Abstract
The utility model relates to a composite heat-preserving hot water pipe, comprising a PPR (polypropylene-random) water pipe or a PU (polyurethane) water pipe, wherein the outer surface of the PPR water pipe or the PU water pipe is wrapped with a polyurethane foaming filling layer. In the composite heat-preserving hot water pipe provided by the utility model, the outer surface of a pipeline is wrapped with the polyurethane foaming filling layer, so that the heat-preserving effect is good, and the oil resistance, the wear resistance and toughness are strong and the service life is longer.
Description
Technical field
The utility model relates to the water pipe technical field, specifically is the complex heat-preservation hot-water line.
Background technique
The PPR water pipe that prior art provides, PU water pipe etc., all heat insulation effect is all bad, and not oil resistant, not wear-resisting, toughness is not strong, working life is not long.
The model utility content
Main purpose of the present utility model provides a kind of complex heat-preservation hot-water line of high insulating effect.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of complex heat-preservation hot-water line, it comprises: PPR water pipe or PU water pipe, the outer surface of described PPR water pipe or PU water pipe is enclosed with the polyurethane foam packed layer.
Preferably, described PPR water pipe or PU water pipe and described polyurethane foam packed layer are one-body molded.
Preferably, the thickness of described polyurethane foam packed layer is 10 millimeters.
Implement the technical solution of the utility model, have following beneficial effect: the complex heat-preservation hot-water line that the utility model provides is by the outer surface parcel one deck polyurethane foam packed layer at pipeline, have good heat insulation effect, and oil resistant, wear-resisting, toughness is strong, working life is longer.
Description of drawings
The structural representation of the complex heat-preservation hot-water line that Fig. 1 provides for the utility model embodiment
The realization of the utility model purpose, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model embodiment provides a kind of complex heat-preservation hot-water line, and as shown in Figure 1, this complex heat-preservation hot-water line comprises: PPR water pipe 101, in other embodiment, also can be PU water pipe etc., and described PPR water pipe 101 is wrapped with polyurethane foam packed layer 102.Improved the heat insulating ability of PPR water pipe or PU water pipe.And owing to polyurethane is the carbamate groups that is contained strong polarity by isocyanates (monomer) and hydroxy compounds polymerization, be insoluble to non-polar group, have good oil resistance, toughness, wear resistance, ageing resistance and adhesiveness.The material that adapts to wide temperature range (50～180 ℃) (be applicable to northern low temperature condition use, guarantee the temperature of water temperature) be can make with different material, elastomer, thermoplastic resin and thermosetting resin comprised.Hydrolysis resistance not under the high temperature, also alkali-proof medium not adopts the polyurethane foam packed layer, thickness reaches 10mm, improves the service life of PPR water pipe greatly, can guarantee and not damage in 10 years, indeformable, the complex heat-preservation water pipe adopts closed insulation, and water-fast temp effect can reach 180 ℃.
In a preferred embodiment, described PPR water pipe 101 and described polyurethane foam packed layer 102 are one-body molded.This complex heat-preservation hot-water line adopts large mold fixedly PPR water pipe or PU water pipe, adopts polyurethane to carry out computer than recompounding filling-foam, forms foam filled layer, thereby once-through has reduced the man-hour in artificial installation and the expenditure of cost.
Below only be preferred embodiment of the present utility model,, all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model not in order to restriction the utility model.
Claims (3)
1. a complex heat-preservation hot-water line is characterized in that, comprising: PPR water pipe or PU water pipe, the outer surface of described PPR water pipe or PU water pipe is enclosed with the polyurethane foam packed layer.
2. complex heat-preservation hot-water line according to claim 1 is characterized in that described PPR water pipe or PU water pipe and described polyurethane foam packed layer are one-body molded.
