CONSTRUCTION METHOD FOR PRINTING ON SHEET SUCH AS FILM BY USING CONCRETE SURFACE SETTING RETARDER AS INK BASE STOCK IN CONNECTION WITH TECHNIQUE FOR FORMING DECORATIVE CONCRETE BY USING CONCRETE SURFACE SETTING RETARDER

摘要

PROBLEM TO BE SOLVED: To provide a technique for printing on a sheet such as a film by using a concrete surface setting retarder as an ink base stock, which is related to the technique for forming decorative concrete using the concrete surface setting retarder and which is suitable for forming the decorative concrete by improving such a weak point that the majority of the conventional concrete surface setting retarders are soluble in water and have so weak adhesive power as to be inevitably modified and used for printing and fine edging is hardly performed, when a figure or a picture pattern such as a photograph is printed on the sheet such as the film by using the concrete surface setting retarder as the ink base stock and the printed sheet is stuck to a molding flask.;SOLUTION: The concrete surface setting retarder which is insoluble in water and soluble in alkali and has both of firm adhesive power and drying property as an ink, is applied and screen printing is adopted as a printing method, so that a coating film having the thickness, fineness and suitability for forming the decorative concrete, which are characteristics of the printing method, can be printed.;COPYRIGHT: (C)2012,JPO&INPIT
