Delivery particle and application thereof

Abstract

The invention relates to the technical field of humidity adjusting materials. A delivery particle is disclosed. The respective humidifying advantages of a porous material, a high polymer material andan inorganic salt are integrated; by introducing a foaming agent, the combination of a moisture absorption and desorption medium, a moisture storage source and a moisture storage space is achieved; the composite humidifying material with excellent humidifying performance is synthesized, then the mildew-proof antibacterial material is added, so that the composite humidifying particles with the particle size of 0.5-3.5 mm and the humidifying and mildew-proof antibacterial functions are prepared; therefore, the contact area between the humidifying material and air is increased, the humidifying material and a conventional building material can be fused, and diversified application of the humidifying material is achieved.

Description

technical field [0001] The invention relates to a humidity control material, which has better effects especially on the control of relative humidity in building rooms. The composite humidity-regulating particles can control the relative humidity of a relatively closed space with a certain volume within a certain range. Background technique [0002] The indoor environment of a building refers to the sum of all factors related to the building and polymorphic. The building indoor environment involving resources and energy consumption is mainly the building physical environment, which includes heat, humidity environment, light environment, acoustic environment and indoor air quality. At present, the research on indoor thermal environment has achieved fruitful results. In contrast, little research has been done on indoor wet environments. [0003] However, the building wet environment is a key factor affecting human thermal comfort, human health, storage of goods, durability o...
