Waterborne copy paper and preparation method thereof

Abstract

The invention discloses a piece of waterborne copy paper and a preparation method thereof. The waterborne copy paper is prepared from the following components in parts by weight: 20-55 parts of reed pulp, 4-9 parts of a vinylon binder, 33-66 parts of wood pulp, 1-10 parts of a dispersing agent, 10-18 parts of synthetic resin, 3-5 parts of phloem fibers, 5-25 parts of titanium dioxide, 1-7 parts of carbon black, 7-15 parts of polyvinyl alcohol, 10-13 parts of kaolin, 1-3 parts of resin glue, 1-3 parts of glycerine, 0.3-0.7 part of salinized sodium, 1-3 parts of polyvinyl acetate emulsion, 0.5-3 parts of white nano pigment pulp, 0.7-1.9 parts of a solidifying agent and 0.1-0.8 parts of a crosslinking agent. The waterborne copy paper adopts reed pulp, wood pulp and phloem fibers as main raw materials when being prepared, and the vinylon binder, titanium dioxide, the crosslinking agent and various dispersing agents are combined, so that the prepared waterborne copy paper has high bending strength, small deformation, good colour fastness and good colour saturation stability; and a protective layer is increased on a developing mixture of the paper, the copy paper can be repeatedly used for multiple times, and effect of the developing mixture cannot be influenced.

Description

technical field [0001] The invention relates to a composite water writing paper and a preparation method thereof. Background technique [0002] A large number of trees have been cut down, and the shortage of paper has become increasingly serious, and the waste of paper is also quite large. Because the existing writing paper is disposable, it is difficult to achieve the repeated use of paper, and there have been papers used several times in the market, but they have not been widely promoted due to the complicated production process, high cost and unguaranteed quality. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite water writing paper which is easy to make, high in quality, low in cost and can be written repeatedly. [0004] In order to solve the above problems, the present invention is achieved through the following technical solutions: a composite water writing paper, the composite water writing ...
