TW438669B - Method for producing composite board - Google Patents

Abstract

The present invention relates to a method for producing a composite board, comprising transporting a wood board to be soaked into a resin tank with fire retardant additive through a transport device, after the board being thoroughly soaked with the resin, compressing the board by a plastic roller and drying the resin to form a protective film, pasting paper already printed to the surface (pasting by glue), or thermal transfer printing a pattern and forming a layer of wear-resistant plastic material on the surface by roll pressing or spray coating, laminating the back of the board with EVA foam material, hot rolling pattern on the foam material, and cutting into a specified shape.

Description

V. Description of the Invention (1) [Technical Field] The present invention relates to a method for manufacturing a split-type plate material, especially a wood plate material and a foam formed by combining each other, and the plate obtained by a special process treatment. With moisture-proof, fire-proof and antibacterial effects, the printing materials are easy to adhere to it, and the surface layer is not easy to wear and peel. When it is installed, it can absorb unevenness in the ground, and has a soft protective effect, which improves the overall aesthetics and improves the use effect. [Previous technology] At present, the general split floor in the market is divided into plastic floor, EVA foam floor and solid wood floor, etc. The thickness of the plastic floor sheet is thin. If the original floor is uneven, the The floor surface is also uneven. The EVA foamed split floor is made of EVA foam, and those who transfer the pattern on its surface, then cut the corresponding grooves and tabs. It is fast to assemble, soft and safe. It is necessary to add a release agent when the foam is released, but the release agent will remain on the foam, which will cause the foam to be difficult to be colored, transferred, etc., or even if the surface has a pattern layer printed on it. After a long period of use, the pattern layer is easy to fall off and form a mottled pattern. Not only the pattern is worn, the foam is also worn, but also it is soft, that is, heavy objects are placed on it for a long time, which can easily cause depression (such as table legs). Partially sunken), quite unsightly. The solid wood floor is poor in moisture resistance and fear of insects, and it needs to be elevated and pre-designed to prevent moisture and insects. Its time-consuming and labor-intensive laying and the solid wood floor are easily deformed due to different climatic humidity. The solid wood flooring has a considerable thickness to prevent deformation. [Purpose and effect]

V. Description of the invention (2) The main purpose of the present invention is to solve the above problems and provide a method for manufacturing a floor board with moderate softness and hardness, wear resistance, fire resistance, moisture resistance and safety. [Technical content] The present invention provides a method for manufacturing a split sheet, which includes the following steps: Step (1): dipping the sheet into a resin tank; it conveys a certain dryness of a wooden board sheet (such as a plywood or a polymer sheet) through a The device is transported and dipped into a resin tank with a moisture-proof effect. After the resin fully penetrates the inside of the board, it is squeezed by a rubber roller, and then a dry film is formed to form a protective film. Step (2) ... Surface beautification treatment; it is a thermal transfer printing on the surface of the board

The above and other objects and advantages of this creation can be easily understood from the detailed description and drawings of the selected embodiment below. Of course, this creation may be different in some other parts or arrangements of other parts, but the selected embodiment is described in detail in this specification and its structure is shown in the drawings. [W of the embodiment] Please refer to the fourth figure. The one shown in the figure is an example of the manufacturing method used in the present invention. This is for illustration only. It is not limited by this method in patent applications. The invention relates to a method for manufacturing a split-type plate and board, which includes the following steps: Step (1) 1: Dipping a board 10 into a resin 12 tank; passing a certain dryness of a board 10 (such as a plywood or a polymer board) through A conveying device 11 conveys and impregnates a resin 12 with a moisture-proof effect. A flame retardant, an antibacterial agent, and an insect repellent can be added to the resin 12 to increase its flame resistance, antibacterial, and insect resistance. Resin 12 fully penetrates the inside of the board, and then extruded by roller 1 3 (the roller 13 is preferably a soft material such as rubber) to remove excess resin 1 2 on the surface of the board 10 to make it adhere to the surface. Uniform; after drying treatment 1 4, a protective film is formed to prevent the wood board 10 from being deformed due to different weather, and the board 10 is moisture-proof, fire-proof,

5. Description of the invention (5) It can absorb uneven ground and has anti-slip effect. Step (five) 5: Cut into a certain shape (see Figures 3 and 4); the board 10 can be provided with a backing adhesive 5 1 on the back of the foam 4 0 before cutting to facilitate placement. % In another embodiment of the present invention, refer to FIG. 5. In step (4), PU liquid can be coated on the back surface of the board 10 and foamed into E foam 4 3 at the same time. The 4 4 pattern is rolled on the back of the foam 4 3. Please refer to the sixth and seventh figures, which is a further embodiment of step (five) 5 1, in which the peripheral edge of the plate 60 cut into a certain shape is provided with corresponding tooth blocks 6 1 to facilitate the group laying. The manufacturing method of the split-type plate and board of the present invention has the following superior effects: () The wood board (such as plywood or polymer board) fully penetrates into the board through resin, which can increase its flame resistance, insect resistance and moisture resistance. A resin protective film is formed on the surface, which is more consistent with the chemical characteristics of the transfer layer or rubber. Compared with the transfer layer or rubber and wood or foam, it makes the ink or glue that is not easy to adhere to it. The material can be attached to it, and it is easy to make a delicate pattern on the surface. (2) The surface of the wood board is coated with a layer of treatment agent by rolling or spray coating. The surface treatment agent contains resin and pu acrylic prepolymer (Ployurethane A c rVy late) is the main component, and contains 5-60% by weight of reactive diluent (Monome rr), 1-15% by weight of light initiator (

Photoinitiator), 1-15% by weight. It is composed of additives (Photosyne rgi st s) and 10% by weight or less of solvent (S ο 1 vent). The glue is rapidly hardened by ultraviolet or light beam irradiation, and its wear index is small. (Abrasion index = weight loss of abrasion / number of revolutions * 1 000 rpm, UV surface treatment agent 500g / l 00 revolution abrasion index), the better the abrasion resistance, the less likely it is to wear. (3). The surface of the board is ground, EV A foam is set on the back, the soft and hard are moderate, and the back of the foam is patterned. When laying, if the floor is uneven, the foam is directly absorbed by extrusion. The surface wood board is not affected, improving the overall aesthetics and improving the use effect.
