Description
Technical Field
The invention relates to the technical field of dry powder coatings, in particular to a moisture-proof and mildew-proof dry powder coating.
Background
The dry powder paint is a paint mainly using inorganic materials as main film forming materials and is widely applied to decorative coatings of external walls, internal walls and the like of buildings. However, in the south, the south comes back to south easily in spring, so that a large amount of water drops are adsorbed on the wall surface of a building, the traditional dry powder coating is composed of a small amount of organic matters and a large amount of inorganic fillers, a large amount of water drops are easily adsorbed on the wall surface, bacteria are easily bred and mildewed after the surface of the coating absorbs moisture, the coating can change color after the water drops are adsorbed, the surface of the coating absorbs water differently in the south back, the color is inconsistent, the hardness of the traditional dry powder coating is poor, the coating is easily scratched, and the normal use of the coating is seriously affected.
Disclosure of Invention
The invention aims to provide a dry powder coating with good scratch-resistant, damp-proof and mildew-resistant effects.
In order to solve the technical problems, the technical scheme of the invention is as follows: the moisture-proof and mildew-proof dry powder coating is prepared from the following raw materials in percentage by weight: 28-33% of white cement, 10-18% of white stone powder, 15-17.5% of sepiolite, 8-10% of diatomite, 7-10% of rutile titanium dioxide, 8-10% of calcium oxide, 3-5% of kaolin, 10-13% of redispersible latex powder, 0.05-0.07% of etherified starch, 0.3-0.5% of heterocyclic compound mildew inhibitor, 1.5-1.8% of photocatalyst and 0.85-1% of cellulose.
As a further improvement of the invention, the material consists of the following raw materials in percentage by weight: 30% of white cement, 12% of white stone powder, 15% of sepiolite, 8% of diatomite, 10% of rutile titanium dioxide, 9% of calcium oxide, 3% of kaolin, 10% of redispersible latex powder, 0.05% of etherified starch, 0.4% of heterocyclic compound mildew inhibitor, 1.6% of photocatalyst and 0.95% of cellulose.
The white cement enhances the hardness of the product after construction and drying, and ensures that the paint is not easy to scrape after being dried; the sepiolite and the diatomite have natural materials with larger specific surface area and unique internal pore channel structure in nonmetallic minerals, and have extremely strong adsorption and humidity regulation functions. The rutile titanium dioxide has good physical and chemical stability, has the highest refractive index and strong covering power in white pigment, has good dispersibility in dry powder paint, plays a role in protecting the stability of color, and ensures that the color of the paint does not change obviously after the paint meets water.
As a further improvement of the invention, the heterocyclic compound mildew preventive is 2-alkyl-4-isothiazoline-3-ketone. The heterocyclic compound mildew inhibitor has good thermal stability, no toxicity, no irritation, good sterilization and mildew prevention effects, and can effectively prevent the propagation and growth of mildew on the surface of a dry film.
As a further improvement of the invention, the photocatalyst is nano TiO2White carbon black composite photocatalytic material. Nano TiO 22The white carbon black composite photocatalytic material takes white carbon black as a carrier and nano TiO2The photocatalyst has good adsorption and capture performance and photocatalytic degradation performance on volatile matters such as formaldehyde, can effectively adsorb and decompose harmful substances such as formaldehyde in a room, and has the effect of protecting the environment.
As a further improvement of the invention, the redispersible latex powder is a vinyl acetate-ethylene copolymer. The redispersible latex powder can be redispersed after meeting water, has good flexibility due to high ethylene content, and can improve the bonding strength, bending strength, deformability, wear resistance and construction performance of the mortar.
Compared with the prior art, the invention has the advantages that: the components of the dry powder coating provided by the invention are matched with each other, so that the dry powder coating has excellent mildew resistance and scratch resistance, does not change color when meeting water, has good color stability, can effectively adsorb harmful substances such as indoor formaldehyde and the like, has excellent environmental protection performance, has extremely strong adsorption performance due to the synergistic effect of the sepiolite and the diatomite, ensures the dryness of the surface of the coating without giving uncomfortable feeling because water vapor in the air is adsorbed in pores in the south-bound day and water beads are not adsorbed on the surface of the coating, and has excellent moisture resistance because the water in the pores is evaporated when the temperature rises.
