Abstract

The invention discloses a novel environment-friendly water-retention anti-evaporation composite material. The novel environment-friendly water-retention anti-evaporation composite material comprises the following raw materials in parts by weight: 20-40 parts of a montmorillonite / agarose composite material, 10-30 parts of modified activated carbon and 40-60 parts of humic acid. The environment-friendly water-retention anti-evaporation composite material is prepared by the method comprising the following steps: (1) carrying out organic modification treatment on montmorillonite; (2) carrying out intercalation compounding on agarose and modified montmorillonite to form a montmorillonite / agarose composite material; (3) modifying activated carbon; and (4) uniformly mixing the prepared montmorillonite / agarose composite material, modified activated carbon and humic acid to obtain the environment-friendly water-retention anti-evaporation composite material. After the composite material is in contact with water, a water-retention film is formed, the water-retention film has the effects of blocking moisture in soil from permeating and enabling roots of plants to pass through the film, has good water-retention and water-blocking effects and can be used as a water-retention and waterproof agent and the water-retention and water-blocking time of the water-retention film is not less than 280 days.

Description

technical field [0001] The invention relates to a novel environmentally friendly water-retaining and anti-evaporation composite material with water-retaining and water-repelling functions, a preparation method thereof, and an application as a water-retaining and water-repelling agent in desertification control. Background technique [0002] The world's land area is 162 million square kilometers, of which the desert area accounts for 20% of the total land area, and 43% of the land is facing the threat of desertification. In my country, the desertification area accounts for 17% of the total land area of ​​the country. Desertification seriously destroys land resources, reduces the land area available for farming and animal husbandry, degrades the land's reproductive capacity, reduces the number of plants, reduces the livestock capacity of the land, and reduces the yield per unit area of ​​crops. Desertification has caused serious losses to agriculture, animal husbandry and peo...
