Problems solved by technology

[0004] However, after the drip irrigation pipe has been used for a long time, the rodents have adapted to the smell of capsaicin or the content of capsaicin has decreased due to the forward movement to the outside world, which will lead to weakened rodent-proof effect and reduced avoidance effect

Embodiment 1

[0023] Example 1 Preparation of ethyl cellulose microencapsulated capsaicin granules

[0024] (1) 8g ethyl cellulose (wall material) is added in 60ml methylene dichloride, form ethyl cellulose solution;

[0025] (2) Add 0.4g capsaicin nanopowder to the ethyl cellulose solution, then add 2.5% vol of OP-10 emulsifier, ultrasonic 30min, to form an emulsion;

[0026] (3) Drop the above emulsion into 500ml of deionized water at a rate of 3ml / min and stir and heat. After the dropwise addition, continue to stir and slowly heat to 60°C. Microcapsule particles are obtained after 1h, and the resulting product is filtered. Wash with deionized water and dry to obtain capsaicin microencapsulated particles.

Embodiment 2

[0027] Example 2 Preparation of rodent-proof masterbatch

[0028] After the mass fraction is 10% rodent-proof agent A, 10% cinnamic amide, 60% low-density polyethylene, 1% antioxidant 1010, and 19% ethylene vinyl acetate are mixed uniformly, heated and plasticized, Extrude, shape, cool, pelletize, and air-dry to make rodent-proof masterbatch.

Embodiment 3

[0029] Example 3 Preparation of rodent-proof masterbatch

[0030] The preparation method is the same as in Example 2, and the raw material composition is different from that of Example 2, being 20% ​​rodent-proof agent A, 10% cinnamic amide, 50% low-density polyethylene, 1% antioxidant 1010, and 19% ethylene acetic acid vinyl ester.

Abstract

The invention provides a rat-proof buried drip irrigation pipe. The drip irrigation pipe is made of the following components in parts by mass: 40-60 percent of high density polyethylene, 10-30 percent of low density polyethylene, 10-30 percent of linear low density polyethylene, 1-10 percent of rat-proof master batch and 1-2 percent of multifunctional master batch, wherein the rat-proof master batch is prepared from raw materials comprising ethyl cellulose microencapsulated capsaicine particles and cinnamamide. The invention further provides a manufacturing method of the drip irrigation pipe. Through adoption of a co-extrusion technology, rat-proof components exist in the drip irrigation pipe in the form of a color bar. The drip irrigation pipe has a good rat-proof effect, and acts for a longer time.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation equipment, in particular to a drip irrigation pipe, more specifically to a rodent-proof buried drip irrigation pipe and a preparation method thereof. Background technique [0002] Drip irrigation is one of the most efficient fertilization and irrigation technologies for farmland irrigation so far. It can achieve small water and frequent irrigation, so that water can slowly and evenly infiltrate the soil, maintain the soil structure, and form a suitable soil water, fertilizer, and heat environment. . The buried drip irrigation technology has obvious water-saving effect and has many advantages as follows: 1. The emitter is buried below the surface and will not generate surface runoff, which minimizes the water content of the surface soil and reduces the evaporation loss between trees; 2. Capillary pipes and emitters can be buried in the ground for many years, avoiding the trouble of...
