Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of a paper-pasted painted board with the purpose of significantly improving the strength between the sheets and obtaining a nine-paper pasted painted board. A sticker strengthened by infiltrating the paper between the sheets is pasted with adhesive on the surface of a substrate such as lauan plywood or synthetic resin board, and an enamel-based top coat layer is applied to the outer surface of the sticker. It is characterized by being integrally bonded and adhesively cured with a reinforcing transparent synthetic resin that has penetrated into the outer surface and between the paper, or a reinforcing transparent synthetic resin liquid is applied to the substrate surface of lauan plywood, synthetic resin thin board, etc. The sticker is strengthened by applying it to the paper surface and between the sheets, and pasting it with a vinyl chloride resin liquid, and when the reinforcing transparent synthetic resin liquid is semi-dry, an enamel-based top coat is applied to the outside surface.□
Section 1. Let it dry and use it to strengthen the space between the sheets and the outer surface of the sticker.1.
1. - ・," 1. Synthesis - Combining the fat liquid and the top coating on the outer surface.
If, Il:f, Bl:e□□i. Aachi 7, ya. As an embodiment, on the surface of a substrate such as lauan plywood or synthetic resin thin plate,
After applying a vinyl chloride resin solution and letting it semi-dry, paste a piece of tissue paper as a pasting paper and transfer the outer surface of the □. After semi-drying, apply it as an aminoalkyd enamel t/top coat and dry to combine and harden the interpaper and outer synthetic resin and the top coat υ paint on the surface, or A mixed resin solution of melamine resin, urea resin, and alkyd resin is applied and permeated onto thin paper as a sticker, and after semi-drying, amino alkyd enamel is applied, dried, rolled up, and this is deposited on the substrate as appropriate. It is something that exists.

Conventional 9 paper-covered painted boards were +I+ colored.

Coated paper pasted onto a substrate such as 2-one plywood,
11. It is known that uncolored blank paper is laminated onto a substrate and the outer surface is coated with colored paint such as enamel paint.

□: In all of these conventional paper-covered painted boards, □ the inner t-t' synthetic resin of the paper is not penetrated, so the inter-paper strength is extremely weak, and after painting, the surface Apply cellophane tape and remove the cellophane tape after a few days.
Because of this, when removing the cellophane tape,
There is a risk that the outer coating may peel off between the sheets. .

■ On the other hand, in the invention of this application, the sticker □,, le, co'''mrtc*h・iQ
*(l ffit W, 4j41. Assorted wood ■□ Apply a coat of resin, coat it with a cloth, and apply a top coat of paint such as enamel or paint to the space 1 while the synthetic resin has not hardened.
Let this dry and s! including the paper space! Forms a solid coating.

The sealer that penetrates between the sheets and hardens must be selected depending on the adhesion of the enamel paint applied to the outer surface, but synthetic resins of the same type are generally suitable.

,,,.

For example, if the topcoat or paint is lanthanum enamel, the paper strengthening agent should be moisture curing board - liquid polyurethane 2.
− is suitable. In addition, when the top coat is aminoalkyd, melamine or urea alkyd N is suitable as the interpaper reinforcing agent.

In addition, in the case of resins of the same type, the one with a lower molecular weight has higher permeability.

One feature of this invention is that a commonly used acetic acid vinyl emulsion adhesive alone can be used alone, or a urea resin or the like can be mixed therein.
There is a risk of gelation of the adhesive.Productivity: Very good.Also,□External surface As for the finish, since the paper is coated with a sealer, the enamel paint applied to the outside 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 coating 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 paint.

Next, examples of the present invention will be shown.

Example/2. Apply adhesive 777@” (w s t) to the veneer □ using a spreader, and after semi-drying, paste thick thin paper onto the veneer □ using a roll press.

After thoroughly drying the surface, apply a mixed resin of Melagun 20% 1, urea λQ, and Pulquid to 1Ω.

40 4X'' (wet) was applied and dried and cured to obtain a coated plywood in which the resin between the sheets and the surface paint were integrally cured.

Example 6: Melamine 1 urea and alkyd mixed resin tube was coated on thin paper (, z, yz//m'') using a roll coater.
□After clearing and semi-drying, apply aminoalkylated
