Problems solved by technology

Improper temperature and humidity control will bring disasters to cultural relics: cultural relics containing organic matter will reproduce microorganisms due to high relative humidity, leaving stains, and even mildew; if the relative temperature is too low, wood, ancient ink, etc. will crack and become brittle; The alternating change of relative humidity is more harmful, which will accelerate the fatigue of materials and aggravate deformation, even pottery and stone carvings are hard to escape

Abstract

The invention relates to a preparation method of microenvironment conditioned paper of a museum, which is characterized by comprising the following steps: (A) adding sepiolite, decalso, isinglass and urea into deionized water, stirring and reacting for 4-6h at 50-60 DEG C; (B) adding cyclic acid, polyethylene glycol, ammonium persulfate and the deionized water into reactant of the (A), stirring and reacting for 3-5h at 50-60 DEG C; (C) cooling mixture obtained by the (B) to be room temperature, drying to obtain temperature and humidity adjustment material; (D) adding the temperature and humidity adjustment material and magnesium sulfate into paper pulp for manufacturing paper to prepare the microenvironment conditioned paper of the museum. Compared with the conditioned paper, the invention has rapid humidity adjustment response, low material phase-transition temperature, high humidity content, rapid heat absorption, good balance of humidity maintenance, simple and convenient manufacture, low cost, good effect, no toxicity, harm or pollution to the environment, and the like, and accords with the trend of the environment protection development.

Description

technical field [0001] The invention relates to a preparation method of a textile fiber material, in particular to a preparation method of a museum microenvironment humidity-regulating paper. Background technique [0002] my country is an ancient civilization with a history of thousands of years. There are many kinds of cultural relics, and the quantity is extremely rich. However, with the passage of time, these cultural relics are being damaged and damaged to varying degrees. Among them, there are many precious cultural relics that cannot be copied. , once damaged it cannot be recovered. [0003] Studies have shown that the main environmental factors affecting cultural relics are: temperature, humidity, light, air pollutants, microorganisms, etc., among which temperature and humidity are the two most basic conditions. They influence and interact with each other, directly affect and even determine all physical, chemical and biological functions of cultural relics. Therefore...
