Embodiment 1
[0040] This embodiment is an automobile air filter assembly. The modified silicone reinforced filter paper layer 6 and the flame retardant layer 7 are prepared according to the conventional production method of the filter element 5, and then the filter element 5 is installed in the lower shell of the filter. 4, the filter upper case 1 is installed to form the automobile air filter assembly;
[0041] Wherein the modified silicone reinforced filter paper layer 6 is prepared by the following steps:
[0042] S1: Add dry chloroplatinic acid to the distilled and dried isopropanol solution, and stir to obtain a catalyst;
[0043] S2: Add glycidyl methacrylate, toluene, an inert solvent, and a catalyst to a three-necked flask equipped with a thermometer, a condenser, a stirrer, and a water separator, heat up to 65°C under stirring, reflux for 1 hour, and dropwise add Hydrogen silicone oil, control the dropping rate at 1 drop / s, raise the temperature to 85°C, add allyl polyoxyethylene...
