Embodiment 1

[0036] The novel drip irrigation belt in the present application is made from the raw materials of the dosage shown in Table 1, and is specifically prepared by the following method:

[0037] Preparation of shed film recycled material: choose high-pressure material type shed film waste, clean and pulverize the shed film waste;

[0038] The pulverized shed film waste is granulated under the conditions that the temperature of the first stage is 155 °C, the temperature of the second stage is 165 °C, the temperature of the third stage is 170 °C, the temperature of the fourth stage is 175 °C, and the temperature of the head is 180 °C. , for standby, to obtain the regenerated material of the shed film;

[0039] Preparation of drip irrigation belt recycled material: use low-pressure material type drip irrigation belt waste, wash and pulverize the drip irrigation belt waste;

[0040]The crushed drip irrigation tape waste is granulated under the conditions that the temperature of the f...

Embodiment 2-5

[0044] The new drip irrigation tapes of Examples 2-5 are exactly the same as the preparation methods and types of raw materials of Example 1, the difference is that the dosage of each raw material is different, as shown in Table 1 for details.

Abstract

The invention relates to the technical field of water-saving irrigation equipment, and particularly discloses a novel drip irrigation tape and a preparation method thereof. The novel drip irrigation tape is prepared from, by weight, 20%-25% of low-pressure materials, 16%-34% of greenhouse film regenerated materials, 40%-58% of drip irrigation tape regenerated materials, 0.5%-5% of color masterbatch and 0.5%-0.6% of PPA auxiliaries. The tensile strength of the novel drip irrigation tape is 27.7 MPa, the oxidation induction time of the novel drip irrigation tape is 61min, and the novel drip irrigation tape shows excellent toughness and strength. The lowest elongation at break is 636%. The novel drip irrigation tape is not damaged when passing through a drawing-resistant test, and has high drawing-resistant performance.

Description

technical field [0001] The present application relates to the field of water-saving irrigation equipment, and more particularly, to a novel drip irrigation belt and a preparation method thereof. Background technique [0002] Drip irrigation belt is a water-saving irrigation equipment that uses drip irrigation pipes to send water through orifices or drippers on capillary tubes with a diameter of about 10mm to the roots of crops for local irrigation. Drip irrigation can keep the soil near the roots of crops at a suitable humidity, and is the most effective water-saving irrigation method in arid and water-deficient areas. [0003] Drip irrigation tape is an important drip line in the drip irrigation system. However, most of the drip irrigation belts need to be exposed to the surface for a long time, and the phenomenon of pipe burst and fracture often occurs, which affects the normal irrigation. SUMMARY OF THE INVENTION [0004] In order to solve the problems of explosive pi...
