Problems solved by technology

[0002] The decorative base papers currently on the market are mainly decorative special papers used on the surface of furniture and floors. According to the requirements of users, after the surface of the base paper is printed into various designs and colors, it is then bonded to the surface by dipping and pressing. The surface of the board can beautify the board. During the dipping process, the air permeability of the base paper is very important. It directly affects the absorption speed of the base paper during the dipping process, thereby affecting the dipping speed and the air permeability of the decorative base paper. Generally around 25sec (coulee method), the highest dipping speed can only reach 30m / min, which cannot meet the requirements of high-speed dipping

Embodiment 1

[0019] Reference figure 1 The production process steps of the high-speed dipping printing decorative base paper of the present invention are as follows:

[0020] The first step: pulping, through the pulping equipment, wood pulp, titanium dioxide, pigments and water are evenly mixed to prepare a slurry with a mass percentage of 6.0%. The required raw materials include 10% by weight Softwood pulp, 60% hardwood pulp, 15% titanium dioxide, 12% kaolin and 2.5% pigment; the pigment is composed of iron oxide;

[0021] The second step: refining, through the high-speed rotating friction and squeezing of the refining equipment, so that the pulp after pulping can achieve the required cutting and splitting, and make wood pulp, titanium dioxide and pigments The mixing is more uniform and the mutual bonding is tighter. The slurry is configured into a slurry with a mass percentage concentration of 5.5%, a tapping degree of 33°SR, and a wet weight of 2.0-2.5g;

[0022] The third step: batching, f...

Abstract

The invention relates to a process for producing high-speed gum-dipping printing decorative base paper. In the process, the base paper is prepared by a pulp smashing step, a defibrination step, a batching step and a papermaking step. In the pulp smashing step, pulp at the concentration of 6.0 to 6.5 mass percent is prepared by raw materials and water, wherein the raw materials comprise 63 to 78 weight percent of wood pulp, 10 to 14 weight percent of kaolin, 12 to 18 weight percent of titanium white and 2 to 3 weight percent of pigment. In the pulp batching step, pulp at the concentration of 2.0 to 4.0 mass percent is prepared by adding 3 to 5 weight percent of wet strength agent, 0.2 to 0.4 weight percent of retention aid, 0.1 to 0.3 weight percent of alum, 0.05 to 0.15 weight percent of penetrating agent and 0.05 to 0.15 weight percent of auxiliary agent based on the weight of the pulp subjected to defibrination into the pulp subjected to defibrination. By the process, the proportionof chemical auxiliary agents in the decorative base paper process is adjusted, so that the gum dipping speed reaches more than 45m / min; therefore, the production efficiency of a gum dipping factory is improved, and the production cost is reduced.
