Abstract
The utility model relates to a kind of UPVC drinking-water tubing, and it is followed successively by from the inside to the outside: UPVC pipe, stainless steel belt, refractory layer, inner restrictive coating and oversheath protection against rodents layer; Described refractory layer is that high temperature resistant heat insulation is cotton; Described inner restrictive coating is the pvc sheathing compound of method hot rolling on refractory layer.The good impact resistance of the utility model UPVC drinking-water tubing, softening temperature is high.
Description
Technical field
The utility model relates to a kind of UPVC tubing, is specifically related to a kind of high temperature resistant, shock proof UPVC drinking-water tubing.
Background technique
UPVC pipe be a kind of with PVC＝polyvinyl chloride (PVC) resin for raw material, the not plastic tube of plasticizer-containing, it possesses the performance of general PVC＝polyvinyl chloride, turn increase some excellent properties, comprise corrosion resistance and ductility is good, cause not plasticizer-containing, can produce the tubing of nontoxic level, thus be specially adapted to water supply network.In addition, because it is non-conductive, be thus not easy and acid, alkali or salt generation electrochemical reaction, so acid, alkali or salt are all difficult to corrode it, so do not need outer anti-corrosive coating and liner.
But UPVC tubing in use still can run into some problems, e.g., impact resistance is poor, and according to the dart drop impact test of GB/T5836.1-92 standard detection, in most cases, First Pass Yield is less than 50%; Softening temperature is low, is easy to heat distortion, in general can improve softening temperature by strengthening amount of filler, but this can make the impact resistance of tubing, tensile strength and toughness greatly reduce.
Model utility content
In order to solve the problem, the utility model provides a kind of good impact resistance, the UPVC drinking-water tubing that softening temperature is high.
The utility model adopts following technological scheme:
A kind of UPVC drinking-water tubing, it is followed successively by from the inside to the outside: UPVC pipe, stainless steel belt, refractory layer, inner restrictive coating and oversheath protection against rodents layer; Described refractory layer is that high temperature resistant heat insulation is cotton; Described inner restrictive coating is the pvc sheathing compound of method hot rolling on refractory layer.
Further, described stainless steel belt is that Stainless Steel Band Double wound is on UPVC pipe.
Further, described oversheath protection against rodents layer is the polyolefin protection against rodents protective cover material of method hot rolling on inner restrictive coating.
The beneficial effects of the utility model are: outside UPVC pipe, be wound around stainless steel belt, increase the impact resistance of tubing; Cover stainless steel belt by high temperature resistant heat insulation cotton, improve the softening temperature of tubing, and match with the good heat conductive performance of Stainless Steel Band, increase tubing further to the tolerance of heat; Outermost surface covers protection against rodents layer, and prevent tubing when provided underground, muroid and ant class are to the destruction of tubing.
Accompanying drawing explanation
Fig. 1 the utility model cross-sectional view.
Wherein, 1 UPVC pipe, 2 stainless steel belts, 3 refractory layers, 4 inner restrictive coatings, 5 oversheath protection against rodents layers.
Embodiment
Shown in composition graphs 1, a kind of UPVC drinking-water tubing, it is followed successively by from the inside to the outside: UPVC pipe 1, stainless steel belt 2, refractory layer 3, inner restrictive coating 4 and oversheath protection against rodents layer 5; Outside UPVC pipe 1, be wound around stainless steel belt, increase the impact resistance of tubing; Described refractory layer 3 is that high temperature resistant heat insulation is cotton; Preferably, described refractory layer 3 is that spun-glass insulation is cotton; Cover stainless steel belt 2 by high temperature resistant heat insulation cotton, improve the softening temperature of tubing, and match with the good heat conductive performance of Stainless Steel Band, increase tubing further to the tolerance of heat; Described inner restrictive coating 4 is that pvc sheathing compound method hot rolling is on refractory layer 3.Described stainless steel belt 2 is that Stainless Steel Band Double wound is on UPVC pipe 1.Described oversheath protection against rodents layer 5 is that polyolefin protection against rodents protective cover material method hot rolling is on inner restrictive coating 4, concrete, described oversheath protection against rodents layer 5 selects the model of Hebei Zhonglian Plastic Technology Development Co., Ltd. to be ZL1112-HS, this material is cylindrical particle, smooth surface, free from admixture, have the effects such as termite-proof, protection against rodents, tubing can be prevented when provided underground, and muroid and ant class are to the destruction of tubing.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in previous embodiment, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the utility model embodiment technological scheme.
