Further preferably, the aerosol paint suitable for underground parking lot scribing comprises, by weight, 40-50 parts of color paste, 10-20 parts of film forming agent, 3-7 parts of fluorescent pigment, 20-40 parts of diluent and 1-3 parts of plasticizer.
Further preferably, the aerosol paint suitable for underground parking lot scribing comprises, by weight, 45 parts of color paste, 15 parts of film forming agent, 5 parts of fluorescent pigment, 33 parts of diluent and 2 parts of plasticizer.
Further preferably, the fluorescent pigment is at least one of fluorescent yellow, fluorescent green and fluorescent blue.
Further preferably, the fluorescent pigment is fluorescent yellow.
Preferably, the color paste comprises the following raw materials in parts by weight: 10-20 parts of pigment, 50-70 parts of acrylic resin, 0.5-3 parts of wetting dispersant and 10-30 parts of organic solvent.
Further preferably, the color paste comprises the following raw materials in parts by weight: 14 parts of pigment, 64.5 parts of acrylic resin, 1.5 parts of wetting dispersant and 20 parts of organic solvent.
Further preferably, the organic solvent is n-butyl acetate.
Preferably, the film forming agent is at least one selected from alkyd resin, petroleum resin and organic silicon resin.
Further preferably, the film forming agent is a silicone resin.

Preferably, the diluent comprises at least one of ethyl acetate, butyl acetate, xylene, and butyl diethanolate.
Further preferably, the diluent is a mixture of ethyl acetate and butyl acetate, and the mass ratio of the ethyl acetate to the butyl acetate is 15:18.
The volatilization speed of the diluent is too slow, so that the drying time is delayed, meanwhile, the paint film can generate sagging phenomenon, the volatilization speed of the diluent is too fast, the diluent can not be leveled during the film coating, and the diluent can not sufficiently wet the base material, so that the adhesive force of the paint film is affected. The applicant finds that when the diluents are ethyl acetate and butyl acetate, the diluent not only can well dissolve acrylic resin and organic silicon resin, but also provides a reasonable volatilization gradient, and under the action of other components, the sprayed paint film is fine, uniform and free from sagging, flat and glossy, and has certain adhesive force.
Preferably, the plasticizer comprises at least one of dibutyl phthalate, dioctyl phthalate, diisooctyl phthalate, triphenyl phosphate, and tricresyl phosphate.
Further preferably, the plasticizer is dibutyl phthalate.
Preferably, the pigment is permanent yellow and/or fast yellow.
Further preferably, the pigment is permanent yellow.
Preferably, the acrylic resin is a thermoplastic acrylic resin.
Further preferably, the thermoplastic resin is an aqueous acrylic emulsion.
Preferably, the mass ratio between the pigment and the acrylic resin is (1-2): (5-7). The mass ratio of pigment to aqueous acrylic emulsion affects the mechanical properties and the luminous brightness of the paint film. The paint is excessive in pigment consumption, the viscosity of a paint film is increased, construction is difficult, the paint cannot be completely covered by the aqueous acrylic emulsion, the surface of the paint film is more exposed, the water resistance and adhesive force of the paint film are reduced, when the pigment consumption is small, the adhesive force of the follow-up fluorescent pigment is insufficient, the luminous brightness is weakened, the indication effect is reduced, meanwhile, the water resistance and weather resistance of a system are also influenced, and the applicant finds that when the mass ratio of the pigment to the aqueous acrylic emulsion is (1-2): and (5-7), the acrylic ester and the pigment are mutually covered, so that under the combined action of the plasticizer, the water resistance, weather resistance and adhesive force of the paint film are improved, the fluorescence intensity of the paint film is also improved, the indication effect at night is enhanced, and certain safety performance is ensured.
Further preferably, the mass ratio between the pigment and the acrylic resin is 1.4:6.45.
preferably, the wetting dispersant is a polyacrylate polymer.
Further preferably, the wetting dispersant is a modified polyacrylate polymer having an amine value of 20 to 30mgKOH/g.
The wetting dispersant improves the gloss of the paint film and promotes compatibility between the pigment and the resin. The applicant finds that when the wetting dispersant is a modified polyacrylate polymer, the dispersant forms an adsorption layer on the surface of the pigment, so that the charge on the surface of solid particles is increased, the reaction force among particles forming three-dimensional obstruction is improved, and meanwhile, the macromolecular extended chain with larger steric hindrance is tightly connected with the acrylic resin, so that the pigment and the acrylic resin are tightly adhered together, the effects of covering a bottom layer and blocking light are achieved, and the adhesive force and weather resistance of a paint film are improved.
Further preferably, the amine value of the modified polyacrylate polymer is 25mgKOH/g.

The film forming agent is methyl phenyl polysiloxane resin, and is purchased from Hubei Xinhai, and the model is SH-9601. The fluorescent pigment is fluorescent yellow.
The diluent is a mixture of ethyl acetate and butyl acetate, and the mass ratio of the ethyl acetate to the butyl acetate is 15:18.
The plasticizer is dibutyl phthalate.
The color paste comprises the following raw materials in parts by weight: 20 parts of pigment, 70 parts of acrylic resin, 1.5 parts of wetting dispersant and 20 parts of organic solvent.
The pigment was permanent Yellow (c.i Yellow 83), available from clariant under the model PV Fast Yellow HR.
The acrylic resin is aqueous acrylic emulsion, and is purchased from Guangdong tripod, and the model is J2003.
The mass ratio between the permanent yellow H4G and the aqueous acrylic emulsion is 2:7.
the wetting dispersant is a modified polyacrylate polymer, and is purchased from Wacker, germany and has the model number of VOK-PA 4503.
The organic solvent is n-butyl acetate.
The invention also provides a preparation method of the aerosol paint for underground parking lot scribing, which comprises the following preparation steps:
(1) And sequentially adding the pigment, the acrylic resin, the wetting dispersant and the organic solvent into a reaction kettle according to parts by weight, wherein the stirring speed is 800r/min, and the stirring time is 60min, so as to prepare the color paste.
(2) And (3) sequentially adding color paste, a film forming agent, fluorescent pigment, a diluent and a plasticizer into a reaction kettle according to parts by weight at the rotation speed of 1300r/min, and stirring for 20min to prepare a paint semi-finished product.
(3) Filtering the semi-finished paint product by a 400-mesh filter screen, and then using an automatic filling machine according to the gas-liquid ratio of the semi-finished paint product to the dimethyl ether of 1:1 are filled into an aerosol tin can according to the proportion, and the aerosol product is obtained.
Comparative example 1
The mass ratio between the pigment and the acrylic resin is changed to 3:7, changing the mass ratio between the ethyl acetate and the butyl acetate into 1:2, the remainder being the same as in example 1.
Comparative example 2
The procedure of example 1 was followed except that ethyl acetate was not added as a diluent, and the plasticizer was changed to triphenyl phosphate.
Comparative example 3
The wetting dispersant modified polyacrylate polymer is changed into a modified polyurethane solution, which is purchased from Pick chemistry and has the model of BYK-164, and the mass ratio between ethyl acetate and butyl acetate is changed into 1:1 and the rest are the same as in example 1.
