Abstract
A kind of mortar admixture and manufacture method thereof that is used for sand-cement slurry, make the sodium salt electrolyte solution of naphthalene sulfonation formal by naphthalene, formaldehyde, sulfuric acid, liquid caustic soda, add water soluble resin, water is heated to 95 ℃, all after the dissolving, cool to below 60 ℃, add sodium base silicone oil and urea again, ethylene glycol stirs evenly.This mortar auxiliary agent can improve the incorporation degree of sand-cement slurry, the intensity of refinforced cement mortar, can compound a part of flyash during application, replace the lime in the sand-cement slurry fully, therefore can reduce construction costs, improve construction environment, can reduce the mortar freezing point simultaneously, be convenient to winter construction, the mortar after the curing has waterproof, moisture barrier properties comprises.
Description
The invention belongs to a kind of admixture of building mortar.
In construction work, building mortar must mix with a certain amount of lime, with incorporation degree and the intensity that increases it, but in use, lime makes construction environment and workman's labor condition variation easily, present existing mortar auxiliary agent is as " TG glue ", " micro foam agent ", " lime essence " etc., and they all have the effect that replaces lime in mortar, but " TG glue " might make mortar strength that tangible reduction is arranged; And " lime essence " and " micro foam agent " have the function that the mortar strength of making improves and improve workability, but its plasticity is poor.
The purpose of this invention is to provide a kind of admixture that is used for sand-cement slurry, can replace the lime in the mortar fully, improve the incorporation degree and the intensity of sand-cement slurry, reduce construction costs, improve construction environment and workman's labor condition, can also make mortar have certain plasticity, so that construction.
Mortar admixture of the present invention is made the sodium salt electrolyte solution of naphthalene sulfonation formal by naphthalene, formaldehyde, sulfuric acid, liquid caustic soda, it is characterized in that: add water-soluble resin (PVA) and sodium base silicone oil, its weight percentage: NAPTHALENE FLAKES. (INDUSTRIAL GRADE (95% or refined naphthalene) 14～17%; Sulfuric acid (92～98%) 22～25%; Formaldehyde (36～37%) 12～15%; Liquid caustic soda (40%) 18～21%; Water-soluble resin 1.0～2.0%; Sodium base silicone oil 1.0～5.0%; Water 23～27%.
As the need winter construction, mortar admixture also can add urea 0.1～0.3%, ethylene glycol 0.1～0.4%.
The manufacture method of this mortar admixture is put into reactor with naphthalene; Be heated to 150 ℃, begin to stir, when temperature rises to 160 ℃, slowly add sulfuric acid, carry out sulfonation; Insulated and stirred 3 hours slowly adds water again when temperature drops to 95 ℃ then, be hydrolyzed; After this slowly add formaldehyde again, carry out condensation reaction; Insulated and stirred 5 hours cools to below 60 ℃ again, adds 40% liquid caustic soda PH=7～9 that neutralize, and promptly makes first liquid; Solid content remains on about 45%; It is characterized in that: second liquid is water-soluble resin to be added in the entry dissolve, and is heated to 95 ℃, all after the dissolving, cools to below 60 ℃, and adding urea, sodium base silicone oil, ethylene glycol stir evenly; First liquid and second liquid are mixed, and solid content 35% is finished product.
The present invention is made of two big components, i.e. (1), the sodium salt electrolyte solution of sulfonation formal how; (2), water-soluble resin, sodium base silicone oil and other mixture.
Wherein first kind of dispersant with high efficiency that component is a cement has been widely used in the concrete works, and it mainly acts on is the concrete early stage and later strength of diminishing and enhancing, and its effect in sand-cement slurry is with identical in concrete.
The effect of second kind of component is: water-soluble resin can improve the viscosity of mortar admixture, keeps the plasticity of stablizing and improve mortar of this agent, can replace the effect of lime in mortar fully.Add sodium base silicone oil, not only can increase the viscosity of mortar itself, and in the mortar solidification process, sodium base silicone oil can form the silanol key with the metal ion in the cement, therefore improved mortar cured strength and compactness, can make it have certain protection against the tide, fire resistance characteristic.For improving the freeze-proof of mortar admixture, can also add urea and ethylene glycol, can effectively reduce the freezing point of sand-cement slurry, be convenient to winter construction.
Advantage of the present invention is: the incorporation degree that can improve sand-cement slurry, the plasticity of refinforced cement mortar and intensity, when using behind compound a part of flyash, can replace the lime in the sand-cement slurry fully, therefore can reduce construction costs, improve construction environment and workman's labor condition, can reduce the mortar freezing point simultaneously, be convenient to winter construction, the mortar after the curing has waterproof, moisture barrier properties comprises.
Below in conjunction with drawings and Examples the present invention is described in detail:
Fig. 1 is a process flow diagram of the present invention.
Embodiment: (1) puts into 2000 liter reactors with 400 kilograms of NAPTHALENE FLAKES. (INDUSTRIAL GRADE, be heated to 150 ℃, begin to stir, when temperature rises to 160 ℃, slowly add 600 kilograms in sulfuric acid, insulated and stirred 3 hours, slowly add 100～150 kilograms in water (total acidity was decided when amount of water finished on sulfonation) when temperature drops to 95 ℃ then again, after water injection after, temperature is controlled between 95～110 ℃, slowly add 350 kilograms in formaldehyde, insulated and stirred 5 hours cools to below 60 ℃ then, all moves in the neutralization tank, be neutralized to pH value 7～9 with liquid caustic soda, solid content remains on about 45%;
(2) 25 kilograms of water-soluble resins (PVA) are put in the 500 liter reactors, added 500 kg of water simultaneously, be heated to 95 ℃, begin to stir, after PVA is all dissolved, cool to below 60 ℃, add 25 kilograms of dimethyl-silicon sodium alkoxide, as consider winter construction, add again after 5 kilograms of 10 kilograms of ethylene glycol, urea mix, move in the neutralization tank mixing, promptly become finished product, solid content 35%.
When using, 100 kilograms of cement add 2～5 kilograms of mortar admixtures, 20～50 kilograms of flyash, 500 kilograms of sands, stir, and can use.
