Technical field
The present invention relates to a kind of Packing free Polyvinyl Alcohol Combination Coating Artistic Canvas And Its Preparation Method, specifically be used for graphics art man drawing, be applicable to oil painting, acrylic painting, gouache, also can be used for decorating, decorateing, belong to the painting supply technical field.
Background technology:
Before the present invention made, in prior art, artist's drawing normally adopted traditional white coating canvas.It mainly is a direct coating white coating material on the substrate cloth.The white coating material adopts polymer emulsion such as polyvinyl alcohol, ethene acetate homopolymers emulsion, the one pack system of latex of copolymer in cinnamic acrylic ester and pure acrylic acid ester copolymer emulsion, bi-component emulsion add a greater number filler such as titanium dioxide, lithopone, talcum powder, calcium carbonate, zinc oxide etc. as the coating matrix and are mixed and made into.Then coating material is coated on and makes art canvas on the primary backing.The defective of the artistic painting canvas of this white coating is that the compactness of coated film is undesirable, usually takes place easily during drawing that the back of the body oozes, oil suction; Because contain more solid powder filler, be full of cracks, the jackknifing of coating takes place easily and peel off; The easy yellowing of white coating.The serviceability of these defective effect products and shelf life.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of high molecular polymer of different performance composite, and do not add filler and make coating material, adopt " sandwich " structure coating rubbing method of painting bottom coating, coating inter coat, coating overlay coating to be coated with into the transparent and almost transparent non-filler coat art canvas of coating, this canvas not only embodies the simple true qualities of primary backing, and serviceability also is much improved;
This canvas is not owing to contain solid powder filler and composite in conjunction with the high molecular polymer of several different performances, the flexibility of its coated film, compactness and mechanical strength are improved greatly, it can produce hardly coating be full of cracks, jackknifing, peel off, oil suction does not take place during drawing and the back of the body oozes, the light resistance of coating not at all easy generation coating flavescence and influence the Packing free Polyvinyl Alcohol Combination Coating Artistic Canvas And Its Preparation Method of product serviceability and shelf state also be difficult for to take place to change cause slack and undisciplined because of the temperature difference and humidity.
Main solution of the present invention is achieved in that
