wherein the functional UV gloss oil coating comprises UV gloss oil; the particle size of the tourmaline superfine powder is 4000-6000 meshes; calculated by the total mass of the functional UV gloss oil coating, the tourmaline superfine powder accounts for 5-15% by mass;
(3) Uniformly coating the functional UV gloss oil coating prepared in the step (2) on the heat dissipation substrate layer of the electric heating plate in the step (1), and curing to form a UV gloss oil layer with tourmaline particles, so as to prepare the negative ion integrated electric heating plate;
the method for preparing the functional UV gloss oil coating containing the tourmaline micropowder in the step (2) comprises the following steps: grinding a tourmaline raw material to 4000-6000 meshes, carrying out surface modification to obtain tourmaline superfine powder, adding the tourmaline superfine powder, a diluent, a cross-linking agent, an initiator, a film-forming agent propylene glycol monobutyl ether and a flatting agent into UV gloss oil according to a proportion, then adding the UV gloss oil and the flatting agent into a grinding machine, and continuously grinding to obtain the functional UV gloss oil coating.
7. The preparation method of claim 6, wherein the method for preparing the functional UV varnish containing tourmaline micropowder of step (2) comprises: grinding the tourmaline raw material to 4000-6000 meshes to obtain tourmaline superfine powder, adding the tourmaline superfine powder into UV gloss oil, and then adding the mixture into a grinding machine to continuously grind to obtain the functional UV gloss oil coating.
8. The preparation method according to claim 6 or 7, wherein the ground tourmaline micropowder is surface-modified and then added to UV varnish.
9. Use of an anion integrated electric hot plate according to any of claims 1 to 5 in the form of floor heating, kang heating, wall heating or for making heating pictures.
