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 a photocatalysis composite material having performances of regulating temperature and moisture as well as a preparation method thereof, which belong to the technical field of a functional material and building energy efficiency. The composite material contains a phase-change material and a photocatalysis material, the phase-change material is a mixture of palmityl alcohol, palmitic acid and lauric acid; and the photocatalysis material is Eu-Ce / TiO2. The preparation method comprises three steps: 1) preparing palmityl alcohol-palmitic acid-lauric acid mixture as the phase-change material, 2) preparing the Eu-Ce / TiO2photocatalysis material, and 3) preparing the photocatalysis composite material having the performances of regulating temperature and moisture. The photocatalysis composite material having the performances of regulating temperature and moisture is capable of performing photocatalytic degradation on formaldehyde gas under visible light source and adjusting indoor temperature and humidity, is effectively enhancing the comfort level of indoor environment and improving indoor air quality, reduces building energy consumption, and accords with a development tendency of a national green ecological building material.

Description

technical field [0001] The invention belongs to the technical field of functional materials and building energy conservation, and in particular relates to a photocatalytic composite material with temperature-regulating and humidity-regulating performance 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...
