Embodiment 1

[0020] Example 1 120g / m 2 Production of anti-counterfeiting translucent art paper with indentation of Li Baidou wine picture.

[0021] (1) Selection and treatment of raw materials Coniferous wood pulp, hardwood pulp, SWP fiber, and PE powder are selected as raw materials. The absolute dry weight of softwood pulp in raw materials is 20%, hardwood pulp is 20%, and SWP fiber is 40%. PE powder is 20%. Specifically, 600kg of coniferous and broadleaf mixed pulp, 600kg of SWP fiber, and 300kg of PE powder. The coniferous wood pulp and hardwood pulp are put into the hydraulic pulper at a ratio of 1:1 for crushing. After crushing, the pulp is beaten by a large taper beater. The beating concentration is 6.0%, and the beating degree is 30. o Sr. Put the SWP fiber into the trough beater, the beating concentration is 3.0%, beating in the first 60 minutes by light to loosening method, and the fiber is cut and beating by the heavy knife in the last 60 minutes, the total beating time is 12...

Abstract

The invention relates to a manufacturing method of art anti-counterfeiting paper with semitransparent press marks. Softwood pulp, hardwood pulp, SWP fibers and PE powder are selected as raw materials, the treated softwood pulp and hardwood pulp are mixed with SWP fibers dispersed into single fibers, the PE powder is added and stirred for mixing, and then boiled cationic starch of 2.5% and the PAE wet strength agent of 2.0% are added; the mixed pulp is fed to a paper machine through a pulp flowing system to make paper, and paper machine squeeze dewatering, drying before sizing, surface sizing, drying after sizing, calendaring and rolling are carried out to complete the papermaking process; embossing is carried out on the raw paper obtained through processing, the surface temperature of a carving textured roll is 150-200 DEG C, the embossing work pressure is 4.0-10.0 MPa, the machine speed is 10-50 m / min, and production of the art anti-counterfeiting paper with the semitransparent press marks is completed. The art anti-counterfeiting paper with the semitransparent press marks is easy to manufacture and process, the production technology is reliable, and operability is high.

Description

technical field [0001] The invention relates to the field of artistic anti-counterfeiting paper, in particular to a production method of artistic anti-counterfeiting paper that uses heating and pressure to form a translucent effect on the surface of the paper. Background technique [0002] Watermark anti-counterfeiting paper is a kind of paper for the public to identify anti-counterfeiting technology. Because it is easy to identify and difficult to forge, it has been widely used in anti-counterfeiting in various fields such as securities and bills. The watermark is formed by displacing the fiber before the paper is formed by the watermark roller, and forming different layers of light and dark by the fiber displacement, thereby forming a watermark. The part with a lot of fiber forms a black watermark, and the part with a small amount of fiber forms a white watermark. The formation of the watermark roller is formed by pressing screen technology or welding technology. Limited b...
