Problems solved by technology

But what generally use on the market at present is non-fading traditional oil-based spray paint, such as the spray paint with thermoplastic acrylic resin as the main film-forming substance, which can only be used in wood, plastics and metals; Although the solvent-based ceramic spray paint of the main film-forming substance is water-based spray paint, a large amount of organic solvents are used in the production of this spray paint, which causes certain harm to the environment and human body during production and use.
Moreover, all spray paints on the existing market cannot be automatically eliminated or artificially eliminated quickly, so developing a new type of environmentally friendly and fadeable water-based spray paint has important practical value

Embodiment 1

[0021] Embodiment 1: preparation of white spray paint

[0022] Put 20 parts of water-based acrylic resin HD1093 and 1.2 parts of water-based wetting and dispersing agent into the reactor, and disperse evenly at 600r / min, then add 15 parts of nerolidol, and disperse at 1200r / min for 20 minutes at a high speed; 12 parts of water-based resin, 50 parts of solvent (by mass ratio: 50 parts of ethanol, 20 parts of n-butanol, 27 parts of deionized water, 3 parts of propylene glycol methyl ether) and 0.6 parts of water-based drier SC- 1. Continue to stir for 20 minutes to prepare water-based spray paint. Put the spray paint and DME in a weight ratio of 1.2:1 into an aerosol can equipped with a valve and a press head to obtain a water-based spray paint.

Embodiment 2

[0023] Embodiment 2: preparation of red spray paint

[0024] 30 parts of water-based alkyd resin HK1045-65, 0.5 parts of water-based wetting and dispersing agent, 1.2 parts of bisphenol A and 15 parts of red material 3,3-bis(N-octyl-2-methylindole) phthalate A lactone was put into the reaction kettle, dispersed evenly at 600r / min, then 10 parts of nerolidol was added, and dispersed at a high speed of 1200r / min for 20min; 10 parts of water-based resin, 46 Parts of solvent (according to mass ratio: 50 parts of ethanol, 20 parts of isobutanol, 27 parts of deionized water, 3 parts of propylene glycol methyl ether), 0.8 parts of water-based drier JUST-2500, and continue to stir for 20 minutes to prepare a water-based spray paint. Put the spray paint and DME in a weight ratio of 1.2:1 into an aerosol can equipped with a valve and a press head to obtain a water-based spray paint.

Embodiment 3

[0025] Embodiment 3: preparation of black spray paint

[0026] 36 parts of water-based alkyd resin BCW981, 0.8 parts of water-based wetting and dispersing agent, 4 parts of gluconic acid and 10 parts of black material 3-(N-ethyl-isoamylamino)-6-methyl-7-anilinofluoran Put it into the reactor, disperse evenly under the rotating speed of 600r / min, then add 15 parts of nerolithin, and disperse at a high speed for 20min under the rotating speed of 1200r / min; drop 14 parts of water-based resins and 48 parts of solvent in the formula under the rotating speed of 700r / min ( According to the mass ratio: 50 parts of ethanol, 20 parts of sec-butanol, 27 parts of deionized water, 3 parts of propylene glycol methyl ether), 0.6 parts of water-based drier SC-1, and continue to stir for 20 minutes to prepare a water-based spray paint. The spray paint and DME are potted into an aerosol can equipped with a valve and a press head at a weight ratio of 1.2:1 to obtain a water-based spray paint.

Abstract

The invention provides a color fadeable water-based spray paint, whose components include water-based resin, colorant, color developer, solvent, water-based wetting and dispersing agent and water-based drier; the color developer is bisphenol A, lemon At least one of acid, phosphoric acid, tartaric acid, malic acid, fumaric acid, ascorbic acid and gluconic acid; the color material is white material, red material, blue material, green material, yellow material, orange material, black material of at least one colorant. Its preparation: Take 3 / 4 of the water-based resin according to the mass ratio, take the wetting and dispersing agent, the color developer and the colorant and put them into the reaction kettle, then add nerolidol, and disperse at a high speed for 15-25 minutes; then put in the remaining water-based resin, Solvent, water-based drier, stir well to make water-based spray paint. The prepared water-based spray paint and propellant are potted into an aerosol can equipped with a valve and a press head, and then it can be used. It can be used for temporary painting, wall graffiti, wood or glass spraying, body decoration, graffiti of banners and slogans, map marking, etc.

Description

technical field [0001] The invention relates to spray paint, in particular to a color-fading water-based spray paint for temporary use without long-term retention of colored paintings, wall graffiti, wood or glass spraying, car body decoration, banner slogan graffiti, map marks, etc. [0002] technical background [0003] At present, spray paint has been applied to all aspects of life, and the demand for spray paint in various fields is also increasing year by year and tends to be diversified. The requirements for spray paint are not limited to simple spraying, but more convenient and fast in use and post-processing. But what generally use on the market at present is non-fading traditional oil-based spray paint, such as the spray paint with thermoplastic acrylic resin as the main film-forming substance, which can only be used in wood, plastics and metals; Although the solvent-based ceramic spray paint as the main film-forming substance is water-based spray paint, a large amou...
