Abstract
The invention discloses a cold-resistant plastic tube comprising an outer tube and an inner tube. The outer tube and the inner tube are of a hollow cylinder structure, the outer tube is a plastic tube, and the inner tube is a metal tube. The outer surface of the inner tube is sleeved with the outer tube, the space between the outer tube and the inner tube is filled with fillings of a hollow cylinder structure, and a resin layer is further attached to the outer surface of the outer tube and made of acrylic resin. According to the cold-resistant plastic tube, the metal tube is adopted as the inner tube to ensure that the cold-resistant plastic tube is high in pressure-resistant performance, fillings are arranged between the inner tube and the outer tube, and the resin layer is further attached to the outer surface of the outer tube, so that the plastic tube is good in warm-keeping and cold-resistant performance and not prone to frost crack in air of cold weather.
Description
Technical field
The present invention relates to the field of plastic article, particularly relate to a kind of cold-resistant plastic pipe.
Background technique
Plastic tube does not comprise tube body, and in prior art, plastic tube is the structure of individual layer mostly, although have good corrosion resistance and the feature such as lightweight, flexible, bearing power is poor, and wear-resistant and be not incubated easily bursting by freezing in the situation that of cold weather.For the double layer construction that is designed to being incubated, between internal layer and skin, there is link to connect, between internal layer and skin, there is space, such plastic tube heat insulation effect is unsatisfactory.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of cold-resistant plastic pipe, inner tube adopts metal tube to guarantee to have higher withstand voltage properties, between outer tube and inner tube, there is packing, and on the outer surface of outer tube, be also attached with one deck resin layer, make the cold-resistant performance of insulation that plastic tube is good, in the air of cold weather, be difficult for by bursting by freezing.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of cold-resistant plastic pipe is provided, comprise outer tube and inner tube, described outer tube and inner tube are hollow cylindrical structure, described outer tube is plastic tube, described inner tube is metal tube, described outer tube sleeve is at the outer surface of inner tube, between outer tube and inner tube, be filled with packing, described packing is also hollow cylindrical structure, on the outer surface of described outer tube, be also attached with one deck resin layer, described resin layer adopts acrylic resin.
In a preferred embodiment of the present invention, the diameter of described outer tube is 6-8cm.
In a preferred embodiment of the present invention, the diameter of described inner tube is 3-5cm.
In a preferred embodiment of the present invention, described packing adopts foam or plastic materials.
In a preferred embodiment of the present invention, the thickness of described resin layer is 0.1-0.2mm.
The invention has the beneficial effects as follows: cold-resistant plastic pipe of the present invention, inner tube adopts metal tube to guarantee to have higher withstand voltage properties, between outer tube and inner tube, there is packing, and on the outer surface of outer tube, be also attached with one deck resin layer, make the cold-resistant performance of insulation that plastic tube is good, in the air of cold weather, be difficult for by bursting by freezing.
Brief description of the drawings
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of cold-resistant plastic pipe one preferred embodiment of the present invention;
Being labeled as in accompanying drawing: 1, outer tube, 2, inner tube, 3, packing, 4, resin layer.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention comprises:
A kind of cold-resistant plastic pipe, comprise outer tube 1 and inner tube 2, described outer tube 1 and inner tube 2 are hollow cylindrical structure, described outer tube 1 is plastic tube, and described inner tube 2 is metal tube, and described outer tube 1 is enclosed within the outer surface of inner tube 2, between outer tube 1 and inner tube 2, be filled with packing 3, described packing 3 is also hollow cylindrical structure, is also attached with one deck resin layer 4 on the outer surface of described outer tube 1, and described resin layer 4 adopts acrylic resin.
Acrylic resin is the resin of being made up of esters of acrylic acid and methyl acrylic ester and other olefinic type monomers copolymerization, by selecting different resin structures, different formula, production technology and solvent composition, the acrylic resin that can synthesize dissimilar, different performance and different application occasion, acrylic resin can be divided into again thermoplastic acrylic resin and thermosetting acrylic resin according to the difference of structure and membrane formation mechanism.With the acrylic resin of acrylate and methacrylate monomers copolymerization to the main absworption peak of light outside solar spectrum scope, so the acrylic resin paint making has excellent light fastness and anti-outdoor aging performance.
In above-mentioned, described outer tube 1 is plastic tube, and described inner tube 2 is metal tube, and described outer tube 1 is enclosed within the outer surface of inner tube 2.Wherein, the diameter of described outer tube 1 is 6-8cm; The diameter of described inner tube is 3-5cm, and inner tube adopts metal tube to guarantee to have higher withstand voltage properties.
Further, described packing 3 adopts foam or plastic materials, has the cold-resistant effect of insulation.
Further, on the outer surface of described outer tube 1, be also attached with one deck resin layer 4.Wherein, the thickness of described resin layer is 0.1-0.2mm, has light fastness and anti-outdoor aging performance, has further improved the cold-resistant effect of insulation of plastic tube.
The cold-resistant plastic pipe that the present invention discloses, inner tube adopts metal tube to guarantee to have higher withstand voltage properties, between outer tube and inner tube, there is packing, and on the outer surface of outer tube, be also attached with one deck resin layer, make the cold-resistant performance of insulation that plastic tube is good, in the air of cold weather, be difficult for by bursting by freezing.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
