Description
Technical field
The present invention relates generally to a kind of tubing, relates in particular to a kind of polyethylene water service 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.
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 polyethylene water service pipe.
The present invention is achieved by the following technical solutions:
A water service pipe, it is comprised of the raw material of following weight parts:
Polyethylene 8010 80-87, N-ethyl-adjacency pair toluol sulfonamide 1-2, potassium tetraborate 1-2, hexanodioic acid propanediol polyester 2-4, polyvinylidene difluoride (PVDF) 4-6, primary ammonium phosphate 1-2,6-ditertbutylparacresol 0.7-1, irgasfos 168 0.7-1, zirconium white 1-2, ethyl acetate 2-3, vanadium diboride 0.5-1, dimethyl sulfoxide (DMSO) 0.5-1, celestite powder 4-5, compounded mix 6-9;
Described compounded mix is comprised of the raw material of following weight parts:
Agalmatolite 20-24, attapulgite 10-16, jade 3-5, polydimethylsiloxane 0.6-1, two Imidurea 1-2, Oil of Eucalyptus 1-2, oxidized polyethlene wax 2-4;
Above-mentioned agalmatolite, attapulgite are mixed with jade, ball milling is even, adds oxidized polyethlene wax, insulated and stirred 3-6 minute at 80-120 ℃, reduction temperature is 40-50 ℃, add polydimethylsiloxane, 600-1000 rev/min of dispersed with stirring 10-13 minute, adds two Imidureas, Oil of Eucalyptus successively, abundant ball milling, granulation, particle diameter is 2-4 μ m, obtains described compounded mix.
A preparation method for polyethylene water service pipe, comprises the following steps:
Above-mentioned each raw material is mixed, carry out high-speed kneading mixing, mixing time is 10-13 minute, and rising temperature is 130-140 ℃, and being stirred to temperature is 40-50 ℃, melt extrudes, and cooling, moulding, obtains described polyethylene water service pipe.
Advantage of the present invention is:
Drawing pipe intensity of the present invention is high, and resistance to pressure is good, good rigidly, and during forming process, dimensional stabilizing is good, and connectivity is good.
