Problems solved by technology

[0003] However, when acrylic paint is used as an interior wall paint, it is often not beautiful enough. Manufacturers generally only pay attention to the anti-peeling performance of the paint when preparing the paint, so there are few decorative acrylic paints on the market.

Embodiment 1

[0011] Example 1: A method for preparing an acrylic fluorescent paint. Add protective glue to 52 parts of deionized water, stir and raise the temperature, add 0.4 parts of potassium persulfate at 50 ° C, add 12 parts of methyl methacrylate, acrylic acid 22 parts of butyl ester, 1.5 parts of acrylic acid, 9 parts of vinyltriethoxysilane, 4 parts of emulsifier, 0.2 parts of ferric sulfate solution with a mass fraction of 30%, control the reaction temperature at 60°C, and continue to add organosilane 40 parts of joint agent, 18 parts of fluorescent pigment emulsion, and 4 parts of talc powder with a fineness of 700 meshes were heated to 80°C for 1 hour, and the pH value was adjusted to 7.8 to prepare fluorescent paint.

Embodiment 2

[0012] Example 2: A method for preparing an acrylic fluorescent paint. Add protective glue to 50 parts of deionized water, stir and raise the temperature, add 0.3 parts of potassium persulfate at 50 ° C, add 10 parts of methyl methacrylate, acrylic acid 20 parts of butyl ester, 1 part of acrylic acid, 8 parts of vinyltriethoxysilane, 3 parts of emulsifier, 0.1 part of ferric sulfate solution with a mass fraction of 30%, control the reaction temperature at 60°C, and continue to add organosilane 35 parts of joint agent, 15 parts of fluorescent pigment emulsion, and 3 parts of talcum powder with a fineness of 600 meshes were heated to 80°C for 1 hour, and the pH value was adjusted to 7.5 to prepare fluorescent paint.

Embodiment 3

[0013] Example 3: A method for preparing an acrylic fluorescent paint. Add protective glue to 55 parts of deionized water, stir and raise the temperature, add 0.5 parts of potassium persulfate at 50 ° C, add 15 parts of methyl methacrylate, acrylic acid after 5 minutes 25 parts of butyl ester, 2 parts of acrylic acid, 10 parts of vinyltriethoxysilane, 5 parts of emulsifier, 0.4 part of ferric sulfate solution with a mass fraction of 30%, control the reaction temperature at 60°C, and continue to add organosilane 45 parts of joint agent, 20 parts of fluorescent pigment emulsion, 5 parts of talc powder with a fineness of 800 mesh, after heating up to 80°C for 1 hour, adjust the pH value to 8.0 to make fluorescent paint.

Abstract

The invention discloses a preparation method of an acrylic fluorescent coating. The fluorescent coating is prepared by adding a protective glue into 50-55 parts of deionized water, performing stirring and heating, adding 0.3-0.5 part of potassium peroxydisulfate at 50 DEG C, adding 10-15 parts of methyl methacrylate, 20-25 parts of butyl acrylate, 1-2 parts of acrylic acid, 8-10 parts of triethoxyvinylsilane, 3-5 parts of emulsifier and 0.1-0.4 part of ferric sulfate solution with the mass fraction of 30% after 5 min, controlling the reaction temperature at 60 DEG C, then adding 35-45 parts of organosilicon, 15-20 parts of fluorescent pigment emulsion and 3-5 parts of talcum powder and raising temperature to 80 DEG C, and conducting reacting for 1 h. The fluorescent coating of the invention has a gradually stronger fluorescence sense in the preparation process, and the appearance of the coating film is dense and delicate. The fluorescent coating has not only artistic appearance but also alkali resistance and has no foaming, peeling or powder falling, so as to avoid loss of gloss and discoloration. The discoloration degree is less than grade 2 and the preparation process is simple. The acrylic fluorescent coating can be widely applied to architectural decoration, advertising boards, road marking, etc.

Description

technical field [0001] The invention relates to a preparation method of paint, in particular to a preparation method of acrylic paint. Background technique [0002] Coatings that use polyacrylate as a film-forming aggregate are called acrylic coatings. This type of coating has the advantages of light color, color retention, gloss retention, weather resistance, corrosion resistance and pollution resistance, and has been widely used in automobiles, aircrafts, machinery, electronics, furniture, construction, leather finishing, papermaking, printing and dyeing, wood processing, industrial For the finishing of plastics and daily necessities, in recent years, acrylic paints at home and abroad have developed rapidly, and currently account for more than 1 / 3 of the paint consumption. [0003] However, when acrylic paint is used as an interior wall paint, it is often not attractive enough. Manufacturers generally only pay attention to the anti-peeling performance of the paint when pr...
