Embodiment 1

[0014] Taking the manufacture of white decorative base paper as an example, increase calcined kaolin and reduce the proportion of titanium dioxide. The specific weight percentages of raw materials are: proportion of calcined kaolin: 12%; proportion of titanium dioxide: 23%; proportion of pulp: 65%.

Embodiment 2

[0016] Taking the manufacture of light-colored (light yellow, light brown) decorative base paper as an example, increase calcined kaolin and reduce the proportion of titanium dioxide. The specific weight percentages of raw materials are: proportion of calcined kaolin: 12%; proportion of titanium dioxide: 18%; proportion of iron oxide yellow: 10% %; iron oxide red ratio: 1.3%. Pulp ratio: 58.7%.

Embodiment 3

[0018] Taking the manufacture of dark (brown red, dark brown) decorative base paper as an example, increase calcined kaolin and reduce the proportion of titanium dioxide. The specific weight percentage of raw materials is:

[0019] Calcined kaolin ratio: 14%; titanium dioxide ratio: 5.5%; iron oxide yellow ratio: 10%; iron oxide red ratio: 14%; pulp ratio: 56.5%.

[0020] The production process of the invention is the same as that of the prior art, and series products of several colors can be produced by adjusting the ratio of raw materials.

Abstract

The invention relates to a method for improving the overall performance of decorative base paper, belonging to the technical field of paper making. In the method, the ratio of calcined kaolin is increased, and the ratio of titanium dioxide is reduced. The formula of white decorative base paper comprises the raw materials of calcined kaolin, titanium dioxide and paper pulp; the formula of light-colored decorative base paper comprises the raw materials of calcined kaolin, titanium dioxide, iron oxide yellow, iron oxide red and paper pulp; and the formula of dark-colored decorative base paper comprises the raw materials of calcined kaolin, titanium dioxide, iron oxide yellow, iron oxide red and paper pulp. The calcined kaolin used in the invention is in a porous unformed microgranular structure and has a smaller volume weight in comparison with the titanium dioxide. Thus, for the decorative base paper made from the calcined kaolin, the loose depth, air permeability, paper penetrability and gum dipping performance are obviously improved, the printing applicability is enhanced, the consumption of the titanium dioxide is reduced, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of papermaking. Background technique [0002] Decorative base paper is one of the special products of the paper industry. It is mainly used to process and manufacture various furniture panels, laminate flooring, fireproof panels and other decorative materials. Excellent decorative base paper should have good covering performance and absorption performance. For printing decoration Base paper should also have good printing adaptability. [0003] Decorative base paper (also known as titanium dioxide paper) uses a large amount of precious chemical raw material titanium dioxide (commonly known as titanium dioxide), which accounts for about 30-40% of the weight of decorative base paper, so its manufacturing cost is relatively high. Moreover, titanium dioxide has a large bulk density, which restricts the improvement of paper bulk performance and absorption performance. Contents of the invention [0004] The pur...
