Problems solved by technology

The sulfuric acid paper prepared by this method is solid, dense and translucent, but its surface is very rough and has poor flatness, and the smoothness is generally less than 90 seconds
When sulfuric acid paper is used for packaging printing, there are defects such as poor color reproduction, inability to adapt to fine dot printing, and insufficient barcode recognition clarity, which greatly limits its application in the printing field; at the same time, due to the loose fiber structure on the surface of sulfuric acid paper , also greatly reduces its light transmission performance, and cannot make its packaging products have the transparency they should

Abstract

The invention discloses a high light-transmitting fiber glass surface paper, which comprises sulfuric acid paper, and the two sides of the sulfuric acid paper are coated with an undercoat layer, a secondary coat layer and a protective layer in sequence, and the undercoat layer is copolymerized by carbon dioxide 80 parts of polyols, 18 parts of diisocyanates, 22 parts of chain-extending cross-linking agents and 14 parts of hydrophilic chain-extending agents; 7 parts of sustained-release microcapsules, 16 parts of ethyl acetate, 0.3 parts of white mineral oil and 10 parts of dye; the protective layer is made of 27 parts of hydroxyethyl cellulose ether, 2 parts of sodium lauryl sulfate, polypropylene Made from 4 parts of amide and 6 parts of triethanolamine; this kind of high-transmittance fiber glass paper can significantly improve the light transmission and surface smoothness of the fiber, and the surface smoothness of the paper after double-sided treatment is greater than 210 seconds, and at the same time The preparation method of the process is simple and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a high light transmission fiber glass paper with strong light transmission and high surface smoothness and a preparation method thereof. Background technique [0002] At present, sulfuric acid paper (also known as tracing paper) is the only paper with light-transmitting properties on the market, which is mainly used in tracing, transfer printing and limited printing. Sulfuric acid paper is made of fine plant fibers interwoven with each other. After free beating, no sizing, no filler, and papermaking process in a wet state, it is soaked in concentrated sulfuric acid with a concentration of 72% for 2 to 3 seconds. Film-type paper formed after washing, glycerin treatment, and drying. The sulfuric acid paper prepared by this method is solid, dense and translucent, but its surface is very rough and has poor flatness, and the smoothness is generally less than 9...
