Problems solved by technology

[0003] After the paper or cardboard absorbs the water vapor in the air, the moisture content will exceed 10%, which will seriously affect the product quality, which in turn will affect the physical indicators of the finished paper, and finally affect the sales of the finished paper
Therefore, the existing paper products will add water and moisture-proof agents during the manufacturing process to ensure the appropriate water content of the finished product, but due to the composition and chemical characteristics of the existing water- and moisture-proof agents Due to the structure, it cannot well isolate the damage of water vapor to the bonding force between paper or cardboard fibers, and it will affect the lamination processing and ink receptivity of paper while being moisture-proof. It cannot be used as an important packaging material for commodities and commodities. Paper or Cardboard Requirements

Abstract

The invention discloses a paper water-resistant moisture-proof agent which comprises a monomer, a positive ion reaction type monomer, a non-ionic reaction type monomer, a positive ion emulgator, a non-ionic emulgator and hydrophobicity aids. The mass of the positive ion reaction type monomer is 5-20% that of the monomer, the mass of the non-ionic reaction type monomer is 2-4% that of the monomer, the mass of the positive ion emulgator is 1-3% that of the monomer, the mass of the non-ionic emulgator is 1-3% the mass of the monomer, and the mass of the hydrophobicity aids is 3-10% that of the monomer. The paper water-resistant moisture-proof agent prepared according to the ratio is good in performance, the inking performance is ensured, the paper product waterproofness is ensured, and the paper water-resistant moisture-proof agent is more suitable for modern papermaking technologies.

Description

technical field [0001] The invention relates to a moisture-proof agent, in particular to a paper moisture-proof agent with a cationic structure. Background technique [0002] In the finished cardboard or paper manufacturing process, a certain amount of natural moisture is allowed inside the paper, so the dryness of the pulp must reach 90% -94% after passing through the headbox, wire section, press section, and front and rear drying sections. Or the cardboard is full of water vapor in the storage or use environment, which is relatively humid, so without any protective isolation measures, the paper with suitable dryness will absorb the moisture in the air. [0003] After paper or cardboard absorbs water vapor in the air, the moisture content will exceed 10%, which will seriously affect the product quality, and then affect the physical indicators of the finished paper, and finally affect the sales of the finished paper. Therefore, the existing paper products will add water and...
