Description
Technical Field
The utility model relates to a sun-shading composite material with a formaldehyde removing function, and belongs to the field of building decoration materials.
Background
With the improvement of living standard of people, home decoration of common people is gradually advanced, and the updating of furniture and soft decoration products tends to be more frequent. During this period, if the interior is over-decorated or the building materials (such as paint, plate material and glue) are not properly selected, Volatile Organic Compounds (VOC) pollutants are generated in the interior environment, which is one of the main factors affecting human health. Among them, formaldehyde is one of the most representative substances in indoor pollutants, and too high concentration of formaldehyde can cause great harm to human body, causing symptoms such as dyspnea, severe headache, and sore throat. Therefore, effectively reducing or controlling the concentration of formaldehyde in the room is an effective means for guaranteeing the health of the human body.
The formaldehyde gas has serious threat to the health of people, and various policies for strictly limiting the emission of the formaldehyde gas are issued in China, so that the health of people is better protected. For example, in GB 18401-. The adoption of a scientific and efficient method for removing indoor residual formaldehyde is urgent, and in the existing formaldehyde removing method, besides the adoption of building material source control, ventilation and air exchange and plant biological purification, an adsorption method and a photocatalytic oxidation method are also emphasized, so that the method is deeply researched in the aspect of improvement of the air quality of a room.
The adsorption method is to perform physical adsorption by utilizing the characteristic that an adsorption medium has a developed pore structure, and common porous adsorbents comprise activated carbon, zeolite molecular sieves, attapulgite and the like. The raw material sources of the adsorbents are wide, the preparation is simple, but each adsorbent has an adsorption limit value when in use, namely the adsorbent cannot adsorb formaldehyde molecules on a pore structure of the adsorbent, and secondary pollution can be caused after the formaldehyde molecules break away, so that the formaldehyde removal efficiency is reduced. Therefore, how to effectively eliminate the adsorbed formaldehyde molecules is a key problem for improving the purification effect of the adsorbents. The photocatalytic oxidation method is that under the irradiation of light with certain wavelength, electrons are excited by energy to make formaldehyde produce reactionOxidized to form water and carbon dioxide, in which the catalyst is nano TiO2The application is more. Nano TiO 22Under the condition of illumination, oxygen and water molecules on the surface of the material are activated by a hole-electron pair to generate active free radicals and active oxygen, and formaldehyde can be decomposed. Unmodified nano TiO2Due to the defects of the photocatalyst, the visible light utilization rate is low and the photocatalytic efficiency is not high; using metal ions (e.g. Fe)3+、Zn2+Etc.) with nano TiO2After doping, the crystal lattice structure of the material can be changed, the photocatalytic capability is promoted to be improved, and the formaldehyde can be oxidized and decomposed within the visible light range.
Therefore, the sun-shading composite material with the formaldehyde removing function can be designed, and the curtain processed by the composite material can not only shade the sun, but also remove the formaldehyde in the environment and improve the indoor air environment by an adsorption method and a photocatalytic oxidation method. Therefore, the method has positive significance in exploring how to combine and apply the two methods to prepare the sunshade composite material.
