Embodiment 1

[0022] A composite vehicle-mounted air-conditioning filter element according to the embodiment of the present invention is prepared according to the following steps:

[0023] Step 1): Weigh 0.2mol of magnesium chloride and 0.1mol of ferric chloride and dissolve them in 100mL of deionized water, stir to dissolve completely, then quickly add 1mol of NaOH, 100W ultrasonic for 30min, and transfer the mixture into the reaction kettle after ultrasonic , and reacted at 120°C for 24 hours. After the reaction solution was centrifuged, washed three times with deionized water and ethanol, and dried and ground, the product obtained was hydrotalcite LDH; step 2): Weigh 0.6g LDH and 3g melamine and mix thoroughly, set In a muffle furnace, it is calcined at 300°C for 6 hours in a nitrogen atmosphere, and then dispersed in water. The resulting product is LDH / g-C 3 N 4 dispersion; step 3): carbon fiber felt in H 2 SO 4 Soak in the solution for 1h, then wash with ethanol and water in turn, a...

Abstract

The invention discloses a composite vehicle air conditioning filter core and a preparation method thereof. The preparation method includes: 1), soaking a carbon fiber felt in an H2SO4 solution, washing the carbon fiber felt with ethanol and water and then drying the same; dissolving LDH (lactate dehydrogenase) / g-C3N4 in water to obtain dispersing fluid, placing the dried carbon fiber felt in the LDH / g-C3N4 dispersing fluid for soaking for 10 minutes, washing the carbon fiber felt with water prior to drying the same, then soaking the carbon fiber felt in 1wt% of a PVA (polyvinyl acetate) solution for 1 hour, and washing the same with water prior to drying the same; 3), repeating the step 2) for multiple times, soaking an obtained loaded carbon felt in a glutaraldehyde solution for 1 hour, and washing the loaded carbon felt with water prior to drying the same to obtain carbon felt loaded LDH / g-C3N4 composite filter core. The filter core is composed of hydrotalcite LDH and graphite phasecarbon nitride g-C3N4, so that stacking agglomeration of LDH can be effectively reduced, the active area of g-C3N4 is increased, and catalytic efficiency and adsorption efficiency of composites are enhanced; through the load of the carbon fiber felt, the loading material has good adsorption effect and stability.

Description

technical field [0001] The invention relates to an air-conditioning filter element, in particular to a composite material vehicle-mounted air-conditioning filter element and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the penetration rate of automobiles is also increasing, which brings convenience to people's travel and aggravates environmental air pollution. Motor vehicle exhaust has gradually become one of the main sources of urban air pollution. Inhalable particulate matter (PM10 and PM2.5) has small particle size, large specific surface area, strong activity, and the surface is easily loaded with toxic and harmful substances, and lasts for a long time in the ambient air, which can be inhaled by the human body and deposited in the respiratory tract, alveoli, etc. It causes many diseases and is very harmful to human beings. Due to the serious air pollution on the road and the small space in the...
