Abstract
The invention discloses an anti-leakage double-wall corrugated pipe. The anti-leakage double-wall corrugated pipe is prepared from the following raw materials in parts by weight: 75-80 parts of pvc (Polyvinyl Chloride) resin, 3-4 parts of polybenzimidazole fiber, 0.6-2 parts of black sand, 0.7-1 part of permethrin, 1-2 parts of boric acid, 2-3 parts of butyl polyacrylate, 0.3-0.5 parts of sodium carboxymethyl cellulose, 0.1-0.3 parts of ethylene glycol monobutyl ether, 2-3 parts of ethylene bis stearamide, 2-4 parts of vermiculite powder, 1-2 parts of calcium aluminate and 6-10 parts of compound filler. The corrugated pipe disclosed by the invention is flame-resistant, soft, light, and excellent in corrosion resistance and leakage resistance.
Description
Technical field
The present invention relates generally to a kind of tubing, relates in particular to a kind of anti-leakage double-wall corrugated pipe.
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.
Summary of the invention
The object of the invention is just to provide a kind of anti-leakage double-wall corrugated pipe.
The present invention is achieved by the following technical solutions:
A double-wall corrugated pipe, it is comprised of the raw material of following weight parts:

Described compounded mix is comprised of the raw material of following weight parts:
Laterite 26-30, medical stone powder 10-20, rosin 4-5, calcium acetylacetonate 0.8-2, aluminium nitride 1-2, hexagonal boron nitride 2-3, propolis 1-2;
Above-mentioned laterite is calcined to 2-3 hour at 700-900 ℃, after discharging is cooling, mix with aluminium nitride, hexagonal boron nitride, grind, obtain powder; To after above-mentioned rosin heating fusing, mix insulated and stirred reaction 1-2 hour at 120-150 ℃, the cooling rear ball milling mixing 20-30 minute of discharging with medical stone powder, calcium acetylacetonate, propolis, add powder obtained above, fully ball milling, crosses 80-120 mesh sieve, obtains described compounded mix.
A preparation method for anti-leakage double-wall corrugated pipe, comprises the following steps:
Above-mentioned Xylo-Mucine is joined in 5-10 times of water, be heated to 50-60 ℃, after stirring, add vermiculite power, polybenzimidazole fibre, be stirred to water dry, add each raw material of residue, at 120-140 ℃ of temperature, stir, automatically cooling after stirring, after vibratory screening apparatus, automatic charging, is extruded through High Temperature High Pressure by twin screw extruder, after forming machine is pulled out product, by cutting machine fixed length cutting, send into pipe-expanding machine, packing warehouse-in after enlarging completes.
Advantage of the present invention is:
Corrugated tube difficulty of the present invention is fired, softness is light, anticorrosive, leakage resistance is superior.
