Description

A kind of environmental protection paint and preparation method thereof

technical field

The invention specifically relates to an environmentally friendly paint and a preparation method thereof.

Background technique

Paint English name: paint or coating. Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating.” Coatings are generally composed of film-forming substances, fillers (pigments and fillers), solvents, and additives. According to performance requirements, sometimes the composition will change slightly, such as varnish without pigments and fillers, and powder coating without solvent.

Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. Paint is viscous oily pigment, flammable when wet, insoluble in water, slightly soluble in fat, soluble in alcohol, aldehyde, ether, benzene, alkanes, easily soluble in gasoline, kerosene, diesel. There are many types of paints on the market, but they mainly contain toluene and a small amount of benzene, which have a great impact on the human body. At present, paints are all chemicals, especially after painting, they will continuously volatilize organic compounds (VOC) and free bodies (TDI). Not only will it produce ozone pollution to nature, but it will also cause headaches, general paralysis, anemia, cancer and other diseases in the human body, which poses a serious threat to human health, but it is an unavoidable necessary material.

Therefore, the industry urgently needs to provide a kind of environmental sanitation, use safe paint.
