Abstract
The invention discloses an HDPE (high-density polyethylene) double-wall corrugated pipe with high ring stiffness. The HDPE double-wall corrugated pipe comprises the following raw materials in parts by weight: 47 to 49 parts of high-density polyethylene, 17 to 19 parts of high modulus propene polymer (PP), 3 to 5 parts of attapulgite, rigidity-reinforcing and tenacity-reinforcing master batch and the like. Due to the adoption of the formula of the HDPE double-wall corrugated pipe, the ring stiffness of the HDPE double-wall corrugated pipe can be greatly improved; due to the adoption of the attapulgite in the formula, the HDPE double-wall corrugated pipe has high water absorptivity and slurry making property; and due to the adoption of modified acrylic resin which has certain cohesiveness, the machining property is high.
Description
Technical field
The present invention relates to the corrugated tube preparing technical field, mainly is a kind of HDPE double-wall corrugated pipe of high ring rigidity, mainly is to improve the ring stiffness of present domestic HDPE double-wall corrugated pipe.
Background technology
Common in the market HDPE double-wall corrugated pipe ring stiffness is generally 4KN/M
2, 8KN/M
2, i.e. SN4 on the market, SN8 tubing, ring stiffness is lower; Can only satisfy general requirement of engineering, though the high rigidity tubing of PP in recent years appear on the relevant report, because of processing units, reasons such as raw material; Can't become the main flow in market always, be meeting the market requirement, my company is according to existing equipment; Introduce novel major-minor material, the optimization design prescription has been produced 12.5KN/M
2, 16KN/M
2Etc. high rigidity series tubing, satisfy the demand of present special engineering to pipe performance.
Summary of the invention
The HDPE double-wall corrugated pipe that the purpose of this invention is to provide a kind of high ring rigidity can increase substantially the ring stiffness of HDPE double-wall corrugated pipe, good processability.
In order to achieve the above object, the technical scheme that the present invention adopted is:
The HDPE double-wall corrugated pipe of high ring rigidity, it comprises the raw material of following weight ratio:
High density polyethylene(HDPE) 47-49

HDPE plasticizing mother particle 23-25
Polyester modification vinyl resin 3-5
Silicone-modified vinyl resin 1-3
ABS high glue powder 3-5
Acrylic ester impact-resisting modifier ACR 2-3
Colour batch 3-5.
The HDPE double-wall corrugated pipe of described high ring rigidity is characterized in that: said weight ratio is preferably:
High density polyethylene(HDPE) 48

Colour batch 4.
High ring rigidity HDPE double-wall corrugated pipe preparation flow of the present invention is following:
(1), batch mixing: each raw material is poured in the stirrer according to aforementioned proportion, material is mixed, arrive forcing machine through negative pressure transportation;
(2), plasticizing is extruded: the material that is mixed adds the hot shearing plasticizing through screw barrel and extrudes;
(3), mould molding: the molten materials of extruding is through undulator shaping pipe shape;
(4), tubing is accomplished through cutting and is checked to go at last stockyard.
This tubing is to be main raw material with the special-purpose HDPE resin of extrusion grade heavy caliber pipe, but the requirement that will prepare the equal National standard of each item performance index, its ring stiffness reaches 12.5KN/M especially
2, 16KN/M
2Index, the crucial prescription that just is to select and adjust compsn.
Beneficial effect of the present invention:
Adopt prescription of the present invention can increase substantially the ring stiffness of HDPE double-wall corrugated pipe, added attapulgite in the prescription and had strong absorptive and make the slurry performance, and acrylic resin modifiedly have certain cohesiveness, a good processability.
