Description

A kind of rare earth corrugated tube

Technical field

The present invention relates generally to a kind of tubing, relates in particular to a kind of rare earth 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 rare earth 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:

High density polyethylene(HDPE) 93-100, lanthanum trioxide 0.4-0.6, bis-phenol a diglycidylether 1-2, Lauryl Alcohol ester 2-4, gibbsite 2-3, palm wax 3-4, Seignette salt 0.6-1, Tetrabutyl amonium bromide 0.3-0.5, copper naphthenate 1-2, pamorusa oil 1-2,1,2 dimethylimidazole 0.5-1, compounded mix 5-10;

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 rare earth corrugated tube, comprises the following steps:

Above-mentioned each raw material is mixed, 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 of the present invention has very high mechanical property and friction resistant performance, and thermostability and weathering resistance are strong, and over-all properties is outstanding, is widely used.
