Environment-friendly paint and preparation method thereof

Abstract

The invention discloses environment-friendly paint. The environment-friendly paint is prepared from raw materials in parts by weight as follows: 8-15 parts of waterborne alkyd resin, 15-23 parts of attapulgite clay, 10-20 parts of polyethyleneimine, 12-15 parts of an acrylate emulsion, 10-30 parts of diatom ooze, 3-5 parts of activated carbon, 13-17 parts of negative ion powder, 1.8-2.5 parts of a coalescing agent, 3-6 parts of plant pigments, 2-3 parts of a dispersing agent, 0.5-1.5 parts of a propellant, 0.4-0.7 parts of a defoaming agent and an appropriate amount of deionized water. The environment-friendly paint has the decorative function of common environment-friendly paint, can also be effectively antibacterial, is long in antibacterialpropertylasting time and stable in effect, has the function of adsorbing harmful substances and is energy-saving and environment-friendly.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and in particular relates to an environmentally friendly paint and a preparation method thereof. Background technique

[0002] Paint is a material that can be applied to the surface of an object to be coated and form a firmly adherent continuous film. It can be both inorganic, such as electroplated copper, electroplated nickel, electroplated galvanized, etc. It can also be organic, such as most organic polymer materials, which constitute a major part of the paint market today. Most of the existing paints are added with organic solvents such as benzene, which is harmful to the human body and will also have a certain impact on the environment. As people become more and more aware of environmental protection, this requires a reliable performance that is harmless to the human body and the environment. Contaminated paint.
