3D honeycomb type paint mist filter bag and preparation method thereof

[0026] A preparation method of a 3D honeycomb paint mist filter bag, comprising the steps of:

[0027] (1) Preparation of pyrrolyl polystyrene: Add 100 g of styrene and 15 g of 1-(4-vinylbenzyl) pyrrolidine to 400 g of hexane solvent, stir to dissolve, then add 30 g of tetramethylethylenediamine and 18 g of n-Butyllithium, carry out polymerization reaction at 80°C for 3 hours, after the reaction is completed, add ethanol to the solvent, evaporate the solvent to dryness, and obtain pyrrolyl polystyrene;

[0028] (2) Preparation of pyrrolyl polystyrene cross-linked glass fiber: take 80g of pyrrolyl polystyrene obtained in step (1) and dissolve it in 600g of carbon tetrachloride, then add 120g of glass fiber to it, after ultrasonic dispersion is uniform, Then add 40g of aluminum chloride to it, carry out crosslinking reaction at 85°C for 24h, after the reaction is finished, filter, wash and dry the reaction product to obtain pyrrolyl polystyrene crosslinked glass fiber;
