Embodiment 1

[0029] 1, with reference to Fig. 1, a kind of production technology of decorating base paper comprises following sequential steps:

[0030] (1) After pulping the wood pulp, coarse pulp is obtained;

[0031] (2) After the coarse pulp is beaten, the fibers in the pulp are disentangled, moderately cut and divided into filaments, and then the mechanical pulp after tapping and the mixed chemical pulp after tapping are obtained;

[0032] (3) adding glue, fillers and chemical additives to the above mechanical pulp to make semi-finished pulp;

[0033] (4) After the above-mentioned semi-finished pulp is screened, screened, pressed, calendered, rolled and cut, it is made into a high-grade decorative base paper;

[0034] The technical improvement of the present invention:

[0035] (1) Design improvement of process degassing system: Due to the large amount of mechanical pulp used in the decorative base paper, the gas content and coarse and heavy impurities in the fiber suspension in th...

Abstract

The invention relates to a production process of decorative base paper. The process comprises the following steps: carrying out pulping treatment on wood pulp, thus rough pulp is prepared; carrying out pulping treatment on the rough pulp, defibering fiber in paper pulp, cutting off moderately and brooming, thus mechanical pulp after knocking and needle leaf and broad leaf mixed chemical pulp after knocking are prepared; mixing the mechanical pulp and the chemical pulp, and adding starch and auxiliary chemicals in the pulp, thus pulp is prepared; and adding auxiliary chemicals such as glue, filler after dilution, and preparing the high-grade decorative base paper after the treatment of screening, processing of a wet end, processing of a pressing section, press polishing, paper winding and rewinding and packaging. According to the invention, through the improvement of production technology and devices in the production technology, the ratio of expansion and contraction, thickness, bubble points and other using performances are improved.

Description

technical field [0001] The invention relates to a papermaking process, in particular to a production process of decorative base paper. Background technique [0002] At present, there is still a relatively large difference between the research and production of decorative base paper in my country and the advanced level abroad. Internationally, the base paper represented by Finland occupies the main market of high-end decorative paper in the world, and the domestic high-end decorative base paper market mainly relies on imports. The main market of domestic decorative base paper is domestic, occupying mainly the middle and low-end decorative base paper market, and domestic decorative base paper cannot completely replace imported base paper. The main gap between domestic base paper and imported base paper is reflected in several aspects: [0003] 1. There is a certain gap between the domestic decorative base paper and the imported base paper in terms of expansion rate and thickn...
