Abstract

The invention provides a preparation method of fluorescent-agent-free matt coated paper, and belongs to the field of papermaking processing. The preparation method specificallly comprises the steps: sizing on a primary color paper base, wherein the sizing is formed by blending polyethylene resin, a dispersing agent, a defoaming agent, a binding agent, nano calcium carbonate / nano titanium dioxide,a thickening agent and water. After double-sided sizing, the temperature is slowly increased to the room temperature after quick freezing, and then leveling treatment is conducted through a super calender. The art paper prepared by the method does not need a fluorescent agent to bleach a paper base, and is high in whiteness and non-reflective in paper surface. The environment-friendly and harmlessfluorescent-agent-free matt coated paper is provided for the market.

Description

technical field [0001] The invention provides a method for preparing matte coated paper without a fluorescent agent, belonging to the field of papermaking and processing. Background technique [0002] Matte coated paper, also known as matte paper, is a high-grade paper. At present, the coated paper on the market is mainly divided into basic coated paper (also called paper base), rough surface, ink absorption, suitable for writing, thin thickness, belonging to The basic product is not common in the market now. After further development on the basis, waxed coated paper appeared, with a smooth and reflective surface and a good touch. It is widely used in advertising paper and cover paper. It is one of the most widely used papers and is the follow-up product of the most common coated paper. The disadvantage is that it cannot be written on waxed coated paper. Commonly used carbon pens, fountain pens and stamps will not absorb ink and can be easily scratched and erased. Later, i...
