preparation example Construction

[0028] like figure 1 , The present invention provides a method of preparing a translucent paper with a graphic, comprising the steps of:

[0029] Prepare the original paper to control the wet strength of the original paper;

[0030] Configuring alkyl ketene dimer (of AKD) glue is applied, by screen or gravure printing process graphic graphic printing process glue is applied to the printing base paper, to give after drying glue applied graphic printed paper ;

[0031] The graphic printed paper glue is applied sequentially gel process, deacidification treatment, a washing treatment and a neutralization treatment plasticized, after the drying process to obtain a translucent paper with a graphic.

[0032] In particular, the concentration of alkyl ketene dimer (of AKD) 0.5 to 1.5% of the applied glue.

[0033] In particular, a method for controlling wet strength paper in papermaking is added during the preparation of the base paper wet strength agent, wet paper strength agent is 2.0-2....

Abstract

The invention relates to the field of paper preparation, in particular to a method for preparing translucent paper with graphics and text and the translucent paper with graphics and text. The method includes the following steps: preparing base paper, controlling the wet strength of the base paper; configuring alkyl ketene dimer sizing solution, printing the sizing solution on the base paper by screen graphic printing process or gravure graphic printing process, and drying Obtain the base paper printed with sizing liquid graphics; the base paper printed with sizing liquid graphics is sequentially subjected to gelation treatment, deacidification treatment, washing treatment, neutralization treatment and plasticization treatment, and after drying treatment, the base paper with graphics and texts is obtained. translucent paper. The translucent paper with pictures and texts prepared by the method for preparing translucent paper with pictures and texts of the present invention makes the translucent paper have pictures and texts after the translucent paper is prepared, and meets the requirements of food-grade packaging, and at the same time, the process is simple and convenient for preparation .

Description

Technical field [0001] The present invention relates to the field of preparing paper, particularly preparation relates to a translucent paper with a translucent paper with a graphic and graphic. Background technique [0002] Existing there are three translucent paper, glassine paper for the first, is the use of certain water-containing wet paper sheet through a super calendar paper pressure tight manner is formed; the second is a tracing paper, is the use of after the sulfite pulp-like high viscosity taken into beating copied paper; parchment third plant using sulfuric acid gelled way that paper fibers to produce gelled denatured form. Translucent paper produced according to the above-described three methods, namely by different processes, all of the entire paper became translucent effect. [0003] The above three translucent paper webs are formed integral translucent paper, when the paper needs to have graphic translucent, semi-transparent paper required for printing. However, f...
