Abstract
Compositions and a method are provided for forming a coated wood, plastic or metal product having the appearance and texture of wood grain. The joints on a wood surface are concealed by the coating and the coating is capable of accepting conventional wood stain.
Description
This application is a divisional application of Canadian patent application No. 612,951 filed on September 25th, 1989.
WATER-REDUCIBLE COATING COMPOSITION
AND PROCESS OF USE THEREOF
The parent invention is directed to a method and compositions used therewith for coating wood, metal or plastic to render it capable of receiving wood-grain printing inks and conventional wood stains, while also concealing joints and other imperfections.
In the decorative uses of wood, there are many applications in which visible joints in the wood are not desired. For example, in the use of moldings along the edges of doors, window frames, and the like, it is desirable to have each edge constructed of a single length of wood. Moreover, to have a decorative effect, the wood is often stained to a desired color, such as walnut, rosewood, and the like, then covered with a protective coating such as varnish or other conventional clear coating. The use of single lengths of wood is expensive and wasteful, since short lengths of scrap wood are not reusable. There is no practical alternative to using single lengths of wood for molding. Plastics or compounded wood pulp products are usually not desirable since they either do not have sufficient strength and durability or do not have the pleasing wood grain surface texture. A piece ofplywood would also be extremely expensive since one or more surfaces of the molding would have to be veneered, making it much more expensive than a solid piece of wood.

WATER-REDUCIBLE COATING COMPOSITION
AND PROCESS OF USE THEREOF
The parent invention is directed to a method and compositions used therewith for coating wood, metal or plastic to render it capable of receiving wood-grain printing inks and conventional wood stains, while also concealing joints and other imperfections.
In the decorative uses of wood, there are many applications in which visible joints in the wood are not desired. For example, in the use of moldings along the edges of doors, window frames, and the like, it is desirable to have each edge constructed of a single length of wood. Moreover, to have a decorative effect, the wood is often stained to a desired color, such as walnut, rosewood, and the like, then covered with a protective coating such as varnish or other conventional clear coating.

Plastics or compounded wood pulp products are usually not desirable since they either do not have sufficient strength and durability or do not have the pleasing wood grain surface texture. A piece ofplywood would also be extremely expensive since one or more surfaces of the molding would have to be veneered, making it much more expensive than a solid piece of wood.

The use of scrap pieces of wood joined together, such as by finger joints, would be desirable. There has been difficulty however, in treating joined pieces of wood to have the appearance of a single piece of wood for decorative purposes. One such method is described in commonly assigned Patent No. 4,546,133, wherein specialized wood coating and ink compositions are disclosed. The present invention provides an improved method and coating for metal or plastic to impart wood-like appearance, or for concealing joints in wood, while still maintaining the appearance and texture of a single piece of wood. The coating according to the present invention also is capable of accepting conventional wood stains.
The present invention therefore seeks to provide water-reducible compositions which are useful for coating metal or plastic to impart a wood-like appearance, or for coating wood to conceal joints, but which retain the grainy appearance of the natural wood.
The present invention also seeks to provide novel coatings for metal, plastic or wood which accept conventional wood stains.
The invention will be apparent from the following description and preferred embodiments.
The method of the parent application utilizes a base-coat composition for covering plastic, metal, wood or a wood product comprising a combination of resins, pigments, solvents, and additives for suspension, dispersion, thickening, flowing and defoaming. In the invention of this divisional application a printing composition is also provided comprising resin, -3_ ~339588 pigments, solvents, and anti-foaming and wetting agents.
The method according to the present invention comprises the steps of applying a novel liquid basecoat onto metal, plastic/ natural wood or a wood product, evaporating volatile solvents to form a solid coating, and applying a novel ink composition in a wood grain pattern onto the solid coating.
The starting material for forming a coated product may be any product having a plastic, metal or wood surface, including strips, with or without joints, sheets, including plywood and wood grain paper, or any other product derived from wood or wood pulp, sawdust, and the like. Since a primary purpose for the use of the compositions according to the present invention is to provide a decorative surface, it is desirable, but not necessary, that the starting material have a wood grain texture, since that texture will be substantially retained after the basecoat coating is applied.
Generally, the metal, plastic, wood or wood product will be coated with a liquid basecoat composition then dried to remove the volatile solvents. The drying is preferably performed with heat in a conventional oven, but other evaporative methods may be utilized. Then a grain ink formula-tion may be applied in a pattern to simulate a wood grain using a conventional roller having a wood grain pattern using the inks described herein. Apparatus for performing these functions are conventional and known in the art.
~4~ 1339~88 The basecoat formulation according to the present invention comprises the following components:
acrylic resins, styrene-maleic anhydride resins, pigments and fillers, thickener, flow agents, defoaming agents and solvents.
In general, the water-reducible basecoat, according to the invention will contain the following:
% by volume Water 20-30 10 Organic solvents 1-5 Styrene-maleic anhydride resins 0.5-3 Acrylic resins 45-~5 Pigments and inorganic fillers 10-20 organic thickener up to 1 15 Defoaming agents up to 3 Flow agents up to 5 Suspension agent up to 1 Nut shell flour 1-5 A particularly preferred basecoat composition useful for coating wood contains the following (percentages given by volume).
~ ~y volume Water 23.50 Organic solvents 1.72 25 Styrene-maleic anhydride resins 0.8 Acrylic resins 51.10 Pigments and inorganic fillers 15.98 organic thickener 0.17 Defoaming agents 1.02 30 Flow agents 3 33 Suspension agent 0.18 Nut shell flour 2.20 In a preferred formulation, the acrylic resins and styrene-maleic anhydride resins are the commercially ~5 available resins Joncryl 89 (Johnson & Johnson), Rhoplex AC-~07 (~ohm & Haas), and SMA-1440 (Sartomer Company).
Absorption pigments and inert fillers which may be utilized include commercial pigments such as *Trade-mark * ~5~ 1~9588 Asbestine 325 (U.S. Mica), titanium dioxide, talc, Hitox (Benilite), and the like. The composition will also contain an organic pigment, pecan shell flour, preferably ground to an average size of about 40 micron.
The base coat composition will also contain suspension agents, thickeners, flow agents and defoaming agents. Suspension agents include Colloid 711 made by Colloid Co. A preferred thickener is Cellosize, made by Union Carbide. Flow agents such as Minusil (P.G.S., Inc.), Super Adit*(Nuodex) may ~e utilized. Defoaming agents such as Surfynol (Air Products) may be used.
Typical organic solvents include dimethyl ethanol, carbitol (diethylene glycol monomethyl ether) methyl ethyl ketone, acetone, MIBK (methyl isobutyl ketone), methyl and ethyl alcohol, ethyl acetate, amyl acetate, and the like. The several portions of any vehicle used in comparing one of the decorative coatings are generally composed of the same ~asic materials although they may have varied amounts of thinners, solvents, fillers and the like so as to vary their viscosities and other physical properties, but there may ~e a com~ination of unrelated resins used on the same panel to provide texture and growth lines.
