The present invention provides a functional additive for formaldehyde removal, a preparation method and application thereof, belonging to the field of additive technology.
The preparation method comprises the steps of:
S1. Stirring microporous powder and chitin with a compatibilizer at 70-78 ℃ for 15-20 min to obtain coated micro powder;
S2. Put the dried coated micro powder into a high-speed mixer equipped with a heating device, then add 2-memidazolone and nano silicon wafers, mix evenly, and obtain a mixture;
S3. Add HDPE powder, foaming agent, and paraffin wax to the high-speed mixer containing the mixture, and continue stirring for 25 minutes to obtain the functional material;
S4. Put the functional material into a conical twin-screw extruder, extrude it into shape, cool it, cut it, and obtain thin sheets;
S5. Put the thin sheet into a ball mill, grind it, and pass it through an 80-120 mesh sieve to obtain a formaldehyde removal functional additive.
The additive of the present invention can be applied to coatings and melamine adhesives, significantly improving the efficiency and durability of formaldehyde purification.
