Melamine faced boards, whose base material is particle board and MDF, are made by bonding the base material and the surface. There are mainly two types of surface veneers, domestic and imported. Because they are treated with fire prevention, abrasion resistance, and waterproof soaking, the use effect is like that of composite wood flooring.
Melamine faced boards, referred to as melamine boards, the full name is melamine impregnated film paper veneer wood-based panels. It is to soak paper with different colors or textures in melamine resin adhesive, and then dry to a certain degree of curing. It is paved on the surface of particleboard, moisture-proof board, medium density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard, and the decorative board is formed by hot pressing. In the production process, it is generally composed of several layers of paper, and the number depends on the application.
Soak the decorative paper in a melamine solution, and then press it on with a hot press. Therefore, the moisture-proof board for furniture is generally called melamine moisture-proof board. Melamine formaldehyde resin is a solution with extremely low formaldehyde content, which is environmentally friendly, so that it will not cause secondary pollution, but will reduce the release of the substrate inside. This treatment method has been recognized by everyone.
- Composition
The name of the specification for melamine-faced boards is melamine-impregnated film paper-faced wood-based panels, saying that the melamine-faced boards are a part of its facing composition. Generally, it is composed of surface paper, decorative paper, covering paper and bottom paper.
(1) Surface paper is placed on the top layer of the decorative board to protect the decorative paper, making the surface of the board highly transparent after heating and pressing, and the surface of the board is hard and wear-resistant. This kind of paper requires good water absorption performance, white and clean, and transparent after dipping.
- Decorative paper, that is, wood grain paper, is an important part of the decorative board, with or without background color. The decorative paper printed into various patterns is placed under the surface paper and mainly plays a decorative role. This layer requires paper with good hiding power, impregnation, and printing properties.
(3) Covering paper, also called titanium white paper, is generally placed under the decorative paper when making light-colored decorative boards to prevent the underlying phenolic resin from penetrating the surface. Its main function is to cover the color spots on the surface of the substrate. Therefore, good coverage is required. The above three kinds of paper are impregnated with melamine resin respectively.
- Bottom paper is the base material of the decorative board, which plays a role in the mechanical properties of the board. It is made by soaking in phenolic resin glue and drying. During production, several layers can be determined according to the application or the thickness of the decorative board. When choosing this kind of panel furniture, in addition to satisfactory color and texture, you can also distinguish the appearance quality from several aspects. Whether there are stains, scratches, indentations, pores, whether the color and luster are uniform, whether there are bubbles, whether there are local paper tears or defects.
- Performance of melamine decorative board
- It can imitate various patterns arbitrarily, with bright color, and can be used as veneer of various wood-based panels and woods. It has high hardness, wear resistance and good heat resistance.
- The performance of chemical resistance is general, and it can resist the abrasion of general acid, alkali, grease and alcohol and other solvents.
(3) The surface is smooth and clean, easy to maintain and clean. Melamine board has excellent properties that natural wood cannot have at the same time, so it is often used in interior construction and decoration of various furniture and cabinets.
- Advantages and disadvantages
The advantage of this kind of board is that the surface is smooth, not easy to deform because the expansion coefficient of both sides of the board is the same, the color is bright, the surface is more wear-resistant, corrosion-resistant, and the price is economical.
The disadvantage of this kind of board is that the edge banding is easy to collapse, and it can only be straight banded if it can’t be cracked.
