Problems solved by technology

The melamine veneer can imitate various patterns arbitrarily, the color is bright, and the hardness and wear resistance are excellent after impregnation. However, the proportion of traditional printing paper impregnated with melamine resin is not high because the printing weight must be considered when impregnating. , resulting in a certain gap between the realistic texture and fullness of the veneer and solid wood
Although some technologies have introduced melamine veneer panels produced by melamine modification or simply adding brighteners, market feedback still cannot achieve real high-gloss or high-fidelity effects, and the adhesion of varnish spray paint to melamine veneer panels Poor easy to crack

Embodiment 1

[0017] A production method and process of a high-gloss melamine veneer with a solid wood effect:

[0018] 1. Modified melamine formal resin is prepared by reacting melamine, formaldehyde, diethylene glycol, methyl silicone oil, polyether and silane coupling agent.

[0019] 2. The total gluing amount of the modified melamine formal resin in the printing paper impregnated modified melamine formal resin layer to the printed wood grain paper is controlled at 145%, and the gluing amount controlled by dipping is 55% of the total gluing amount , dipping and second dipping control the amount of gluing to 45% of the total amount of gluing. The dipping speed is controlled at 20 m / min. After the printing paper is impregnated with melamine formal resin and dried in a nine-section oven, it also needs to be cooled by cooling rollers and conveyor belts to obtain a melamine formal resin layer.

[0020] 3. Use particle board and modified melamine formal resin layer for hot pressing, cool to r...

Embodiment 2

[0023] It is characterized in that: a production method and process of a high-gloss melamine veneer panel with a solid wood effect:

[0024] 1. Modified melamine formal resin is prepared by reacting melamine, formaldehyde, diethylene glycol, methyl silicone oil, polyether and silane coupling agent.

[0025] 2. The total gluing amount of the modified melamine formal resin in the printing paper impregnated modified melamine formal resin layer to the printed wood grain paper is controlled at 150%, and the gluing amount controlled by dipping and dipping is 58% of the total gluing amount , dipping and dipping control the amount of gluing to 42% of the total amount of gluing. The dipping speed is controlled at 20 m / min. After the printing paper is impregnated with melamine formal resin and dried in a nine-section oven, it also needs to be cooled by cooling rollers and conveyor belts to obtain a melamine formal resin layer.

Embodiment 3

[0029] A production method and process of a high-gloss melamine veneer with a solid wood effect:

[0030] 1. Modified melamine formal resin is prepared by reacting melamine, formaldehyde, diethylene glycol, methyl silicone oil, polyether and silane coupling agent.

[0031] 2. The total gluing amount of the modified melamine formal resin in the printing paper impregnated modified melamine formal resin layer on the printed wood grain paper is controlled at 155%, and the gluing amount controlled by dipping is 60% of the total gluing amount , the dipping and second dipping control the amount of gluing to 40% of the total amount of gluing. The dipping speed is controlled at 20 m / min. After the printing paper is impregnated with melamine formal resin and dried in a nine-section oven, it also needs to be cooled by cooling rollers and conveyor belts to obtain a melamine formal resin layer.

Abstract

The invention relates to the technical field of machining of decorative plates, in particular to a process for producing a high-gloss melamine veneer with a solid wood effect. According to the process, a part of silane coupling agent is introduced into a modified melamine formaldehyde resin, so that the bonding capability of an inorganic matter such as a resin adhesive and a fibrous layer is improved, the capability of bonding with a finishing varnish also is improved, a lifelike texture effect is achieved, and the problems of weak adhesive force and high cracking rate after the finishing varnish is sprayed onto the melamine veneer also are solved.

Description

technical field [0001] The invention relates to the technical field of decorative board processing, in particular to a production process of a high-gloss melamine decorative board with a solid wood effect. Background technique [0002] At present, melamine veneer is formed by dipping printing papers of different colors and textures into melamine resin glue, and then partially curing it, and then covering it on particleboard and MDF by hot pressing. It can be made into decorative materials such as composite flooring and home panels. . The melamine veneer can imitate various patterns arbitrarily, the color is bright, and the hardness and wear resistance are excellent after impregnation. However, the proportion of traditional printing paper impregnated with melamine resin is not high because the printing weight must be considered when impregnating. , resulting in a certain gap between the realistic texture and fullness of the veneer and solid wood. Although some technologies ...
