Description
Technical field
The invention belongs to land technical fields, and in particular to a kind of soil stabilizer.
Background technology
Soil stabilizer is a kind of new soil curing material, it by changing the permutation and combination of soil molecule, point
The intransitable nethike embrane of water is formed between son, the viscosity of soil itself is recycled to reach stable soil, bearing capacity of soil is improved, prevents
Water penetration accelerates the purpose of soil natural petrochemical industry.Therefore the use of soil stabilizer is to ecologies such as soil erosion, desertifications
The solution of environmental problem can act as good effect.To in the 1980s, people have synthesized class high score to existing
Sub- soil texture stabilizer has sufficient understanding.By 1996, polyacrylamide as soil stabilization water-retaining agent in the U.S.
Substantial amounts of popularization and application are obtained.At the same time, for the considerations of reducing cost and the friendly property of environment etc., people are also to day
The soil stabilization effect of right macromolecule modified product is studied；And by the application study of polymeric soil structural stabilizing agent by
Step expands to Desert Control, exposed soil is fixed, engineering construction etc..
Domestic polymeric soil stabilizer products many at present are all that two kinds or several chemical materials are carried out simply
Mixing is so difficult that stabilizer is targetedly improved according to the improved effect of Modified soil.And to the soil of different soil properties
The research of earth stabilizer also lacks specific aim, deep not enough to the research of its mechanism of improvement.
A kind of Chinese patent literature " efficient soil stabilizer (Authorization Notice No.：CN103864391B) " disclose a kind of high
Soil stabilizer is imitated, the stabilizer is in terms of parts by weight, including following material：10-70 parts of flyash, 10-50 parts of cement, gypsum
10-30 parts of powder, 1-20 parts of aluminum sulfate, 1-5 parts of SILICA FUME, 1-10 parts of modification infusorial earth, 1-10 parts of crushed crude pearlite, titanium oxide 1-10
Part.The soil stabilizer can be widely used for riverbed sludge dredging, and the laying of park stroll road and rural area dirt road improves soil
Deng having superpower foul smell adsorption capacity, excellent water-retaining property and water penetration, however there is unconfined compressive strength, water are steady
The problems such as qualitative and scour resistance is relatively low.
The content of the invention
It is an object of the invention to provide a kind of soil stabilizer, to solve in a kind of Chinese patent literature " efficient soil
Stabilizer (Authorization Notice No.：CN103864391B on the basis of soil stabilizer disclosed in) ", how to optimize component, dosage etc., carry
Unconfined compressive strength, water stability and the scour resistance in high soil.
For solution more than technical problem, the present invention uses following technical scheme：
A kind of soil stabilizer, in units of parts by weight, including following raw material：Modification infusorial earth, flyash, cement, stone
It is cream powder, crushed crude pearlite, titanium oxide, surfactant, tetramethylammonium hydroxide, polyacrylamide, hydroxypropyl methyl cellulose, poly-
Carboxylate, polyoxyethylene octane alkylphenol ether, acetic acid isopropyl alkene-ethyl acetic acid propylene ester copolymer；
The hydroxypropyl methyl cellulose, polycarboxylate, polyoxyethylene octane alkylphenol ether, acetic acid isopropyl alkene-ethyl

Preferably, the glass fibre, polycarboxylate, polyoxyethylene octane alkylphenol ether, acetic acid isopropyl alkene-ethyl second
Acid propylene ester copolymer weight ratio is 1.8:1.1:0.9:1.
The present invention also provides a kind of preparation methods of soil stabilizer, comprise the following steps：
S1：Diatomite is toasted into 4-5h under 500-520 DEG C of temperature temperature, fast quickly cooling in a low temperature of being subsequently placed in 5-10 DEG C
But, the distilled water stirring of 2 times of amounts is added, 100-120 DEG C is raised the temperature to, adds in the sulfuric acid of 20%-30% while stirring,
It after when reaction 3-5 is small, is washed with water, filters, you can obtain modification infusorial earth.
S2：By modification infusorial earth, flyash, cement, land plaster, crushed crude pearlite, titanium oxide, surfactant, tetramethyl
Ammonium hydroxide, polyacrylamide, hydroxypropyl methyl cellulose, polycarboxylate, polyoxyethylene octane alkylphenol ether, acetic acid isopropyl
Alkene-ethyl acetic acid propylene ester copolymer mixed dissolution, stirs evenly, is fully reacted under conditions of 50-80 DEG C, and the reaction time is
4-6h。
The invention has the advantages that：
(1) by the data of embodiment 1-4 and comparative example 6 as it can be seen that using the soil of embodiment 1-4 soils stabilizer without lateral spacing
Compression strength, water stability and scour resistance significantly improve；Simultaneously by the data of embodiment 1-4 as it can be seen that embodiment 4 is optimal reality
Apply example.
(2) by embodiment 4 and the data of comparative example 1-6 as it can be seen that hydroxypropyl methyl cellulose, polycarboxylate, polyoxyethylene
Octane alkylphenol ether, acetic acid isopropyl alkene-ethyl acetic acid propylene ester copolymer play synergistic effect in soil stabilizer, collaboration
Soil unconfined compressive strength, water stability and scour resistance are improved, this may be：
1) hydroxypropyl methyl cellulose can improve the gelling property of stabilizer, and hydroxypropyl methyl cellulose, polyoxyethylene are pungent
Alkylbenzene phenolic ether generates electrochemical reaction with grogs surface ionization, can form the corpus fibrosum with good gelatification, this
Neighboring soil particle can be together in series by kind of corpus fibrosum, so as to improve the tensile capacity of soil, even at dampness,
It can make soil that there is good tensile capacity, so as to improve the unconfined compressive strength of soil, water stability and scour resistance, this
There is very important effect to soil stability.
2) polycarboxylate has good hydrophobic performance, can tightly hold hydrone when meeting water, form good absorption
Water layer promotes soil particle to uphold and increases the distance between grogs, as adsorbed water layer is constantly thickening, can improve soil
Stability changes the hydrophily of grogs, soil is made to have better hydrophobicity, therefore polycarboxylate can enhance between soil particle
Water stability and scour resistance.
3) be used in combination can be in soil for polyoxyethylene octane alkylphenol ether and hydroxypropyl methyl cellulose, polycarboxylate
Intergranular forms certain netted membrane structure, enhances the binding strength between soil particle, so as to improve the unconfined compressive strength of soil,
Water stability and scour resistance.
4) acetic acid isopropyl alkene-ethyl acetic acid acrylic ester and hydroxypropyl methyl cellulose, polycarboxylate, polyoxyethylene octyl
Phenol ether copolymer acts on soil particle so that power, the intermembranous viscous force of aquation and capillary water are acted between soil particle
Surface tension synergy and cause to produce cohesive force between particle, the contact force between soil particle is increased, between soil particle
The surface tension of capillary water is also remarkably reinforced, so as to improve the intensity unconfined compressive strength of soil, water stability and resist
Erosion.
(3) hydroxypropyl methyl cellulose, polycarboxylate, polyoxyethylene octane alkylphenol ether, acetic acid isopropyl alkene-ethyl acetic acid
Propylene ester copolymer is as reinforcement system, by controlling hydroxypropyl methyl cellulose, polycarboxylate, polyoxyethylene octyl phenol
Ether, acetic acid isopropyl alkene-ethyl acetic acid acrylic ester copolymer weight ratio are (1.2-2.5)：(0.9-1.4)：(0.5-1.2)：(0.6-
