Problems solved by technology

[0004] The Chinese patent document with the application number 201310738713.3 discloses a formaldehyde-removing nano-mixture and its preparation method. The nano-mixture is mainly composed of photocatalyst-composite titanium dioxide, superabsorbent graphene, nano-anion tourmaline, and biological polyphenols. It can absorb a certain amount of formaldehyde and PM2.5 particles, but the preparation process of the nano-mixture is complicated and cannot release negative ions

preparation example Construction

[0044] Correspondingly, the present invention also provides a preparation method of an environmentally friendly water-based paint, comprising the following steps: step a) mixing 0.5 to 5 parts by weight of a defoamer, 1 to 20 parts by weight of a thickener, 1 to 10 parts by weight of a dispersant and Put 0-200 parts by weight of water into the mixer, add 50-150 parts by weight of composite anion powder and 40-100 parts by weight of anion additive after the dispersion is complete, and stir evenly. The speed of the mixer is 600-2500 rpm. It is composed of crystal salt, nano-silica, nano-phosphate titanium dioxide and nano-zinc dioxide; step b) reduce the speed of the mixer to 400-800 rpm, mix 700-900 parts by weight of water-based resin dispersion, 10-100 parts by weight The film-forming aid, 0.5-5 parts by weight of the defoamer and 0.1-1 part by weight of the pH regulator are put into the mixer, and stirred for 30-50 minutes to obtain an environmentally friendly water-based pai...

Abstract

The invention provides environment-friendly water-based paint and a preparation method thereof. The environment-friendly water-based paint comprises water-based resin dispersion, water, compound anion powder, an anion additive, a coalescing agent, a deforming agent, a thickening agent, a dispersing agent and a pH regulator. Crystal salt can undergo water loss after absorbing water molecules from air and the process is carried out alternately to continuously generate anions, so that the redundant cations in the air can be effectively neutralized, the floating dust and particles in the air are adsorbed and the air is purified. Nano silicon dioxide, nano phosphate titanium dioxide and nano zinc dioxide are used as photocatalyst materials which can be used for effectively degrading the harmful gases such as formaldehyde in the air under illumination so as to generate superoxide anion free radicals and accompany negative oxygen ions. Under the combined action of the crystal salt and the photocatalyst, the prepared environment-friendly water-based paint has the advantages of forming high-concentration negative oxygen ion environment which can be kept and sufficiently absorbing the harmful gases and particles such as dust so as to effectively improve the indoor air quality.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly water-based paint and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the living environment are getting higher and higher, and more attention is paid to the impact of the environment on human health. Furniture is an essential item in the living environment, which is closely related to the living environment of modern people, and paint is an indispensable material in furniture production. At present, there are many functional coatings on the market, such as coatings with functions such as heat preservation, heat insulation, flame retardancy, and sound insulation, but they cannot really improve the impact of the coating itself on the human body. [0003] Negative ions are the protectors of the environment. Negative ion air is called "longevity element" or "air vitamin"...
