Example Embodiment

[0029] Example 1:

[0030] The ratio of each component:

[0031] The ratio (weight ratio) of each raw material of component A is: acrylic emulsion 60%, water-based polyurethane emulsion 20%, filler 10%, auxiliary 1%, water 9%;

[0032] The ratio (weight ratio) of each raw material in component B is: Portland cement 80% activated calcium carbonate 20%.

[0033] The preparation method is as follows: add acrylic emulsion and water into the reaction kettle, heat to 65~75℃, then slowly add water-based polyurethane emulsion, keep and control the stirring time for 30 minutes, then cool down to room temperature, add auxiliary sodium benzoate, BYK- 33 Defoamer, activated calcium carbonate, after stirring evenly, testing, wrapping, and preparing the A component. Portland cement and activated calcium carbonate are proportioned by weight, accurately weighed, stirred evenly in a mixer, tested, and packaged to prepare component B. During construction, the A and B components should be m...

[0034] Example 2:

[0035] The ratio (weight ratio) of each raw material of component A is: acrylic emulsion 70%, waterborne polyurethane emulsion 10%, filler 10%, auxiliary 3%, water 7%;

[0036] The ratio (weight ratio) of each raw material in component B is: fly ash cement 90% fly ash 10%.

[0037] The preparation method is as follows: add acrylic emulsion and water into the reaction kettle, heat to 65~75℃, then slowly add water-based polyurethane emulsion, keep the stirring time for 30 minutes, then cool down to room temperature, add auxiliary sodium benzoate, defoaming agent and active calcium carbonate, after stirring evenly, testing, wrapping and transferring to prepare the first component. The cement and fly ash are proportioned by weight, accurately weighed, stirred evenly in a mixer, tested, and packaged to prepare component B. During construction, the A and B components should be mixed evenly in a ratio of 1:1 by weight, and the mixed waterproof coating must be us...

[0038] Example 3:

[0039] The ratio (weight ratio) of each raw material of component A is: styrene-acrylic emulsion 70%, water-based polyurethane emulsion 15%, filler 5%, auxiliary 1%, water 9%;

[0040] The proportion (weight ratio) of each raw material in component B is: fly ash cement 70% fly ash 30%.

[0041] The preparation method is as follows: adding styrene-acrylic emulsion and water into a reaction kettle, heating to 65-85° C., then slowly adding aqueous polyurethane emulsion, keeping the stirring time under control for 30 minutes, then cooling to room temperature, adding sodium benzoate and defoaming agent , Activated calcium carbonate, after stirring evenly, testing, wrapping, and preparing the first component. The fly ash cement and fly ash are proportioned by weight, accurately weighed, stirred evenly in a mixer, tested, and packaged to prepare component B. During construction, the A and B components should be mixed evenly in a ratio of 1:1.5 by weight, and the...

Abstract

The invention discloses a water-based acrylic waterproof paint and a preparation method thereof. According to the invention, high-molecular materials such as water-soluble acrylic acid and water-soluble polyurethane are adopted as main bodies, and formulation is carried out with a double-component form, such that a chemical reaction is carried out, and the waterproof paint is prepared. The paint is suitable to be used in building waterproofing. The paint is sprayed on a base layer which is cement, sand and gravel, and the like, and a waterproof coating is formed. The coating has dual effects of waterproofing and corrosion resisting. The paint has the advantages of high bonding strength with the base layer, stable performance, no environmental pollution, and convenient construction. The paint is a novel high-performance waterproof paint.

Description

technical field [0001] The invention belongs to the field of architectural waterproof coatings, in particular to a water-based acrylic waterproof coating and a preparation method thereof. Background technique [0002] The current paint-based waterproof materials mainly include several types: 1. Solvent-based waterproof paint. There are mainly polyurethane waterproof coatings, polyurethane modified bitumen waterproof coatings, SBR modified bitumen waterproof coatings, rubber waterproof coatings, silicone rubber waterproof coatings, etc. Their common feature is that organic solvents are used as carriers, which generally have the advantages of high strength, high elongation, and good impermeability. However, due to the use of organic solvents, the environmental pollution and the impact on the health of production and construction personnel are relatively large. Organic solvents. As a solvent-based coating, it has relatively high requirements on the dryness of the foundation,...
