Problems solved by technology

Because these technologies use inorganic porous materials as humidity control components, the moisture absorption and desorption effects are poor, the humidity control effect is not significant, and they do not contain temperature control components, so they cannot effectively control indoor humidity and temperature.
In addition, the raw materials are all natural polymers or inorganic minerals, which do not meet the requirements of energy conservation, emission reduction and sustainable development strategies

Abstract

The invention belongs to the field of a building material and particularly relates to an environment-friendly passive type temperature controlling and humidifying material and a preparation method thereof. The environment-friendly passive type temperature controlling and humidifying material comprises the following components in parts by weight: 50-70 parts of gypsum, 5-10 parts of modified bentonite, 10-25 parts of a humidifying agent, 5-15 parts of cement and 3-8 parts of carbide slag. The components are uniformly mixed and sealed to obtain the temperature controlling and humidifying material. The environment-friendly passive type temperature controlling and humidifying material disclosed by the invention is good in temperature controlling effect, excellent in humidifying performance and simple in production and construction process, can be widely applied to inner walls of an existing building and a newly-built building, and has very important meaning to the development of energy conservation and emission reduction as well as circular economy.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an environment-friendly passive temperature-controlling-humidity-regulating material and a preparation method thereof. Background technique [0002] The comfort of the building's indoor environment has always been a hot spot that people pursue and research. As one of the important factors that affect the comfort of the living environment, air humidity and temperature directly affect people's physical and mental health and the preservation of various items. At present, air-conditioning technology is widely used to adjust indoor humidity and temperature, but it consumes a lot of electricity. It is reported that about 1 / 3 of the world's total energy consumption is building energy consumption, of which heating and air conditioning energy consumption account for 60% to 70% of building energy consumption. . The development of suitable high-performance temperature-controll...
