Human’s daily life and production activities will produce harmful particles. These substances are scattered in the air or water and have a serious impact on human health and normal production and life. Dust and smoke will damage the working environment and affect human health. The mixing of dust and smoke will reduce the service life of the instrument and reduce the quality of industrial raw materials. With the development of China's economy, environmental pollution has been put on the agenda, and China has become one of the fastest
growing and largest filter material markets in the world. Filtration is an operation that separates and traps particulate matter dispersed in gas and liquid. However, there is still a lack of air filter materials with high temperature resistance and mildew resistance in the market to meet people's needs. Content of the utility model The purpose of the present utility model is to provide an air filter material resistant to high temperature and mildew, so as to solve the problems raised in the background art. In order to achieve the above objectives, the present invention provides the following technical solutions: a high-temperature and mildew-resistant air filter material, including a non-woven fabric protective layer, an aromatic polyamide fiber layer, a honeycomb activated carbon filter layer, an ultra-fine glass fiber layer and Anti-mold composition layer, the non-woven fabric protective layer is arranged on the outermost layer of the entire air filter material, the inside of the non-woven fabric protective layer is provided with an aromatic polyamide fiber layer, and the honeycomb activated carbon filter layer is wrapped Inside the aromatic polyamide fiber layer, an ultra-fine glass fiber layer is arranged inside the aromatic polyamide fiber layer, and the anti-mold composition layer is wrapped inside the ultra-fine glass fiber layer. 'Preferably, the diameter of the filter particles of the non-woven protective layer is larger than the diameter of the filter particles of the ultrafine glass fiber layer. 'Preferably, the thickness of the honeycomb activated carbon filter layer is 0.3 mm. 'Preferably, the anti-mold composition layer is composed of an anti-mold agent layer and an adhesive resin layer, and the anti-mold agent layer is pasted on the adhesive resin layer. Compared with the prior art, the beneficial effects of the utility model are: the high-temperature-resistant and mildew-resistant air filter material has a simple and reasonable structure, economical and practical, and the non-woven fabric protective layer can protect the entire air filter material and can also have a larger size. The honeycomb activated carbon filter layer has a large adsorption capacity for odor, odor, benzene, methanol and other harmful gases and dust. The aromatic polyamide fiber layer has a good material for high temperature and corrosion resistance, and the ultra-fine glass fiber layer It can trap 0.1-0.3 micron dust particles and has a strong dust-proof effect. The anti-mold composition layer can prevent the air filter material from becoming moldy, thereby affecting normal use. Explanation of the drawings Figure 1 is a schematic diagram of the structure of the utility model; Figure 2 is a schematic diagram of the structure of the anti-mold composition layer of the utility model. In the picture: 1. Non-woven fabric protective layer, 2. Aromatic polyamide fiber layer, 3. Honeycomb activated carbon filter layer, 4. Superfine glass fiber layer, 5.
