Abstract

The invention discloses a wall humidifying material and a preparation method thereof. The wall humidifying material comprises the following components in parts by weight: 1-5 parts of wool fiber, 2-5 parts of jute fiber, 50-54 parts of sand, 15-19 parts of standard cement, 1-185 parts of pulverized fuel ash, 1-5 parts of hydraulic lime, 1-13 parts of additive and water, the parts by weight of which are 0.99-1.2 times of the total parts by weight of the wool fiber, the jute fiber, the sand, the standard cement, the pulverized fuel ash, the hydraulic lime and the additive. The preparation method comprises the following steps: uniformly mixing the wool fiber, the jute fiber, the sand, the standard cement, the pulverized fuel ash, the hydraulic lime and the additive, then adding water, and uniformly stirring so as to obtain the wall humidifying material. The wall humidifying material has high hygroscopic capacity, tensile performance and shrinkage resistance. When being applied to the inner surfaces of buildings, the wall humidifying material is capable of preventing wall cracking, adjusting indoor humid environments and reducing the energy consumption of air conditioner systems.

Description

Technical field [0001] The present invention is the field of preparation technology of composite materials, involving a wet material and preparation method based on wool and jute. Background technique [0002] Many regions in my country are humid in summer and dry winter. For example, North China, East China, and the eastern parts of the Yangtze River Basin are even more humid year by year. EssenceIn order to improve the comfort of the building environment in these areas, active humidity control technology is currently adopted. For example, in summer, freezing dehumidification, rotor dehumidification or solution dehumidification, and ultrasonic humidification is used in winter.These technical means can effectively improve the comfort of the building environment, but also consume a lot of energy.Passive and humidifying techniques are used in dry areas in dry and winter in summer. The moisture adjustment materials can be absorbed in summer, reducing indoor humidity, and humidifying...
