Problems solved by technology

However, the use of this type of chemical curing agent is similar to covering the sand surface with a thin skin filled with sand. During use, the thin skin will often be damaged or even completely peeled off due to construction or wind erosion. problems, resulting in little effect in desertification control

Abstract

The invention provides a chemical curing agent as well as a preparation method and application thereof and belongs to the field of curing agents. The chemical curing agent is prepared from a first component and a second component, wherein the first component is mainly prepared from water, polyvinyl alcohol, polyacrylamide and acrylate; the second component is a solution containing sodium silicate with the percentage concentration of 2 to 5 percent. The preparation method of the curing agent comprises the following steps: mixing the polyvinyl alcohol, the polyacrylamide and the acrylate with water, and carrying out heating reaction at the temperature of 60 to 80 DEG C for 30 to 120 minutes to obtain the first component; preparing the sodium silicate solution with the mass concentration of 2 to 5 percent, thus obtaining the second component. The chemical curing agent has bionic performance, i.e., the chemical curing agent can form chemical crust on the sand surface; the chemical crust is similar to biological crust, and can be used for long-acting immobilized governance on sand grains, so that the weather-proof capability and the water erosion resistance of desert are improved.

Description

technical field [0001] The invention relates to the field of curing agents, in particular to a chemical curing agent and its preparation method and application. Background technique [0002] Sandy desertification (desertification for short) is a process of land degradation caused by the combination of irrational human activities and changes in natural conditions. During this process, land productivity is greatly reduced, and even becomes unusable land, causing sandstorms, sandstorms and other disasters, seriously endangering industrial and agricultural production, and reducing people's quality of life. [0003] Desertification is one of the main types of desertification. As an extremely important environmental and socio-economic problem, it plagues the world today and threatens the survival and development of human beings. The global desertification area has reached 36 million square kilometers, accounting for 1 / 4 of the world's land area, and it is expanding at a rate of 5...
