Sand fixing agent capable of preventing exposed soil from dust-raising and preventing sand from drifting, and preparation method and application thereof

Abstract

Embodiments of the invention provide a sand fixing agent capable of preventing exposed soil from dust-raising and preventing sand from drifting, and a preparation method and an application thereof. The sand fixing agent comprises the following components in parts by mass: 0.01 to 15 parts of macromolecular polymers, 0.01 to 15 parts of alkalis, 0.01 to 15 parts of esters and a proper amount of water. The preparation method comprises the following steps: uniformly mixing the macromolecular polymers, the esters, the alkalis and the water under stirring so as to form the sand fixing agent. The sand fixing agent provided by the embodiments of the invention can be applied to the aspects of preventing exposed soil from dust-raising and preventing sand from drifting, and is specifically applicable to desert control. Through preparation into an aqueous solution by combining the macromolecular polymers, the esters and the alkalis in a certain proportion, and application to the surface of soil,the sand fixing agent bonds soil particles into a large aggregate structure, and can realize a relatively-stable surface layer insusceptible to wind erosion and water erosion when the content reachesa certain number, thereby reaching the effect of fixing sand and obtaining a pioneering significance.

Description

Technical field [0001] The invention relates to the field of sand prevention and sand control, and in particular to a sand fixation agent for preventing dust from exposed soil and preventing quicksand, and a preparation method and application thereof. Background technique [0002] The world today is facing serious ecological problems such as serious destruction of forest vegetation and serious soil sandification and desertification, which pose a serious threat to the sustainable development of society. The total desert area in my country is 1.308 million square kilometers, accounting for 13.6% of the total land area in the country. Desertification not only worsens the originally fragile ecological environment, but also affects industrial and agricultural production and people's lives in desertified areas, severely restricting social and economic development, and becoming a major national ecological environmental problem. From a global perspective, the United Nations officially l...

Problems solved by technology

However, the technical effect of chemical control is not obvious enough, and the ideal sand fixation effect cannot be achieved only by using simple chemical binders.
