Embodiment 1

[0026] Example 1: 1 part of 32.5 silicon cement, 6 parts of desert sand, 0.05 part of cationic emulsified asphalt, 0.03 part of sodium polyacrylate super absorbent resin, 1 part of water, weighed in proportion and mixed evenly in a concrete mixer, sprayed On the surface of sand and dune that needs sand fixation, a polymer sand fixation layer with a thickness of 3-6mm is formed.

Embodiment 2

[0027] Example 2: 1 part of 42.5 normal silica cement or 52.5 normal silica cement, 8 parts of sand, 0.1 part of cationic emulsified asphalt, 0.1 part of sodium polyacrylate super absorbent resin, and 1 part of water, weighed in proportion and mixed in a concrete mixer It is evenly combined and sprayed on the surface of sand and dune that needs sand fixation to form a polymer sand fixation layer with a thickness of 3-6mm.

Embodiment 3

[0028] Example 3: Mix 1 part of Portland cement, 5 parts of sand, 0.08 parts of cationic emulsified asphalt, 0.08 parts of sodium polyacrylate super absorbent resin, and 0.5 parts of water, weigh them in proportion and mix them evenly in a concrete mixer, and spray them on On the surface of sand and dune that needs sand fixation, a polymer sand fixation layer with a thickness of 3-6mm is formed.

Abstract

The belongs to the field of compound material, and is especially one kind organic-inorganic sand fixing material for tackling desert. the sand-fixing polymer-cement material consists of cement in 1 weight portions, sand 5-10, water 0.5-1, cation emulsified asphalt 0.03-0.1, high water absorption sodium polyacrylate resin 0.02-0.1; and the mixture is sprayed in desert. The cement mortar is modified with black, heat insulating and water absorbing and maintaining cation emulsified asphalt and high water absorption sodium polyacrylate resin, so that the present invention has the features of high strength, high water absorbing and maintaining performance, high durance, high freeze thawing stability, high wind erosion and weather resistance, no environmental pollution, low cost, etc.

Description

Technical field [0001] The invention belongs to the field of composite materials, and specifically relates to an organic-inorganic chemical sand-fixing material mainly used for desert control. Background technique [0002] Mechanical sand fixation system, plant (biological) sand fixation system, and chemical sand fixation system are the three major sand fixation systems today. Among them, mechanical sand fixation can only be used as a temporary and auxiliary sand fixation method. Biological sand fixation technology is currently the most common technology in desert management, and it is also the best sand fixation method once and for all, but it is difficult to provide due to the harsh natural environment The basic elements that plants rely on for survival make trees the highest survival rate of only about 30%, with little effect, and in some places even no grass grows. Chemical sand fixation can be mechanized construction, simple and fast, especially suitable for areas lacking en...
