Water-based melamine resin wood board
Technical Field
The invention relates to the technical field of veneers, in particular to a water-based melamine resin wood board.
Background
Along with the development of society, the demand of furniture is bigger and bigger, and masses are more and more aesthetic, no matter be new panel furniture, still some not enough pleasing to the eye wood furniture, the panel or the plank structure of its constitution all need carry out the process of skinning, can not only play pleasing to the eye effect, can also play the protective layer, effectively protect inside material, make its durable more.
In the prior art, the leatheroid is generally pasted in a mode that the leatheroid is coated outside a plate or a wood board, a paint spraying process is adopted to spray paint on the surface of the leatheroid in order to ensure the attractiveness of the leatheroid, a large amount of formaldehyde can be generated, and the plasticity can be greatly reduced after the painted leatheroid is solidified.
Disclosure of Invention
In order to solve the problems, the application provides a water-based melamine resin wood board, which mainly solves the problems that when a base plate is processed in the prior art, a solid wood board and a wood veneer need to be subjected to a paint spraying process, a large amount of formaldehyde and odor are generated, plasticity is reduced after the paint spraying process is adopted, and the like
A water-based melamine resin wood board comprises the following steps:
a board pasting process: attaching the water-based melamine resin veneer on a substrate in a direct attaching/re-attaching mode;
the direct sticking process is to hot press a semi-finished board by a steel plate by adding connection melamine impregnated paper and a base plate to a water-based melamine resin veneer;
the re-pasting process is to finish the water-based polycyanate resin veneer by pressing and pasting the wood veneer by a steel plate, and then compound the wood veneer on different base material plates by using different glue to obtain a semi-finished plate.
The water-based melamine resin is melamine formaldehyde resin formed by condensation polymerization of melamine and formaldehyde;
the water-based melamine resin veneer is prepared by adopting the processes of glue preparation → veneer placing → color trimming → first wood veneer surface impregnation → first drying → second wood veneer surface impregnation → second drying → cooling and cutting.
The second impregnating material is prepared by mixing melamine formaldehyde resin and wear-resistant paint.
The veneer is made of natural veneer/technical veneer.
The base plate using direct sticking includes, but is not limited to, a shaving board, a medium density fiberboard, a multi-layer board, a fire-proof board, a finger-joint board, a bamboo-wood fiberboard, a waterproof board, an europa board, a lime board, an aluminum board, a gypsum board, a rubber floor, and a calcium silicate board.
The substrates to be laminated include, but are not limited to, particle board, medium density fiber board, multi-layer board, fire-proof board, finger board, bamboo-wood fiber board, waterproof board, europe pine board, lime board, aluminum board, gypsum board, rubber floor, calcium silicate board.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
1. according to the invention, natural veneer or scientific veneer is processed and sewn, and then water-coated polyurethane resin is coated on the surface of the natural veneer or scientific veneer, so that the scratch-resistant protection effect is achieved; after the aqueous polyurethane resin is coated on the surface of the veneer, the veneer can be coated and curled, and the plasticity is better than that of the veneer.
2. Compared with the normal product used as a paint process, the product has more comprehensive advantages, mainly replaces the fussy property, the fireproof performance and the environmental protection performance of the processed paint, and has higher efficiency.
Detailed Description
The invention discloses a waterborne melamine resin wood board, which can be realized by appropriately improving process parameters by taking the contents of the wood board as reference by the technical personnel in the field. It is expressly intended that all such similar substitutes and modifications which would be obvious to one skilled in the art are deemed to be included in the invention. While the present invention has been described in terms of preferred embodiments, it will be apparent to those skilled in the art that variations and modifications in the methods and applications described herein, as may be made and equivalents used, may be resorted to without departing from the spirit and scope of the invention.
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description of the present invention is provided with reference to specific embodiments.
1. A water-based melamine resin wood board is characterized in that: the method comprises the following steps:
a board pasting process: sticking the water-based melamine resin veneer on a substrate in a direct sticking/re-sticking manner;
the direct sticking process is to hot press a semi-finished board by a steel plate by adding connection melamine impregnated paper and a base plate to a water-based melamine resin veneer;
the re-pasting process is to finish the water-based melamine resin veneer by pressing a steel plate, and then compound the semi-finished board on different base material boards by using different glue.
The water-based melamine resin is melamine formaldehyde resin formed by condensation polymerization of melamine and formaldehyde;
the water-based melamine resin veneer is prepared by adopting the processes of glue preparation → veneer placing → color trimming → first wood veneer surface impregnation → first drying → second wood veneer surface impregnation → second drying → cooling and cutting.
The second impregnating material is prepared by mixing melamine formaldehyde resin and wear-resistant paint.
The veneer is made of natural veneer/technical veneer.
The base plate using the direct sticking includes, but is not limited to, a shaving board, a medium density fiber board, a multi-layer board, a fire-proof board, a finger-joint board, a bamboo-wood fiber board, a waterproof board, an Ouchong board, a lime board, an aluminum board, a gypsum board, a rubber floor, and a calcium silicate board.
The substrates to which the repositionable adhesive is applied include, but are not limited to, chipboard, medium density fiberboard, multi-layer board, fire protection board, finger board, bamboo fiberboard, water-proof board, europa board, lime board, aluminum board, gypsum board, rubber flooring, calcium silicate board.
In conclusion: the coating is processed and sewn through natural veneer or scientific veneer according to the requirement of surface plasticity, and then the water-coated polyurethane resin is coated on the surface of the coating, so that the scratch-resistant protection effect is achieved; after the aqueous polyurethane resin is coated on the surface of the veneer, the veneer can be coated and curled, and the plasticity is better than that of the veneer.
It should be noted that: the color of the medium repair is as follows: when the color difference of the wood veneer is large, the color needs to be added, and when the color difference is not large, the color is not added.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
