Preparation method of long-acting sand-fixing agent

Abstract

The invention discloses a preparation method of a long-acting sand-fixing agent, and belongs to the technical field of sand prevention and control. Modified bacterial cellulose and water are mixed according to a weight ratio of (1 to 8) to (1 to 10); sodium hydroxide solution of which mass is 0.1 to 0.2 time of that of the modified bacterial cellulose, crylic acid of which mass is 0.5 to 0.6 timeof that of the modified bacterial cellulose, an initiator of which mass is 0.1 to 0.2 time of that of the modified bacterial cellulose and N,N'-methylene bisacrylamide of which mass is 0.2 to 0.3 timeof that of the modified bacterial cellulose are added; a stirring reaction is performed in the nitrogen atmosphere; vacuum drying, grinding and sieving are carried out to obtain the long-acting sand-fixing agent. The long-acting sand-fixing agent prepared by the preparation method has excellent water retention performance.

Description

technical field [0001] The invention discloses a preparation method of a long-acting sand-fixing agent, which belongs to the technical field of sand control and sand prevention. Background technique [0002] Land desertification is one of the most serious ecological and environmental problems in the world. Most of the desertified land in China is wind-eroded desertified land and water-eroded desertified land. The current sand control methods mainly include biological sand control technology, engineering sand control technology and chemical sand fixation technology. [0003] The advantages of chemical sand fixation technology are low cost, quick effect and easy construction. Chemical sand fixation refers to the use of chemical materials and techniques to build a layer of consolidation layer on sand dunes or sandy surfaces that are prone to sand damage in wind-sand hazard areas, which can prevent wind blowing, maintain moisture and improve sand properties, so as to achieve T...
