Abstract
The present invention relates to one kind of multilayer environment protecting composite plastic pipe and is especially multilayer environment protecting composite plastic pipe of two or more layers of different material. The multilayer plastic pipe has an inner layer of pressure-resisting plastics and one or more outer layers of plastics with relatively high cost and mild pressure-resisting performance. Compared with other plastic pipe in the same thickness, the present invention has high comprehensive performance, simpdle production process and low cost.
Description
[technical field]
The present invention relates to a kind of multilayer environment protecting plastic composite pipe, more particularly it is the multilayer environment protecting plastic composite pipe that two layers or more different materials is composited.
[background technology]
At present, PVC (polyvinyl chloride) tube and tube spare can only connect or tooth connect with glue, and do not resemble PP-R (polypropylene) and PE (polyolefin) pipe can the installation of usefulness hot melt connection; As connecting with glue, the junction time is long aging easily, cause seepage easily, and glue also has pollution; And the fracture easily of the tooth connection tooth place of connecing, relative cost is also higher.These two kinds of methods of attachment all have influence on promoting the use of of plastic pipe on a large scale.
[summary of the invention]
The objective of the invention is to overcome above-mentioned weak point of the prior art, a kind of compliance with environmental protection requirements is provided, be easy to widely used novel tube.
Purpose of the present invention can reach by following measure:
Multilayer environment protecting plastic composite pipe, its internal layer be by withstand voltage properties organic plastics (1) preferably, and its skin is general but organic plastics (2) composition that can install by the hot melt connection when reality is used of compound one deck withstand voltage properties.
Multilayer environment protecting plastic composite pipe, the internal layer that it is characterized in that it is a withstand voltage properties organic plastics (1) preferably, the organic plastics (2) that compound one deck withstand voltage properties is general on inner layer outer wall also has one or more layers of organic plastics (3) on the outer wall of described organic plastics (2).
Described organic plastics (1) is better, lower-cost PVC material of withstand voltage properties or the close material of other character.
Described organic plastics (2) is that cost is higher and PP-R or PE material or the close material of other character that withstand voltage properties is general.
Described organic plastics (1), organic plastics have one deck adhesive layer between (2).
Described organic plastics (1), organic plastics (2), organic plastics have one deck adhesive layer between (3).
The present invention has following advantage compared to existing technology:
1. draw materials easily, PVC, PP-R, PE all be conventional material, easy to use safe and reliable, be difficult for aging, fracture, seepage phenomenon, weather resisteant can be excellent.
2. making is simple, integrated cost is cheap, the market competitiveness is strong
[description of drawings]
Fig. 1 is that environment protecting plastic composite pipe of the present invention cuts open for two layers and shows structural representation.
Fig. 2 is that environment protecting plastic composite pipe of the present invention cuts open for three layers and shows structural representation.
[specific embodiment]
The present invention is further detailed in conjunction with the accompanying drawings below:
Fig. 1 is one embodiment of the present of invention.
Fig. 2 is an alternative embodiment of the invention.
As can be seen from Figure 1: organic plastics (1) is that withstand voltage properties is better, the material PVC that cost is low or other character identical materials, and organic plastics (2) material that withstand voltage properties is general by cost is higher is as PP-R or PE or other character identical materials.
As can be seen from Figure 2: internal layer is a withstand voltage properties organic plastics (1) preferably, and the organic plastics (2) that compound one deck withstand voltage properties is general on inner layer outer wall also has one deck organic plastics (3) on the outer wall of described organic plastics (2).
Need to prove that to those of ordinary skill in the art can also make some improvement and distortion to the present invention, this belongs to protection scope of the present invention equally.
Claims (6)
1. multilayer environment protecting plastic composite pipe, the internal layer that it is characterized in that it is a withstand voltage properties organic plastics (1) preferably, its skin is that withstand voltage properties is general but can form by the organic plastics (2) that the hot melt connection is installed when reality is used.
2. multilayer environment protecting plastic composite pipe, the internal layer that it is characterized in that it is a withstand voltage properties organic plastics (1) preferably, the organic plastics (2) that compound one deck withstand voltage properties is general on inner layer outer wall is also having one deck or the above organic plastics (3) that can install by the hot melt connection when reality is used on the outer wall of described organic plastics (2).
3. multilayer environment protecting plastic composite pipe according to claim 1 and 2 is characterized in that described organic plastics (1) is the better PVC material of withstand voltage properties.
4. multilayer environment protecting plastic composite pipe according to claim 1 and 2 is characterized in that described organic plastics (2) is PP-R or PE material.
5. multilayer environment protecting plastic composite pipe according to claim 1 is characterized in that described organic plastics (1), organic plastics have one deck adhesive layer between (2).
6. multilayer environment protecting plastic composite pipe according to claim 1 and 2 is characterized in that described organic plastics (1), organic plastics (2), organic plastics have one deck adhesive layer between (3).
