Abstract
The invention discloses a low-noise corrugated pipe, which is characterized by being composed of the following raw materials in parts by weight: 60-64 parts of polypropylene random copolymer, 0.4-0.6 part of octabromoether, 1-2 parts of phosphite ester, 1-2 parts of butyl hydroxy anisd, 2-3 parts of azodiisobutyronitrile, 1-3 parts of aluminum triphosphate, 3-4 parts of quasi-spherical silica powder, 2-3 parts of diisopropylethanolamine, 1-2 parts of valerian oil, 3-4 parts of expanded perlite, 4-5 parts of hollow glass micro beads, 0.1-0.3 part of sodium methylene dinaphthalenesulfonate and 3-6 parts of composite filler. The low-noise corrugated pipe provided by the invention is excellent in low temperature resistance, impact resistance and creep resistance, long in service life and resistant to corrosion; the added expanded perlite and the hollow glass micro beads both are capable of achieving certain sound absorption effect.
Description
Technical field
The present invention relates generally to a kind of tubing, relates in particular to a kind of lower noise corrugated tube.
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 lower noise corrugated tube.
The present invention is achieved by the following technical solutions:
A corrugated tube, it is comprised of the raw material of following weight parts:
Atactic copolymerized polypropene 60-64, eight bromo ether 0.4-0.6, phosphorous acid ester 1-2, butylated hydroxy anisole 1-2, Diisopropyl azodicarboxylate 2-3, aluminium triphosphate 1-3, torispherical silicon powder 3-4, diisopropyl ethanolamine 2-3, valerian oil 1-2, pearlstone 3-4, hollow glass micropearl 4-5, sodium metnylene bis-naphthalene sulfonate 0.1-0.3, compounded mix 3-6;
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 lower noise corrugated tube, 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 lower noise corrugated tube.
Advantage of the present invention is:
Lower noise corrugated tube of the present invention has good anti-low temperature, shock resistance, creep resistance, and the life-span is long, corrosion-resistant, and the pearlstone adding and hollow glass micropearl can play certain sound-absorbing effect.
