Composite material inlaid cylindrical dripper thin-wall drip seepage zone and its manufacturing method

Abstract

The invention provides a thin-wall infiltration belt inlaid with a cylindrical dripper in a cladding material and a preparation method thereof, which is composed of a molding belt and a cylindrical dripper. Layer is EVA modified polyethylene material, B layer is polypropylene material, A+B structure from inside to outside, or A+B+A structure, wall thickness is 0.1 ~ 0.3mm; the cylindrical dripper is embedded in Inside the forming belt, the forming belt outside the water outlet position of the inlaid cylindrical dripper is provided with water outlet holes or slits. The cylindrical dripper is made of polyethylene (PE), preferably high-density polyethylene (HDPE). The cladding material provided by the present invention has a thinner wall thickness of the inlaid cylindrical dripper thin-wall drip seepage zone, which can save 40% of raw materials compared with the drip irrigation pipe, and significantly reduces product costs. The inner embedded cylindrical dripper is firmly bonded and does not fall off It is stretchable, resistant to internal pressure, and can be used repeatedly. It can be used to bury water seepage in shallow soil and irrigate plants with water, fertilizer and medicine.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation and water delivery, and in particular relates to a thin-wall drip seepage belt with a cylindrical drip head embedded in a cladding material and a manufacturing method. Background technique [0002] The drip seepage belt for agricultural planting is based on the water requirements of the crops, transporting water, fertilizers, pesticides, etc. together and slowly dripping into the soil at the roots of the crops, avoiding the leakage, volatilization and waste of water, fertilizers and pesticides during the transportation process. It can save water and fertilizer to the greatest extent and reduce costs, which is of great significance in water-scarce areas. With the development of modern agricultural technology, the use of drip seepage zone is increasing. [0003] The wall thickness of the drip irrigation belt is relatively thin, and it is wound into a strip shape. The common ones are ...

AI Technical Summary

Problems solved by technology

[0003] The wall thickness of the drip irrigation belt is relatively thin, and it is wound into a strip shape. The common ones are patch or labyrinth drip irrigation belts. Narrow and short, easy to block; labyrinth drip irrigation tape has many bonding points, is easy to age and crack, and is not resistant to internal pressure. These two products are not conducive to repeated use, and the service time is short; the inner cylindrical drip irrigation tube is not easy to block because it drips water through the cylindrical dripper , used for a long time, but its outer wall is made of polyethylene material. Due to the low mechanical properties of polyethylene material, the wall thickness is generally above 0.5mm. If it is too thin, it will cause poor tensile and internal pressure resistance. The original equipment, The material and process cannot produce the thin-walled cylindrical drip zone
