Abstract
The invention discloses a PE (polyethylene) tube. The PE tube consists of the following components in parts by weight: 100 parts of PPR 30R, and 3 parts of color master batch. A preparation method of the PE tube comprises the following steps: weighing the components according to the proportions, sequentially adding the components into a mixer, mixing the components uniformly at 60-80 DEG C to obtain a mixture, and performing extrusion molding on the mixture by using a screw extruder, wherein during extrusion, the screw temperature is 56-66 DEG C, the barrel temperature is 150-165 DEG C, and the mold temperature is 170-180 DEG C; and performing cooling setting on a tube after extrusion by adopting a vacuum cooling sizing method, wherein the vacuum degree during cooling is 0.02-0.04MPa, and the cooling temperature is 13-18 DEG C. Compared with the prior art, the tube produced by the method disclosed by the invention under the condition of ensuring the strength has the advantage of smooth surface. The preparation method disclosed by the invention not only is simple and convenient in production process, but also enables the produced tube to be relatively high in quality.
Description
Technical field
The present invention relates to a kind of PE pipes and preparation method thereof, belong to tubing technical field.
Background technology
PE（Polyethylene）Due to its superior performance, it is widely used in feed pipe manufacture field.PE water-feeding pipes have
Excellent corrosion resistance, sanitation performance, pliability, lower temperature resistance and longer service life, energy consumption is low, resistance to water-flow
Little, simple installation is rapid, it has also become traditional water supply steel tube and PVC（Polyvinyl chloride）The ideal substitute of feed pipe.Often adopt at present
Tubing is produced as raw material with PPR 30R, due to the problem of technological parameter, intensity height cannot be produced all the time and surface is smooth
Tubing.
The content of the invention
The technical problem to be solved in the present invention is：A kind of PE pipe and preparation method thereof is provided, can produce intensity it is high and
The smooth tubing in surface, can overcome the deficiencies in the prior art.
Technical scheme：A kind of PE pipe, calculates by weight, and the PE pipes are by 100 parts of PPR 30R, color masterbatch 3
Part composition.
The preparation method of the PE pipes：First each component is weighed by the proportioning, and each component is put into successively in batch mixer,
It is well mixed at 60 DEG C -80 DEG C and obtains compound, compound screw extruder extrusion molding, in extrusion, screw rod temperature
Spend for 56 DEG C ~ 66 DEG C, barrel temperature is 150 DEG C ~ 165 DEG C, mold temperature is 170 DEG C ~ 180 DEG C；Using true after tube extrusion
But sizing method carries out cooling and shaping to air cooling to tubing, and vacuum is -0.02MPa ~ -0.04MPa during cooling, and chilling temperature is 13 DEG C
~18℃。
The invention has the beneficial effects as follows：Compared with prior art, the present invention is produced in the case of proof strength
Tubing also has the advantages that surface is smooth.Not only simple production process is convenient for the present invention, and the pipe workpiece quality produced compared with
It is high.
