Embodiment 1

[0012] 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 a softener when preparing the pulp, wherein the softener is stearate, the dosage is 3kg / T pulp, and it is added at room temperature. After stirring evenly, add wet strength agent 30kg / T every 30 minutes. When wet strength agent is added, it needs to be filtered, and then the prepared mixed slurry is pumped to the forebay for further dilution, purification, screening, and then through the headbox Spray evenly onto the forming net, remove part of the water by vacuum suction, and then transfer to the press section, wrinkle before the drying cylinder, control the wrinkle dryness to 36%, control the angle between the wrinkling scraper and the cylinder at 35°, The wrinkling speed d...

Embodiment 2

[0017] 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. When the wet strength agent is added, it needs to be filtered, and then the prepared mixed slurry is pumped to the forebay for further dilution, purification and screening, and then passed through the headbox Spray evenly onto the forming net, remove part of the water by vacuum suction, and then transfer to the press section, wrinkle before the drying cylinder, control the wrinkle dryness to 41%, control the angle between the wrinkling scraper and the cylinder at 30°, The wrinkling speed difference is 11%, and the wrinkling rate and th...

Embodiment 3

[0022] 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 the wet strength agent is added, it needs to be filtered, and then the prepared mixed slurry is pumped to the forebay for further dilution, purification and screening, and then passed through the headbox Spray evenly onto the forming net, remove part of the water by vacuum suction, and then transfer to the press section, wrinkle before the drying cylinder, control the wrinkling dryness to 45%, control the angle between the wrinkling scraper and the cylinder at 25°, The wrinkling speed difference is 20%, and the wrinkling rate and thickness can be controlled...

Abstract

The invention relates to a masking tape making and macerating process for manufacturing a masking tape, in particular to a manufacturing process for macerative masking tape. The process comprises two parts including a masking tape making part and a macerating part, wherein the masking tape making part comprises the steps as following: wood pulp untwining; pulp milling, that is, wood pulp is pulped via a double-disc refiner, wherein the beating degree is 40-70 degrees SR, the wet weight is 6-11 g, and the beating intensity is 3.5-5.0 percent; pulp preparation means that a softening agent and a wet strength agent are added into milled pulp, the use level of the softening agent is 3-8 kg / T and the use level of the wet strength agent is 30-45 kg / T; purification; screening; shaping on a net; grinding and cockling, wherein the grinding dryness degree is controlled within a range of 36-45 percent; drying; and winding and cutting. The macerating part comprises the steps of unwinding, macerating processing, drying, winding, cutting, winding, packing and warehousing. The macerative masking tape has good flexibility, high intensity and large thickness.

Description

technical field [0001] The invention relates to a masking paper-making process for making masking tape and a masking paper impregnation process, in particular to a production process for impregnating the 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 nee...
