The present invention relates to a kind of push pipe, disclose a kind of HDPE shapings push pipe, it includes push pipe body, push pipe body includes internal layer, sandwich layer and the outer layer set from inside to outside, internal layer is identical with the material component of outer layer, mixed by 98.35% HDPE and 1.65% pigment, sandwich layer is mixed by 83% HDPE, 6% inorganic mineral and 11% thermoplastic elastomer (TPE).There is high ring rigidity by push pipe made from above-mentioned formula, the characteristics such as the inner wall coefficient of sliding friction is small, while there is damping, sound insulation.
Description
Technical field
The present invention relates to a kind of push pipe, more particularly to a kind of HDPE shaping push pipes.
Background technology
High density polyethylene (HDPE), English name are " High Density Polyethylene ", referred to as " HDPE ". HDPE
It is that a kind of crystallinity is high, nonpolar thermoplastic resin.The milky appearance of ortho states HDPE, in meagre section in a certain degree
It is translucent.PE has a characteristics of excellent resistance to most of lives and chemicals for industrial use, the non-hygroscopic and waterproof that has had
It is vapor permeability, available for packaging applicationss.HDPE has good electrical property, and particularly dielectric strength is high, is readily applicable to it
Electric wire.In there is fabulous impact resistance to high molecular weight grades, room temperature in addition under -40F low temperatures it is such.
HDPE pipes are traditional steel tubing, the regeneration product of polyvinyl chloride drinking-water pipe, its due to as hydraulic pressure solenoid,
Tensile strength height must is fulfilled for, high pressure, rigidity is high, the characteristic such as dimensional stability height during processing and forming, existing HDPE pipes
Performance, which still has, to have greater room for improvement.
The content of the invention
The present invention for the problem of performance existing for HDPE pipes has much room for improvement in the prior art, there is provided a kind of HDPE into
Type push pipe.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
HDPE is molded push pipe, including push pipe body, it is characterised in that internal layer that push pipe body includes setting from inside to outside,
The material component of sandwich layer and outer layer, internal layer and outer layer is identical, is mixed by 98.35% HDPE and 1.65% pigment,
Sandwich layer is mixed by 83% HDPE, 6% inorganic mineral and 11% thermoplastic elastomer (TPE), it is ensured that push pipe epipodium is firm
Degree, the inner wall coefficient of sliding friction is small, while has effects that damping, sound insulation, is effectively improved the performance of HDPE shaping push pipes.
Preferably, push pipe body is formed and protected up to 55 through chromium plating process, Rockwell hardness by internal layer, sandwich layer and outer layer
Shield, and die face caustic dip, and in the hard steel mould through oil spraying or siliceous spray uniform fusion co-extrusion and formed, ensure stream
Body resistance is small, makes ectonexine and sandwich layer uniform fusion, and technique is simple, reliable in quality, equipment damage are small.
Preferably, the pigment includes 0.5% yellow uitramarine, 0.1% red pigment, 1% blue pigment with
And 0.05% charcoal blacks.
Be 0.4-0.6mm preferably, internal layer is identical with the wall thickness of outer layer, the wall thickness of sandwich layer for 1.9-2.4mm and
The density of sandwich layer is 1.2-1.8g/cm3。
The present invention has significant technique effect as a result of above technical scheme：
The present invention is designed to the easily molded push pipes of HDPE using this kind formula so that mixed material is easy into conventional processing temperature
Type, and improve the characteristics such as the ring stiffness of push pipe, high temperature resistant, proof to external pressure, product structure, sandwich layer fill process are optimized, has and subtracts
Shake, sound insulation effect so that product has more core competitiveness.
