Problems solved by technology

The main raw materials of existing interior wall coatings are chemical raw materials, which contain a small amount of formaldehyde and alcohol ether organic solvents, which have poor stability and poor water resistance, and surface pollutants can easily cause shrinkage cavities in the coating film.

Embodiment Construction

[0011] The inventive method implements according to the following steps:

[0012] (1) Grind old soil and alum into fine particles with a pulverizer.

[0013] (2) Mix white cement and lime paste and put them into the mixer, then put the crushed old soil and alum in a certain proportion, and then add rubber tree sap and stir evenly.

[0014] (3) The mixed dry solid after stirring and discharging is then prepared into a thick liquid product through the step of adding water.

[0015] The present invention is constructed according to the following methods:

[0016] After cleaning the inner wall, sprinkle water on the wall 5 days in advance when the temperature is 2-10°C; sprinkle water on the wall 3 days in advance when the temperature is 10-25°C; sprinkle water on the wall 1 day in advance when the temperature is above 25°C. In the first pass, use cement mixed mortar to make a primer (the mud content is not more than 5%), then mix a certain proportion of water with the pro...

Abstract

Natural building interior paint is made by mixing raw materials including, by weight, 50-130 parts of white cement, 250-400 parts of lime putty, 4.2-6.9 parts of alums, 10-20 parts of original soil, 0.1-0.8 part of rubber tree sap and 60-90 parts of water. The preparation steps include: crushing the original soil and the alums; adding the white cement and the lime putty into an agitator after mixing, sequentially adding the crushed original soil and the alums into the agitator, adding the rubber tree sap, well mixing, and adding water into the dry mixed solid after mixing and discharging to obtain the finished natural building interior paint. The natural building interior paint has fine technical performance and low cost, the raw materials are natural, nontoxic and harmless, resources can be saved while environment is protected, and the natural building interior paint is widely applicable to painting engineering for interior walls of various buildings.

Description

technical field [0001] The invention relates to the technical field of finishing engineering of building interior walls, in particular to a building interior wall paint prepared from natural materials. Background technique [0002] Architectural coatings used for interior wall decoration of buildings or structures are called interior wall coatings. Interior wall paint has some characteristic requirements different from exterior wall paint: First, interior wall paint is directly painted on the inner surface of buildings or structures, and is more closely related to people's life or work. In this sense, the decorative effects of interior wall coatings (such as the feel, smoothness and texture of the coating film, etc.) will receive more attention; second, interior wall coatings will have a greater impact on the indoor environment, and should be It has proper air permeability and hygroscopicity, and a completely airtight and non-hygroscopic coating film will cause condensation...
