Problems solved by technology

For example, in the humidifier, aluminum foil humidification wet curtains made of aluminum foil have appeared on the market. The wet curtain adopts the water pouring method from top to bottom. Humidification and cooling effects on the environment; however, due to the composition of the aluminum foil itself, it lacks the retention and adsorption of water vapor, and it lacks the regulating effect on water and water vapor, and the water absorption is insufficient, resulting in a small amount of humidification

Abstract

The invention discloses a preparation method of a novel water-absorbing antibacterial stent composite humidifying material, which comprises the following steps: performing dip-coating or spray-coating on a water-absorbing material through functional slurry prepared by mixing a water-based emulsion, a bactericide and deionized water, drying with hot air, and compounding with a porous support net to obtain the novel water-absorbing antibacterial stent composite humidifying material. After the water-absorbing material prepared from the functional slurry is compounded with the porous supporting net, the water-absorbing material is endowed with excellent antibacterial performance, the killing rate of common bacteria such as tritirachium, bacilli and staphylococcus can exceed 99%, and meanwhile, the moisture absorption performance of the raw materials is not influenced. The air permeability of the product is improved due to the porous supporting net, so that the humidification amount is increased, and the humidifying module is not prone to deformation, wide in application range, long in service life, easy to machine and capable of being manufactured into various shapes such as a corrugated type, a folded type, a punching net pulling type and a winding type.

Description

technical field [0001] The invention relates to the technical field of air humidification and humidity control, in particular to a novel water-absorbing antibacterial bracket composite humidification material and a preparation method thereof. Background technique [0002] With the improvement of people's requirements for air quality, environmental humidity control has become a necessary condition for indoor comfortable environment. Common humidification and humidity control materials are mostly found in hygroscopic paper, hygroscopic spunlace cotton, hygroscopic polymer membrane materials and other materials, but these materials have disadvantages such as easy contamination by bacteria, short service life, and easy structure collapse. Metal and plastic materials have also become a choice in the industry, among which metal aluminum foil and copper foil have become the preferred material categories in the industry due to their high ductility and workability. For example, in t...
