Manufacturing method for decorative raw paper

Abstract

The invention provides a manufacturing method for decorative raw paper and relates to the field of papermaking. The decorative raw paper comprises a front half part and a rear half part, wherein the front half part is at least prepared by mixing wood pulp with cotton pulp, titanium dioxide, kaolin and wet resin; the rear half part is at least prepared by mixing wood pulp with cotton pulp, titanium dioxide, kaolin and wet resin; the front half part and the rear half part are subjected to the steps of feeding, pulping, de-slagging, sizing, papermaking, squeezing, drying and polishing and then are prepared into the decorative raw paper. Compared with the prior art, the method provided by the invention has the advantages that the strength, water absorption and toughness of the whole paper sheet are enhanced by mixing wood pulp and cotton pulp with the slurry, the expansion rate of the decorative raw paper in a transferring dipping process is guaranteed, the decorative raw paper is prevented from deforming and discoloring after long-term use, the decorative raw paper is still firm after the decorative raw paper is combined with a plank for a long time, and meanwhile, other performances of the decorative paper sheet are not influenced.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to the manufacture of decorative base paper. Background technique [0002] The decorative base paper produced by upstream manufacturers needs to be printed and impregnated by downstream manufacturers to form a veneer. During the impregnation process, due to the filling of water and melamine, the transverse width of the decorative base paper will vary to varying degrees. If the lateral expansion rate of the decorative base paper is too large, it will lead to the distortion of the pattern on the printing base paper, inaccurate registration, and out-of-synchronization of the pressing plate. According to statistics, the lateral expansion rate of decorative base paper produced in my country is generally greater than 2%, which has affected the image quality at this time. Therefore, high-end decorative base paper is monopolized by foreign companies. In order to solve the problem of excessive lat...
