Embodiment 1～3

[0112] The porcelain-like paint provided in this embodiment has the raw material components as shown in the embodiment numbers 1-3 in Table 1.

[0113] Its spraying method comprises the following steps:

[0114] 1), on the preform, coat the PP primer as a whole, coat the middle layer water-based ceramic coating on its surface after the primer is dried, and coat the surface layer UV coating on its surface after the described middle layer water-based ceramic coating is dried;

[0115] The drying conditions are: heat curing at 60-80°C for 15-25 minutes or natural drying for more than 24 hours;

[0116] 2), drying the surface layer UV coating;

[0117] The drying conditions are as follows: after heating and leveling the applied surface layer UV coating at 55-65°C for 3-7 minutes, then the preform of the applied surface layer UV coating enters the light source area at a speed of 4-6m / min, and the curing time 6~10s, cumulative radiation 400~900mj / cm 2 .

Embodiment 4～7

[0119] The porcelain-like paint provided in this embodiment has the raw material components as shown in the embodiment numbers 4-7 in Table 1.

[0120] 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;

[0121] Medium-layer water-based ceramic coating, spray it evenly on the PP primer in the form of mist, and then scatter it in the form of dots on the ground color just sprayed, so that it will naturally produce the effect of flowing glaze , dry naturally for more than 24 hours;

[0122] It is better to spray another UV topcoat on it, and after heating and leveling the coated UV coating at 55-65°C for 3-7 minutes, then spray the preform of the coated UV coating at a temperature of 4-6m / min. The speed enters the light sou...

Embodiment 8～11

[0124] The porcelain-like paint provided in this embodiment has the raw material components as shown in the embodiment numbers 8-11 in Table 1.

[0125] 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 manually paint the 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;

[0126] Medium-layer water-based ceramic coating, spray it evenly on the PP primer in the form of mist, and then scatter it in the form of dots on the ground color just sprayed, so that it will naturally produce the effect of flowing glaze , dry naturally at 15±5°C for 30-36 hours in winter;

[0127] It is better to spray another UV topcoat on it, and the thickness of the paint film is 18±2μm. After heating and leveling the UV coating on the surface layer at 55-65°C for 5 minutes, the preform of the UV coat...

Abstract

The invention relates to the fields of handicrafts and architectural decoration, and concretely relates to a porcelain imitation coating. The porcelain imitation coating comprises a PP primer, a middle layer aqueous porcelain imitation coating and a top layer UV coating; the PP primer comprises 45-75 parts of chlorinated polypropylene modified acrylic resin, 5-20 parts of a diluent, 10-35 parts of a pigment filler and 1-10 parts of an assistant; the middle layer aqueous porcelain imitation coating comprises 40-70 parts of a modified acrylic emulsion, 5-30 parts of ceramic powder, 10-25 parts of water, 5-25 parts of a color paste and 1-10 parts of an assistant; and the top layer UV coating comprises 30-80 parts of photosensitive resin, 3-25 parts of an active monomer, 1.5-5 parts of a photoinitiator, 5-40 parts of the diluent and 0.1-5 parts of an assistant. The coating primer difficulty cracks and strips, the middle layer coating has strong weather ability, ageing resistance and strong interlayer adhesion, and the top layer coating is environmentally friendly and has short air-drying solidification time. The invention also relates to a spraying method of the porcelain imitation coating. The method is easy to operate.

Description

technical field [0001] The invention relates to the field of handicrafts and building decoration, in particular to a porcelain-like 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 the value of the product. ...
