Embodiment 1

[0026] Wood pulp ratio: Beimu 50% + Golden Lion 50%. This ratio is used to decompose the wood pulp through the pulping equipment (hydraulic pulper). The beating degree is 40°SR, the wet weight is 6g, and the beating concentration is 3.5%. The prepared pulp is pumped into the pulping tank for pulping. Add softener when mixing pulp, wherein the softener is stearate, the dosage is 3kg / T pulp, and add at room temperature. After stirring evenly, add wet strength agent 30kg / T every 30 minutes, filter when adding wet strength agent, and divide the wet strength agent that needs to be added into the papermaking slurry into two parts: the first wet strength agent and the second wet strength agent ;

[0027] The total amount of polyamide polyamine epichlorohydrin resin wet strength agent added is 3kg / ton of paper, which is added in two parts: one part is added to the cationic starch first, and the amount of addition is 0.12kg / ton of paper, which is relative to each ton of dry cationic ...

Embodiment 2

[0032]Wood pulp ratio: Beimu 50% + Silver Star 50%. This ratio is used to decompose the wood pulp through the pulping equipment (hydraulic pulper). The beating degree is 55°SR, the wet weight is 11g, and the beating concentration is 4.8%. The prepared pulp is pumped into the pulping tank for pulping. Add softener when mixing pulp, dosage 8kg / T pulp, add at room temperature. After stirring evenly, add wet strength agent 35kg / T every 45 minutes, the total amount of polyamide polyamine epichlorohydrin resin wet strength agent added is 5kg / ton of paper, and add in two parts:

[0033] Part of it is added to the cationic starch first, the addition amount is 0.20kg / ton of paper, relative to each ton of dry cationic starch, the addition amount is 1%, mixed with the cationic starch and then added to the pulp, the pulp after mixing Then add the remaining part of the wet strength agent (ie 4.80kg / ton of paper) and mix well.

[0034] When the wet strength agent is added, it needs to be ...

Embodiment 3

[0037] Ratio of wood pulp: Beimu 50% + Xiongshi 50%, this ratio is decomposed by pulping equipment (hydraulic pulper), the beating degree is 70°SR, the wet weight is 8g, and the beating concentration is 3.6%. The prepared pulp is pumped into the pulping tank for pulping. Add softener when mixing slurry, dosage 5kg / T slurry, add at room temperature. After stirring evenly, add wet strength agent 45kg / T every 60 minutes. When adding wet strength agent, it needs to be filtered. The total amount of polyamide polyamine epichlorohydrin resin wet strength agent added is 3kg / ton of paper, which is divided into two parts :

[0038] Part of it is added to the cationic starch first, the addition amount is 0.80kg / ton of paper, relative to each ton of dry cationic starch, the addition amount is 10%, mixed with the cationic starch and then added to the pulp, the pulp after mixing Then add the remaining part of the wet strength agent (ie 2.20kg / ton of paper) and mix well. Then pump the pre...

Abstract

The invention relates to a high strength impregnation textured paper production process including the parts of paper making and impregnation processing, paper making part comprises wood pulp defibering, grinding, pulp mixing, purification, screening, forming on a net, squeezing and wrinkling, drying, coiling and cutting, the pulp mixing is as follows: ground pulp is added with a softening agent, a wet strength agent and cationic starch, the softening agent dosage is 3-8kg / T pulp, the wet strength agent dosage is 30-45kg / T pulp; the addition of the wet strength agent and the cationic starch comprises the steps of: the wet strength agent to be added into the paper making pulp is divided into two parts of a first wet strength agent and a second wet strength agent; the first wet strength agent and the cationic starch to be added into the paper making pulp are mixed evenly to obtain a mixture; the mixture is added into the paper making pulp and mixed evenly; the paper making pulp added with the evenly mixed mixture is added with the second wet strength agent, and is evenly mixed.

Description

technical field [0001] The invention relates to a production process of high-strength impregnated masking paper. Background technique [0002] Masking paper is a high-tech decoration and spraying paper (also known as color-separation tape paper because of its special properties), which is widely used in interior decoration, spraying of household appliances and spraying of high-end luxury cars. Its color separation effect is clear and clear, and it also has arc art effect, which has brought a new technological revolution to the decoration and spraying industry, and made the industry glow with new vitality. At present, the masking paper and impregnated masking paper produced by various manufacturers still have many deficiencies, mainly reflected in the high thickness, poor flexibility and strength, and good flexibility and strength, low thickness, which cannot meet the needs of the market. Thickness requirements. [0003] Cationic starch for papermaking, that is, introducing...
