Exterior paint

Abstract

The invention discloses an eco-texture paint, belonging to the field of building materials. The paint comprises 10 to 20 parts of calcium powder, 20 to 30 parts of 425# portland cement, 20 to 30 parts of redispersible powder, 0.2 to 0.8 parts of hydroxypropyl methyl cellulose, 0.2 to 0.5 organosilane powder, 0.3 to 0.6 parts of wood fibre, 2.0 to 3.0 parts of bentonite, 10 to 20 parts of light calcium carbonate, 5 to 6 parts of titanium dioxide, 0.2 to 0.5 parts of thixotropic lubricant, 0.2 to 0.5 parts of starch ether, and 120-mesh colorful stone powder. The water is used as a disperse medium, and high-molecular polymer and nano-material are organically combined with inorganic mineral materials, so that the service life of the product is increased, and the color is harmonious and natural and never fades. The inorganic cementitious materials in the product has an open micropore structure, and can help to adjust the balance of water vapor content, moisture permeability and automatic balance, so that buildings are enabled to breathe. The calcium powder in the product can hydrolyze and oxidize corrosive saline-alkaline substances having damaging effects in the wall and then separate out while the wall is released into the water vapor, thereby purifying indoor and outdoor air quality.

Description

technical field [0001] The invention relates to an inorganic coating, which belongs to the field of building materials, in particular to an exterior wall coating. Background technique [0002] A large number of external wall latex paints, glazed bricks, and glass curtain walls are used in the exterior wall finishes of modern buildings in my country. These materials are used for exterior wall finishes, which are very closed to the entire building and have no air permeability. In the plastic bags, the indoor air will change from good to poor with the length of living time, and the living indoor environment will not feel comfortable. Especially when glazed tiles are laid on the indoor floor, and latex paint is applied to the walls and roof of the house, the indoor air will feel abnormally dry when the doors and windows are closed in winter, and a humidifier is needed to add moisture to the air. In hot weather in summer, you will feel more humid and hotter, and you must turn on ...

Problems solved by technology

The gelling material of latex paint is an organic gelling material, which is affected by climate freeze-thaw, high temperature, wind, rain, snow, and frost. The durability is poor. Most latex paints will fade, weather and peel in two or three years. , Peeling; Make the buildings that cost a lot of money to decorate beyond recognition, not only affect the beautification of the urban environment, but also increase the cost of repainting for the second and third times
