, construction technology is simple, has certain snappiness, and main is to be not used as rotproofing, will save a large amount of operations.Shortcoming is with regard to apparatus not as steel pipe, and the special safe spacing of noting heating power heating in construction, and can not being exposed in air under sunlight, and responsive to chemical substance, prevents that the leakage of sewer line from damaging.
Summary of the invention
The object of the invention is just to provide a kind of low temperature impact tubing.
The present invention is achieved by the following technical solutions:
A tubing, it is comprised of the raw material of following weight parts:
Polyethylene GF7750 70-76, drying oil alkyd resin 4-6, ethylene-octene copolymer 2-3, diacetone alcohol 1-2, triclosan 0.7-2, polyimide 2-3, epoxy tetrahydro-2-ethylhexyl phthalate 3-4, the stone flour 3-4 of carbon fiber 2-3, Erie, aluminum stearate 2-3, compounded mix 5-7;
Described compounded mix is comprised of the raw material of following weight parts:
Chrysotile 30-40, gibbsite 10-15, chromium carbonate 3-5, ricinolic acid 1-2, aluminium hydroxide 1-2, methacrylic acid-2-hydroxy methacrylate 2-3, glyceryl monostearate 4-5,
linking agent TAC1-2,butyl polyacrylate 2.5-4, irgasfos 168 0.4-1;
By gibbsite and chrysotile, chromium carbonate mix and blend, pulverize, add ricinolic acid, 400-600 rev/min of dispersed with stirring 3-5 minute, add aluminium hydroxide, butyl polyacrylate, at 100-160 ℃, insulated and stirred 40-50 minute, is cooled to normal temperature, adds each raw material of residue, fully stir, dry, granulation, particle diameter is 2-4 μ m.
A preparation method for low temperature impact tubing, comprises the following steps:
Above-mentioned each raw material is mixed, send into kneader, at 70-80 ℃, mediate, discharging is cooled to normal temperature, melt extrudes, and cooling, moulding obtains described low temperature impact tubing.
Advantage of the present invention is:
Tubing of the present invention has good low-temperature impact resistance, while constructing in the winter time, tube brakes can not occur, and also has high shearing resistance and excellent anti-scratch trace ability.
