In order to better prevent the aging of the masking paper, the masking paper is characterized in that the reflection film comprises an infrared reflection film and an ultraviolet reflection film, the infrared reflection film comprises metal oxide, the metal oxide is zinc oxide and tin oxide, the ultraviolet reflection film comprises a high-refraction layer medium material layer and a low-refraction layer medium material layer, and the high-refraction layer medium material layer and the low-refraction layer medium material layer are both silicon nitride.
In order to prevent excessive moisture from accelerating aging of the textured paper, the water absorption film is characterized by comprising polyacrylic acid and polyvinyl alcohol.
The working principle of the invention is as follows: the causes of paper aging include internal causes including the possibility that the main components of paper structurally age, and external causes. The main chemical components of paper are cellulose, hemicellulose and lignin, and there is a possibility of aging on their respective structures. Wherein cellulose is the most important chemical component in paper, and aging possibility exists in the molecular structure of cellulose and the structure of cellulose, because the glucose group of the structural unit of cellulose is connected by 1-413 glycosidic bonds, which can be hydrolyzed and catalyzed by acid, enzyme and the like;
meanwhile, each glucosyl group in the cellulose molecule has three naked hydroxyls which can generate oxidation reaction, and the hydroxyls can cause the further chain scission of the cellulose molecule after being oxidized;
further, the C-C bond and C-0 bond in the cellulose molecule can be broken by the action of ultraviolet rays, thereby lowering the polymerization degree of the molecule.
Moreover, since the amorphous region exists in the fiber, external adverse factors easily invade into the fiber to accelerate the aging of the fiber.
Hemicellulose and lignin are easy to oxidize and generate colored structural genes after oxidation, so that paper is yellowed. In addition, UV can also break C-C bonds and C-0 bonds in lignin molecules.
In addition, harmful substances that promote the aging of paper are present inside the paper. These harmful substances are mainly carried in the paper production process and mainly comprise: acid or alkali remained in the pulping process, oxidant remained in the bleaching process, and orange-fragrant glue and precipitated alum added in the sizing process.
External causes include light, acidity, oxidizing agents, temperature, moisture, and other factors. Wherein the light includes ultraviolet rays and infrared rays, and the ultraviolet rays can directly cause photolysis of molecules such as cellulose. The primary light that causes paper aging is ultraviolet light. Ultraviolet light can break C-C bonds and C-O bonds if the C-C bonds and C-O bonds are in the main chain, the ultraviolet light can break the main chain of the molecule, thereby reducing the degree of polymerization of the molecule. Cellulose molecules, hemicellulose molecules and cellulose molecular structures all have C-C bonds and C-O bonds, so that all the structures can generate photolysis, and ultraviolet rays can cause photosensitive degradation of substances such as cellulose and the like and have photooxidation destruction;
the paper can absorb the energy of the infrared rays after being irradiated by the infrared rays and then is changed into heat energy, so that the temperature of the paper is increased, the internal reaction speed is accelerated, the aging of the paper is accelerated, and therefore, the aging of the paper can be influenced by the rays in various aspects, and therefore, the reflecting film is added in the paper.
Furthermore, the cellulose has a molecular structure with a large number of oxygen bridges (one O-is 1-4, S glycoside bond), which has a characteristic that the cellulose is easy to be broken in the presence of acid, and is hydrolyzed into hydrolyzed cellulose after being broken, the oxygen atom in the original oxygen bridge has a negatively charged electron pair (one O-), firstly attracts the H ion ionized from the acid to be changed into a form, because one U-of H affects the breakage of the oxygen bridge, the polymerization degree of the cellulose molecule is reduced, the hydroxyl group and recessive aldehyde group are increased, and if the cellulose is completely hydrolyzed, the glucose molecule is finally generated. Because the harm of acid is great and the source of acid is manifold, the acid prevention and removal cannot be ignored.
The effect of moisture on the aging of textured paper is reflected in: the cellulose in the fiber has an amorphous area, most of hydroxyl groups on cellulose molecules in the amorphous area do not form hydrogen bonds, the hydroxyl groups have polarity, and water molecules also have polarity, so that the hydroxyl groups can attract the water molecules to form the hydrogen bonds, and capillary pores in the fiber structure of the paper can also adsorb the water molecules. Besides cellulose, the fiber also contains hemicellulose, and hemicellulose molecules also contain a large number of hydroxyl groups, and hydrogen bonds are difficult to form among the molecules, so the hemicellulose molecules can absorb moisture. In addition, lignin molecules are also hygroscopic. Moisture accelerates paper aging and is mainly characterized by the following aspects:
(1) After the cellulose absorbs water, necessary conditions are provided for hydrolysis of cellulose and hemicellulose molecules, and the oxidative degradation of the cellulose and hemicellulose molecules can be accelerated by the wet paper.
(2) The paper is easy to grow mildew after being wetted, and the aging of the paper can be promoted by enzyme secreted by the mildew and organic acid generated by decomposing organic matters.
(3) Paper moisture accelerates the destruction of the paper by other harmful substances. For example, the acid harmful gas is easily absorbed by the paper to generate acid, and in addition, alum in the paper is more easily hydrolyzed to generate sulfuric acid.
(4) The capillary pores in the paper sheet absorb water to increase the distance between fibers, so that harmful substances are easy to invade.
Thus adding a water-absorbing film.
Has the advantages that:
compared with the prior art, the invention adds the water absorption film, the ultraviolet reflection film and the infrared reflection film, and adds the alkaline neutralizer into the sizing agent of the crepe base paper to neutralize the acidity brought by paper in the modern papermaking process.
The method takes the factors of acidity, ultraviolet rays, infrared rays and moisture into consideration that the aging of the paper is mostly caused, so that the prevention measures are added, the anti-aging effect is achieved, and the service life of the textured paper is prolonged.
