High-efficiency environment-friendly antibacterial mildew-proof paint containing nano film-forming agent and preparation method thereof

Abstract

The invention provides a high-efficiency environment-friendly antibacterial mildew-proof paint containing a nano film-forming agent and a preparation method thereof. The paint is prepared from the following raw materials: heavy calcium powder, ash calcium powder, white Portland cement, hollow microspheres, nano silicon dioxide, rutile titanium dioxide, dicalcium silicate, sepiolite powder, sodiumoxalate, talcum powder, tourmaline powder, attapulgite clay, sodium bentonite, polyvinyl alcohol powder, redispersible latex powder, lithium sulfate, calcium lignosulphonate, hydroxypropyl methyl cellulose, wood fibers and an organic silicon polyether composite defoaming agent. The prepared interior and exterior wall dry powder paint is suitable for interior and exterior walls, is non-toxic and environment-friendly, does not pollute the environment, does not influence body health, has excellent antibacterial and anti-mildew construction performance and other properties, is long in service life, is a dry powder coating, is simple in production process, and has the advantages of being convenient to transport, long in storage period and the like.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and relates to a high-efficiency, environment-friendly, antibacterial, mildew-proof, nano film-forming agent-containing coating and a preparation method thereof. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, people's awareness of energy saving and environmental protection has been continuously enhanced. Especially, the energy consumption of buildings involves a wide range of areas and consumes a lot of energy. All of them are oil-based paints or solvent-based paints, but these paints have many disadvantages, such as difficult transportation and storage, complicated production and preparation process, high cost, easy aging when used for exterior wall coatings, single heat insulation method, and high cost. The effect is not good, and the strength and weather resistance are not good. It is easy to freeze and crack in winter. The...

[0002] With the increasingly serious energy crisis and environmental pollution, people's awareness of energy saving and environmental protection has been continuously enhanced. Especially, the energy consumption of buildings involves a wide range of areas and consumes a lot of energy. All of them are oil-based paints or solvent-based paints, but these paints have many disadvantages, such as difficult transportation and storage, complicated production and preparation process, high cost, easy aging when used for exterior wall coatings, single heat insulation method, and high cost. The effect is not good, and the strength and weather resistance are not good. It is easy to freeze and crack in winter. The adhesion between the paint and the cement base is low and the smoothness is poor. It needs to be putty or primer on the cement wall base, which is easy to crack, foam and powder. , can not be directly sprayed on the cement concrete base, the soluble glue used in the paint will increase the emission of VOC, pollute the air environment, if used in the interior wall, it will bring serious harm to human health
