Embodiment 1

[0030] The ratio of each component:

[0031] The ratio (by weight) of the raw materials of component A is: 60% acrylic emulsion, 20% water-based polyurethane emulsion, 10% filler, 1% additive, and 9% water;

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

[0033] Preparation method: Add acrylic emulsion and water into the reaction kettle, heat to 65~75°C, then slowly add water-based polyurethane emulsion, and keep the controlled stirring time for 30 minutes, then cool down to room temperature, add additives sodium benzoate, BYK- 33 defoamer, activated calcium carbonate, after stirring evenly, testing, wrapping, and preparing component A. Portland cement and active calcium carbonate are proportioned by weight, accurately weighed, stirred evenly in a mixer, tested, and packaged to prepare component B. During construction, the proportion of components A and B by weight: 1:0.5 should be mixed evenly be...

Embodiment 2

[0035] The ratio (by weight) of the raw materials of component A is: 70% acrylic emulsion, 10% water-based polyurethane emulsion, 10% filler, 3% additive, and 7% water;

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

[0037] Preparation method: Add acrylic emulsion and water into the reaction kettle, heat to 65~75°C, then slowly add water-based polyurethane emulsion, keep the stirring time under control for 30 minutes, then cool down to room temperature, add additives sodium benzoate, defoaming agent, active calcium carbonate, stirred evenly, tested, packaged, and prepared as component A. 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 weight percentage of components A and B: 1:1 is used after mixing evenly, and the waterproof coating after mixing must be used within 6 hours.

Embodiment 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%, additive 1%, water 9%;

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

[0041] Preparation method: Add styrene-acrylic emulsion and water into the reaction kettle, heat to 65~85°C, then slowly add water-based polyurethane emulsion, and keep the controlled stirring time for 30 minutes, then cool down to room temperature, add sodium benzoate and defoamer 1. Active calcium carbonate, stirred evenly, detected, packaged and transferred to prepare component A. 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 weight percentage of components A and B: 1:1.5 is used after mixing evenly, and the waterproof coating after mixing must be used within 6 hours....

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,...
