Wall coating with energy-saving effect for museum decoration and preparation method thereof

Abstract

The invention relates to a preparation method of a coating, and particularly relates to a wall coating with an energy-saving effect for museum decoration. The coating sequentially comprises a base layer, a foam layer and a sealing layer from inside to outside, wherein the base layer contains active hydroxyl; the foam layer contains groups capable of reacting with the active hydroxyl, and can foam and expand at a temperature of more than 10 DEG C to form dense small pores; and the sealing layer can cover the small pores on the surface of the foam layer, and can be bonded with the foam layer. The wall coating overcomes the defect of high energy consumption caused by high heat conduction efficiency of a wall in a museum in the prior art. The coating has good heat preservation and insulation effects through a multi-layer structure, effectively reduces the energy consumption, and has good mechanical properties, thereby having the advantage of long service life. In addition, the wall coating has good sound insulation and absorption effects, and can absorb noise in the museum.

Description

technical field [0001] The invention relates to a coating preparation method, in particular to a museum decorative wall coating with energy-saving effect and a preparation method thereof. Background technique [0002] A museum is a place for collection, collection, display and research of physical objects representing natural and human cultural heritage, as well as a cultural and educational institution, building, location or social public institution that classifies and manages collections and provides knowledge, education and appreciation for the public . Inside the museum, due to the need to prevent the collections in the museum from being damaged by the environment, the environment in the museum needs to maintain constant temperature and humidity conditions. In order to achieve constant temperature conditions, it is necessary to turn on the air conditioner 24 hours a day. However, conventional museum walls are usually made of concrete with high heat transfer efficiency,...
