Composite water-permeable material, and production method and derivative products thereof

Abstract

The invention discloses a composite water-permeable material, and a production method and derivative products thereof. The composite water-permeable material is formed by mixing the components of: a chemical material base material, a plasticizer added into the chemical material, and a filling material added into the chemical material base material, wherein the filling material comprises nano-scale pores and is coated by using a separation agent. When the composite water-permeable material is processed, the separation agent is gradually subjected to a chemical reaction with benzene ring in the plasticizer, and is dissolved, such that the nano-scale micro-pores of the filling material are opened, and novel uniform and dense micro-pores are formed between the plasticizer and the filling material. The micro-pores communicate with each other, such that water-permeable channels are formed. The composite water-permeable material can be produced into water-permeable membranes, water-permeable pipes, and water-permeable containers. The products have uniform and dense nano-scale channels, and can be used in the field of agricultural water-saving irrigation. The products can be paved on the ground and / or can be buried under ground, and can be used for a long time. With the products, purposes of water saving, energy saving, labor saving, and eco-friendliness can be achieved.

Description

technical field [0001] The invention belongs to the field of agricultural water-saving irrigation, and specifically relates to a composite water-permeable material, a manufacturing method thereof and related products. Background technique [0002] Solving the problem of feeding more than one billion people is always the top priority in governing the country. my country is in the stage of rapid industrialization and urbanization, and the factors affecting national food security are complex. Although my country's grain production has achieved a rare "eight consecutive increases" in history, the production capacity is still unstable, resource constraints are becoming increasingly prominent, and the task of ensuring the balance between supply and demand of agricultural products such as grain is very arduous. [0003] The contradiction between increasing the number of people and reducing water shortage in our country is becoming more and more prominent, and the hard constraints ...

Problems solved by technology

In the 1920s, Germany used the water permeability of ceramics to fire seepage pipes and applied them to agricultural irrigation and achieved great success. In the following decades, Germany tried its best to promote this technology, but it was gradually abandoned due to the heavy and difficult construction of clay seepage pipes. From the 1980s to the 1990s, scientists developed and researched the use of rubber foaming technology to make rubber seepage irrigation pipes for agricultural irrigation, and built the largest manufacturer of rubber seepage irrigation pipes in China at that time in Shijiazhuang, Hebei, and began mass production; due to irrigation water quality and development The uncontrollability of the foam hole technology, in actual operation, the hole is seriously blocked, and even the plant root system is directly inserted into the foam hole, which seriously affects the use effect of the rubber seepage irrigation pipe and fails
