Background technique

People spend most of their lives living indoors in homes and workplaces. The quality of indoor air directly affects people's health.

The traditional interior wall paint is mainly used to decorate and protect the indoor wall surface to make it beautiful and clean. It is generally required to have smooth and delicate texture, soft color, certain water and alkali resistance, and has the characteristics of anti-pulverization, scrub resistance, good breathability, convenient construction, stable storage and reasonable price. However, it is difficult to solve the problem of its own environmental protection and possible adverse effects on the human body.

Tourmaline, also known as tourmaline or tourmaline, is a complex silicate containing boron. It has a Si ₆ O ₁₈ complex tricyclic ring structure. This structure makes the tourmaline stone subjected to external temperature, Under the influence of pressure and other changes, there will be thermoelectric effect, piezoelectric effect and electrostatic field effect. These effects make tourmaline have special properties such as far-infrared radiation, release of negative ions, adsorption effect and bioelectric characteristics. These characteristics are in It has extremely broad application prospects in the fields of health and environmental protection.

(2) The influence of the various raw material dosages on the preparation of the technical index of the negative ion amount that produces negative ion indoor paint is complicated, and the formulation of the Marlin interior wall paint cannot be obtained through a simple limited test. As can be seen from Figures 1 and 2, the amount of negative ions increases with the increase of the amount of tourmaline powder; from Figures 3-7, although the amount of negative ions increases with the increase of the amount of tourmaline powder, but Due to the different amount of titanium dioxide, the amount of negative ions produced is also different. The amount of titanium dioxide can be comprehensively considered according to the amount of negative ions generated and the price of titanium dioxide; from Figures 8 to 14, it can be seen that with the increase in the amount of tomaline powder, due to The amount of zinc-barium white added is different, resulting in an anion generation rate that is sometimes not current.

For example, if the customer requires the number of negative ions produced by the Tomarin interior wall coating provided by the present invention to be 1200/cm ³ , examine the amount of titanium dioxide and zinc-barium white. Figure 24 shows that the formulation of 0.75kg titanium dioxide and 4kg zinc-barium white can Meet the requirements of the indicator. Figure 26 shows that the formula of 2.05kg titanium dioxide and 6kg zinc barium white can meet the indicator requirements. Figure 27 shows that the formula of 2.60kg titanium dioxide and 7kg zinc barium white can meet the indicator requirements. Figure 28 shows 3.00kg titanium dioxide The formula with 8kg zinc-barium white can meet the requirements of the index.
