Environment-friendly paint for construction materials and preparation method of environment-friendly paint for construction materials

Abstract

The invention relates to the technical field of preparation of paint for construction materials and discloses environment-friendly paint for construction materials and a preparation method of the environment-friendly paint for the construction materials. The environment-friendly paint is prepared from, by weight, 20-30 parts of rutile type nano titanium dioxide, 20-25 parts of molecular sieves, 15-25 parts of ferric chloride, 10-15 parts of calcium oxide, 10-15 parts of edible gelatin, 8-15 parts of potassium / zinc salts and 2-5 parts of graphene, and ethanol solution being 60-70% in volume fraction serves as a solvent. The environment-friendly paint is free of harmful components, generation of harmful substances in use of the paint is avoided, and the molecular sieves have an adsorption effect; the rutile type nano titanium dioxide is great in color, suitable for current paint aesthetic demands and less prone to fading or color changing; edible gelatin is high in adhesion and capable of adhering the paint to surfaces of the construction materials without shedding, uniformity in component dispersion can be realized by the aid of the edible gelatin, and accordingly the prepared paint is uniform in material quality and excellent in utilization effect. The preparation method of the paint is free of waste water and waste gas, so that pollution in a production process is avoided.

Description

technical field [0001] The invention relates to the technical field of preparation of building material coatings, in particular to an environment-friendly coating for building materials and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. Coatings generally consist of four basic components: film-forming substances (resins), pigments (including extender pigments), solvents and additives. [0003] According to the main film-forming substances used in coatings, coatings can be divided into oily coatings, fiber coatings, synthetic coatings and inorganic coatings; according to the properties of coatings or paint films, they can be divided into ...

Problems solved by technology

[0005] With the acceleration of the pace of life, people have shorter and shorter requirements for the period from the completion of the building decoration to the occupancy. However, most of the existing building materials and coatings are added with organic solvents such as benzene, which is more harmful to the human body and will also cause certain damage to the environment. Therefore, the research and development of environmentally friendly architectural coatings is increasingly urgent

[0006] In such an environment, a series of environmentally friendly coatings have emerged as the times require, but the existing environmentally friendly coatings basically contain toxic substances such as polyethyleneimine and acrylic resin, which will cause certain damage to human skin and eyes.
