Waterproof Inkjet Printing Engineering Blueprint Paper

Abstract

The invention relates to a paper sheet and particularly relates to waterproof ink-jet printing engineering blueprinting paper. The waterproof ink-jet printing engineering blueprinting paper comprises a three-layered structure including a surface coating, a raw paper layer and a back coating, wherein paint of the surface coating comprises silicon dioxide, blue color paste, an adhesive, a color fixing agent and a water-resistant agent; and the back coating comprises polyvinyl alcohol. Aiming at abandoning a process in the prior art of dyeing papermaking raw materials or the paper sheet, a low-quantitative coating technology is applied, and low-quantitative coating and back coating processing can be carried out on the surface of the paper sheet, so that a blue color needed by the engineering blueprinting paper is given to the surface of the paper sheet, and printing drawing information needed by the ink-jet printing engineering blueprinting paper is fine and clear; the developing property and the color fixing performance are excellent, and the paper sheet has shape stability and is not curled and deformed; the waterproof ink-jet printing engineering blueprinting paper has an equivalent waterproof property and the drawing information on the blueprinting paper is not blurred and cannot lost when meeting water, and has the properties of folding resistance, no cracking and the like; and meanwhile, the technical scheme provided by the invention does not generate wastewater in a production and machining process, and the ecological environment can be effectively protected.

Description

Technical field [0001] The invention relates to a paper, in particular to a waterproof inkjet printing engineering blueprint. Background technique [0002] Since the traditional blueprint production of diazonium salts has been upgraded to the development of computer data files directly printed by printers, the use of digital printing blueprints to replace traditional printing has been one of the important contents of today’s industrial revolution; existing applications are printing engineering drawings The paper is dyed ordinary printing paper instead of blue drawings. In the production process of this kind of technology, dyes are added to the papermaking raw materials to give the finished product the required blue color, or the white base paper is dyed to give the paper a blue effect; [0003] Defects of existing technology: [0004] 1. This kind of dyeing process needs to consume more organic dyes, and there is waste water that is harmful to the environment during the production p...

AI Technical Summary

Problems solved by technology

[0004] 1. This kind of dyeing process needs to consume more organic dyes, and there is waste water harmful to the environment in the production process

[0005] 2. Ordinary printing paper cannot improve the technical characteristics of the paper itself after dyeing and processing. The surface roughness of ordinary printing paper cannot meet the fineness requirements of engineering drawings, and it is easy to cause serious problems of missing points, lines or data in printed drawings. ; The method of improving the smoothness and roughness of the paper surface by strengthening the calendering effect will cause the contradiction of poor ink absorption and ink accumulation in printing

[0006] 3. The engineering blueprints produced by the existing technology do not have the required water resistance, and the drawings are unintentionally damp or soaked in water during application at the construction site, which may easily cause damage to the drawings or loss of data carried by the drawings

[0007] 4. The flexibility of ordinary printing paper is poor, and it is difficult to meet the requirements of machine folding of engineering drawings after printing and repeated unfolding and folding without breaking during the construction process.

[0008] CN105297546A (2016-2-3) discloses a blueprint paper and its preparation method, but the performance of the blueprint paper still needs to be improved
