Description

Technical Field

[0001] The invention relates to the technical field of air purification products, and in particular to an air purification composition capable of generating negative oxygen ions. Background Art

[0002] With the rapid development of modern science and technology and industry, people's quality of life is constantly improving, but the problem of environmental pollution is becoming increasingly serious. Especially in the field of building decoration, a large amount of chemical decoration and decorative materials enter the room, resulting in increasingly prominent indoor air pollution problems. Among these pollutants, harmful gases such as formaldehyde are particularly harmful to human health. Therefore, it is particularly important to develop products that can effectively purify indoor air and increase the concentration of negative oxygen ions.

[0003] Negative oxygen ions refer to oxygen ions that have acquired one or more negative charges. They are one of the important indicators of air quality. Negative oxygen ions have many benefits for human health, such as improving cardiopulmonary function, enhancing immunity, relieving stress and improving sleep quality. Therefore, adding negative oxygen ion additives to purification products to generate negative oxygen ions has become a hot topic in current research.

[0004] At present, there are various technologies for preparing negative oxygen ion products. Among them, a common method is to add materials that can release negative oxygen ions, such as tourmaline powder, to the purification products. Tourmaline has thermoelectricity and piezoelectricity. As long as there are slight changes in temperature and pressure, it can cause electric heat and voltage difference, thereby ionizing the ions in the air and converting them into negative air ions. However, the products prepared by this method on the market still need to be improved in terms of negative oxygen ion release and stability, and their use methods are relatively single and have a narrow range of applications. Summary of the invention

By comparing experimental group 1 and experimental group 8, it can be obtained that the coating prepared by the air purification composition proposed by the scheme of the present application can also produce a large amount of negative oxygen ions and effectively remove indoor formaldehyde. By comparing experimental group 4 and experimental group 9, it can be obtained that the spray paint prepared by the air purification composition proposed by the scheme of the present application can also produce a large amount of negative oxygen ions and effectively remove indoor formaldehyde. It can be seen from this that the air purification composition proposed in the present application can not only effectively produce more negative oxygen ions, but also decompose indoor formaldehyde, and the use method is diverse and convenient, and has a wide range of applications.
