Problems solved by technology

[0004] At present, the art paper produced by ordinary papermaking technology can play a good artistic effect in practical applications, but it is not completely satisfactory for the long-term storage of art works. Due to the change of air humidity or the acidity and alkalinity of the storage environment, The corrosiveness of the paper quality of art works is enhanced, so it is necessary to develop an anti-corrosion art paper to solve this problem

Embodiment 1

[0019] A preparation method of corrosion-resistant art paper, said preparation method comprising the following steps:

[0020] (1) Preparation of slurry: Put the trees or waste paper from which impurities have been removed into a shredder for mixing and crushing, then add water 100 times the weight of the crushed material, mechanically stir for 2 hours at a speed of 240r / min, and then add the weight of water 0.1 times the powdered ammonium sulfate continues to stir and mix. During the stirring and mixing process, the temperature is raised to 60°C, and the temperature is maintained for 10 minutes. After being bleached by alkaline bleaching process, beating with a beater, the beating degree is controlled at 40OSR, and the pretreatment is obtained. Good slurry, spare;

[0021] (2) anti-corrosion treatment: add 1% corrosion inhibitor of slurry weight, 3% sodium carboxymethyl cellulose, 0.05% titanium dioxide, 0.1% fire retardant, 0.8% to the slurry prepared in step (1) Antibacter...

Abstract

The invention discloses a preparation method for anticorrosion art paper. The preparation method comprises the following steps that firstly, a sizing agent is prepared, wherein trees or waste paperis mixed and smashed, auxiliary materials are added, stirring, bleaching and beating are carried out, and the sizing agent is prepared for use; secondly, anticorrosion treatment is carried out, wherein corrosion inhibitor, sodium carboxymethylcellulose, titanium dioxide, fire retardant, an antibacterial agent and flexibilizer are added, and after stirring is carried out, pulp grinding is carried out; thirdly, paper forming is carried out, wherein the mixed sizing agent is subjected to drying, hot rolling, press polishing, drying, clipping and packaging, and the anticorrosion art paper is prepared. The prepared anticorrosion art paper can resist damage of corrosive chemical products in the environment to work of art, the preparation method is simple, operation is easy, the prepared paper is high in specific strength and high in specific modulus, resistant to chemical corrosion, low in coefficient of thermal expansion and moderate in permeability and can be widely applied to the field of art paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and specifically relates to a method for preparing corrosion-resistant art paper. Background technique [0002] The production of general art paper is divided into two basic processes: pulping and papermaking. Pulping is to use mechanical methods, chemical methods or a combination of the two to dissociate plant fiber raw materials into natural pulp or bleached pulp. Papermaking is the process of combining pulp fibers suspended in water into paper sheets that meet various requirements. [0003] Paper mills generally need to store enough raw materials for 4 to 6 months, so that the raw materials undergo natural fermentation during storage to facilitate pulping and ensure continuous production of the paper mill. Cut reed, wheat straw, wood and other raw materials into flakes (for the production of chemical pulp) or wood chips (for the production of groundwood pulp) in the material preparation s...
