Abstract
The invention discloses a kind of preparation methods of degradable sand-consolidating agent, belong to sand-consolidating agent field.The present invention takes peat soil, glucose and water to be put into container and is uniformly mixed standing, and dried object is collected in spray drying, carries out ball milling, and sieving particle is collected in sieving；Acetone, Isosorbide-5-Nitrae butanediol, L lactides and dibutyl tin laurate are put into reactor, using carbon-dioxide protecting, temperature reaction is cooled to room temperature, and is collected reaction mixing, and carry out recycling acetone, is collected residue；Residue, toluene, trimethylol-propane trimethacrylate, toluene di-isocyanate(TDI), sieving particle and catalyst are put into reaction kettle and are stirred, triethanolamine heating is added and continues to stir, be cooled to room temperature, discharge, collect out material；Material will be gone out, catalyst is recovered by filtration, then carry out rotary evaporation recycling toluene, and collected rotation residue, rotation residue, cholla gum and biologic grain are uniformly mixed to get degradable sand-consolidating agent.
Description
Technical field
The invention belongs to sand-consolidating agent fields, and in particular to a kind of preparation method of degradable sand-consolidating agent.
Background technology
Desertification is the significant Global ecological environment problem that current mankind faces, and annoyings existence and the hair of human society
Exhibition, and China is one of the country seriously endangered by desertification.Desert and desertification land area are up to 1,490,000 km2, wherein desert
Change land area up to 33.4 ten thousand km2, this brings serious influence to industrial and agricultural production, people's lives and health, without
The sandstorm of disconnected aggravation and the extension of sandy land more make ecological environment make the matter worse, and the existence for swallowing the Chinese nation is empty
Between, cause great harm to national economy and social development.Bordering on area in desert and desert is also often accompanied by high wind simultaneously
The serial ecological problems such as drift sand, earth's surface arid and soil erosion.Thus a series of agriculture and forestry problems caused, seriously hinder green
The growth and development for changing plant and crops causes to be short of seedling, the underproduction and phenomena such as death, wastes large amount of land resources and valuable water
Resource.
There are three ways to tackling quicksand, i.e. mechanical sand fixation, chemical sand-fixing and vegetative sand control.Sand is such as arranged in mechanical sand fixation
Barrier, straw checkerboard barrier etc., feature is quick, but puts into larger, unsuitable a wide range of use；Vegetative sand control is mainly at the edge of the desert
Or innerland plants shelter-forest or carries out plant skinning on Shamian Island, reduces the wind speed in desert, prevents desert from playing sand, and then reach
The purpose fixed the sand.Result of study of defending and controlling sand both at home and abroad shows in every prevention technique measure, with controlling sediment by plant using the most
Generally.But severe for natural conditions, by the place that drift sand infringement is serious and part is needed to fix the sand rapidly, vegetative sand control exists
It is difficult to play a role in short-term, or even totally by dust storm deflation.Chemical sand-fixing refers on desertification land surface layer using organic
Or inorganic materials for stabilizing sandy soil, to improve the stability and water-retaining property of sandy soil, or desalting processing is carried out to wetland with saline-alkaline, to
Achieve the purpose that improvement and Desert Control soil.The advantages of Techniques For Chemical Control is easy construction, at low cost, quick, can
Rapid improvement desertification land, good water and soil condition is created for plant growth, improve ecological environment engineering construction quality and
Efficiency.Therefore sand-consolidating agent due to have the function of it is dust-proof, fix the sand and be widely used.Sand fixation material used by sand-consolidating agent at present
There are emulsified asphalt, phenolic resin, Lauxite, polyacrylamide, styrene-butadiene latex etc., although the mesh checked winds and fixed drifting sand can be played
, but all it is organic polymer product, their own is all difficult to degrade in nature, can be polluted to desert area,
This limits the application of sand-consolidating agent to a certain extent.
Invention content
The technical problems to be solved by the invention：It is mostly organic polymer product for current sand-consolidating agent, itself is difficult to
The problem of degrading, being polluted to desert area in nature, the present invention provides a kind of preparation sides of degradable sand-consolidating agent
Method.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of preparation method of degradable sand-consolidating agent, the preparation method include the following steps：
（1）In mass ratio 3：1：2, it takes peat soil, glucose and water to be put into container and is uniformly mixed, seal and hold at 40 ~ 45 DEG C
Device is stood, and dried object is collected in spray drying, carries out ball milling, and sieving particle is collected in sieving；
（2）It counts in parts by weight, takes 100 ~ 110 parts of toluene, 70 ~ 80 parts of acetone, 50 ~ 60 parts of trimethylol propane trimethyl propylene
