Embodiment 1

[0038] An inorganic aldehyde-removing fire-resistant water-based paint, calculated in parts by weight, includes the following components:

[0039] 68 parts of water-based epoxy modified acrylic resin, 11 parts of inorganic aldehyde-removing modifier, 8 parts of flame retardant, 0.3 part of HY-1608A wetting and dispersing agent, 0.2 part of dodecyl alcohol ester, polydimethylsiloxane 0.1 parts and 21 parts of deionized water.

[0040] The flame retardant is obtained by mixing melamine phosphate, zinc borate and magnesium hydroxide in a mass ratio of 0.3:1:0.3.

[0041] The preparation method of waterborne epoxy modified acrylic resin is:

[0042] Weigh the epoxy resin and mix it into diethylene glycol butyl ether, heat up to 110°C, stir and disperse evenly, then add methyl methacrylate, acrylic acid and styrene in sequence, after mixing evenly, add ammonium persulfate, and stir to react After 3 hours, the temperature was lowered to 75°C, and the reaction was continued for 1.5...

Embodiment 2

[0050] An inorganic aldehyde-removing fire-resistant water-based paint, calculated in parts by weight, includes the following components:

[0051] 62 parts of water-based epoxy modified acrylic resin, 6 parts of inorganic aldehyde-removing modifier, 5 parts of flame retardant, 0.1 part of HY-352 wetting and dispersing agent, 0.1 part of propylene glycol ether, 0.05 part of polyether-siloxane copolymer and 15 parts of deionized water.

[0052] The preparation method of waterborne epoxy modified acrylic resin is:

[0053] Weigh the epoxy resin and mix it into diethylene glycol butyl ether, heat up to 100°C, stir and disperse evenly, then add methyl methacrylate, acrylic acid and styrene in sequence, after mixing evenly, add benzoyl peroxide, After stirring and reacting for 2h, cool down to 65°C and continue to react for 1h to obtain water-based epoxy-modified acrylic resin; the mass ratio of epoxy resin, methyl methacrylate, acrylic acid, styrene and diethylene glycol butyl eth...

Embodiment 3

[0062] An inorganic aldehyde-removing fire-resistant water-based paint, calculated in parts by weight, includes the following components:

[0063] 75 parts of water-based epoxy modified acrylic resin, 18 parts of inorganic aldehyde-removing modifier, 10 parts of flame retardant, 0.5 part of HY-6170 wetting and dispersing agent, 0.3 part of ethylene glycol butyl ether acetate, GPE type polyoxyethylene 0.2 parts of ether and 30 parts of deionized water.

[0064] The preparation method of waterborne epoxy modified acrylic resin is:

[0065] Weigh epoxy resin and mix it into diethylene glycol butyl ether, raise the temperature to 120°C, stir and disperse evenly, then add methyl methacrylate, acrylic acid and styrene in turn, after mixing evenly, add methyl ethyl ketone peroxide, and stir to react After 2 to 5 hours, cool down to 85°C and continue the reaction for 2 hours to obtain a water-based epoxy-modified acrylic resin; the mass ratio of epoxy resin, methyl methacrylate, acry...

Abstract

The invention discloses an inorganic formaldehyde-removing fireproof water-based paint, which is prepared from the following ingredients in parts by weight: 62 to 75 parts of water-based epoxy modified acrylic resin, 6 to 18 parts of inorganic formaldehyde-removing modifiers, 5 to 10 parts of flame retardants, 0.1 to 0.5 part of wetting dispersants, 0.1 to 0.3 part of coalescing agents, 0.05 to 0.2 part of antifoaming agents and 15 to 30 parts of deionized water. The water-based epoxy modified acrylic resin used in the invention is green and environment-friendly, after the flame retardant, the inorganic formaldehyde removal modifier and various auxiliaries are added, the paint not only is environment-friendly, but also has relatively strong flame retardance, weather resistance and adhesive force, in addition, harmful gases such as formaldehyde emitted by other materials can be removed, and therefore, the paint has a good formaldehyde removing effect.

Description

technical field [0001] The invention relates to the field of environmentally friendly coatings, in particular to an inorganic aldehyde-removing fire-resistant water-based coating. Background technique [0002] With the continuous improvement of people's living standards in recent years, interior decoration materials have become more and more abundant, and some materials will gradually release toxic and harmful substances such as formaldehyde during use. Formaldehyde pollutants mainly come from decorative materials such as plywood, joinery boards, paints and coatings used for interior decoration. It is a colorless and soluble irritating gas, which is relatively harmful to the human body. and respiratory tract stimulation, causing nervous system, immune system, and endocrine system dysfunction. It also has embryotoxicity, teratogenicity, and carcinogenicity. Moreover, the existing building decoration materials have poor flame retardant effects, and are prone to fires and prope...
