Problems solved by technology

The disadvantage of this invention is that a large amount of water glass and organic polymer materials are used in the raw materials, and such sand-fixing agents will still cause secondary harm to the environment
Chinese patent (CN 103289017 A) uses clay as the main raw material to graft and copolymerize acrylamide and bio-glue to obtain sand-fixing agent. Although the invention mentions the effect of water retention and heat preservation, the use of polyacrylamide in large quantities increases the cost of materials and reduces The degradation ability of the material

Abstract

The invention discloses a multifunctional clay-base sand stabilizing material integrating a water saving function, a temperature regulation function and a sand stabilizing function, and belongs to the field of sand control and sand stabilization. The sand stabilizing material adopts clay, biomass waste, animal bones, animal excrement, perlite, lactic acid, potassium hydroxide, phosphoric acid, natural emulsifier and cellulose as raw materials and is prepared in a given process. When in use, the clay-base sand stabilizing material is directly sprayed onto the surface of desert by utilizing a spraying device, and the crust thickness is controlled at 5mm to 10mm. The experiment shows that the product integrates the temperature regulation function, the water saving function and the sand stabilizing function; moreover, raw materials are natural products, so that the cost is low, the preparation process is simple, secondary environmental pollution is avoided, and the clay-base sand stabilizing material plays a positive role in restoring and rebuilding vegetation of a desert area.

Description

technical field [0001] The invention relates to a clay-based sand-fixing material, in particular to a clay-based sand-fixing material with water-saving, temperature-regulating and sand-fixing functions, belonging to the field of sand control and sand fixing. Background technique [0002] Land desertification is a worldwide ecological environment problem. According to the statistics of the United Nations Environment Program (UNEP), the areas that have been and are expected to be affected by desertification account for 35% of the global land area. my country is one of the countries with severe desertification in the world. The results of the national survey of deserts, Gobi and sandy land and desertification investigations show that the desertification land area in my country is 2.622 million square kilometers, accounting for 27.4% of the country's land area. Nearly 400 million people are affected by desertification. 120 billion yuan, ecology, society and economy have been se...
