The present invention relates to a method for producing a reinforced paper coated board, which makes it possible to obtain a reinforced paper coated board with significantly improved strength between the paper sheets. As for the paper pasted painted board by the conventional method,
Two types of paper are known: colored coated paper laminated onto a substrate such as lauan plywood, and uncolored white paper laminated onto a substrate and the outer surface of which is coated with colored paint such as enamel paint. In all of these conventional paper-covered painted boards, the synthetic resin has not penetrated into the inside of the paper, so the inter-paper strength is extremely weak. Since the cellophane tape is peeled off, there is a risk that the outer coating may peel off from between the sheets of paper when the cellophane tape is peeled off. On the other hand, the invention of this application applies a vinyl chloride resin liquid onto the surface of a substrate such as lauan plywood or a thin synthetic resin board, and after semi-drying, thin paper is pasted as a pasting paper and the outer surface is dried. After that, a mixed resin solution of melamine resin, urea resin, and alkyd resin is applied to this, and after semi-drying, amino alkyd enamel is applied as a top coat and dried to form a synthetic resin between the sheets and the outside, and a top coat on the surface. The paper is bonded together and cured, and the reinforced transparent synthetic resin liquid is infiltrated between the paper sheets to create a reinforced paper.
It is attached to the substrate surface of a synthetic resin board or the like with an adhesive, and an enamel-based topcoat layer is applied to the outer surface of the sticker, which is integrated with the reinforcing transparent synthetic resin that has penetrated into the outer surface of the sticker and between the sheets. According to the present invention, it is possible to obtain a reinforced paper-covered painted board that has been bonded and adhesively cured, and therefore, a reinforced paper-covered board that has significantly improved the strength between the paperboards can be obtained. It is extremely useful because reinforced paper coated boards can be produced reliably and easily. Therefore, in the invention of this application, a transparent synthetic resin sealer for the purpose of reinforcing the paper gap is applied to the outer surface of the sticker in advance, and a top coat such as enamel paint is applied while the synthetic resin is not hardened. This is then dried to form a solid, solid coating including the paper gaps. As a sealer that penetrates between papers and hardens,
The choice must be made depending on the adhesion of the enamel paint applied to the outer surface, but in general, synthetic resins of the same type are suitable. For example, if the top coat is unthane enamel, a moisture-curing one-component polyurethane sealer is recommended as the interpaper reinforcing agent. Further, when the top coating is an amino alkyd enamel, melamine or urea alkyd resin is suitable as the interpaper reinforcing agent. In addition, in the case of resins of the same type, one with a lower molecular weight has better permeability. In the manufacturing method of the invention of this application, the normally used vinyl acetic acid emulsion adhesive alone is sufficient, and there is no need to mix urea resin, etc., so there is no risk of gelation of the adhesive, and workability is improved. is extremely good. Furthermore, since the paper is coated with a sealer, the enamel paint applied to the outer surface does not penetrate into the paper, giving it a good texture. The following table shows the test results when comparing the interpaper strength of the manufacturing method according to the present invention with that of the conventional coating method. However, in order to compare the interpaper strength, no slip agent was added to the top coat.
