Abstract
The coagulation-regulating gelatinizer for prestirred mortar has the basic components including modified naphthalenesulfonic acid-formaldehyde condensate as water reducing agent, composite coagulation-regulating agent, methyl cellulose ether as thickener, smectite powder as water maintaining agent, and flyash and slag as carrier. Its production method includes mixing, weighing, packing and other steps. With the functions of reducing water effectively, regulating coagulation period, maintaining thickness, preventing separation, etc., the coagulation-regulating gelatinizer may be used widely in producing prestirred mortar for building engineering. The utilization of flyash and slag is favorable to comprehensive utilization of resource and environment protection.
Description
Technical field: the present invention relates to a kind of material of construction, specifically be meant necessary additive and production technique thereof in a kind of premixing mortar production.
Background technology: because the development of construction industry, sand-cement slurry has realized specialized production.Sand-cement slurry is divided and is delivered to each building site earlier by behind special manufacturer's premixing.Generally when carrying out the mortar premixing, must add various additives,,, overcome demixing phenomenon, keep moisture, prevent to lump too early etc. as adjusting time of coagulation to adjust the various performances of mortar.But no water reducer composition in the general additive, its diminishing ability is relatively poor.
Summary of the invention:
The present invention proposes a kind of coagulation-regulating gelatinizer for premixed mortar; by in additive, adding high-effect water reducer; can be under the prerequisite of ensuring the quality of products; reduce the cement consumption in the premixing mortar significantly; and make the flyash that in mortar, mixes power plant in a large number and the slag powders of steel mill become possibility; so not only can reduce material cost greatly, and help flyash and scoriaceous comprehensive utilization, help the comprehensive utilization of resource and the protection of urban environment.The present invention also proposes the production technique of described coagulation-regulating gelatinizer for premixed mortar.
A kind of coagulation-regulating gelatinizer for premixed mortar of the present invention, its major ingredient are high efficiency water reducing agent, compound agent of regulating coagulating, thickening material, water-holding agent and carrier.Wherein water reducer adopts the modified naphthalene sulfonate formaldehyde condensate of the present invention's original creation, and its diminishing can improve more than 100% by the common water reducer of force rate, can significantly reduce cement consumption; The compound agent of regulating coagulating of special preparation adopts saccharification dicalcium and citrate of lime, its effect is to make mortar be " dormancy " state in transportation and its cement of lay up period, hydration reaction speed is extremely slow, and after mortar uses, minimizing along with moisture in the mortar, hydrated reaction of cement becomes again normally, and can guarantee the working strength of mortar; Thickening material adopts methyl cellulose ether, water-holding agent adopts montmorillonite powder, selected thickening material and water-holding agent make premixing mortar in transportation and lay up period layering, segregation not take place, and the damage control of mortar consistency has guaranteed the workability when premixing uses in 20%.
The present invention has efficient diminishing, regulate time of coagulation, protect thick, advantages such as anti-bleeding, anti-segregation, anti-layering, reduction mortar material cost, can be widely used in the production and supply of premixing mortar in the construction work, both be suitable for masonry mortar, also be suitable for motar and ground mortar.
The production technique of coagulation-regulating gelatinizer for premixed mortar of the present invention is:
(1) join A material: with water reducer, adjustable solidification agent, thickening material, water-holding agent analytical study respectively, and by than
Example is mixed;
(2) the A material that mixes is mixed by proportioning with carrier;
(3) check;
(4) weighing, pack packing.
Description of drawings:
Fig. 1 is the synthesis process flow diagram of modified naphthalene sulfonate formaldehyde condensate of the present invention.
Wherein: 1 feedstock analysis, 2 sulfonation, 3 hydrolysis, 4 condensations, 5 neutralizations, filtration, 6 dryings, 7 checks, weighing, packing.
The specific embodiment:
Coagulation-regulating gelatinizer for premixed mortar of the present invention, its basic composition is by weight percentage:

All the other are carrier.
Carrier can adopt flyash or steel mill's slag etc.
The degree of saccharification dicalcium and calcium citrate has been about equally in the described compound agent of regulating coagulating.
The key technical indexes of coagulation-regulating gelatinizer for premixed mortar of the present invention is:
Water reducing ratio of cement mortar % 15-25
Mortar coagulation time h 〉=24
The thick long mm 70-110 of mortar
Coursing degree of mortar mm≤20
28 days strength ratio % 〉=100 of mortar Chloride ion content %≤0.40 PH value 5.5-1.5 The appearance off-white powder. The technological process of production of coagulation-regulating gelatinizer for premixed mortar of the present invention is: (1) join A material: with water reducer, adjustable solidification agent, thickener, respectively analytical control of water-loss reducer, and by than
Example is mixed; (2) carrier and the A material that mixes are mixed in proportion; Namely earlier outstanding with pouring into after the carrier weighing
In the arm cone and screw mixer, the A material that mixes is poured in the mixer, start mixes again
Evenly; (3) check; (4) weighing, pack packing. The synthesis technique flow process of modified naphthalene sulfonate formaldehyde condensate of the present invention is as shown in Figure 1: (1) feedstock analysis; (2) sulfonation: will be through refined naphthalene and the sulfate radical SO of rectifying to 98%-99%4 2-Carry out sulphur after the analytical control
Change reaction, generate the sulfonating reaction thing, its mole ratio is naphthalene: sulfate radical=1: 1.5, temperature is
155-165 ℃; (3) hydrolysis: with the reaction that is hydrolyzed in reactor of sulfonating reaction thing, its mole ratio is sulfonation
Reactant: water=1: 11.5, acidity is controlled at 24%-27%, and temperature is 95-100 ℃; (4) condensation: hydrolysate and formaldehyde are carried out condensation reaction, and its mole ratio is hydrolysate: formaldehyde
=1: 0.7-1.0, reaction pressure is 1 atmospheric pressure, reaction temperature is 110-115 ℃, and is anti-
