Water-saving composite infiltrating irrigation pipe and preparation method thereof

[0052] The present invention also provides a preparation method of the above-mentioned water-saving composite infiltration irrigation pipe, comprising the following steps:

[0053] S1, prepare the permeation film layer.

[0054] S2, prepare the base layer of infiltration irrigation.

[0055] S3. In order to prevent the infiltration irrigation substrate layer from causing damage to the infiltration irrigation film layer, a protective inner layer is provided on the outside of the infiltration irrigation substrate layer prepared in step S2, and then the infiltration irrigation film layer prepared in step S1 is wrapped in the protection. outside of the layer.

[0056] Preferably, in order to prevent clogging inside the percolation base layer, a protective layer such as a sponge may also be provided inside the percolation base layer.

[0057] The above step S1 includes:

[0058] S11. Fiber pretreatment: In order to remove the oil on the surface of the fiber and improve its hydrophi

[0075] This embodiment provides a water-saving composite infiltration irrigation pipe, which includes an infiltration irrigation substrate layer and an infiltration irrigation film layer disposed outside the infiltration irrigation substrate layer.

[0076] A plurality of interconnected capillary pores are distributed in the substratum of infiltration irrigation, and the plurality of capillary pores extend from the inside of the substratum of submersion to the inner surface and the outer surface of the substratum, and communicate with the outside world. The infiltration membrane layer is formed by compounding the water-conducting fiber and the membrane layer matrix. Both ends of the water-conducting fibers are exposed on the two sides of the film substrate. The water-conducting fibers include filaments and polyacrylamide-montmorillonite composite water-conducting materials coated on the surfaces of the filaments.

[0077] Wherein, the preparation method of the permeation film la

[0089] This embodiment provides a water-saving composite infiltration irrigation pipe. The difference from Embodiment 1 is that in the process of preparing the polyacrylamide-montmorillonite composite water-conducting material, the mass ratio of polyacrylamide and montmorillonite is 0.1.
