Technical field

The present invention relates to pipe technology, in particular to a kind of house ornamentation multiple tube.

Background technique

Modern house ornamentation increasingly pays close attention to the safety of pipeline hidden installing engineering, comfort and energy-saving effect.Than Such as, the heat preservation energy-saving of daily hot water pipeline, winter pipeline frost crack preventing bursting by freezing；Southern summer high-temperature, high humidity environment pipeline are anti-" cold It is solidifying ", all there is an urgent need to the development and application of heat-preserving composite pipeline.Under some furred ceilings and outdoor bright dress operating condition, it is desirable that pipeline is same When also there is weatherability, scratch-resistant and rigidity.Traditional insulating rubber plastic and installation method, there is also some defects: 1, Scene suit construction is inconvenient, and fitting is caused not influence heat insulation effect closely；2, rubber-plastics material heat insulation effect easy to moisture absorption is poor, is easy Aging service life is short；3, surface does not have protective layer, is easy to scratch when through walls.

The Chinese invention patent of Patent No. ZL201611183366.2 disclose a kind of house ornamentation PPR composite insulating pipe and Preparation method, house ornamentation PPR composite insulating pipe are three-layer composite structure, pass through on PPR or the plastic-aluminum combined inner tube layer of PPR Equipment is coated with polyethylene foamed insulating layer, is coated in polyethylene foamed heat preservation middle layer by extruder and is protected outside weather-proof scratch-resistant Layer, polyethylene foamed insulating layer use closed cell foamed material, abscess-size 0.2-0.5mm, PPR or PPR aluminum plastic composite pipe The outer diameter of internal layer is more than or equal to 16mm, and thickness is more than or equal to 2.3mm, and the polyethylene foamed insulation layer thickness is more than or equal to 5mm, the weather-proof scratch-resistant outer layer thickness are more than or equal to 0.2mm.It is easily deformed with solving not scratch-resistant, insulating layer, is easily old The problems such as change, and then improve the heat insulation effect of pipeline, extend the service life of pipeline, improve the safety of family's pipeline.

The house ornamentation of above-mentioned patent disclosure PPR composite insulating pipe, mainly passing through solution, scratch-resistant, insulating layer are not easy to become The problem of heat insulation effect caused by shape and aging is deteriorated, rather than improved in terms of the thermal insulation property for improving insulating layer itself Design, therefore its heat insulation effect is still to be improved.

Summary of the invention

The technical problems to be solved by the present invention are: providing a kind of house ornamentation multiple tube, house ornamentation multiple tube can further improve Heat insulation effect.

In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows:

A kind of house ornamentation multiple tube, including the hollow tube, insulating layer and protective layer set gradually from the inside to the outside, the heat preservation Layer prepares raw material including following parts by weight content: 50-60 parts of diatomite, 10-15 parts of vermiculite power, waterborne polyurethane resin 20- 30 parts, 5-10 parts of magnesia, 5-10 parts of carboxymethyl cellulose, 3-8 parts of hollow glass micropearl and 5-8 parts of foaming agent.

The beneficial effects of the present invention are:

House ornamentation multiple tube of the invention can be obtained lower thermally conductive by the specific raw material proportioning of the above-mentioned insulating layer of design Coefficient, to improve the thermal insulation property of insulating layer itself, so that whole house ornamentation multiple tube obtains preferable heat insulation effect.

Detailed description of the invention

Fig. 1 is the transverse sectional view of the house ornamentation multiple tube of the embodiment of the present invention.

Label declaration:

1, hollow tube；2, insulating layer；3, protective layer.

Specific embodiment

To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached Figure is explained.

The most critical design of the present invention is: designing the concrete component and ratio of above-mentioned insulating layer, obtain lower thermally conductive Coefficient.

Please refer to Fig. 1, a kind of house ornamentation multiple tube, including the hollow tube 1, insulating layer 2 and guarantor set gradually from the inside to the outside Sheath 3, the insulating layer 2 prepare raw material including following parts by weight content: 50-60 parts of diatomite, 10-15 parts of vermiculite power, water Property 20-30 parts of polyurethane resin, 5-10 parts of magnesia, 5-10 parts of carboxymethyl cellulose, 3-8 parts of hollow glass micropearl and foaming agent 5-8 parts.

As can be seen from the above description, the beneficial effects of the present invention are:

House ornamentation multiple tube of the invention can be obtained lower thermally conductive by the specific raw material proportioning of the above-mentioned insulating layer of design Coefficient, to improve the thermal insulation property of insulating layer itself, so that whole house ornamentation multiple tube obtains preferable heat insulation effect.

Further, the granularity of the diatomite, vermiculite power, magnesia, carboxymethyl cellulose and foaming agent is 100- 2000 mesh.

Further, the partial size of the hollow glass micropearl is 10-20 μm.

Seen from the above description, can control hollow glass micropearl partial size be 10-20 μm, it is preferred that glass microballoon it is strong Degree is greater than or equal to 20MPa.

Further, the protective layer is galvanized sheet or aluminium alloy plate.

Further, the material of the hollow tube is PPR.

Further, PIR layers are additionally provided between the insulating layer and protective layer.

Seen from the above description, add it is PIR layers above-mentioned, due to PIR have thermal coefficient low (0.019-0.021W/m.K), Good heat-insulating property, more preferably than PU flame retardant property, rate of closed hole more higher than PU and smaller water absorption rate therefore can be with Further promote the integral heat insulation performance of house ornamentation multiple tube.

Further, the ratio of the hollow tube, insulating layer, protective layer and PIR layers of thickness is (1-10): (2-5): (6-8): (2-3).

Seen from the above description, can according to demand to above-mentioned hollow tube, insulating layer, protective layer and PIR layers of thickness into Row selection design, it is preferred that, can when above-mentioned hollow tube, insulating layer, protective layer and PIR layer choosing select the ratio of above-mentioned thickness Have the advantages that measured thermal insulation property and cost consumption low as far as possible to the greatest extent to obtain to take into account.

Referring to Figure 1, the embodiment of the present invention is as follows:
