The present invention relates to a method for processing a curved surface of a post-form decorative board. In detail, when bonding the decorative board and the base material that will be the adherend, the gap created between the curved decorative board and the base material is filled with a low viscosity, high solids content epoxy resin, urethane resin, or vinyl. Our objective is to provide highly reliable decorative board curved products using a method of pouring and filling ester resin, etc. and bonding. Curved surfaces are an advanced use of decorative laminates such as high-pressure melamine decorative laminates, diallyl phthalate decorative laminates, and unsaturated polyester decorative laminates, which are made by impregnating paper, fibers, etc. with thermosetting resin and pressing them.
It is used as a decorative surface material for counters, handrails, sinks, vanities, doors, mantelpieces, etc. In order to process this decorative surface material into a curved surface and bond it to the base material, a highly accurate curved base material (R
This required advanced technology and processing costs to process the base material. Furthermore, even if the decorative board and the base material were bonded together, they did not fit perfectly and a gap was created, and if something hit the surface of the gap, the decorative board would crack and lose its commercial value. The purpose of the present invention is to omit the creation of a curved surface processing part base material (R material) that requires advanced technology and precision, and another purpose is to improve reliability by completely filling and bonding the decorative board and base material. The objective is to obtain a decorative board curved product with high quality. The feature of the present invention is that the gap corner 8 has a narrow portion that is created when the straight base material and the curved decorative board come into contact, which is created between the back surface of the bent part inside the decorative board and the corner of the base material. As in the vanity sink deck shown in Figure 2, voids such as the void corners 9 that do not have openings are created after a single decorative board is three-dimensionally deep-drawn and bonded in the vertical, horizontal, and vertical directions. Resin injection holes 2 and 3 are provided in the base material leading to the corners 8 and 9, and by injecting and exhausting the gap filling adhesive resin through the resin injection holes, the back surface of the curved surface processed portion of the decorative board is This makes it easier to fill and bond the gap corner 8 with the injected resin, which has a narrow portion that occurs between the corner portion of the gap and the corner of the base material, and also makes it possible to fill and bond the gap corner 9, which does not have an opening, with the injected resin. That's what I did. In addition, the volumetric shrinkage caused by the penetration of the resin injected into the void into the base material, the loss of volatilization, and the change from liquid to solid concentrates in the resin injection hole provided in the base material, causing filling and adhesion. This should not occur between the back surface of the curved surface processed part of the decorative board and the corner of the base material. The reason for this is that when resin is injected, the resin injection hole is positioned above the gap to be filled and bonded so that the resin flows from top to bottom, and the resin liquid level is in contact with air, causing the volume of the injected resin to shrink. occurs only within the resin injection hole. Therefore, a post-form decorative laminate product is obtained in which the back surface of the curved surface processed portion of the decorative laminate and the base material are completely filled and bonded with the injected resin. Note that the size and number of resin injection holes provided in the base material leading to the gap corner are determined by the size and shape of the gap corner, injection device, method, etc. Provide two or more
It is suitable to use one as a resin injection hole and the other as an exhaust hole. In addition, the injection hole may be provided in the assembled base material or member before adhesion of the decorative board or after adhesion, but the former is more suitable in terms of workability. Next, the present invention will be explained with reference to a diagram of a bathroom vanity deck as an embodiment. FIG. 1 shows a perspective view of the completed assembly base material. FIG. 2 shows a sectional view taken along line A-A' of only the assembly base material. FIG. 3 shows a sectional view taken along the line A-A' after the decorative boards have been bonded together. A washstand deck base material (core material) 1 is created by assembling members made of wood or the like, and resin injection holes 2 and 3 are formed in the parts where the curved surface processing parts 6, 7, and 7' of the decorative board 5 are to be pasted. Set up each. Next, the decorative board 5 which has been curved in advance or the decorative board 5 which has been curved at the same time as being pasted onto the base material is pasted onto the base material 1 with an adhesive. Next, resin is injected through the injection holes 2 and 3 by natural dripping or by using pressure from an airless gun, etc., to form a gap 6 between the decorative board 5 and the base material 1.
77' is filled and bonded to obtain the desired highly reliable decorative board curved product. Here, the base material refers to the adherend of the decorative board, such as wood, synthetic wood (synthetic resin foam), ceramic products, and metal products, which is called a core material. As mentioned above, a decorative board is a surface decorative material that is press-molded by impregnating printed paper, fibers, veneer, etc. with thermosetting resin, and is pre-curved (post-formed) before being bonded to the base material.
It refers to a product that is bonded to a base material and processed into a curved surface at the same time. Injection resins include epoxy resins, urethane resins, vinyl ester resins, and other room-temperature curing resins with low viscosity and high solids content, but among these resins, volume shrinkage during curing is low, and the adhesiveness and physical properties of the cured product are low. Epoxy resins with excellent properties are most suitable, and may include modified products such as inorganic fillers and plasticizers, but the viscosity of the compound may vary depending on the temperature at the time of injection.
It is best to keep the flow under 100 poise. The injection method is to position the injection port above the gap to be filled and bonded so that the resin flows from top to bottom, and then drop it naturally through the injection hole provided in the base material or apply pressure, or reduce the pressure from the other hole. While injecting. At this time, the resin liquid level is in contact with air at the injection port. After injecting, leave the resin until it hardens, and then begin the next work such as cutting. Therefore, according to the present invention, it is possible to omit the preparation of the base material for the curved surface processing part, which required a high level of skill and precision as in conventional products, leading to cost reduction, and the curved surface processing part of the obtained post-form decorative board is Since the base material and decorative board are completely filled and bonded,
A highly reliable decorative board curved product that does not crack even when hit by objects can be obtained. Next, the present invention will be explained by examples. Example 1 A deck base material (core material) for a vanity washbasin was created by bonding lauan members as shown in Figure 1, and the curved surface was replaced with a curved surface processed member (R material) in the conventional method. For the purpose of injecting filler adhesive into the processing area, diameter 15
Injection holes 2 and 3 of m/m were made using a drill. Next, as a decorative material, a post-form melamine decorative board with a curved surface processed in advance was bonded to the surface of the base material using a rubber adhesive. Next, the epoxy filling adhesive shown in Table 1 is injected by gravity through the injection holes 2 and 3 on the opposite side where the decorative materials were pasted together, and the gap 6 between the curved decorative material and the base material is filled. 7,7′
The parts were filled and glued. Two days after injection, the unnecessary parts at both ends were cut off using a cutter, but the curved parts were completely filled with resin and bonded, resulting in a highly reliable vanity washbasin deck.
