Problems solved by technology

[0004] However, the paints currently used to decorate the interior and exterior walls of buildings contain harmful substances such as toluene and formaldehyde to varying degrees, and the plasticizers contained in them seriously exceed the standard. These harmful substances will not only pollute the environment, but also endanger people's health. During the decoration process, other decorative wood itself will also emit harmful substances during the processing process. Therefore, we need to design an environmentally friendly water-based paint, which itself has the function of absorbing and purifying toxic gases

Abstract

The invention discloses an environment-friendly water-based paint with adsorption and purification functions. The water-based paint is prepared from the following raw materials in parts by weight: 500-600 parts of deionized water, 80-120 parts of a modified bamboo activated carbon powder, 100-200 parts of polyurethane resin, 50-80 parts of glycerol epoxy resin and 20-30 parts of a defoaming agent.The invention also discloses a preparation method of the water-based paint, which comprising the following steps: (1) preparation of the modified bamboo activated carbon powder; (2) preparation of amix liquor: according to the proportions of the raw materials, putting the polyurethane resin, glycerol epoxy resin, a defoaming agent and deionized water into a reaction vessel for mixing, controlling the temperature at 70 DEG C, and after uniform stirring, carrying out ultrasonic dispersion to obtain a mixed solution A; and (3) mixing. According to the preparation method provided by the invention, the modified bamboo activated carbon powder is used as a raw material, toxic gases such as formaldehyde, toluene and the like contained in air can be effectively adsorbed, bamboo has the characteristics of short growth period, reproducibility and the like, and the raw materials are cheap and easily available, so that the production cost is low, and the water-based paint is a novel environment-friendly water-based paint.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to an environment-friendly water-based paint with adsorption and purification functions and a preparation method thereof. Background technique [0002] Water-based coatings are coatings that use water as a solvent or as a dispersion medium. Water-based coatings include water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. Water-soluble paint is a paint with water-soluble resin as a film-forming substance; water-diluted paint is a solvent-based resin dissolved in an organic solvent, and then with the help of an emulsifier, the resin is dispersed in water to form an emulsion by strong mechanical stirring, which is called In order to post-emulsify the emulsion, the prepared coating can be diluted with water during construction; water-dispersed coating mainly refers to the coating prepared with synthetic resin emulsion as the film-forming substance...
