Waterproof official printing paper and processing method of same

Abstract

The invention discloses waterproof official printing paper and a processing method of same. The printing paper includes two fiber paper layers, two waterproof coating layers, and a nano-active carbonlayer. The two waterproof coating layers are respectively arranged on the outer surfaces of the upper and lower fiber paper layers, wherein the inner surfaces of the upper and lower fiber paper layersare laminated with the nano-active carbon layer through an adhesive. The waterproof coating layers are prepared from, by mass, 80-100 parts of polyurethane modified acrylate photo-curable resin, 60-70 parts of vinyl-ethyl acetate copolymerization emulsion, 20-30 parts of hydrophobic zeolite, 10-13 parts of deionized water, 4-5 parts of an inorganic thickness regulator, 2-4 parts of a defoamer, 2-3 parts of a wetting agent, and 1-2 parts of a water repellent. By means of the waterproof coating layers and the nano-active carbon layer, the product has excellent waterproof effect and excellent ink absorption capacity, so that the printing quality and ink absorption effect of the printing paper are excellent.

Description

technical field [0001] The invention relates to the technical field of printing paper processing, in particular to waterproof office printing paper and a processing method thereof. Background technique [0002] Printing paper refers to a kind of paper used for printing and copying documents. The specifications are A0, A1, A2, B1, B2, A4, A5, etc. The commonly used A4 paper is widely used in test papers. The ink-absorbing ability and color-fixing ability of the existing printing paper are not very ideal. After inkjet printing, the handwriting will fade after a period of time. However, people often need to use printing paper in damp places in practical applications. Such printing paper has no waterproof function, which brings a lot of inconvenience to actual use. [0003] Therefore, the present invention proposes a waterproof office printing paper and a processing method thereof to solve the above-mentioned existing problems. Contents of the invention [0004] The object o...
