Abstract

The invention discloses a tourmaline mixture, a tourmaline mixed coating, a preparation method and application. The tourmaline mixture comprises silicon dioxide, tourmaline and a surfactant; the solid content of the silicon dioxide is 0.1%-5%; the solid content of the tourmaline is 0.1%-5%; the tourmaline is in the form of powder, and the particle size of the tourmaline powder is less than 30 microns in terms of D50; the silica is in the form of a powder, and the particle size of the silica powder is 50 [mu] m or less in terms of D50; the mass ratio of the tourmaline to the silicon dioxide is (0.5-5): (1-2); the dosage of the surface active agent is 0.5%-2%, and the percentage is the percentage of the mass of the surface active agent to the total mass of the tourmaline mixture. The prepared tourmaline mixed coating has a rough surface, and the release concentration of negative air ions is high. The preparation method is simple, easy to operate, low in cost, green and environmentally friendly.

Description

technical field [0001] The invention relates to a tourmaline mixture, a tourmaline mixed coating, a preparation method and an application. Background technique [0002] Negative air ions have the functions of sterilizing, reducing dust, cleaning the air, improving immunity, and regulating functional balance, so they are known as "air vitamins and auxin". Tourmaline powder has a natural electrode, can release negative ions without side effects, and has been widely used. [0003] Usually, tourmaline powder is used to enhance the release of negative air ions in the following ways: [0004] Chinese patent document CN113072842A discloses a preparation method of a tourmaline modified solution releasing negative ions, comprising the following steps: S1: weighing a certain amount of tourmaline, mixing tourmaline and cerium oxide to obtain an initial mixture; S2: Add a modified solution to modify the initial mixture to obtain a modified product; S3: mix the modified product with pol...
