Problems solved by technology

[0003] After the drip irrigation belt is burned, if the burned area is small and the situation is light, you can use electrical tape to wrap or cut it off and use a straight-through connection. If there are many burned areas and the burning area is large, you need to directly replace it with a new drip irrigation belt; drip irrigation belt The period of burns is usually during the crop growth and irrigation season. For farmers, once burns occur, the drip irrigation belt behind the burnt parts cannot achieve normal irrigation or uneven irrigation in the field, which seriously affects crop growth and causes economic losses. At the same time, if the field It is time-consuming and labor-intensive to deal with the burned drip irrigation belt, which in disguise causes losses to farmers

Abstract

The invention discloses an anti-burn double-layer co-extrusion built-in drip irrigation tape. The drip irrigation tape comprises an inner layer and an outer layer, wherein the inner layer is prepared from, by mass, 40-60% of high-density polyethylene, 10-30% of low-density polyethylene, 10-30% of linear low-density polyethylene, 1-2% of multifunctional master batch and 3-8% of silver master batch; the outer layer is prepared from, by mass, 60-80% of high-density polyethylene, 1-2% of AC foaming system, 1-2% of DCP cross-linking system, 15-30% of linear low-density polyethylene and 3-8% of silver master batch; concentration master batch is prepared from the AC foaming system and the DCP cross-linking system; the anti-burn capability of the drip irrigation tape is improved, and the service life of the drip irrigation tape is prolonged.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation equipment, and in particular relates to a drip irrigation pipe, and more specifically to a burn-resistant double-layer co-extruded inner-embedded drip irrigation belt and a preparation method thereof. Background technique [0002] Drip irrigation is currently the most water-saving irrigation method in arid and water-poor areas. It allows water to infiltrate the soil slowly and evenly, maintains the soil structure, and forms a suitable soil water, fertilizer, and heat environment; the utilization rate of drip irrigation Up to 95% can be combined with fertilization during drip irrigation at the same time, and the fertilizer efficiency can be doubled; the drip irrigation belt is the terminal sprinkler of the drip irrigation system, which is especially important for the irrigation system; the existing drip irrigation belt has the advantages of light weight, low installation cost, and co...
