Problems solved by technology

[0003] At present, some environmentally friendly wall materials have appeared. These wall materials add tourmaline to the raw materials, and release negative oxygen ions through tourmaline to achieve the purpose of purifying the air. However, the amount of negative oxygen ions released by tourmaline is uncertain, resulting in the purification effect of these wall materials. Different, for example, a green environment-friendly tourmaline composite home improvement material disclosed in Chinese invention patent CN 104386982 A, including the following raw materials in parts by weight: tourmaline powder: 2-20 parts; slag: 20-80 parts; activated carbon 2-10 parts; Binder: 5-40 parts; Excipients: 1-40 parts; Air-entraining agent: 0.1-0.3 parts
According to investigation and research, the most standard tourmaline releases only about 6,000 negative oxygen ions per cubic centimeter. The release of negative oxygen ions is small, the purification efficiency is low, and the purification effect is poor.

Abstract

The invention relates to the technical field of indoor decorative coatings, in particular to a decorative coating capable of adsorbing and decomposing formaldehyde and releasing negative oxygen ions,and aims to further improve the purpose that the decorative coating releases high-concentration negative oxygen ions to decompose indoor formaldehyde. According to the decorative coating capable of adsorbing and decomposing formaldehyde and releasing negative oxygen ions, the decorative coating comprises the following components in parts by weight: 200-300 parts of a coating additive and 80-100 parts of water. All the components of the prepared decorative coating have a synergistic effect and can release high-concentration negative oxygen ions, the concentration of the negative oxygen ions reaches 80,000 per cubic centimeter, the generated negative oxygen ions can directly decompose formaldehyde, methylbenzene and other pollutants into non-toxic and odorless carbon dioxide and water, indoor pollution is relieved, and the decorative coating has a remarkable influence on air purification and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of interior decorative coatings, in particular to a decorative coating that absorbs and decomposes formaldehyde and releases negative oxygen ions. Background technique [0002] Negative oxygen ions are known as "air vitamins". Negative oxygen ions can directly decompose formaldehyde, toluene and other pollutants into non-toxic and tasteless carbon dioxide and water, relieve indoor pollution, and have a significant impact on air purification. Moreover, medical research shows that , Negative oxygen ions increase the oxygen content in the blood, which is beneficial to the transportation, absorption and utilization of blood oxygen, and has the functions of promoting human metabolism, improving human immunity, enhancing human muscle energy, and regulating the balance of body functions. According to research, negative oxygen ions have the functions of inhibiting, alleviating and adjuvant treatment on 7 systems of ...
