Clay-based thermal phase transition multifunctional sand fixing material and preparation method thereof

Abstract

The invention discloses a clay-based thermal phase transition multifunctional sand fixing material, and belongs to the technical field of sand preventing and sand fixing. The material is prepared by a method which comprises the following steps: crushing biomass waste into crushed slag; mixing a biomass degradable raw material and the biomass waste slag in a certain proportion at a high speed; then, performing vacuum immersion treatment to obtain a thermal phase transition energy storage additive; finally, uniformly mixing the thermal phase transition energy storage additive and clay in a certain proportion, paving and spreading the mixture on the surface of a moving dune, and spraying water on the mixture to enable the water to penetrate into the surface and crusts. A heat energy storage phase transition material and a water retaining material which are relatively low in cost are introduced by adding a chemical sand fixing idea on the basis of a clay-based sand fixing material; the prepared energy storage thermal phase transition multifunctional clay-based sand fixing material has the advantages of physical sand fixing, chemical sand fixing and plant sand fixing; the sand fixing effect is good; the cost is low; meanwhile, the problems in pure physical sand fixing and chemical sand fixing are solved, and the difficult points of the plant sand fixing is also solved, so that the clay sand fixing can be popularized and applied more comprehensively.

Description

technical field [0001] The invention relates to a clay-based sand-fixing material, in particular to the preparation of a clay-based thermal phase change multifunctional sand-fixing material, which belongs to the technical field of sand prevention and sand fixation. Background technique [0002] In recent years, extreme weather has occurred frequently in western my country, among which sandstorms are the majority. The flowing sand dunes can easily cause wind and sand hazards. Sandstorms can bury crops, erode soil, and reduce soil fertility. Crops exposed to wind and sand for a long time will expose their root system and affect the growth and development of crops. Sandstorms can also delay crop development. For example, wind and sand delay the heading of wheat in winter by 3-7 days, and delay the initial flowering of soybeans by 7-14 days. The wind-sand damage of winter wheat 7-14 days after emergence (autumn) can reduce the dry weight of the harvest in the second year, an...

Problems solved by technology

In order to solve the problem of sand fixation by plants, many researchers have explored a large number of measures. Among them, the clay-based sand fixation material (201110122445.3) invented by Northwest Normal University can solve the problem of quicksand movement from the root, and can also provide certain nutrients for the survival of plants. , but the regulation of surface temperature and moisture is still insufficient
