Description

Quay and drawing pad

The invention relates to a writing and drawing surface made of a flat and/or pre-embossed valve metal foil or sheet or a compact valve metal body with a covering layer, particularly for artistic use as a drawing board in art education.

As you know, since ancient times, variously prepared original or pre-embossed and/or impregnated paper, cardboard, felt and

fabric and metal.

Nowadays, high-polyester materials are also used, which are provided with an adhesive layer and a pigment lacquer system consisting of a pigment lacquer layer and a top layer on at least one surface. Homo- or copolymers of vinyl acetate and/or cross-linking compounds and matting agents are used for the pigment lacquer system (BP 67 6öö; 119 464). Other processes aim to apply the basic colors blue, yellow and red to the paper in delicate shades or to dye it randomly, continuously (DB 2637730), or to provide the painting surface with a motif using a printing process known to itself, whereby a substance is used as the printing ink that gives the painting surface printed with the ink a different pigment holding capacity for later application.

colours (BP 75 610).

In addition, coating materials consisting of a mixture of, for example, synthetic resin paint, turpentine oil, thinner and wall metal paint as well as chalk powder, ethyl acetate and zinc white or colored pigments are used for artificial and natural painting and background materials. This is intended to give the paint or varnish the ability to withstand the effects of UV rays, and to provide the painter with the ability to draw drawing materials (BF 159667).

A universally applicable, suitable painting surface for many work techniques, which is produced without any labor or manual effort, as is known from Mont. _All of the variants shown are made of paint or varnish, with a paint layer on the outside and a paint layer on the outside, with insufficient rotting or corrosion resistance and/or color adhesion, etc. that an adhesive has to be applied or they have a stable charge, react to insufficient relative humidity, have no or insufficient capillary forces or capillary activity, are made of polyamides, are difficult to distribute the colors or are difficult to break*

The aim of the invention is to create a painting and drawing surface that is long-lasting, stable, suitable for a wide range of work tasks and can be used universally.

The invention is based on the task of creating a painting and drawing surface which has good colour fastness and capillary activity due to the chemical bond to the substrate, can be stretched without creasing, is corrosion-resistant and stable against fluctuations in relative humidity and avoids static charging.

According to the invention, the object is achieved in that a valve metal foil or sheet that is completely or partially coated with a thin, flexible and firmly adhering ceramic in the ,m area, preferably perforated on the edge (for tensioning), flat and/or pre-embossed in relief, or a compact valve metal body, preferably made of aluminum, is used.

The inventive solution for the corrosion-resistant, flame-retardant painting and drawing surface further consists in the formation of a multi-layer and/or multi-colored oxide-ceramic composite which has a high capillary activity so that the pore volumes of the layers are filled with paint or varnish to the extent of 3 % to 40 % .

The oxidized or colored particles are achieved by a quarter of the excess gas ballooning of up to 20% in the deokalohb.

The high-quality construction not only makes it possible to create a smooth, black or colored flat or reddish-colored painting surface for art lessons, but also increases the flexibility of the painting surface and achieves an adhesion of 15 to 32 microns to the metal and the paint. In addition, the microstructured surface of the oxide-ceramic coating, whose average roughness is 3.um to 50.um and promotes the adhesion of paints and varnishes, is made possible by the different migration speeds of the dye components in the

A blue metal foil 1 made of aluminum, 10/100 mm thick and 360 x 40 mm in size, perforated at the edges, is coated in a sintetok furnace by means of anodic oxidation with spark discharge in an aqueous electrolyte of the composition Na ₃ PO ₄ , Na 2 PO 4 , KMaO ₄ , 5 % each of _which is coated with an oxide-ceramic two-layer composite, whereby the white layer 2 on the metal side (adhesion promoter) is 0.8 μm thick and the oak-colored layer above it is 3 μm thick. The adhesive strength of the deocracy is 22 μm. and the average roughness 12/uau The surface thus prepared can also be fixed well in chipboard and painted well with oil paint, whereby the matt oeker-colored surface forms an excellent contrast and background and, due to the high capillary activity, ensures a smooth transition of the colors into one another. The drying time for the oil paints is due to the

A nice artistic effect is achieved by means of the floabeteon, whereby both the brown and the white parts (2 and 3) are highlighted again and contribute to the picture's composition in exactly the same way as the shiny metallic painting surface.

The designed, authentic image is framed in oil using the bottom perforation and inserted directly into the wall.
