Embodiment 1

[0070] The coating process of the bright paint of embodiment 1 may further comprise the steps:

[0071] Step 1. Sanding the base material. The substrate is sanded to form a panel.

[0072] In step 1, the base material is medium density fiberboard with melamine warm white matte paper pressed on the surface. Substrate density 0.75g / cm 3 .

[0073] In step 1, a three-axis sanding device is used to sand the base material. The sand belts on the three-axis sanding equipment are 240 mesh, 320 mesh and 400 mesh in turn.

[0074] Step 2, the first primer treatment. Step 2 includes three processes.

[0075] (1) The process of roller coating primer. Roller coat the first primer on the surface of the panel. The coating amount of the first primer is 15g / m 2 .

[0076] (2) Primer leveling process. Level the panels. Leveling time 100s. The leveling temperature is 50°C.

[0077] (3), drying and curing process. The first primer is irradiated with a first set of ultraviolet lamps...

Embodiment 2

[0100] The coating process of the bright paint of embodiment 2 comprises the following steps:

[0101] Step 1. Sanding the base material. The substrate is sanded to form a panel.

[0102] In step 1, the base material is medium density fiberboard with melamine warm white matte paper pressed on the surface. Substrate density 0.79g / cm 3 .

[0103] In step 1, a three-axis sanding device is used to sand the base material. The sand belts on the three-axis sanding equipment are 240 mesh, 320 mesh and 400 mesh in turn.

[0104] Step 2, the first primer treatment. Step 2 includes three processes.

[0105] (1) The process of roller coating primer. Roller coat the first primer on the surface of the panel. The coating amount of the first primer is 20g / m 2 .

[0106] (2) Primer leveling process. Level the panels. Leveling time 200s. The leveling temperature is 60°C.

[0107] (3), drying and curing process. The first primer is irradiated with a first set of ultraviolet lamps....

Abstract

The invention relates to a coating process of bright paint. The coating process is characterized by comprising the following steps: step 1, sanding a base material; step 2, primary primer treatment; the step 2 comprises three processes; a primer roller coating process; a primer leveling process; the plate is leveled; a drying and curing process; 3, edge coating and drying treatment; the step 3 sequentially comprises a first primer process, a plurality of groups of second primer processes and a plurality of groups of primer sanding processes; a first primer coating process; a second primer coating process; a primer sanding process; step 4, sanding and polishing treatment; the step 4 comprises two processes; a surface sanding process; a polishing and soot blowing process; 5, finish paint spraying treatment is carried out; and step 6, finish paint drying treatment. The problems that in an existing scheme, repeated polishing operation is conducted after paint spraying, the paint spraying efficiency is reduced, and the paint spraying cost is increased are solved.

Description

technical field [0001] The invention relates to the field of coating, in particular to a coating process of bright paint. Background technique [0002] At present, the paint spraying process is mainly based on the spraying primer and topcoat process, and dry sanding, water grinding and polishing operations are still required for bright paint products to meet the use requirements. The improved process uses the method of flow coating UV primer to replace the traditional spraying primer, but the flow coating UV primer still increases the production cost of the enterprise and has high requirements on the process, and the surface of the paint film is prone to blistering, resulting in Ineffective, so the flow coating process still has problems such as high cost and easy bubbling of the paint film, which requires repeated polishing operations after painting, which reduces the painting efficiency and increases the painting cost. How to solve this problem becomes crucial. Contents...
