Abstract

The patent refers to the field of 'special paper'. The invention relates to a method for preparing high-efficiency composite humidifying paper. The method is characterized in that: a copolymerization reaction of sodium polyacrylate, carboxymethylcellulose, sepiolite, acrylamide and paper pulp is performed so as to obtain composite paper pulp, and the composite paper pulp is subjected to papermaking to form paper. Compared with the prior art, the method has the advantages that 1) the moisture content of the humidifying paper is high, and the humidifying rate is quick; 2) the relative humidity of microenvironment can be regulated to be between 50 and 60 percent within short time, and is maintained within the humidity range for a long time; 3) the preparation method is simple, the cost is low, paper materials are light, and application modes are diversified; and 4) compared with that of raw paper, the bursting strength of the composite humidifying paper is increased by over 50 percent.

Description

technical field [0001] The invention relates to a polymer functional material, in particular to a preparation method of high-efficiency composite humidity-conditioning paper. Background technique [0002] Energy-saving, environmentally friendly, and green ecological smart materials are attracting more and more attention. Among them, the research on humidity-controlling functional materials has gradually shifted from the research of traditional inorganic salts, silica gel, and inorganic minerals to the research of porous resins, organic-inorganic composites, and biomass materials. Mainly using the porous structure of inorganic minerals and the high moisture content of organic polymers, as well as the large amount of moisture-absorbing guiding groups in biomass, studies have proved that cellulose-based materials have better moisture-regulating properties than sodium acrylate and perlite, and porous minerals can Effectively use its own porous structure to absorb and dehumidify....
