Preparation method of chemical crosslinking sand fixing material suitable for wind prevention and sand fixation of desert road

Abstract

The invention provides a preparation method of chemical crosslinking sand fixing material suitable for wind prevention and sand fixation of a desert road. The chemical sand fixing material is preparedfrom the following raw materials in parts by weight: 0.5-1 part of organic and inorganic composite super absorbent resin, 2-6 parts of a cellulose derivative, 5-10 parts of desert cement, 15-25 partsof black humic acid, 25-35 parts of inorganic nanoparticles, 10-20 parts of an organic fertilizer and 15-25 parts of a plant straw powder. The chemical sand fixing material has relatively strong sandfixing, crusting and crush-resisting and wind erosion-resisting performance, and can form a stable sand layer crust quickly on the surface of the sand to achieve a purpose of quick wind prevention and sand fixation.Moreover, the chemical sand fixing material also can play water retaining and warm keeping roles to provide nutritional conditions to wind prevention and sand fixation plants of the desert road. A sand fixer is primarily prepared from a natural raw material, is green and environment-friendly, is free of secondary pollution and is classified as a wind prevention and sand fixation material which is excellent in performance.

Description

technical field [0001] The invention relates to a preparation method of a chemically cross-linked sand-fixing material suitable for windbreak and sand-fixation of desert roads. Background technique [0002] With the continuous expansion of desertification in the world, it has had a huge impact on the life of human beings all over the world. my country is one of the countries with the largest population, the widest desert and the most serious damage from desertification in the world. The desertification of the land leads to the loss of water and plant nutrients, which seriously damages the biodiversity. With the aggravation of desertification, the number of plants has decreased, and the impact of wind and sand has increased, and the lives of our people have been seriously affected. [0003] The common control methods of desertification include engineering control, biological control and chemical control. Most of the engineering treatment is to set up sand barriers, grass gr...
