Problems solved by technology

However, relying on artificial heating, cooling, humidification and other equipment can provide a more comfortable indoor environment, but it needs to consume a lot of energy, and the equipment needs to limit the natural ventilation conditions of the indoor environment during use, which is easy to cause "indoor syndrome". "disease; in addition, it is difficult to effectively clean the pipeline during the operation of the equipment, and it is easy to cause microbial growth after long-term use, resulting in secondary pollution of the indoor environment

Abstract

The invention discloses an interior wall coating having multiple functions of temperature and humidity regulation and photocatalysis and a preparation method thereof and belongs to the technical field of photocatalytic coatings and building energy saving. The coating is prepared from a photocatalytic packing, a temperature and humidity regulating packing, a film-forming material, a dispersing agent, a stabilizing agent, a wetting agent, a mildew preventive, a defoaming agent, a flatting agent, a thickener, a drier, a drying assistant, water and the like, wherein the photocatalytic packing is Eu-Ce / TiO2, and the temperature and humidity regulating packing is a SiO2 based hexadecanol-palmitic acid-lauric acid microcapsule temperature and humidity regulation material. The preparation method of the coating comprises the steps of (1) preparation of the photocatalytic packing, (2) preparation of the temperature and humidity regulating packing and (3) preparation of the interior wall coating having the multiple functions of temperature and humidity regulation and photocatalysis. The coating can conduct photocatalytic degradation on formaldehyde gas and regulate indoor temperature and humidity in the presence of a visible light source, effectively improves the indoor environment comfort and the quality of indoor air, reduces building energy consumption and conforms to the development trend of national green ecological building materials.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic paint and building energy saving, and in particular relates to a multifunctional interior wall paint with temperature regulation, humidity regulation and photocatalysis and a preparation method thereof. Background technique [0002] The indoor environment is a space where 80% of the time of life is active, and its comfort is very important. For a long time, in order to meet people's requirements for the comfort of the indoor environment, a large number of decorative materials and various active methods have been used, such as: wood-based panels to create a beautiful indoor environment. Spaces, heating and cooling equipment to regulate indoor temperature, humidifiers to control indoor humidity, etc. However, relying on artificial heating, cooling, humidification and other equipment can provide a more comfortable indoor environment, but it needs to consume a lot of energy, and the equipment n...
