Abstract

PURPOSE:To promote design efficiency and weather-proofness by adding recessed and projected random patterns to the face of a metal plate, lying an adhesive layer between an only recess pattern and aggregate to stick it thereon, and coating the whole face with a finish paint film of fluoropaint. CONSTITUTION:Recessed and projected random patterns 2a and 2b are added to the face of a base material 2 such as a metal plate, etc., and an adhesive layer 3 is laid between an only recess pattern 2a and aggregate. After sticking the aggregate 4 on the adhesive layer 3, the whole face is coated with a finish paint film of fluoropaint to integrat. According to the constitution, there dimensional appearance of the projected pattern 2b and recessed pattern 2a is promoted by contrast and, at the same time, weather-proofness and pollution resistance can be promoted.

An embodiment of the highly weather resistant metal ricin plate (hereinafter simply referred to as ricin plate) according to the present invention will be described in detail below using a concave surface. FIG. 1 is an explanatory diagram showing a part of the cross section of the above-mentioned lysine board, in which the adhesive layer 3 is applied and adhered only to the concave pattern 2a of the decorative surface 5 of the base material 2 with the top lysine board. The aggregate 4 is scattered only on the pattern 2a, fixed in any desired state such as high density, etc., and a finishing coat 6 is applied to the entire decorative surface 5 including the aggregate 4.
is applied to cover the entire decorative surface 5 and integrated or on a thin board. To explain further, the base material 2 is made of an embossed plate such as a stainless steel plate, an aluminum plate, a galvanized iron plate, a colored steel plate, a titanium plate, etc. Preferably, a colored steel plate is the most desirable in terms of cost and weather resistance. An example of a cross section is the configuration shown in FIG. 2, which is formed as shown in FIG. 3. That is, the base material 2 has iron (a) as a core material, zinc metal (a), a chemical conversion coating (c), an undercoat layer (ii), and a topcoat layer (e). In this case, it is preferable that the top coat layer (E) be a coating film that has good compatibility and adhesion with the adhesive layer 3. Of course, at this time, the baking may be incomplete (baked).
If so, the adhesive layer 3 and the finish coating film 6 are integrated at the same time as baking, thereby further improving the degree of adhesion. The adhesive layer 3 is a paint whose vehicle is a component useful as an adhesive, such as acrylic resin, epoxy resin, or polyurethane resin, and ultimately exists only in the concave pattern 2a of the decorative surface 5, and is an uncured paint. This is to scatter aggregate 4 inside the house. Of course, when dispersing the aggregate 4, the convex pattern 2 on the decorative surface 5
In b, the adhesive layer 3 is not present. The aggregate 4 is made of one or more of silica sand, rock, mineral powder, zeolite, perlite, vermiculite, alumina, shirasu balloon, glass powder, metal powder, and ceramic particles, and has a size of about 1 to 250 mesh. In addition, it is more preferable that the aggregate 4 is coated or treated with a component that is compatible with the finish coating film 6 in relation to the finish coating film 6.
For example, spraying may be performed immediately after treatment with a silane coupling agent or activator. Furthermore, the finishing coating film 6 covers the entire decorative surface 5, and its composition includes, for example, acrylic resin, acrylic lacquer, acrylic urethane, ethylene oxide adduct of polyester resin and bisphenol A, or straight-set polymeric polyester. resin,
One or more of polyolefins, epoxy resins, fluoroolefin vinyl monomer copolymers, and paints containing 20 to 60 parts by weight of acrylic resins containing 85% or more of acrylic (meth)acrylate, pigments, and curing agents.
