Embodiment 1
[0025] A film covering method for an anti-glare lampshade of an LED lamp, the steps of which are as follows:
[0026] Step 1, soak the lampshade in anhydrous ethanol, lye, acid solution, distilled water, methanol in sequence, and obtain the lampshade to be coated after drying;
[0027] Step 2, put the lampshade to be coated into the pre-plating solution, form a uniform and stable first film layer on the surface by means of aeration coating, and dry at a constant temperature;
[0028] Step 3, paste the patterned film on the surface of the lampshade with the film layer, and then heat it for 2 hours, remove the patterned film while it is hot after stabilization, and obtain the rough product of the patterned coated lampshade;
[0029] Step 4: heat and cure the patterned coated lampshade for 4 hours, and then pressurize and cure it for 1 hour to obtain a lampshade with a patterned film.
[0030] The lye of described step 1 adopts the potassium hydroxide of 0.1mol / L.
