Embodiment 1

[0039] This embodiment provides a method for making a veneer open paint board, comprising the following steps:

[0040] (1) Use high-density fiberboard base material, fill the uneven surface of the base material with transparent putty ash roll coating, use 320# paper abrasive belt to smooth the surface, remove dust, and stick natural veneer on one side by hot pressing; hot pressing The temperature of pasting was 110° C., and the pressure was 150 kPa. The veneer is thin oak planks. After the veneer is veneered, the cracked and uneven parts of the veneer surface are filled with transparent putty or colored putty, and then the surface of the board with natural veneer is polished and sanded with 320# and 400# automatic sanding equipment;

[0041] (2) Polish the surface of the veneer with a paper abrasive belt to remove dust;

[0042] (3) Do coloring treatment on the veneer, roll coat UV transparent primer, and control the coating amount of transparent primer at 28g / m 2 .

Embodiment 3

[0059] This embodiment provides a method for making a veneer open paint board, comprising the following steps:

[0060] (1) Use high-density fiberboard or plywood base material, fill the uneven surface of the base material with transparent putty ash, polish the surface with 320# paper abrasive belt, remove dust, and paste natural veneer with double-sided hot pressing; The temperature for pressing and pasting is 120°C and the pressure is 120kPa. The veneer is a thin elm board. After the veneer is veneered, the cracked and uneven parts of the veneer surface are filled with transparent putty or colored putty. Use 320#, 400# automatic sanding equipment for sanding;

[0061] (2) Polish the surface of the veneer with a paper abrasive belt to remove dust;

[0062](3) Do coloring treatment on the veneer, roll coat UV transparent primer, and control the coating amount of transparent primer at 30g / m 2 .

[0063] (4) After ultraviolet baking, polish it with 400# paper abrasive belt an...

Abstract

The invention discloses a manufacturing method of a veneer open paint sheet material, and belongs to the technical field of the preparation of paint sheet materials. The manufacturing method of the veneer open paint sheet material comprises the following steps of adopting a high-density fiberboard or plywood base material, filling unlevel places on the surfaces of the base material by using transparent putty in a roller coating manner, grinding the surfaces to be level by using a 320# abrasive paper belt, removing dust, and adhering natural veneers to double surfaces in a hot pressing manner; grinding the surfaces of the veneers to be level by using the abrasive paper belt, and removing dust; carrying out tinting processing on the veneers, and coating UV (Ultraviolet) transparent primer on the veneers in the roller coating manner; after veneers are subjected to ultraviolet baking, grinding the veneers to be level by using a 400# abrasive paper belt, and removing dust; coating gloss oil for color modulation on the veneers in the roller coating manner; grinding the veneers to be level by using the 400# abrasive paper belt, removing dust, and coating a varnish top-coat on the veneers; subjecting the veneers to the ultraviolet baking. According to the manufacturing method of the veneer open paint sheet material, the UV transparent primer is coated on the veneers in the roller coating manner, and the veneers are good in adhesive force; paint films are natural, and are good in plumpness and real in texture; the manufacturing method of the veneer open paint sheet material can be used for completely replacing a conventional manual banking varnish spray coating process, and can be used for generally realizing the production and the manufacturing in an automatic batch mode of a coating process.

Description

technical field [0001] The invention relates to the technical field of varnish board preparation, in particular to a method for making a veneer open paint board. Background technique [0002] Open lacquer is a kind of wood coating process relative to closed lacquer, and it is a process popular in European high-end furniture in recent years. Open paint is a finishing process that completely reveals the tube holes on the wood surface. It is characterized by obvious wood holes, clear texture, small amount of paint coating, matte, strong natural texture, and can be repaired again. [0003] To make open paint on the veneer, the traditional process is to first make a PU sealing primer on the veneer, after polishing, use PU colored Grace to manually wipe one side, do 1~2 transparent primers, wait until completely After drying, sand and then apply PU topcoat. This process involves a long time, high energy consumption, serious volatilization of organic solvents, great pollution to ...
