Abstract

The invention relates to a preparation method for a humidity adjusting fiberboard, which comprises the following steps: A), mixing sodium carboxymethyl cellulose, sodium polyacrylate, diatomaceous earth, glycol glycidyl ether and deionized water, adding hollow fibers and continuously mixing well; B), pressing the mixture prepared in A) into a sheet and drying the sheet; and C), placing the dried fiberboard in salt solution of a certain concentration, immersing the fiberboard for a certain period, and drying the fiberboard to obtain the humidity adjusting fiberboard. Compared with the existinghumidity adjusting plate, the invention has the following advantages that: 1), the humidity adjusting fiberboard has high speed of response to humidity and high moisture content; 2) humidity adjusting fiberboards with different target levels of humidity can be prepared according to different proportions of inorganic salts; 3) the preparation is simple, the cost is low and the effect is good; 4) the humidity adjusting fiberboard is non-toxic, harmless and non-polluting for the environment and complies with development trends of environmental protection; and 5) the functions of automatic humidity adjustment and thermal insulation can be achieved at the same time.

Description

technical field [0001] The invention relates to a preparation method of a fiberboard material, in particular to a preparation method of a humidity-adjusting fiberboard. Background technique [0002] As an ancient civilization with thousands of years of history, my country has a wide variety of cultural relics, rich in quantity and long in history, so they have very important historical, artistic and scientific values. However, many cultural relics have suffered varying degrees of damage and damage due to the influence of the micro-environment after they were unearthed. Among them, there are many precious cultural relics that are priceless and cannot be copied. Once damaged, they cannot be restored. [0003] The main environmental factors affecting cultural relics are temperature, humidity, light, air pollution, microorganisms, etc. Among them, humidity is a very important quality index in the environmental quality of museums. Both metals (except copper, iron, and gold) and ...
