Abstract
The utility model discloses a three-layer coextrusion drop irrigation pipe which adopts the manufacturing technique of the coextrusion molding by three extruders. A water outlet is drilled on the adhesive position of a water outlet window of a water dropper and a pipe wall. The utility model is characterized in that the pipe wall of a drop irrigation pipe is synthesized by a water resistant layer, a foaming layer and an aging resistant layer. The utility model has the advantages of light weight, sound isolation, heat preservation, insulation, flame resistance, low cost, etc. Besides, the service life of the drop irrigation pipe can not be shortened. The utility model is a novel product for a drop irrigation pipe, has strong competitive power and wide market, and is favorable to the popularization and the application for the drop irrigation pipe.
Description
Technical field
The utility model relates to a kind of drip irrigation pipe, relates in particular to a kind of three-layer co-extruded drip irrigation pipe.
Background technology
China's its structure of existing drip irrigation pipe is that polyethylene is made tubing, in tubing, be bonded with water-dropper every certain distance, water outlet window at water-dropper has delivery port with the position that tube wall glues mutually, the production of its tube wall is adopted separate unit extruder and individual layer head and is that pure polyethylene raw material is made, and manufacturing cost is higher; Because the water resources shortage of China, add country in recent years to the applying of drip irrigation technique, large tracts of land is accepted by agriculture and forestry and green area irrigation, and the expensive of drip irrigation pipe formed restriction to further applying.Reduce the manufacturing cost of drip irrigation pipe, alleviate the production cost of agricultural, become the task of top priority of each manufacturing enterprise.
Summary of the invention
The purpose of this utility model is, a kind of three-layer co-extruded drip irrigation pipe is provided, this drip irrigation pipe adopts the production technology manufacturing of three extruder coextrusion molds, the tubing of this drip irrigation pipe is divided into three layers, and its ectonexine is respectively new polyethylene raw material, and sandwich layer is a polyethylene foam-material, this drip irrigation pipe has light weight, sound insulation, insulation, insulation, fire-retardant, low cost and other advantages, be the novel product of drip irrigation pipe, have very strong competitiveness, have vast market.
The technical solution that realizes above-mentioned purpose is, this three-layer co-extruded drip irrigation pipe is stained with water-dropper on the drip irrigation pipe inwall, is equipped with delivery port on the bonding position of the water outlet window of water-dropper and tube wall; It is characterized in that the tube wall of drip irrigation pipe is synthetic by water barrier, foaming layer and anti-aging layer.
Some other characteristics of the present utility model are, described water barrier (3), foaming layer (2) and anti-aging layer (1) be respectively drip irrigation pipe the tube wall gross thickness 10%, 80% and 10%.
The material of described foaming layer is a polyethylene.
The material of described anti-aging layer adds carbon black for the polyethylene raw material and age resister constitutes.
Three-layer co-extruded drip irrigation pipe of the present utility model adopts the manufacturing process of above-mentioned drip irrigation pipe, and it does not change existing drip irrigation pipe structure, alleviated the weight of drip irrigation pipe, reduce manufacturing cost, and do not influenced the service life of drip irrigation pipe, be beneficial to applying of drip irrigation pipe.
Description of drawings
Fig. 1 is a schematic cross-section of the present utility model; What the symbol among the figure was represented respectively is: 1, anti-aging layer, 2, foaming layer, 3, water barrier.
The present invention is described in further detail below in conjunction with embodiment that accompanying drawing and inventor provide.
Embodiment
Referring to Fig. 1, three layers of drip irrigation pipe of the present utility model are irritated on the inside pipe wall and are stained with water-dropper, are equipped with delivery port on the bonding position of the water outlet window of water-dropper and tube wall; The tube wall of drip irrigation pipe is synthetic by water barrier 3, foaming layer 2 and anti-aging layer 1.
From the cross section, the tube wall of this layer drip irrigation pipe is formed by three layers altogether.Be respectively anti-aging layer 1 from outside to inside, anti-aging layer 1 is to constitute with the carbon black of polyethylene interpolation 5%～10% and 1%～5% age resister, and its thickness is 10 of tube wall gross thickness, and its effect is that wind resistance blows Exposure to Sunlight, keep appearance tactile impression, increase the service life; Through evidence, the carbon black and the age resister that add aforementioned proportion in polyethylene are suitable; Next is foaming layer, and the material of this layer adopts polyethylene, also can use waste and old plastics, and its thickness is 80 percent of tube wall gross thickness, and it has alleviated weight greatly and has reduced cost; Innermost layer is a water barrier, adopts polyethylene to make, and its thickness is 10 of tube wall gross thickness, and this water barrier can prevent effectively that irrigation water from entering foaming layer and water-dropper cementation, do not influence the bonding fixing of water-dropper and tube wall.
The use of this drip irrigation pipe is identical with other drip irrigation pipe, and irrigation water enters in the pipe, splashes into the field by water-dropper outside tube wall.
Claims (5)
1. a three-layer co-extruded drip irrigation pipe is stained with water-dropper on the drip irrigation pipe inwall, is equipped with delivery port on the bonding position of the water outlet window of water-dropper and tube wall; It is characterized in that the tube wall of drip irrigation pipe is synthetic by water barrier (3), foaming layer (2) and anti-aging layer (1).
2. three-layer co-extruded drip irrigation pipe as claimed in claim 1 is characterized in that, described water barrier (3), foaming layer (2) and anti-aging layer (1) be respectively drip irrigation pipe the tube wall gross thickness 10%, 80% and 10%.
3. three-layer co-extruded drip irrigation pipe as claimed in claim 1 is characterized in that, the material of described foaming layer (2) is a polyethylene.
4. three-layer co-extruded drip irrigation pipe as claimed in claim 1 is characterized in that, the material of described anti-aging layer (1) adds carbon black for the polyethylene raw material and age resister constitutes.
