Preparation method of museum environmental-protection humidifying agent

Abstract

The invention discloses a preparation method of a museum environmental-protection humidifying agent, which adopts the following steps of A) adding konjac glucomannan and sodium carboxymethylcellulose in water to be blended and gelatinized; B) adding products of the step A) in crylic acid, sodium hydroxide, initiator and a cross-linking agent, adjusting the temperature to be at 55DEG C to 60 DEG C to react for 1-2h, and stoving the reaction products by using microwaves; and C) grinding stoved sample in the step B), sieving by using a 20-mesh sieve and a 40-mesh sieve, obtaining 20-40 mesh particles to add in buffered solution with the pH of 4-6, preheating for 5-10min in a water bath at the temperature of 50-60 DEG C, adding glucanase in certain proportion, conducting enzymolysis for 0.5-2h, boiling for 10min at the temperature of 100 DEG C for oxyreductase, conducting suction filtration on obtained products, and conducting microwave drying to obtain the museum environmental-protection humidifying agent. Dosage of the buffered solution is 20-30 times of that of the sample, and the dosage of glucanase is 0.5-2% of that of the sample. The preparation method is rapid in product humidity response, big in humidity ratio, simple in manufacture cost and convenient to manufacture.

Description

technical field [0001] The invention belongs to the technical field of humidity control materials, in particular to a preparation method of an environment-friendly humidity control agent for museums. Background technique [0002] Cultural relics are relics and relics left by human beings in the process of historical development. All kinds of cultural relics reflect from different aspects the social activities, social relations, and ideological relics of human beings in various historical periods, using nature, transforming nature, and the status of the ecological environment at that time. They are precious historical and cultural heritage of mankind. The protection, management and scientific research of cultural relics are of great significance for people to understand their own history and creative power, reveal the objective laws of human social development, and understand and promote the development of contemporary and future societies. Therefore, how to control the coll...

Problems solved by technology

[0004] At present, air-conditioning technology is mainly used to control the humidity of collections and exhibition environments. However, air-conditioning technology consumes a lot of energy, is not environmentally friendly, and can easily cause "air-conditioning syndrome" in workers. Therefore, how to prepare humidity-adjusting materials is very important for adjusting the museum environment. of great significance
