(2) drying the POM for 3-4 h at the drying condition of 80-90 ℃, then pouring the POM resin and a proper amount of white mineral oil into a stirring barrel, premixing the materials for 3min, and mixing uniformly to obtain an initial mixture;
(3) pouring the composite toughening agent master batch, the antioxidant, the anti-UV agent, the nucleating agent and the initial mixture into the stirring barrel again for mixing for the second time, wherein the mixing time is 3min, and mixing uniformly to obtain a secondary mixed material;
(4) putting the secondary mixed material into a main feeding hopper of a double-screw extruder, heating and melting, extruding and granulating to finally obtain the high-toughness UV-resistant polyformaldehyde resin material; the processing temperature of the double-screw extruder body is controlled to be 100-200 ℃, and the temperature of each zone is as follows: the feeding section and the compression section are 100-200 ℃, the melting section and the metering section are 200 ℃, the die head is 200 ℃, and the rotating speed of a main machine of the die head is 350 r/min.
