Embodiment 1
[0038] An air purification filter element based on a modified glass fiber skeleton, such as Figure 1-5 As shown, it includes a vibration-sealed base 1, and the vibration-sealed base 1 is sequentially installed and fixed with a coarse-effect filter element 2, an activated carbon filter element 3 and a HEPA high-efficiency filter element 4. At the same time, the coarse-effect filter element 2 and the activated carbon filter element 3 and the top of the HEPA high-efficiency filter core 4 are installed on the top pressure seat 5, and the vibration sealing base 1 and the top pressure seat 5 are connected and fixed by a positioning connection fixing mechanism 6;
[0039] The vibration-seal base 1 includes a bottom plate 11, and the surface of the bottom plate 11 is sequentially provided with a first bottom ring groove 12, a second bottom ring groove 13 and a third bottom ring groove 14; wherein the first bottom ring groove 12, the second bottom ring groove The bottom ring groove 13...
Embodiment 2
[0053] The modified glass fiber filter screen is made of modified glass fiber, and the specific preparation process of the modified glass fiber is as follows:
[0054] Step 1, add 100g of neutral polyamide resin into 4L of dimethylformamide and stir to dissolve, then add 12g of nano-titanium dioxide to it, stir and mix evenly to obtain a bonding solution; wherein 40-45mL of dimethicone is added to each gram of neutral polyamide resin In methylformamide;
[0055] Step 2: Add 120g of glass fiber to 1L of bonding solution, then add 23g of 2,3-epoxypropyltrimethylammonium chloride to it, raise the temperature to 60-70°C and ultrasonically shake for 3-4h, then drop by drop Add 33.8g of isophorone diisocyanate, ultrasonicate while adding dropwise, react at a constant temperature for 1-1.5h after the dropwise addition is complete, then cool down to room temperature, remove the glass fiber, and dry it in an oven at 40-50°C to obtain Modified glass fibers.
