〔産業上の利用分野〕
本発明は、曇り、光沢ムラ等の外観不良のない艶消し仕
上の熱硬化性樹脂化粧板を製造する方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a thermosetting resin decorative board with a matte finish and free from appearance defects such as cloudiness and uneven gloss.
熱硬化性樹脂化粧板は、熱硬化性樹脂を塗布含浸後乾燥
した紙或いは布を重ね合わせ、当楯ヲ載せて高温高圧の
下で成形することにより得られる。A thermosetting resin decorative board can be obtained by coating and impregnating a thermosetting resin, then drying the paper or cloth, stacking them on top of each other, placing them on a plate, and molding them under high temperature and pressure.
当板としては、ステンレス鋼板、黄銅板等の金属当板、

凸を有する化粧板か得られる。As a backing plate, a metal backing plate such as a stainless steel plate or a brass plate,
Alternatively, a resin backing board or the like is used, and the appearance of the decorative board is determined by the gloss and surface shape of the backing board. If you use a metal backing plate with a mirror finish, you will get a decorative board with excellent gloss, and conversely, if you use a metal backing board with a matte finish, you will get a decorative board with no gloss. Furthermore, if a backing board with unevenness is used, a decorative board having the unevenness or the transferred unevenness can be obtained.

当板に比べ外観不良として目立ちにくいため、通常はク
ロムメッキ処理をせずに使っている。When manufacturing decorative laminates, the handling of the laminate requires great care. This is because defects such as scratches and dirt generated on the surface of the plate are transferred to the surface of the decorative plate during molding. Therefore, especially in the case of a mirror-finished contact plate, the surface of the contact plate is polished and then chrome plated to prevent scratches. - On the other hand, in the case of a matte-finished backing board, fine imperfections on the surface of the backing board are less noticeable as appearance defects than mirror-finished backing boards even if transferred to the decorative board surface, so chrome plating is usually applied. I use it without doing it.

観不良をなくすることかできなかった。However, in addition to the above-mentioned defects in appearance of decorative laminates, there are also defects due to the contamination of foreign substances, discoloration during special heating for molding,
This may be due to cloudiness or uneven gloss. Of these, the causes of cloudiness and uneven gloss cannot be identified, and even those skilled in the art are struggling to find countermeasures. For example, are methods used such as changing the molding temperature and pressure conditions, or inserting cushioning material between impregnated paper cloths?
In either case, it was not possible to eliminate poor appearance due to cloudiness or uneven gloss, which could be a deciding factor.
本発明の目的は、曇り光沢ムラ等の外観不良のない艶消
し仕上の熱硬化性樹脂化粧板を得ることにある。An object of the present invention is to obtain a thermosetting resin decorative board with a matte finish that is free of appearance defects such as cloudiness and uneven gloss.

る。The present invention is characterized by using a chromium-plated stainless steel matte backing plate when forming a thermosetting resin decorative board by overlapping paper or cloth that has been coated and impregnated with a thermosetting resin and then dried. This is a method for manufacturing a curable resin decorative board.

。Thermosetting resins used in the present invention include melamine resin, polyester resin, diallyl phthalate resin, etc., and these are used for the surface layer, and phenol resin or the same resin as above is used for the core layer. It is.

キ層を設けたものである。The chromium-plated stainless steel matte backing plate used in the present invention has a thickness L, usually 1.5 to 3.0 m.
/ m S OS 304 or other stainless steel plate is treated with a matte surface by sandblasting, etc.
A chromium plating layer with a thickness of about 5 to 20 μm is provided.

、それぞれ繰返し成形し比軸した。The present inventors used a chrome-plated backing plate and a non-chrome-plated backing plate with a matte finish, and repeatedly molded each one to perform spectrometry.

ラ等の外観不良か減るものと考えられる。As a result, it was found that using a chrome-plated backing plate dramatically reduced cloudiness and uneven gloss. The cause is not clear, but when we looked at the coefficient of linear expansion of the plate, we found that the coefficient of linear expansion of a normal stainless steel plate without chrome plating is 16 to +7.5.
X 10-@/'C or by chromium plating, the coefficient of linear expansion becomes 6 to 6.5 x 10-'/'C, which is approximately 1/3. Therefore, by chromium plating the backing plate, the elongation and shrinkage caused by heating and cooling during forming the decorative plate are also reduced. As a result, the shear stress generated in the decorative board surface resin layer in contact with the special molding plate is reduced, and it is thought that appearance defects such as cloudiness and uneven gloss are reduced.

1 of pressure was applied and heated to 150° C. for 50 minutes, and then cooled for 30 minutes to obtain a melamine resin decorative board with a matte finish and a thickness of 1.2 m/m.
