Abstract

The utility model discloses a heat-resisting polyethylene cold and hot water pipe which is formed by an outer layer pipe and an inner layer pipe in an extruding composite mode. The inner layer pipe is wrapped inside the outer layer pipe. The thickness of the inner layer pipe is 1.5-2.5mm, and the thickness of the outer layer pipe is 2.2-3.0mm. A nano silver ion antibacterial agent is added in the inner layer pipe, and an antioxidant is added in the outer layer pipe. The heat-resisting polyethylene cold and hot water pipe has the excellent advantages of being strong in frost resistance and thermal resistance, high in shock strength, high in toughness, safe and sanitary, capable of being welded, free of leakage in the system, safe and reliable.

Description

The heat-proof polythene cool and hot water pipe

Technical field

The utility model relates to a kind of pipe fitting, especially a kind of heat-proof polythene cool and hot water pipe.

Background technique

PE-RT (heat-resisting enhancement mode polyethylene) is a kind of polyene family thermoplastic plastic, and its density and other thermoplastics are basic identical.The PE-RT resin is the special copolymer of ethene and a small amount of octene, carries out side chain distribution control by MOLECULE DESIGN and obtains distinctive molecular structure.To be the PE-RT raw material form through hot melt extrusion molding, injection moulding cooling for PE-RT tubing, pipe fitting, not only processing technology is simple and also processing in influence factor to pipe workpiece quality few, pipe performance is mainly provided by raw material self, the reliability of quality of product is than higher.The PE-RT pipe-line system has outstanding compressive resistance cracking behavior and good long-term isostatic pressing strength, can be widely used in industry and civilian hot and cold water, potable water conveying and fields such as floor heating and radiator heating.

Yet the underground various service conduit transportation networks of arranging in cities and towns are more and more abundanter, therefore, have oxidation resistance, and degerming ability, the pipe structure of long service life are the main developing direction of tubing from now on.

The model utility content

The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of heat-proof polythene cool and hot water pipe, and it is short to be used for solving the working life that the existing cool and hot water pipe oxidation resistance of prior art difference causes, does not have the problem of degerming ability.

For achieving the above object, of the present utility modelly provide a kind of heat-proof polythene cool and hot water pipe, by external pipe be coated on its inner inner tube and extrude compound molding, the thickness of described inner tube is 1.5～2.5mm, be added with the nano silver ion antibiotic agent in the described inner tube, the thickness of described external pipe is 2.2～3.0mm, also is added with antioxidant in the described external pipe.。

Preferably, described external pipe, inner tube adopt the ethene copolymer material rare with suffering.

As mentioned above, a kind of heat-proof polythene cool and hot water pipe of the present utility model, it has possessed superpower temperature tolerance, and lasting anti-hydrostatic intensity and good shock resistance intensity of wave are widely used in having the various applied environments of high temperature requirement, have following beneficial effect:

1, freeze proof heat resistance is strong: under-20 ℃ situation, have the good low-temperature shock resistance, tubing can bursting by freezing, and after thawing, tubing can recover former state, can anti-high temperature below 110 ℃;

2, excellent in cushion effect, the toughness height: add antioxidant, make the tubing long service life, and elongation at break superelevation 500%, very strong to the adaptive capacity of uneven settlement and dislocation, shock resistance is good;

3, safety and sanitary: add the nano silver ion antibiotic agent, can come by the slow release of silver ion water body is carried out sterilizing, avoid breed bacteria in water pipe;

4, weldability: system does not leak, and is safe and reliable.

Embodiment

Below by specific instantiation mode of execution of the present utility model is described, those skilled in the art can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.The utility model can also be implemented or be used by other different embodiment, and the every details in this specification also can be based on different viewpoints and application, carries out various modifications or change under the spirit of the present utility model not deviating from.

Need to prove, the structure that illustrates in this Figure of description, ratio, size etc., equal contents in order to cooperate specification to disclose only, understand and reading for person skilled in the art scholar, be not in order to limit the enforceable qualifications of the utility model, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not influencing under the effect that the utility model can produce and the purpose that can reach, all should still drop in the scope that technology contents that the utility model discloses contains.Simultaneously, quote in this specification as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under no essence change technology contents, when also being considered as the enforceable category of the utility model.

Please in conjunction with shown in Figure 1, a kind of heat-proof polythene cool and hot water pipe structural representation that it provides for the utility model, it is by having external pipe 1 and inner tube 2 to extrude compound molding, it is material that described external pipe 1 and inner tube 2 adopt the rare copolymer of ethene and suffering, be added with the nano silver ion antibiotic agent in the described inner tube 2, be added with antioxidant in the described external pipe 1, the thickness of described inner tube 2 is 1.5～2.5mm, the thickness of described external pipe 2 is 2.2～3.0mm, wherein, the polymerized ethylene content difference that inner tube 1 contains, select different polyethylene proportionings to improve rigidity and the toughness of tubing as required, thereby improve the performance of the high temperature resistant and low temperature of tubing, and in inner tube 2 materials, added the nano silver ion antibiotic agent, therefore can come by the slow release of silver ion water body is carried out sterilizing.In external pipe 1 material, add antioxidant, further strengthened the oxidation resistance of tubing, thereby increased the working life of tubing.

Heat-proof polythene cool and hot water pipe forming process is as follows: the extruder automatic charging,, extrude through the extrusion molding nozzle, through vacuum sizing the fusion of tubing plastic pellet through the extrusion molding board, then adopt the water-bath cooling, become pipe to batch, cover the band traction, online sign is printed, and air-dry end product quality detects, and packing is finished finished product.

A kind of heat-proof polythene cool and hot water pipe of the present utility model, have following beneficial effect: freeze proof heat resistance is strong, under-20 ℃ situation, have the good low-temperature shock resistance, pipe fitting can bursting by freezing, after thawing, tubing can recover former state, can anti-high temperature below 110 ℃; Excellent in cushion effect, the toughness height adds antioxidant, makes the tubing long service life, and elongation at break superelevation 500%, and very strong to the adaptive capacity of uneven settlement and dislocation, shock resistance is good; The nano silver ion antibiotic agent is added in safety and sanitary, can come by the slow release of silver ion water body is carried out sterilizing, avoids breed bacteria in water pipe; Weldability, system does not leak, and is safe and reliable.So the utility model has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
