Abstract
The invention discloses a high-density polyethylene double-layer water supply pipe which comprises an inner layer and an outer layer, wherein the inner layer is mainly prepared from the following raw materials by weight: 70-88 kg of high-density polyethylene, 5-15 kg of a rigidity and toughness increasing additive, and 5-15 kg of a compatibilizer. High-density polyethylene and the additive are selected to be specifically proportioned, so that the prepared high-density polyethylene double-layer water supply pipe has higher toughness and rigidity at the same time.
Description
Technical field
The present invention relates to water supply tubing, be specifically related to the double-deck supply pipe of a kind of high density polyethylene (HDPE).
Background technique
Current domestic urbanite water consumption supply uses tubing usually to have iron pipe, Stainless Steel Tube, PE pipe etc.Wherein iron pipe easily gets rusty, and is unfavorable for water cleaning; Stainless Steel Tube then high cost is not easy to promote.Although PE pipe then have not easily get rusty, lower-cost advantage, but still to have the following disadvantages: 1) fragility is comparatively strong, and resistance to torsion is low, if by easy bending deflection during larger rigid impulse or fracture; 2) thermal expansion coefficient is comparatively large, seriously influenced by ambient temperature, is too high or too low for temperaturely very easily out of shape, and the life-span is short; 3) anti-uv-ray is poor, and tube wall easily occurs the phenomenons such as aging, and has combustibility, and using scope is restricted.
HDPE (HighDensityPolyethylene, high density polyethylene (HDPE)) the double-deck supply pipe of high density polyethylene (HDPE) is one waterpipe emerging at present, there is excellent resistance to great majority life and the characteristic of chemicals for industrial use, be widely used in, in the plumbing fields such as highway, railway, greening, urban water supply and sewerage and subirrigation, becoming the update product of tradition water pipe.
At present in supply pipe field, the proportioning consumption of high density polyethylene (HDPE) and various auxiliary agent directly can have influence on the performances such as the strength of materials of supply pipe finished product, rigidity, modulus and heat resistance, cannot obtain gratifying effect.The polyethylene mixture of some formula is especially while raising plastics toughness, and the strength of materials, rigidity, modulus and heat resistance but decline to a great extent, and cannot reach the target of activeness and quietness and raising temperature classification simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of double-deck supply pipe of high density polyethylene (HDPE) simultaneously with higher toughness and higher-strength.
The double-deck supply pipe of high density polyethylene (HDPE) of the present invention, comprise internal layer and skin, described internal layer is made primarily of the raw material of following weight proportioning:
High density polyethylene (HDPE) 70 ~ 88, increase firm toughening auxiliary agent 5 ~ 15, compatibilizer 5 ~ 15.
In technique scheme, described high density polyethylene (HDPE) is PE100 level high-density polyethylene.The firm toughening auxiliary agent of described increasing can be that organic or inorganic material increases firm toughening auxiliary agent, and it can be zine oxide that described inorganic material increases firm toughening auxiliary agent.Described compatibilizer is polypropylene grafted maleic anhydride.
The skin of the double-deck supply pipe of high density polyethylene (HDPE) of the present invention is made primarily of the raw material of following weight proportioning:
High density polyethylene (HDPE) 70 ~ 88, increase firm toughening auxiliary agent 5 ~ 15, compatibilizer 5 ~ 15, antioxidant 3 ~ 10, look mother 3 ~ 5.
In above-mentioned outer field formula, described high density polyethylene (HDPE) is PE100 level high-density polyethylene.The firm toughening auxiliary agent of described increasing can be that organic or inorganic material increases firm toughening auxiliary agent, and it can be zine oxide that described inorganic material increases firm toughening auxiliary agent.Described compatibilizer is polypropylene grafted maleic anhydride.Described antioxidant is expandable polystyrene.Described color masterbatch is containing carbon black material.
The preparation method of the double-deck supply pipe of high density polyethylene (HDPE) of the present invention is same as the prior art.
Compared with prior art, the present invention selects high density polyethylene (HDPE) and auxiliary agent to carry out specific proportioning, makes the double-deck supply pipe of high density polyethylene (HDPE) obtained have higher toughness and higher intensity simultaneously.When the specification of obtained tubing is within the scope of national regulations (110.0≤external diameter≤111.0,5.3≤wall thickness≤6.1), its technical order as described in Table 1.
