Problems solved by technology

[0002] The traditional putty mainly uses the powder material composed of inorganic cementitious material white cement or gray calcium and organic cementitious material. Before construction, it needs to be mixed and stirred on site. During the mixing process, the dust is very serious, which will cause serious damage to the health of construction workers and the indoor environment. influences
[0003] Today's interior wall decoration styles and styles are various. In order to achieve decorative effects and meet different shapes of coatings, it is a test for consumers' choices. Traditional putty only has the function of scraping and leveling, and it cannot meet the shape of various shapes. Performance requirements for construction
[0004] Traditional construction putty is generally made of powder, and then mixed with water on site. During the mixing process, there will inevitably be dust and other pollution. In addition, the existing paste putty needs about 5 hours after the painting is completed. Dry, the drying time is too long; in addition, after mixing the putty, it needs to be used up as soon as possible, because the existing putty is not easy to store after mixing, and it is prone to deterioration, resulting in unnecessary waste. Finally, the existing putty After the coating is completed, the toughness is not high, and fractures are prone to occur

Embodiment 1

[0029] Weigh 250g of water and 2g of bactericidal preservative respectively and add them to the container of the disperser. Nitrogen-containing compounds can choose hypochlorite, hypochlorite is a traditional bleaching agent, the available chlorine in it has a strong bactericidal effect, chlorine can invade into microbial cells, destroy enzyme proteins in cells, or inhibit Enzymes sensitive to oxidation, leading to the death of microorganisms. Hypochlorite has a killing effect on bacterial reproductive cells, spores, viruses, yeast, mold and other microorganisms. The bactericidal effect is enhanced under high temperature, high concentration, long time and low pH conditions. After mixing, Start the disperser, the stirring speed is 500--800r / min, and slowly add 1.5g of water-retaining agent hydroxypropyl methylcellulose and 19g of sodium bentonite while stirring, because sodium bentonite has very excellent swelling properties, bonding properties, adsorption, catalysis, thixotro...

Embodiment 2

[0033] The difference from Example 1 is that in this example, 300g of water is taken, and 1.5g of bactericidal preservative is used. Base bentonite 15g, defoamer 1.5g, propylene glycol 10g, polyvinyl acetate emulsion 100g, 200 mesh gypsum powder 200g, 325 mesh heavy calcium powder 339g, 800 mesh kaolin 30g, defoamer consists of mineral oil type defoamer and organic Silicon defoamer 1:1 prepared.

Embodiment 3

[0035] The difference from Example 1 is that 350g of water and 1g of bactericidal preservative are weighed respectively. In this example, the bactericide is selected from isothiazolinone derivative bactericide, 4g of water-retaining agent and 10g of sodium-based bentonite, and silicone defoaming agent Agent 2g, propylene glycol 12g, polyvinyl acetate emulsion 70g, 400 mesh ash calcium powder 200g, 325 mesh heavy calcium powder 351g.

[0036] Wherein, the water retaining agent is formed by mixing hydroxypropyl methylcellulose and / or hydroxyethyl methylcellulose bentonite at a ratio of 1:1.

Abstract

The invention discloses multi-model paste putty and a preparation method thereof. According to the technical scheme, the multi-model paste putty is characterized by being prepared from, by weight, 25-35% of water, 0.1-0.2% of a sterilization corrosion remover, 0.1-0.2% of a defoaming agent, 0.5-1.5% of a stabilizing agent, 0.5-2% of a water retaining agent, 7-15% of emulsion, 10-20% of a gelling material system and 35-55% of padding. Due to the fact that the stabilizing agent and the gelling material system are added, after mixing is performed completely, the dispersing effect of the components is quite good, and the quite excellent flexibility is achieved, the multi-model paste putty is not likely to go bad when stored for a long time, and raw material waste is avoided; when the multi-model paste putty is used for painting, due to the fact that the multi-model paste putty is stirred in a factory in advance, the multi-model paste putty can be used on site when a can is opened, powder mixing and stirring are not needed, raised dust generated when calcium carbonate is used is avoided, constructors and indoor environment are protected, the raw material of the water retaining agent hydroxypropyl methyl cellulose can meet the requirement of construction batch water retaining, and sodium bentonite can meet the requirement for shaping the three-dimensional modeling during construction.

Description

technical field [0001] The present invention relates to a kind of construction material, more specifically, it relates to a kind of paste putty for multi-modelling and its preparation method. Background technique [0002] The traditional putty mainly uses the powder material composed of inorganic cementitious material white cement or gray calcium and organic cementitious material. Before construction, it needs to be mixed and stirred on site. During the mixing process, the dust is very serious, which will cause serious damage to the health of construction workers and the indoor environment. influences. [0003] Today's interior wall decoration styles and styles are various. In order to achieve decorative effects and meet different shapes of coatings, it is a test for consumers' choices. Traditional putty only has the function of scraping and leveling, and it cannot meet the shape of various shapes. Construction performance requirements. [0004] Traditional construction pu...
