Description

Dual-channel formaldehyde-removing sun-shading composite material
Technical Field
The invention relates to the technical field of building decoration materials, in particular to a two-channel formaldehyde-removing sun-shading composite material.
Background
Formaldehyde is one of the most representative substances in indoor pollutants, and if the interior is over-decorated or building materials (such as paint, plates, glue and the like) are not properly selected, heavy decoration pollution can be caused, including the generation of excessively high concentration of formaldehyde. Such contamination can be extremely harmful to humans, causing the human to experience symptoms such as dyspnea, severe headache, burning throat, etc. 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 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, diatom ooze, attapulgite and the like. The raw material sources of the adsorbent are wide, but the adsorbent can not adsorb formaldehyde molecules on a pore structure of the adsorbent because of the maximum adsorption value of each adsorbent in use, 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 characterized in that electrons of a photocatalyst are excited by energy under the irradiation of light with certain wavelength, so that formaldehyde is oxidized to generate water and carbon dioxide, the catalyst can only digest smaller surrounding formaldehyde, and the active digestion effect on formaldehyde at other indoor positions is not achieved; therefore, the design and preparation of new materials with high formaldehyde removal function are very important.
The sunshade composite material is a fiber-based building decoration material which is processed by adopting chemical fiber filaments as a base material and adopting double-layer tissue weaving or coating finishing. Along with the improvement of living standard of people, the quality of the sun-shading composite material is required to be higher, the content of formaldehyde released by the sun-shading composite material is required to be lower, and the sun-shading composite material has a certain formaldehyde removing effect in use. In view of this, a sun-shading composite material with formaldehyde removing function can be designed, which not only can shade the sun, but also has a composite dual-channel formaldehyde removing function, for example, formaldehyde can be removed through adsorption and photocatalyst oxidation (i.e. formaldehyde in the environment is enriched by virtue of the adsorbent, and then the adsorbed formaldehyde is removed through catalytic oxidation under the illumination condition), and formaldehyde can also be removed through adsorption and capture agent digestion (i.e. formaldehyde capture agent can react with the formaldehyde enriched by the adsorbent, so as to achieve the digestion of formaldehyde in the environment); the design and preparation of the sunshade composite material with the dual-channel formaldehyde removal function have positive application value and potential market prospect.
