Abstract
A fabric non-crosslinking heat-proof polyethylene three-layer multiple tubes, which is characterized in that glass fiber blanket and grammite fabric and the pipe wall middle layer(3) of the non-crosslinking heat-proof polyethylene multiple material are arranged between the pipe wall outer layer(1) of the non-crosslinking heat-proof polyethylene and the pipe wall inner layer(2). The utility model has the advantages that the intensity and the fire-resisting property are improved, and the expansion coefficient can reduce to one third of that of the non-crosslinking heat-proof polyethylene pipe. Comparing with the PP-R pipe, the low temperature resistance substantially improves, even in the low temperature of -20 DEG C, the tube is not damaged for brittleness. The utility model is applicable to architecture field hot-and-cold water duct system and other industrial duct system.
Description
(1) technical field
The utility model relates to a kind of compound plastic pipe, particularly relates to a kind of fiber/non-crosslinked heat-proof polythene composite pipe.
(2) background technique
From 2002, a kind of non-crosslinked heat-proof polythene (PE-RT) material of being researched and developed by Dow Chemical the earliest emerged rapidly, and particularly in the low-temperature floor radiant heating field, its consumption is doubled and redoubled.This material is compared with traditional polyolefine material has high temperature resistant, anti-low temperature brittleness, compressive strength advantages of higher.But this material can't satisfy the required mechanical strength of building because of its rigidity difference, can't use at high temperature more than 70 ℃ for a long time, has limited its application in fields such as Building Heat water pipes.The extensively popularization and application of domestic PP-R pipeline, because the PP-R pipe exists low temperature brittleness big, the shortcoming that linear expansion coeffcient is high, the tubing fracture phenomena can appear in construction in the winter time.
(3) summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned material, bring into play its advantage, it is good to design a kind of anti-low temperature brittleness, compressive strength height, mechanical strength, and heat resistance improves fiber/non-crosslinked heat-proof polythene composite pipe that linear expansion coeffcient significantly descends.
The utility model is achieved in that a kind of fiber/non-crosslinked heat-proof polythene three-layer composite pipe, comprise the outer and tube wall internal layer of tube wall of non-crosslinked heat-proof polythene, it is characterized in that in the middle of non-crosslinked heat-proof polythene tube wall skin and tube wall internal layer, having one to comprise glass fibre and wollastonite fiber and non-crosslinked heat-proof polythene composite material mesosphere.
Advantage of the present utility model: owing to have one to comprise glass fibre and wollastonite fibre and non-crosslinked heat-proof polythene composite material mesosphere with skin is middle at the tube wall internal layer of non-crosslinked heat-proof polythene, improved intensity and resistance to heat, expansion coefficient can drop to the non-crosslinked heat-resisting polyethylene tube expansion coefficient 1/3.Resistance to low temperature of the present utility model is compared the raising that matter is arranged with the PP-R pipe, even under-20 ℃ low temperature, tubing can not destroy because of fragility yet.Be applicable to building field hot and cold water pipeline system and other industrial piping systems.
(4) description of drawings
Accompanying drawing is the utility model embodiment, and Fig. 1 is the generalized section of fiber/non-crosslinked heat-proof polythene three-layer composite pipe.Symbolic representation is as follows among the figure: tube wall skin 1, tube wall internal layer 2, by glass fibre and wollastonite fibre and non-crosslinked heat-proof polythene composite material tube wall mesosphere 3, glass fibre 4, wollastonite fibre 5, non-crosslinked heat-proof polythene 6.
(5) embodiment
Thickness by glass fibre 4 and wollastonite fibre 5 and non-crosslinked heat-proof polythene 6 composite material tube wall mesospheres 3 is the 33%-40% of pipe thickness.
Claims (2)
1. fiber/non-crosslinked heat-proof polythene three-layer composite pipe, the tube wall skin (1) and the tube wall internal layer (2) that comprise the non-crosslinked heat-proof polythene is characterized in that there is one by glass fibre (4) and wollastonite fibre (5) and non-crosslinked heat-proof polythene (6) composite material tube wall mesosphere (3) in the tube wall skin (1) and tube wall internal layer (2) centre of non-crosslinked heat-proof polythene.
2. according to the described a kind of fiber of claim 1/non-crosslinked heat-proof polythene three-layer composite pipe, it is characterized in that the thickness by glass fibre (4) and wollastonite fibre (5) and non-crosslinked heat-proof polythene (6) composite material tube wall mesosphere (3) is the 33%-40% of pipe thickness.
