Description
Technical field
The invention belongs to ecological soil stabilizer goods of organic chemical industry's class and preparation method thereof.
Background technology
Soil stabilizer is as a kind of novel solidify material, has plurality of advantages such as applied widely, that solidification effect good, gather materials on the spot, cheap, construction and maintenance are convenient, and some developed countries are applied in the world.The research and development of soil stabilizer at present are mainly based on developed countries such as the U.S., Japan, Canada, and the domestic research and development that mainly concentrate on the mineral-type soil stabilizer, also there is a big difference aspect organic class stablizer with abroad.The shortcoming of mineral-type soil stabilizer is that the early strength of solidified earth is not high, easily forms desciccation crack, influences its water stability and structural; The soil that applies behind the mineral-type soil stabilizer does not generally have ecological functions, can't afforest, and does not reach the requirement of landscaping.
Summary of the invention
The present invention seeks to: propose a kind of ecology, efficient, safe organic class ecological soil stabilizer and preparation method thereof.Especially a kind of soil stabilizer goods with ecological functions and preparation method thereof are mainly used in soil conservation, antiscour erosion, slope protection and the ecological afforestation etc. of soil-slope, can be used as the domatic ecological protection material of all kinds of soil-slopes.
Technical solution of the present invention is: ecological soil stabilizer, and its prescription is:
Water or deionized water 180-220 weight part
Comonomer 1: vinyl acetate 100-140 weight part
Comonomer 2: methyl methacrylate or with comonomer 3 5-20 weight parts
Comonomer 3: acrylate 5-20 weight part
Polyvinyl alcohol 8-15 weight part
Emulsifier sodium lauryl sulfate or with OP 2-4 or be the 2-4 weight part
Initiator (persulphate) 0.5-2 weight part
The present invention also adds in addition:
Comonomer 4 (tertiary ethylene carbonate) 10-25 weight part
Emulsifying agent 2 (OP-10) 2-5 weight part
Improvement of the present invention also comprises the interpolation following compositions:
Dispersion agent (CH-10S) 1-2 weight part
Softening agent (dibutyl phthalate) 10-20 weight part
Buffer reagent (sodium bicarbonate or ammoniacal liquor) 3-5 weight part
Pigment 0-40 weight part
Preparation method of the present invention is: earlier polyvinyl alcohol is dissolved fully water or deionized water (by above-mentioned weight part, down with) and polyvinyl alcohol mixing; The 1/10-1/7 pre-reaction of adding persulphate and comonomer 1 weight part 20 minutes; In 2-3 hour, splash into reaction system with the comonomer 1 of remainder and comonomer 2 or with comonomer 3 or after adding comonomer 4 uniform mixing more again; Dripping the back keeps 60-73 ℃ temperature to continue reaction 30-60 minute; After removing the residual monomer processing, cool the temperature to 50-55 ℃ of adding softening agent, dispersion agent, buffer reagent, stablizer and fully stir evenly postcooling, promptly obtain goods of the present invention to the room temperature discharging.As the needs colored article, can in these goods, add pigment dyestuff, grind with dispersion machine and make.
Characteristics of the present invention are: the present invention has good environment fitness, and the present invention meets " environmental labelling product technical requirements " basic demand (HJB2004-94), is environmentally friendly product.These goods are emulsion liquid, its principal character for it contact with the cohesive soil particle have an effect after, can obviously improve the water stability and the intensity of soil particle; Can strengthen native scour resistance after using this material, have moisture-keeping functions simultaneously, can promote plant-growth.These goods are neutral, have nontoxic, free of contamination advantage, and used water is pressed the arbitrary proportion dilution, and is easy to use, are very suitable for the slope protection of soil-slope.Goods of the present invention have been applied to peaceful Huaihe River motorway swelling soil cut slope ecological protection engineering, have obtained the effect of good soil stabilization and ecological afforestation.
Embodiment
Goods of the present invention are mainly used in the ecological revetment of soil-slope.The formulation Example of ecological soil stabilizer:
Water or deionized water 180-220 weight part, 180 or 220 all can; Comonomer 1: vinyl acetate 100-140 weight part, 100 or 140 all can; Comonomer 2: methyl methacrylate: the 5-20 weight part, 5 or 20 all can; Or add comonomer 3 again: acrylate, the 5-20 weight part, 5 or 20 all can; Polyvinyl alcohol: the 8-15 weight part, 8 or 15 all can; Emulsifier sodium lauryl sulfate or with the OP:2-4 weight part, 2 or 4 all can; Initiator (Potassium Persulphate): the 0.5-2 weight part, 0.5 or 2 all can; The present invention also adds in addition: comonomer 4 (tertiary ethylene carbonate): the 10-25 weight part, and 10 or 25 all can; Emulsifying agent 2 (OP-10), 2-4 weight part 2 or 4 all can; Also can add following compositions: dispersion agent 1-2 weight part; Softening agent (dibutyl phthalate), the 10-20 weight part; Buffer reagent 3-5 weight part.
The preparation method: earlier with water or deionized water (by above-mentioned weight part, down with) and polyvinyl alcohol 80 ℃ of stirrings, polyvinyl alcohol is dissolved fully; After its temperature is reduced to 68-73 ℃ of 1/10-1/7 pre-reaction that adds Potassium Persulphate and comonomer 1 weight part 20 minutes; To in 2-3 hour, splash into reaction system behind the comonomer 1 of remainder and comonomer 2, comonomer 3, comonomer 4 uniform mixing again; Dripping the back keeps 68-73 ℃ temperature to continue reaction 30-60 minute; After removing the residual monomer processing, cool the temperature to 50-55 ℃ of adding softening agent, dispersion agent, buffer reagent and fully stir evenly postcooling to the room temperature discharging.
Use with following step goods preparation back:
(1) the domatic leveling stage: no matter be the artificial side slope that mechanical equivalent of light excavation forms, still natural slope because a variety of causes often causes domatic soil erosion, planeness low, causes the deficiency on whole vision of side slope and the sense organ, therefore also make troubles, at first tackle domaticly manually flattening to construction;
(2) the ferti-seeding stage: combine better with side slope protection in order to make greening side slope, it is very necessary imposing grass seeds and fertilizer on the side slope after the leveling;
(3) dilution stage:, just use after at the practical situation of soil-slope these goods being diluted by certain working concentration usually because these goods self have certain viscosity;
(4) the sprinkling stage: these goods dilution back evenly is sprayed at the side slope surface of spreading grass seeds and fertilizer by certain unit surface sprinkling amount, sprays and adopt machinery to spray usually;
(5) the side slope maintenance stage:, therefore in for some time before and after the seed germination, need regularly side slope is carried out maintenance (as water, insulation etc.) because seed germination needs certain natural condition such as temperature, moisture and sunlight;
(6) the side slope protection recruitment evaluation stage: after these goods use, ecological revetment effects such as the scour resistance of side slope, soil erosion amount, domatic destructiveness, vegetation growth situation are assessed.
