Embodiment 1

[0039] Example 1: see Figure 1 ~ Figure 2 , The three-dimensional paint process for furniture silk screen internal carving provided in this embodiment includes the following steps:

[0040] (1) Soil-filling: After the surface of furniture product 1 to be processed is thickened with a large-scale fixed-thickness sanding machine, a layer of putty is applied to the outer surface of the furniture product 1 and then polished with coarse sandpaper to obtain a base layer 2 ;

[0041] (2) Spraying and polishing the nano-sealing primer: evenly sweep the nano-primer on the surface of the product 1. After the nano-primer is air-dried for 42 to 52 hours, polish and sand with coarse sandpaper to obtain the sealing primer layer 3. ;

[0042] (3) Spraying PE primer: spray the PE primer evenly on the sealing primer layer 3 in two to four times. After the PE primer is air-dried for 30 to 40 hours, sand and sand the surface with sandpaper to obtain the upper primer Lacquer layer 4;

[0043] (4) Thr...

Embodiment 2

[0061] Embodiment 2: The basic steps of this embodiment are the same as those of embodiment 1, except that the preparation method of the PU topcoat further includes the following steps:

[0062] (51) In a four-necked flask equipped with a stirrer, a thermometer, a condenser and a dropping funnel, measure each component in the following molar ratio, toluene diisocyanate 2: polyether glycol 3:1, 4-butane Diol 3: 2,2-Dimethylolpropionic acid 3: Epoxy resin 4: Hydroxypropyl acrylate 2: Triethylamine 1: Nano glass beads 3: Pearl powder 1.5, the toluene diisocyanate and polyether two The alcohol is added to the reaction system, the catalyst dibutyl tin dilaurate is dropped, the reaction is first at 40°C for 30 minutes, then the temperature is raised to 80°C, and the reaction is held at a constant temperature for 1.5 hours;

[0063] (52) Cool down to 70°C, weigh 1,4-butanediol according to step (51), slowly add small molecule chain extender 1,4-butanediol with a dropping funnel, and react...

Embodiment 3

[0069] Embodiment 3: The basic steps of this embodiment are the same as those of embodiment 1, except that the preparation method of the PU topcoat further includes the following steps:

[0070] (51) In a four-necked flask equipped with a stirrer, a thermometer, a condenser and a dropping funnel, measure the components in the following molar ratio, toluene diisocyanate 10: polyether glycol 6:1, 4-butane Diol 4: 2,2-Dimethylolpropionic acid 4: Epoxy resin 3: Hydroxypropyl acrylate 3: Triethylamine 1.5: Nano glass beads 4: Pearl powder 2. Combine toluene diisocyanate with polyether two The alcohol is added to the reaction system, the catalyst dibutyltin dilaurate is dropped, the reaction is first at 40°C for 30 minutes, then the temperature is raised to 80°C, and the reaction is constant for 1.5h-2h;

[0071] (52) Cool down to 75°C, weigh 1,4-butanediol according to step (51), slowly add small molecule chain extender 1,4-butanediol with a dropping funnel, and react at this temperatur...

Abstract

The invention discloses a furniture screen printing internal engraving 3D (three-dimensional) paint process, which is characterized in that a technical flow process comprises the following steps that (1) puttying is carried out, and a substrate layer is obtained; (2) a nanometer sealing primer is sprayed, the grinding is carried out, and a sealing primer layer is obtained; (3) PE (polyethylene) primer is sprayed, and an upper primer layer is obtained; (4) 3D image preparation and decomposition is carried out, which means that 3D images to be subjected to screen printing are prepared and are decomposed into a plurality of transverse plane pattern layers and a plurality of longitudinal cloud point 3D pattern layers; (5) the multilayer screen printing and the finish paint spraying are carried out, and a plurality of compound finish paint layers with pattern layers are obtained; (6) the laser internal engraving is carried out, and longitudinally and transversely nested 3D images are formed. The process has the advantages that through the multilayer screen printing and the internal engraving, the 3D images with 3D effect are formed on products, and vivid and visual effects are realized. The invention also discloses epoxy modified waterborne polyurethane, which has the characteristics of high bonding capability, high modulus and intensity, high temperature resistance and good heat stability, and is suitable for the laser internal engraving.

Description

Technical field [0001] The invention relates to the technical field of furniture manufacturing processes, in particular to a three-dimensional paint process for furniture silk screen internal carving. Background technique [0002] At present, there are many kinds of paint processes for furniture, but the basic functions are to better protect furniture materials and obtain certain decorative effects. [0003] In the traditional paint process, the screen printing process has been widely used in the furniture production process, but all use flat patterns as the content. With the development of furniture paint technology, it is increasingly required to improve product grade and individuality, ensure product quality, reduce costs, and achieve better economic benefits. [0004] For some large furniture, such as wardrobes, closets, decorative cabinets, etc., have a large area of ​​flat surface. The traditional painting process is to make some wood grain or other flat patterns, or use stick...
