Abstract

The invention discloses a manufacturing method for a pure natural decorative coating of interior and exterior walls of buildings. The method comprises the following steps: weighting the following raw materials by weight percent: 5-10% of glutinous rice flour, 40-55% of red clay, 5-10% of husk, 15-20% of lime and 20-30% of water; crushing the glutinous rice flour and gelatinizing under high temperature, thereby acquiring glutinous rice slurry; grinding the lime to 325 meshes or above, thereby acquiring lime powder; grinding the red clay to red clay powder at 250-350 meshes or above; cooking and disinfecting the husk under high temperature, thereby acquiring disinfected husk; dispersing and stirring the glutinous rice slurry, lime powder, red clay powder, disinfected husk and water and packaging, thereby acquiring the coating. According to the invention, the coating is prepared from various natural raw materials, so that the coating is nontoxic and harmless, can be used for decorating the interior and exterior walls of buildings, has the characteristics of simplicity in operation, high adhesive property, quick drying, waterproof and damp-proof effect, non-scaling and non-falling effect, no toxicity, no harm, no pollution and natural color and can achieve the heat-insulating, heat-preserving and soundproof functions when the coating is used for decorating the interior and exterior walls of buildings.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing a pure natural interior and exterior wall decorative paint. Background technique [0002] Decorative coatings are used to paint the surface of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. Water resistance is also required, and self-cleaning properties are required. The paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. Its function is to decorate and protect the outer wall of the building, so that the appearance of the building is beautiful and tidy, so as to achieve the purpose of beautifying the urban environment and giving people a refreshing space. At the same time, it can also protect the building wall and prolong its service life. Wall decoration coatings can be roughly divided into exterior wall coatings and inter...
