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 alternation of relative humidity is more harmful, which will accelerate material fatigue and aggravate deformation, even pottery and stone carvings are hard to escape

Abstract

The invention relates to a method for preparing a temperature-adjusting humidity-adjusting material, which is characterized by adopting the following steps: (A) adding activated meerschaum, artificial zeolite, gelatin and urea into deionized water sequentially and stirring to react for 4-6h at the temperature of 50-60 DEG C; (B) adding acrylic acid, polyethylene glycol, ammonium persulphate and the deionized water into a reactant in the step (A) sequentially and stirring for 3-5h at 50-60 DEG C; and (C) cooling a mixture formed in the step (B) to room temperature, forming viscous liquid, drying at the temperature of 80-90 DEG C and preparing the temperature-adjusting humidity-adjusting material. Compared with the prior humidity-adjusting material, the invention has the following outstanding advantages of quick response of the temperature and the humidity, low phase change temperature of the material, high moisture content, quick heat absorption, good kept balance of the temperature and the humidity, and the like.

Description

technical field [0001] The invention relates to an environmental material, in particular to a preparation method of a temperature-regulating and humidity-regulating material. 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 factors. They influence and interact with each other and directly affect the protection effect of cultural relics. Therefore, it is extremely important to preserve cultural relics in a s...
