Problems solved by technology

The color of glassine paper comes from the base paper. The color of the base paper is usually produced by adding dyes to the slurry in the production of base paper. Due to the low retention rate of the dyes, the discharged sewage has a high color and brings great environmental impact. Pollution
The cost of dyes before merger is too high

Embodiment 1

[0018] A kind of environment-friendly color glassine base paper of the present invention, this environment-friendly color glassine base paper is made up of following proportioning composition: softwood wood pulp 155 parts, hardwood pulp 155 parts, polyethylene 2.5 parts, clear water 10000 parts, dispersant 2.3 parts, 4 parts of alkyl ketene dimer, 2.7 parts of polyester modified dimethicone, 5 parts of dryer stripper, 7 parts of rosin, 3 parts of weathering dye, 7 parts of sulfate and bast fiber 33 servings.

[0019] The preparation process of the environmentally friendly colored glassine base paper is as follows:

[0020] 1) Extract 155 parts of softwood pulp, 155 parts of hardwood pulp, 2.5 parts of polyethylene, 10000 parts of clear water and 7 parts of sulfate by weight and perform beating;

[0021] 2) Extract 2.3 parts of dispersant, 4 parts of alkyl ketene dimer, 5 parts of drying cylinder stripping agent, 7 parts of rosin and 33 parts of bast fiber according to the wei...

Embodiment 2

[0029] It differs from Example 1 in that the environmentally friendly colored glassine base paper is made up of the following proportioning components in parts by weight: 85 parts of softwood pulp, 85 parts of hardwood pulp, 0.2 part of polyethylene, 5000 parts of clear water, dispersant 1 1 part of alkyl ketene dimer, 1 part of polyester modified dimethicone, 2 parts of dryer stripper, 3 parts of rosin, 1 part of weathering dye, 1 part of sulfate and 11 parts of bast fiber share.

Embodiment 3

[0031] It differs from Example 1 in that the environmentally friendly colored glassine base paper is made up of the following proportioning components in parts by weight: 125 parts of softwood pulp, 125 parts of hardwood pulp, 1 part of polyethylene, 8888 parts of clear water, 2 parts of dispersant 2 parts of alkyl ketene dimer, 1.5 parts of polyester modified dimethicone, 3 parts of drying cylinder stripper, 5 parts of rosin, 2 parts of weathering dye, 4 parts of sulfate and 22 parts of bast fiber share.

Abstract

The invention discloses environment-friendly colorful glassine raw paper and a preparation method thereof. The environment-friendly colorful glassine raw paper is prepared from the following ingredients in parts by weight: 85 to 155 parts of needlebush pulp, 85 to 155 parts of broadleaf wood pulp, 0.2 to 2.5 parts of polyethylene, 5000 to 10000 parts of clean water, 1 to 2.3 parts of dispersing agents, 1 to 4 parts of alkyl ketene dimers, 1 to 2.7 parts of polyester modified dimethyl polysiloxane, 2 to 5 parts of dryer peeling agents, 3 to 7 parts of rosin, 1 to 3 parts of weather resistant dye, 1 to 7 parts of sulfate and 11 to 33 parts of bast fiber. In the preparation process of the environment-friendly colorful glassine raw paper, the needlebush pulp, broadleaf wood pulp, polyethylene,dispersing agents, rosin, weather resistant dye, sulfate and bast fiber are used as materials; the intensity and the toughness of the raw paper are improved; the raw paper is dyed on a surface glue applicator, so that the dye retaining rate reaches 100 percent; a better environment-friendly effect is achieved in the production process.

Description

technical field [0001] The invention relates to an environment-friendly colored glassine base paper and a preparation method thereof. Background technique [0002] Glassine paper has the characteristics of high strength, good toughness, good water resistance and oil resistance, so glassine paper is widely used in food, medicine and other industries, and can also be used for high-speed automatic labeling special tapes, laser anti-counterfeiting labels, etc. With the development of society and the improvement of people's living standards, people's requirements for the color of glassine paper are also increasing, from only requiring one kind of white to requiring various colors. The color of glassine paper comes from the base paper. The color of the base paper is usually produced by adding dyes to the slurry in the production of base paper. Due to the low retention rate of the dyes, the discharged sewage has a high color and brings great environmental impact. Pollution. The c...
