Abstract

The invention provides a sand-fixing composition and a preparation method and an application thereof, and belongs to the field of desert treatment. Specifically, the sand-fixing composition comprisesthe raw material components in parts by weight: 50-80 parts of a first material, 10-30 parts of a second material, 0.5-2 parts of a microbial bacterial liquid, 10-20 parts of bentonite, 1-8 parts of sawdust, 5-10 parts of waste paper pulp and 200-300 parts of water. The sand-fixing composition provided by the invention has all the components well-matched; prepared liquid pre-used liquids have theviscosity of about 50-400 mPa*s, are quite easy to spray and are conducive to rapid sand fixation; two pre-used liquids are prepared by reaction of specific and complex components, and have excellentcohesiveness, fluidity and gas permeability, a formed bonding layer has high compressive strength which can reach 0.5 MPa or more, has excellent anti-aging performance and low loss rate in long-term use and has the loss rate after half a year of less than 30% .

Description

Technical field [0001] The invention relates to the field of desert treatment, in particular to a sand fixing composition and a preparation method and application thereof. Background technique [0002] Desertification is a major global environmental problem facing mankind at present, which is seriously afflicting the survival and development of human society. The wind erosion of the soil caused by the sand movement is one of the main manifestations of sandy desertification. The wind erosion, transportation and accumulation of the wind sand flow are the main causes of desertification. [0003] According to incomplete statistics, there are more than 1.5 million square kilometers of desert and desertified land in China, accounting for about 16% of the country’s land area. What’s more serious is that in recent decades, China’s desertified land has exceeded 1,000 square kilometers annually. The speed of land desertification continues to expand. There are as many as 10 provinces involve...
