Problems solved by technology

[0021] A micro-irrigation material with capillary permeation function and its preparation method, the material does not contain a release agent and a surfactant, and the proportion of inorganic fillers is relatively high, which overcomes the poor water seepage effect and large investment of materials in the prior art , high cost of raw materials, long process flow, low production efficiency, and high overall production cost. At the same time, the material has a capillary seepage network composed of hydrophilic inorganic filler particles evenly distributed in the non-hydrophilic thermoplastic matrix. This structure not only ensures the processing and use performance of the material, but also can automatically seep or stop the water seepage through the capillary network inside the material according to the water potential of the soil in contact with it.

[0113] The by-product salt mud (slurry) of the chlor-alkali industry is removed with a plate and frame filter press to remove excess water and dried, then ground and sieved to obtain a 10 micron (μ) salt mud powder filler, using a melt flow rate (MFR) of 4 Linear low-density polyethylene (LLDPE) resin is used as the base material, and the mass fraction ratio of filler to resin is 300:100; auxiliary agent is: hindered phenol antioxidant is tetrakis[β-(3.5-di-tert-butyl, 4- Hydroxyphenyl) propionic acid] pentaerythritol ester, the addition is 0.3 parts by mass, and the phosphite stabilizer is three (2.4-di-tert-butylphenyl) phosphite, and the addition is 0.3 parts by mass; the average molecular weight is 4000 high flow polyethylene (PE wax), the addition amount is 1 part by mass; 40% carbon black master batch containing 35 parts by mass of carbon black. The above components are added in three stages according to the metering. The first stage adds all the resins, additives and fi...

Embodiment 2

[0115] Calcium carbonate of 6.5 microns (μm) is used as a filler, and a low-density polyethylene (LDPE) resin with a melt flow rate (MFR) of 0.3 is a base material, and the mass and number ratio of the filler to the resin is 200: 100; the auxiliary agent is : The hindered phenolic antioxidant is tetrakis [beta-(3.5-di-tert-butyl, 4-hydroxyphenyl) propionate] pentaerythritol ester, the addition is 0.3 parts by mass, and the phosphite stabilizer is tri(2.4 -Di-tert-butylphenyl) ester, the addition amount is 0.3 parts by mass; the melt flow rate (MFR) is 30 high flow polyethylene (PE), the addition amount is 1 parts by mass. Add the above components into the twin-screw granulator in three stages according to the metering. The first stage adds all the resins, additives and fillers in corresponding proportions. The proportion of fillers added in each stage is 40% and 40% of the total amount of fillers. , 20%, using a twin-screw granulator with a screw diameter of 75 (φ75) and a len...

Embodiment 3

[0117] Use 1.6 microns (μm) of calcium carbonate as a filler, a high-density polyethylene (HDPE) resin with a melt flow rate (MFR) of 0.1 as a base material, and the mass and number ratio of filler to resin is 150: 100; the auxiliary agent is: The hindered phenolic antioxidant is tetrakis [β-(3.5-di-tert-butyl, 4-hydroxyphenyl) propionic acid] pentaerythritol ester, the addition amount is 0.3 parts by mass, and the phosphite stabilizer is tri(2.4- Di-tert-butylphenyl) ester, the addition amount is 0.3 parts by mass; the high flow polyethylene (PE) whose melt flow rate (MFR) is 70, the addition amount is 3 parts by mass. Add the above components into the twin-screw granulator in four stages according to the metering. The first stage adds all the resins, additives and fillers in corresponding proportions. The proportion of fillers added in each stage is 30% and 30% of the total amount of fillers. , 30%, and 10%, use a twin-screw granulator with a screw diameter of 75 (φ75) and a...

Abstract

The invention relates to a micro-irrigation permeating tube and a manufacturing method thereof. The micro-irrigation permeating tube comprises a capillary permeating tube (1) made of materials having a capillary permeating function is provided with hydrophilic inorganic fillers and a three-dimensional network capillary water seepage structure of thermoplastic plastics, and has unpowered, self-adaptive, continuous and balanced permeation functions, so that water can automatically permeates outward through a tubing or stops permeating outward according to water level of soil contacted with the capillary permeating tube. The capillary permeating tube further comprises a gel protective layer (4), high water retention tree powder is thrown into gaps of non-woven fabric and absorbs water to swell to form the gel protective layer. The tubing having good water permeating capacity can resist blockage, bacteria and prevent rats; by the adoption of the micro-irrigation permeating tube assisted by other irrigation components, an unpowered, self-adaptive, continuous and balanced permeating system which is applicable to the field of water-saving micro-irrigation is formed.

Description

technical field [0001] The invention relates to a water-saving micro-irrigation pipe, in particular to a buried micro-irrigation pipe with a seepage function. Background technique [0002] my country's water resources only account for 6% of the world's total, which is more scarce than cultivated land resources (accounting for 9% of the world's total). The shortage of water resources has become a bottleneck that seriously restricts the sustainable development of my country's national economy. Agriculture is the industry that consumes the most water in my country, accounting for more than 70% of the total water consumption, of which the water consumption for farmland irrigation accounts for 90% to 95% of the agricultural water consumption. However, the coexistence of shortage of water resources and waste of water resources in our country is very serious. Due to backward irrigation technology, serious waste of water resources and low utilization efficiency have exacerbated the...
