Abstract

The invention provides a preparation method of high-efficiency compound humidity-controlling paperboard, comprising the following steps: a-f, preparing humidity-controlling resin per se for later use; g, adding 0.1 part of sodium carboxymethylcellulose into 5 parts by weight of water, stirring till the sodium carboxymethylcellulose is evenly dispersed in the water, and stewing to enable the sodium carboxymethylcellulose and the water to be infiltrated and fused with each other to form into pasty glue solution for later use; h, adding 0.5 part by weight of kieselguhr, 2.5 parts by weight of L-pyrrolidone carboxylic acid-Na, 0.3 part by weight of sodium chloride and 2.7 parts by weight of anhydrous potassium carbonate into 100 parts by weight of water, and stirring to be dissolved; i, taking 4.25 parts by weight of dry paper pulp, adding the paper pulp and the pasty glue solution obtained in step g into mixed solution obtained in step h, and pulping for 2min; j, adding 1.7 parts by weight of the humidity-controlling resin obtained in step f into the mixture obtained in step i, and stirring by a stirrer; and k, papermaking, and drying under the temperate of 80-100 DEG C for 5-7h. The paperboard is very convenient to regenerate and reuse; and the preparation method is simple in production technology and equipment, and easy to industrialize.

Description

technical field [0001] The invention relates to a preparation method of a high-efficiency composite humidity-adjusting paperboard, which is mainly suitable for humidity adjustment of cultural relic preservation environments. Background technique [0002] Humidity regulation methods are mainly divided into active humidity regulation and passive humidity regulation methods. Active humidity control mainly relies on mechanical adjustment, such as dehumidifiers, humidifiers, and constant humidity air conditioners. This method often consumes a lot of energy, occupies a large area, requires personnel maintenance, and directly or indirectly causes air pollution (greenhouses) effect), heat pollution, etc.; passive humidity control materials refer to materials that do not need any artificial energy and mechanical equipment, rely on their own moisture absorption and desorption characteristics to sense the humidity changes in the surrounding environment, and reduce the higher space humi...
