Stone plate mural paintingThe present invention relates to a kind of mural painting of making of slate material, especially do the mural painting that base material is done with natural stone slab material such as granite or marble.
At present, the mural painting form that has occurred has the Beijing enamel mural painting, forms such as Beijing enamel mosaic mural, glass Mosaic mural painting, frescoes of glass steel, polypropylene mural painting.The polypropylene mural painting is to make picture on the paper or on the cloth, then drawing paper or the painting canvas finished are being mounted on materials such as plank.Though this mural painting form can show various painting skills well, make the fine and smooth nature of mural painting, but because mounting process be with paste with drawing paper or painting canvas is sticking mounts on plank, drawing paper or painting canvas are exposed in the air fully, be subjected to the erosion of airborne moisture and various soda acid compositions, be difficult for preserving; Burn as water logging, or artificial the scuffing, paper or cloth are destroyed.The Beijing enamel mural painting, though Beijing enamel mosaic and glass Mosaic mural painting can long preservation, but these three kinds of mural paintings all have a common shortcoming: the lines and the form that promptly only are suitable for showing simple coarse, be difficult to bring into play on the present frame and paint, various painting skill showed enriches the form of expression as traditional Chinese Painting, oil painting, watercolor etc., made the form of expression of mural painting comparatively simple.Frescoes of glass steel is to do aggregate by blinding or glass fibre, adds unsaturated polyester resin and makees adhesive, makees picture in the above after making substrate.Because of containing higher organic material in the substrate, make sheet material easily produce be full of cracks, warpage, be unsuitable for the mural painting of large format.Because of substrate is the artificial stone, the texture of no lithotome in the picture is so decorative effect is not good again.
The purpose of this invention is to provide a kind of novel mural painting that can overcome above-mentioned shortcoming, it not only can use the various skill and technique of painting on the frame to show the drawing content, but also shows the grain effect of lithotome on picture.
The object of the present invention is achieved like this: select natural marble or natural granite for use, with the very strong unsaturated polyester resin of paper fibre penetration is mounted the paper rough sketch above above-mentioned slabstone base material, be pellucidity after making the paper fiber inhale full resin, and the picture inking partly is subjected to the mass colour resistance when opaque, there is not the blank sheet of paper part of pen and ink transparent fully like this, exposed the texture of slabstone base material, inking part pattern color is constant, and picture pattern is mounted fully on the slabstone substrate surface.In order to strengthen the adhesion strength of unsaturated polyester resin and slabstone substrate surface, added an amount of epoxy resin in the insatiable hunger resin, add styrene and can improve the resin flow performance, thereby improved the ability of soaking into of resin.In order to improve the physicochemical property of heat-resistant fireproof, can add the fire retardant amine oxide.Owing to added above-mentioned raw materials in unsaturated-resin, it is strong to make resin become cohesive force, the modified unsaturated polyester resin that erosion resistance is strong.
Owing to adopted such scheme, not only can make the various skill and technique of painting on the frame be applied to freely in the mural painting creation characteristics and the mural painting that lithotome is smooth, hard, gloss is pure organically is combined as a whole.Because drawing paper has been had the complete Bao Rong of unsaturated polyester resin of waterproof, anti-aging, acid-proof alkali ability, make mural painting itself also have the ability of waterproof, anti-aging, anti-soda acid.In addition, because the blank parts of rough sketch can present transparent effect, the natural texture that has exposed lithotome, the artistic effect of this native texture organically combines with the composition of drawing and color, and the artistic effect that makes mural painting is considerably beyond present existing mural painting kind.
Example of the present invention is described as follows: the slabstone base material is simultaneously polished remove the performance greasy dirt after the alligatoring, and rinse well with clear water, the modified unsaturated polyester resin for preparing is brushed on slabstone, the paper rough sketch lies against on the slabstone of having brushed resin, after treating the abundant infiltration resin of paper rough sketch, dacron chip base is placed on above the rough sketch, flattens, throw off dacron chip base after the drying with roller.Binding agent is a modified unsaturated polyester resin, is the mixture of A, two kinds of components of B.
A component: unsaturated polyester resin 100
Initator 2-4
Promoter 1-4
The rare 3-6 of benzene second
Fire retardant 2-6
B component: epoxy resin 6-10
Curing agent 5-8
After mixing, two kinds of components of A and B are the adhesive of mounting system usefulness.
