It was coated with a solid content of m2 . These precoated papers are usually laminated onto plywood particle board, medium density fiberboard, etc. using a laminator using vinyl acetate emulsion, acrylic emulsion, or an adhesive mixed with these emulsions and urea resin. In some cases, it is made as a decorative board. (hereinafter referred to as the wet lamination method) In recent years, this lamination process has been changed to a method in which the back side of precoated paper is coated with a heat-sensitive adhesive resin in advance, and this is replaced with a laminator and the base material is simply passed through a hot roll or hot press machine. So-called pre-glued pre-coated paper to which pre-coated paper a can be pasted has gradually become popular. The features of this pre-coated paper with back glue are that the lamination process is completely dry, making process control easy, low pollution, and mechanically, there is no need to use expensive laminating equipment, making it more efficient than the conventional wet lamination method. Not only does it have many advantages during production, but when it is made into a decorative board, there is no moisture involved during lamination, so there is less expansion and contraction of the paper, so the surface finish is extremely good compared to the wet lamination method. It is.

使用した場合には、致命的な欠点となる。 These products are extremely easy to use because they use thermoplastic resin, so you can set the time between lamination after lamination as desired, but since they use thermoplastic resin, the surface has sufficient scratch resistance (scratch strength). There is a drawback that it does not show up. This lack of scratchability is a fatal drawback when laminate base materials are used as furniture or interior decoration materials.

くなつてしまうのである。 In addition, when using a thermosetting resin, sufficient scratch resistance can be obtained, which is a drawback when using a thermoplastic resin.
If the time from Uranori resin coating to lamination is not limited to a certain period, the adhesive will harden and become unusable. Generally speaking, it is said that diallyl phthalate resin must be used within 6 months, and melamine resin must be used within 3 months before it becomes unusable. In the case of pre-coated paper using these thermosetting resins as the backing, the curing conditions when laminating the base material require considerable heat pressure and time, resulting in extremely poor productivity. be. Naturally, it is possible to adjust the conditions such as heat pressure and time during lamination by increasing the amount of curing agent added to the resin or adding additives. Not only is there a limit, but the time required from applying the adhesive to laminating the substrate is further limited, which narrows the range of usage conditions.
