Embodiment 1～2
[0094] The raw material components of the environment-friendly porcelain-like paint provided in this example are as shown in Example Nos. 1-2 in Table 1.
[0095] Its spraying method comprises the following steps:
[0096] 1) Apply a water-based PP primer on the preform as a whole, dry the primer and apply a middle-layer water-based ceramic coating on its surface, and coat the surface with a solvent-free surface layer after drying the middle-layer water-based ceramic coating. UV coating;
[0097] The drying conditions are: heat curing at 60-80°C for 15-25 minutes or natural drying for more than 24 hours;
[0098] 2), drying the solvent-free UV coating on the surface layer;
[0099] The drying conditions are as follows: after heating and leveling the surface layer of UV coating at 50-65°C for 3-7 minutes, then the preform of the coated surface layer of solvent-free UV coating enters the light source area at a speed of 4-6m / min , curing time 6~10s, cumulative radiation 400~90...
Embodiment 3～5
[0101] The raw material components of the environment-friendly porcelain-like paint provided in this example are as shown in Example numbers 3-5 in Table 1.
[0102] Use a small blade to clean the burrs of the injection-molded PP material flower pots, and then use a cleaning agent to clean the oil stains on the surface of the flower pots. Then spray PP primer with a film thickness of 5-10u, bake at 60-70°C for 20-25 minutes, and proceed to the next process after cooling;
[0103] Intermediate coat one or more layers of intermediate water-based ceramic paint, spray it evenly on the PP primer in the form of mist, and then scatter it on the freshly sprayed base color in the form of dots, let it naturally Produce the effect of flowing glaze, dry naturally for more than 24 hours;
[0104] It is best to spray a surface layer of solvent-free UV paint on it, heat and level the surface layer of solvent-free UV paint at 50-65°C for 3-7 minutes, and then apply the surface layer of solve...

Abstract
The invention relates to the field of artware and building decoration, in particular to an environment-friendly ceramic simulating coating. The coating comprises a water-based PP primer, a middle layer water-based ceramic simulating paint and a surface layer non-solvent type UV painting. The water-based PP primer is prepared from 40-70 parts of water-based modified chlorinated polypropylene resin, 5-25 parts of deionized water, 3-15 parts of calcium powder and 1.0-13 parts of auxiliaries. The middle layer water-based ceramic simulating paint is prepared from 40-70 parts of modified acrylic emulsion, 5-30 parts of ceramic powder, 10-25 parts of water, 5-25 parts of color paste and 1-10 parts of auxiliaries. The surface layer non-solvent type UV paint is prepared from 30-80 parts of photosensitive resin, 10-50 parts of activated monomer, 2-8 parts of a photoinitiator and 0.1-1.5 parts of auxiliaries. According to the environment-friendly ceramic simulating coating, benzene emission is eradicated, the VOC content in the coating is lowered, and the painting still has the good physical property. The invention further relates to a spraying method of the environment-friendly ceramic simulating coating.
Description
technical field [0001] The invention relates to the field of handicrafts and building decoration, in particular to an environment-friendly imitation porcelain paint and a spraying method thereof. Background technique [0002] Coating is a broad concept. Including water-based, oil-based. Oily ones include various one-component and two-component room temperature curing paints, high temperature baking paints, UV light curing paints, etc., as well as PU coatings, powder electrostatic coatings, etc. Coating is a material that can be applied to the surface of objects by different construction methods to form a solid film with strong adhesion, certain strength and continuity. Because most of the early paints used vegetable oil as the main raw material, they are also called paints. The main components of coatings include film-forming substances, additives, pigments, and solvents. Its main functions are three-fold: protection, decoration, and concealing product defects to enhance ...
