Problems solved by technology

At present, most of the fluorescent color offset paper commonly used in China comes from imports, which are expensive
However, the production process of the fluorescent color gummed paper developed and produced in China is different from that of foreign countries. The quality of the developed and produced fluorescent color gummed paper is far inferior to that of similar foreign products, especially the appearance quality of the product is simply not comparable to that of similar foreign products, such as: Because the dehydration method of domestic paper machines adopts single-sided dehydration, while foreign countries use double-sided dehydration, so domestically produced products have defects such as large color difference between the two sides, fuzzy paper surface color, weak three-dimensional effect, and easy fading of paper. These phenomena seriously restrict domestic production. Product's market share

Embodiment Construction

[0015] 1. Beating and blending

[0016] Beat the ingredients according to the normal production organization.

[0017] In order to ensure that the produced fluorescent color offset paper has good evenness and uniformity, the beating degree is controlled between 34-42°SR. During the beating process, the beating material is first reflowed, and when the inspector detects that the beating degree of beating reaches the range required by the process, normal beating is carried out.

[0018] The slurry is mixed with 30% commercial wood pulp and 70% straw pulp. The concentration of the slurry is controlled between 3.0% and 3.5%. The dry weight of each pool of slurry is 2 tons. The prepared pulp is beaten into the pool for future use.

[0019] Straw pulp can be wheat straw pulp, reed pulp or mixed pulp of wheat straw and reed.

[0020] 2. Toning

[0021] Fluorescent color offset paper has 5 colors including fluorescent yellow, fluorescent green, fluorescent red, fluorescent powder a...

Abstract

The invention relates to a preparation method of fluorescent colorful offset paper, which comprises the steps of: completely changing the color of slurry into the required fluorescent yellow, fluorescent green, fluorescent red, fluorescent pink or fluorescent orange by utilizing several pigments, and then preparing the slurry into the fluorescent colorful offset paper according to the production procedures of finished papers of the conventional process. The preparation method of the fluorescent colorful offset paper is flexible, simple and convenient to operate and has a stable and reliable production process. The fluorescent colorful offset paper obtained through the preparation method disclosed by the invention has strong three-dimensional sense, a vivid color and an extremely good visual effect.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing fluorescent color offset paper. Background technique [0002] Fluorescent color offset paper has the characteristics of high impermeability to water and oily substances, stiff paper quality, good hand feeling, strong three-dimensional effect, good printing ink absorption, etc., has a strong book quality, and is easy to store. At present, most of the fluorescent color offset paper commonly used in China comes from imports, and its price is expensive. However, the production process of the fluorescent color gummed paper developed and produced in China is different from that of foreign countries. The quality of the developed and produced fluorescent color gummed paper is far inferior to that of similar foreign products, especially the appearance quality of the product is simply not comparable to that of similar foreign products, such as: Because the dehyd...
