Problems solved by technology

Because these technologies only consider the influence of micropores on the humidity control performance of materials, and ignore the control of macropores, the moisture absorption and desorption performance is poor, and the humidity of the indoor environment cannot be effectively controlled.
At the same time, most of the above technologies use natural polymers or inorganic minerals as raw materials, with low waste rate and high production cost, which is not conducive to the sustainable development of circular economy and ecological environment

Abstract

The invention relates to a temperature-sensitive humidity-sensitive functional building material and a preparation method thereof. The functional building material is a plate made from the following ingredients in parts by weight: 40-60 parts of cementing material, 6-12 parts of composite temperature control material, 15-30 parts of semi-carbonized plant fiber, 10-25 parts of filling, 0.5-2 parts of foaming agent, and 0.05-0.2 parts of foam stabilizer. The preparation method comprises the following steps of: uniformly mixing all the ingredients, adjusting the ratio of water to materials to 0.30-0.45 to prepare the plate, curing the plate in an environment at the temperature of 25 DEG C and relative humidity not less than 80% for 7 days and then drying the plate to obtain the temperature-sensitive humidity-sensitive functional building material. Therefore, the temperature-sensitive humidity-sensitive functional building material provided by the invention can be used for effectively improving the comfort of an indoor environment, is simple in production and construction process, can be widely applied to the inner walls of an existing building and a new building, and is of a great significance in energy conservation, emission reduction and circular economy development.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a temperature-sensitive and moisture-sensitive building functional material and a preparation method thereof. Background technique [0002] At present, 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. According to estimates, by 2020, the proportion of my country's building energy consumption to the total energy consumption of the whole society will rise to 35%, and the peak load of air-conditioning power in the country will quadruple, reaching the full-load power equivalent to about 10 Three Gorges Power Stations. The use of new high-performance, functional, intelligent, and ecological materials to improve building safety, light weight, high strength, and durability is considered to be the main way to save energy in building...
