Example Embodiment

[0016] Example 1:

[0017] After preparing materials, 60 parts by weight of masson pine, 20 parts by weight of hardwood, and 20 parts by weight of cedar edge boards are prepared by using low-energy displacement cooking and closed washing to make chemical natural wood pulp with a Kappa number of 40. After oxygen-alkali delignification and hydrogen peroxide bleaching, the whiteness of the slurry is 19% (ISO). The slurry is adjusted to a concentration of 3.4%, the slurry is beaten to 27°SR, and the wet weight is 12g. After dilution, the sand is removed, the online concentration is controlled to 0.25%, the online pH value: 6.5, after the pressure screen, the PEA wet strength agent seasoning with the absolute dry weight ratio of 1% to the pulp, the fourdrinier paper machine forming, pressing, drying, Coiling, rewinding, and packaging into finished products.

[0020] Example 2:

[0021] After preparing materials, 50 parts by weight of masson pine, 30 parts by weight of hardwood, and 25 parts by weight of cedar edge boards are prepared by DDS displacement cooking and closed washing to make chemical natural wood pulp with a kappa value of 50. After oxygen-alkali delignification and hydrogen peroxide bleaching, the whiteness of the slurry is 26% (ISO). The slurry is adjusted to a concentration of 3.0%, the slurry is beaten to 29°SR, and the wet weight is 12.3g. After dilution, remove sand, control the online concentration to 0.22%, and the online pH value: 6.1. After the pressure sieve, the PEA wet strength agent seasoning with the absolute dry weight ratio of 4% to the pulp is used. Fourdrinier paper machine molding, pressing, and extensibility Compression, drying, coiling, rewinding, and packaging into finished products.

[0024] Example 3:

[0025] 55 parts by weight of masson pine, 25 parts by weight of hardwood, 10 parts by weight of cedar edge boards, and 10 parts by weight of plywood processing residues, after preparing materials, use DDS replacement cooking, closed washing and sieving to make a Kappa number 42 Chemical natural wood pulp. After the pulp has been delignified by oxygen and alkali and bleached by hydrogen peroxide, the whiteness of the pulp will be 27% (ISO). The pulp will be adjusted to a concentration of 4.4%, and the pulp will be beaten to 32°SR, wet The weight is 14g, the slurry is diluted and de-sanded, the online concentration is controlled to 0.2%, the online pH value: 6, after the pressure sieve, the PEA wet strength agent seasoning with the absolute dry weight ratio of 8% to the pulp, Fourdrinier paper machine Forming, pressing, extensible compression, drying, coiling, rewinding, and packaging into finished products.

Abstract

The invention provides tape base paper and a production method thereof. As for the tap base paper, the fracture length is more than or equal to 6.0km; the tensile strength is more than or equal to 1.5kN/m; the moisture content is within the range of 7-10%; the tightness is more than or equal to 0.62g/cm<3>; the wet strength is more than or equal to 0.33kN/m; and the whiteness is within the range of 17-25%. The production method of the tape base paper comprises the following steps: carrying out low-energy consumption displacement cooking, oxygen-alkali delignification and hydrogen peroxide bleaching processes on a wood fiber raw material to produce micro-bleaching pulp, wherein the whiteness of the bleached pulp is 19-27%, the beating concentration of the bleached pulp is 2.5-4.5%, the beating degree of the bleached pulp is 26-32 degree SR, and the wet weight of the bleached pulp is 10.5-15g; and the pulp is formed by beating, degritting, adding a wet strength agent, carrying out fine screening with a pressurized screen, forming on a mesh, squeezing, drying, reeling, rewinding, and packaging.

Description

technical field [0001] The invention relates to an adhesive tape base paper, which has high dry and wet physical strength and brown color, and is suitable for producing adhesive tapes. The invention also relates to the production method of the tape base paper, especially the technology of using needle and broadwood fiber raw materials, adopting DDS low energy consumption displacement cooking, oxygen delignification and hydrogen peroxide bleaching process to produce the tape base paper. Background technique [0002] In the automotive, home improvement, packaging and other industries, a tape is used for blocking or bonding. At present, the tapes on the market mainly include plastic tapes and paper-based tapes. The paper sheets used to produce paper-based tapes are required to have certain physical strength, water resistance, and aging resistance, so as to ensure the normal production and tape products during the tape processing and production process. quality. To produce tap...
