Description
Technical Field
The invention relates to the technical field of waterproof putty, in particular to putty paste with high waterproof performance and a preparation method thereof.
Background
In recent years, the living standard of people is continuously improved, meanwhile, the decoration in the home is more and more emphasized, the wall decoration is an important decoration link, in order to enable the decoration to be better, high-grade paint can be selected, after the high-grade paint is selected, priming paint putty of the high-grade paint needs to be perfect, the water resistance of the putty is the most important index, the water cannot be soaked in the home, but water vapor exists in the air forever, the wall surface is exposed in the air, the wall surface cannot be corroded by the water vapor anytime and is good in water resistance, the service life is long, the poor water resistance means that the service life is short, the non-waterproof putty is damaged to the greatest extent, the wall surface is short in service life, and the indoor decoration is easy to hollowly bulge, peel and crack, so that great hidden danger is brought to the indoor decoration.
Disclosure of Invention
The invention aims to solve the technical problems of high stability and good water resistance and provides a putty paste with high water resistance and a preparation method thereof.
The technical scheme adopted by the invention is as follows: s1, adding heavy calcium powder and alkali swelling thickener into deionized water, and stirring to be uniform, wherein the ratio of the heavy calcium powder to the alkali swelling thickener to the deionized water is 3:1: 0.01;
s2, adding ash calcium powder, synthetic acrylic emulsion pre-pulping, a wetting dispersant, hydroxypropyl methyl cellulose and a water-based adhesion promoter into a stirrer continuously in the previous step, and stirring for 30-60min at a rotating speed of 200-300 r/min, wherein the ratio of the ash calcium powder, the synthetic acrylic emulsion pre-pulping, the wetting dispersant, the hydroxypropyl methyl cellulose and the water-based adhesion promoter is 10:2:0.5:0.5: 1;
and S3, slowly adding the organic silicon defoaming agent, the formaldehyde-free preservative, the calcium carbonate and the moisturizing lubricant in the stirring process, and continuously stirring at the rotating speed of 50-100r/min for 30-60min to obtain a white pasty product, wherein the ratio of the organic silicon defoaming agent to the formaldehyde-free preservative to the calcium carbonate to the moisturizing lubricant is 1:3:6: 3.
In the step 1, the alkali swelling thickener is an associated alkali swelling thickener, and a molecular chain of the alkali swelling thickener has carboxylic acid groups and presents a low pH value.
In the step 2, the synthesized acrylic emulsion pre-pulping is prepared from acrylic emulsion, porous starch and an antiseptic and mildew-proof agent.
The main component of the acrylic emulsion is methyl acrylate, and the auxiliary agents in the acrylic emulsion comprise an emulsifier, an initiator, a protective adhesive and a wetting agent.
In the step 2, the main component of the aqueous adhesion promoter is butyl glycol ether, and the molecular formula of the butyl glycol ether is C6H14O 2.
The porous starch is a mixed raw material formed by mixing corn starch and cassava starch.
The raw material particle size of the porous starch is 400-1000 meshes.
Compared with the prior art, the invention has the advantages that: the invention uses the ethylene glycol monobutyl ether as the main component in the aqueous adhesion promoter, can increase the adhesion, the adhesive force and the bonding force of the putty, can greatly improve the adhesion between the high-grade paint and the bottom layer putty, obviously improves the moisture resistance, the salt spray resistance and the heat resistance of the paint, ensures that the putty has good storage stability and long-acting property, adds the associated alkali swelling thickener and greatly improves the water resistance.
