Abstract
The invention provides a composite soil body modifier and a preparation method thereof. The composite soil body modifier is prepared by blending polyvinyl alcohol, cellulose ether, lignin fibers, a surfactant and water in a certain proportion by taking acrylic acid and a vinyl sulfonate polymeric product as a main body. The composite soil body modifier provided by the invention is a composite modifier of an anion and cation compound surfactant and a high polymer. The composite soil body modifier acting on a soil body changes the surface properties of the soil body and cements particles of the soil body. The soil body is grinded and compactly moulded to form a high strength plate which can be widely applied to the fields of roads, construction materials and the like. In addition, the composite soil body modifier which takes solid wastes such as construction waste or tailings are an application object facilitates environmental protection.
Description
Technical field
The present invention relates to a kind of soil body properties-correcting agent, be specifically related to a kind of preparation method of the compound soil body properties-correcting agent for treatment of soft foundation, foundation works and civil construction material produce and the compound soil body properties-correcting agent making thereof.
Technical background
20 beginnings of the century, abroad some economically developed countries just start the research to soil body modification technology, and soil body modification the 1950's has formed a comprehensive cross discipline.Over nearly 20 years, soil body modification technology is rapidly developed, Chinese scholars is from different engineering application purposes, development and to have developed a series of soil bodys material modified, make it to develop into complexity, comprehensive polymorphic type chemical substance by simple, single inorganic bond material, for the modification of all kinds soil body.
China's soil body properties-correcting agent research and development are started late, and compared with foreign enterprise, still have larger gap.But see on the whole, external and domestic soil body properties-correcting agent all exists some defects, as single variety properties-correcting agent can only adapt to, the soil body, the stable period of certain particular type is short, construction restrictive condition is many etc.This is that restriction soil body properties-correcting agent is widely used principal element, is also the emphasis of studying in the industry the coming years.Zwitterion compound surfactant is combined with Polymers Phase, can significantly promotes the performance of soil body properties-correcting agent, have effective object extensively, simple process, successful, input cost is low and be conducive to the multiple advantages such as environment protection, this route has no report.
Summary of the invention
The object of the invention is to provide a kind of compound soil body properties-correcting agent for treatment of soft foundation, foundation works and civil construction material produce and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:
A preparation method for compound soil body properties-correcting agent, is characterized in that comprising the steps:
(1) Acrylic Acid Monomer and sodium vinyl sulfonate monomer are joined in reactor, take ammonium persulphate as initiator, polyvinyl alcohol is stablizer, and in the aqueous solution, polyreaction obtains the polymerisate A of formula;
(2) configuration surface promoting agent compound system;
(3) slurry polymerisate A and tensio-active agent and certain proportion ether of cellulose, lignin fibre and water are mixed and made into compound soil body properties-correcting agent.
Described compound soil body properties-correcting agent and preparation method thereof, is characterized in that described Acrylic Acid Monomer, sodium vinyl sulfonate, ammonium persulphate, polyvinyl alcohol and aqueous solvent mass ratio are 2:(1-1.5): (0.1-0.5): (0.8-1.2): (9-15).
Described compound soil body properties-correcting agent and preparation method thereof, is characterized in that described tensio-active agent is the compound system of alkyl diphenyl ether disulphonic acid sodium and dodecyldimethyl hydroxyethyl ammonium chloride, and composite mol ratio is 1:2-3.
The preparation method of described compound soil body properties-correcting agent, is characterized in that described polymerisate A, ether of cellulose, lignin fibre, tensio-active agent and quality than being (8-12): (3-7): (4-7): (1-2): (72-84).
The compound soil body properties-correcting agent that present method makes.
The synthetic of polymerisate A involved in the present invention can represent with chemical equation below:
Surfactant compound system in the present invention comprises double-hydrophilic group anionic surfactant alkyl diphenyl ether disulphonic acid sodium and quaternary ammonium salt cationic surfactant dodecyldimethyl hydroxyethyl ammonium chloride, belong to Catanionic surfactant mixed system, under finite concentration, there is strong interaction, aquation repulsion weakens, molecular thermalmotion aggravation, produce synergistic effect, greatly reduce surface tension.Soil body modifier system acts on after the soil body, through charge-exchange effect, destroy the adsorbed film of water of the soil body completely, in properties-correcting agent, contained superpolymer component by soil body granular cementation together, by rolling moisture, discharge, degree of compactness uprises, permeability coefficient declines, and forms high-intensity plate, and this reaction is forever irreversible.The soil body changes hydrophobic nature into from wetting ability, and weather resistance is good.
Beneficial effect of the present invention:
(1) the present invention itself does not pollute environment, and has the performance of easily disperseing in the soil body, and construction technology is easy;
(2) properties-correcting agent changes this body structure of the soil body, reduces moisture content in the soil body, improves water stability energy, and the soil body is changed into solid column, can be widely used in the fields such as road, material of construction; (3) subject of this properties-correcting agent is except traditional building material, and the solid waste such as building waste and mine tailing of can also dissolving, are conducive to environment protection.
For a better understanding of the present invention, by following instance, describe:
Embodiment 1:
Initiator ammonium persulfate 1g is dissolved in 80g distilled water, and letting nitrogen in and deoxidizing after dissolving slowly drips Acrylic Acid Monomer 13g, sodium vinyl sulfonate 7g and stablizer polyvinyl alcohol 7g, and dropping temperature remains on 65-70 ℃.Dropwise rear 94 ℃ of backflow 1h and complete reaction;
