Problems solved by technology

At present, the traditional inlaid patch type drip irrigation belt is common in the market, that is, the dripper is only installed on one side. Such a drip irrigation belt has disadvantages such as not suitable for densely planted crops, and the dripper is easy to block.
Due to its limited range of use and conditions of use, traditional inlaid patch drip irrigation belts cannot be used in densely planted crops and crops that require large amounts of water.

Abstract

The invention discloses a double-dropper inlaid patch drip irrigation belt and a preparation method thereof. The double-dropper inlaid patch drip irrigation belt comprises a drip irrigation belt body, wherein droppers are arranged on two sides of the drip irrigation belt body, wherein the droppers on the two sides are arranged in parallel in a staggered manner; and the distance between the droppers on the same side is 300-600mm. The preparation method comprises the following steps: mixing 44-48 parts of high density polyethylene, 23-27 parts of low density polyethylene, 25-26 parts of linear low density polyethylene, 2-3 parts of carbon black, and 0.3-0.8 part of PPA multifunctional master batch, extruding by using an extruder, thermally adhering to an inner wall of the drip irrigation belt, sizing, cooling, setting, pulling, and punching, thereby obtaining the final product. According to the invention, the droppers are arranged on two opposite sides of the drip irrigation belt, and the droppers are arranged in parallel in the staggered manner, so that the drip irrigation belt has a good irrigation effect on an area in which intensive crops are planted, and is wide in application range. Moreover, the drip irrigation belt has high anti-blockage capability in long-term using process.

Description

technical field [0001] The invention belongs to the technical field of drip irrigation belts for agricultural irrigation, and in particular relates to a double-drip drip irrigation belt inlaid with patches and a preparation method thereof. Background technique [0002] The drip irrigation tape is made of polyethylene as the main raw material, and is prepared by adding various auxiliary materials such as carbon black and PPA multifunctional masterbatch. It has the advantages of good tensile strength, flame retardancy, corrosion resistance, and electrical insulation properties. At present, the traditional inlaid patch type drip irrigation belt is common in the market, that is, the dripper is only installed on one side. Such a drip irrigation belt has the disadvantages that it is not suitable for densely planted crops and the dripper is easy to block. Due to its relatively limited range of use and conditions of use, traditional inlaid patch drip irrigation belts cannot be used ...
