Description

technical field [0001] The invention relates to an electrical appliance coating material, in particular to an electrical appliance coating material based on polyvinyl alcohol emulsion and a preparation method thereof. Background technique [0002] Electromagnetic radiation, also known as electronic smog, is composed of electric energy and magnetic energy transferred together in space, and the energy is generated by the movement of electric charges. For example, electromagnetic energy is generated by moving electrical charges from a radio frequency antenna that is transmitting. The electromagnetic "spectrum" includes all kinds of electromagnetic radiation, from very low frequency electromagnetic radiation to very high frequency electromagnetic radiation. Electromagnetic radiation can cause various effects on the human body: for example, electromagnetic radiation is the main cause of cardiovascular disease, diabetes, and cancer mutation; electromagnetic radiation causes direc...
