Description
Technical field
The present invention relates to field of mechanical technique more particularly to a kind of preparation methods of non-excavation-use polythene drainpipe.
Background technique
PE pipe municipal tubing market Chinese at present, plastic conduit is just in stable development, and PE pipe, PP-R pipe, UPVC pipe are all
It occupies a tiny space, wherein PE manages powerful growth momentum and attracts people's attention the most.PE pipe municipal tubing market Chinese at present, modeling
Pipe material is just in stable development, and PE pipe, PP-R pipe, UPVC pipe all occupy a tiny space, and wherein PE manages powerful growth momentum most
To attract people's attention.PE pipe uses field extensive.Wherein feed pipe and fuel gas conduit are them
Two maximum application markets.PE resin is polymerized by monomer ethylene, due to polymerization when because of pressure, temperature
The polymeric reaction conditions such as degree are different, can obtain the resin of different densities, because and have high density polyethylene (HDPE), medium density polyethylene and
Point of low density polyethylene (LDPE).When processing different type PE tubing, according to the difference of its application conditions, resin grade is selected not
Together, the requirement while to extruder and mold is also different.
The material of polyethylene pipe is divided into five grades of PE32, PE40, PE63, PE80, PE100 in the world, and is used to fire
The material of tracheae and feed pipe is mainly PE80 and PE100.China is not classified Polyethylene Pipe Resin, this makes the country
Polyethylene gas pipe and feed pipe manufacturer selection raw material are relatively difficult, also bring to the use of polyvinyl piping materials not small
Hidden danger.
Therefore State Standard Bureau made in GB/T13663-2000 new standard a large amount of revision, it is specified that feed pipe not
Same level PE80 and PE100 correspond to the different intensities of pressure, and remove the tensile strength performance in old plant, and increase and resolve
Elongation (being greater than 350%) is split, that is, emphasizes basic toughness.Water supply is that traditional steel tubing, polyvinyl chloride are drunk with PE tubing
The regeneration product of water pipe.
Feed pipe must endure as certain pressure, usually select that molecular weight is big, PE resin of better mechanical property, such as
HDPE resin.The tensile strength of LDPE resin is low, resistance to pressure difference, poor rigidity, poor dimensional stability when processing and forming, and connects tired
Difficulty is not suitable for the material as feed pressure pipe.But since its sanitary index is higher, LDPE especially LLDPE resin is had become
Produce the common used material of drinking-water pipe.The melt viscosity of LDPE, LLDPE resin is small, good fluidity, easy processing, thus molten to it
The range of choice of body index is also wider, and usual MI is between 0.3-3g/10min.
Although there is the research for carrying out modifying plastics using compounded mix at present, the basic nature of tubing is seldom considered in research
Can and mechanical property, processing performance, the balance between compressive property, it is especially long-term quiet so as to cause polyvinyl piping materials performance
Hydraulic test is unable to reach the requirement of standard.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of non-excavation-use polyethylene proposed
The preparation method of drainpipe.
To achieve the goals above, present invention employs following technical solutions:
The preparation method of non-excavation-use polythene drainpipe, characterized by comprising the steps of: press following weight percent
Than a group distribution raw material: HDPE70%, activeness and quietness auxiliary agent 20%, glass fibre 5%, color masterbatch 3%, clear infusion 2%；
Preheating and drying: the various raw material preheatings prepared by predetermined ratio are dried in vacuum drying oven；
Mixed raw material: mixing device is used, the various raw materials prepared by predetermined ratio are stirred until homogeneous；
Extrusion molding: the raw material mixed is put into extruder, extruding pipe material；
Vacuum sizing: using vacuum machine to the tubing vacuum sizing of extrusion；
It is cooled and shaped: being cooled and shaped using tubing of the pipe cooler to extrusion molding, then using lift
Jet cutting machine is cut.
In the present invention, in use, clear infusion is added in measuring bottle operator, solid material is added in material barrel, is passed through
Electronic scale weighs the weight of raw material, then opens the switch of the first hydraulic cylinder, and the first hydraulic cylinder pushes parcel shelf overturning,
And then add raw materials into conically shaped, the valve of measuring bottle lower end is opened, clear infusion is added in conically shaped, driving motor is opened
Switch, driving motor rotation drive agitating device rotation, and then mix to raw material, the first paddle different in size and the
Two paddles keep mixing more abundant, and mixed raw material is transported on forced-feeding device by conveying feeding apparatus, is passed through
Forced-feeding device carries out feeding to conical double ribbon rasp bar extruder, and polythene drainpipe is made by extrusion die, then will
Polythene drainpipe is transported in spray vacuum shaping box and carries out shaping, and is cooled down after sizing by impregnating cooling water tank, so
Polythene drainpipe is cut by cutter lifting cutting machine afterwards.Structure of the invention design design is reasonable, easy to operate, polyethylene drainage
Tubing retains the extensive flexibility (adaptability) of operation of HDPE script, can carry out a plurality of types of plastic processings, and it is qualified that mechanical property is made
Different products, improve the compressive property of tubing；Polyethylene drainage tube preparation method is economical and practical, and is guaranteeing that tubing is whole
It under conditions of performance, reduces costs as far as possible, improves competitiveness.
