Abstract
The utility model discloses a multilayer co-extrusion ultrathin pressure-resistance plastic drip irrigation tape, which belongs to the technical field of agricultural irrigation and solves the problem that a pressure-resistance standard of 0.1MPa cannot be met when the wall thickness of a plastic drip irrigation tape is smaller than 0.20mm. The multilayer co-extrusion ultrathin pressure-resistance plastic drip irrigation tape comprises a main water delivery pipeline and a maze runner, a thermocompression sealed edge is arranged on one side of the drip irrigation tape and is provided with the discontinuous or continuous maze runner, the maze runner is provided with water inlets communicated with the main water delivery pipeline and water outlets communicated with the outside, the rest part of the drip irrigation tape is the main water delivery pipeline, the pipe wall of the main water delivery pipeline consists of an inner layer, a main structural layer and an outer layer, a special functional layer is respectively arranged between the inner layer and the main structural layer as well as between the main structural layer and the outer layer, one special functional layer has an axial molecular orientation, the other special functional layer has a radial molecular orientation, the inner layer is made of low-density polyethylene, and the special functional layers, the main structural layer and the outer layer are made of linear low-density polyethylene. According to the utility model, the production cost on the wall thickness of the drip irrigation tape can be greatly reduced, the uniformity of the drip irrigation tape can be greatly improved, and plastic materials can be saved by 40%.
Description
One, technical field the utility model belongs to agricultural irrigation technology, particularly relates to a kind of perforated pipe-line that uses and is installed in watering apparatus on the ground.
Two, the background technology irrigate band can be around the crooked laying of ridge, and easy to operate, labyrinth flow-path designs, water outlet is even, can reach more than 85%, laying can reach 80m, many mouthfuls of water outlets of turbulent, anti-blockage capability is strong, labyrinth flow-path reaches a hole vacuum integral heat pressure moulding, cohesive is good, and accuracy of manufacture height is in light weight, installation administration is convenient, and artificial mounting cost is low.But existing irrigate band mostly is single layer structure, carries out " GBT19812 plastics water-saving irrigation equipment " standard, i.e. the single layer structure water-saving irrigation that is made of a kind of plastic material just can reach withstand voltage standard 0.1MPa with plastics irrigate band wall thickness 〉=0.20 millimeter.
Three, the summary of the invention the purpose of this utility model provides a kind of multi-layer co-extruded ultra-thin pressure-resistant plastic irrigate band, do not reach the problem of withstand voltage standard 0.1MPa when having solved plastics irrigate band wall thickness less than 0.20 millimeter, it comprises water delivery trunk line and labyrinth flow-path, one side is a hot-pressing, edge-sealing in the irrigate band, hot-pressing, edge-sealing is provided with and is interrupted or continuous labyrinth flow-path, labyrinth flow-path is provided with water inlet that is communicated with the water delivery trunk line and the delivery port that communicates with the external world, remainder is the water delivery trunk line, water delivery trunk line tube wall is by internal layer, main structure layer and outer the composition, between internal layer and main structure layer and between main structure layer and skin, be provided with the specific function layer, the molecularly oriented of specific function layer, wherein one deck is axial, another layer is for radially, internal layer is a low density polyethylene (LDPE), the specific function layer, main structure layer and skin are LLDPE, can reduce the wall thickness of irrigate band significantly and extrude production cost, improve the uniformity of irrigate band significantly, water delivery trunk line thickness of pipe wall≤0.12 millimeter, can reach the requirement of withstand voltage 0.1MPa, save 40% plastic material.
