摘要

Disclosed are a tourmaline interior wall coating and a preparation method therefor. The coating comprises the following raw materials in parts by weight: 10.00-20.00 parts of 800 mesh ultrafine tourmaline powder; 1.00-3.00 parts of titanium dioxide; 4.00-8.00 parts of lithopone; 16 parts of light calcium carbonate; 5.00-10.00 parts of bentonite; 0.22 parts of a dispersing agent; and 40-51 parts of an adhesive. In the formula for the coating, the tourmaline ingredient contained therein can release negative ions, such that the indoor negative ion concentration can reach 780-1300 ions/cm³.
