Abstract

The invention discloses a wall material capable of adjusting indoor environmental temperature and humidity and a preparation method of the wall material. The wall material is prepared from components in percentage by weight as follows: 42%-52% of building plaster, 5%-15% of temperature adjustment components, 2%-8% of humidity control components, 32%-42% of water, 0.1%-0.4% of water reducing agents, 0.005%-0.01% of pigments and 0.2%-1.0% of fiber. According to the wall material, the preparation process of a functional wall material is optimized, fluctuation of indoor environmental temperature and humidity is reduced, the durability, the anti-permeability, the anti-cracking performance and the fireproof performance of a wall body are improved, and energy consumption is reduced during construction; with the adoption of the temperature adjustment components and the humidity control components, the wall material has the function of indoor environmental temperature and humidity adjustment, the homogeneity of the wall material is guaranteed, and a product has high strength and seldom contracts; the thermal physical performance of the wall material is excellent, the wall body does not require a thermal-insulation layer, and construction procedures are reduced.

Description

technical field [0001] The invention relates to the field of construction, in particular to a wall material capable of adjusting indoor environment temperature and humidity and a preparation method thereof. Background technique [0002] At present, the country's requirements for building energy conservation are increasing day by day, and people's requirements for the comfort of the living environment are also getting higher and higher. Therefore, there is an urgent need for a new material that can regulate indoor temperature and humidity and effectively reduce building energy consumption. . The rapid development of phase change energy storage technology and hygroscopic materials provides the possibility for the development of this material. At present, phase change energy storage materials have been applied in the fields of solar energy utilization, waste heat utilization, and building energy conservation. [0003] The temperature adjustment ability of traditional wall mat...
