Problems solved by technology

However, due to the interface effect between the adhesive and the board, the binding force between the decorative film and the plywood is low, and the decorative board is prone to bulging after a certain period of time or after being damp, causing the decorative film to separate from the plywood, which affects the film-faced wood-based panels. Normal use

Embodiment 1

[0029] A kind of preparation method of film veneer wood-based panel, comprises the following steps:

[0030] (A): Wetting the decorative film with a sodium carbonate solution with a mass fraction of 5%, after wetting for 10 minutes, cleaning and drying to obtain a pretreatment film;

[0031] (B): The adhesive polyurethane was scraped onto the surface of the pretreatment film with a thickness of 10 μm, and heated at 40°C for 3 minutes to obtain an adhesive film;

[0032] (C): The surface of the plywood is sprayed with a silane coupling agent solution with a mass fraction of 0.5%. The silane coupling agent solution is prepared by dissolving methoxysilane in methanol. After the surface of the plywood is dried, a pretreated plywood is obtained;

[0033] (D) The adhesive film was preheated at 60°C for 200s and then pasted to the surface of the pretreated plywood to obtain an adhesive film-faced wood-based panel.

Abstract

The invention provides a preparation method of an adhesive film veneer artificial board. The preparation method of the adhesive film veneer artificial board comprises the following steps that firstly, a decorative film is pretreated to obtain a pretreated film, an adhesive is blade-coated on the surface of the pretreated film, and an adhesive film is obtained by heating; and then a plywood is pretreated, the pretreated plywood is obtained, the adhesive film is heated and attached to the surface of the pretreated plywood, and the adhesive film veneer artificial board is obtained. According to the preparation method of a veneer artificial board adhesive film, a decorative film and the plywood are pretreated, and meanwhile, the binding force of the adhesive film and the plywood is increased by 0.1-0.3 MPa through the coating technology of preheating and pressurizing; in addition, the adhesive is coated on the decorative film in a blade coating manner, so that the utilization rate of the adhesive can be increased by 40-60%.

Description

technical field [0001] The invention relates to the technical field of veneered wood-based panels, in particular to a method for preparing an adhesive film veneered wood-based panel. Background technique [0002] Facing wood-based panels are widely used in furniture, cabinets and fixed wardrobes, floors, wooden doors and other decoration fields, and are important raw materials for the custom wooden furniture industry. At present, the wood-based panel facing materials on the market mainly include various impregnated film papers and polymer film non-paper-based facing materials. Among them, PVC polymer decorative film is very popular among consumers because of its realistic texture and delicate touch, which can meet the individual needs of different consumers for furniture. [0003] The preparation method of the present facing wood-based panel is mainly to spray the adhesive on the plywood, then stick the PVC decorative film with pattern on the plywood, after the adhesive dri...
