Efficient environment-friendly composite nano-photocatalyst formaldehyde scavenger and preparation method thereof

Abstract

The invention relates to an efficient environment-friendly composite nano-photocatalyst formaldehyde scavenger which comprises the following raw materials: a semen cassiae extract, a sansevieria trifasciata extract, an aloe extracting solution, a pomelo peel extracting solution, nano negative ion powder, titanium dioxide, a dispersing agent, a penetrating agent and deionized water. The efficient environment-friendly composite nano-photocatalyst formaldehyde scavenger has the beneficial effects that formaldehyde distributed in indoor air can be rapidly and efficiently removed, and free formaldehyde which is not temporarily released to the surface in materials such as artificial boards and the like can be thoroughly removed; the nano negative ion powder can continuously release negative ions by micro-electrolyzing water in air, so that the indoor negative ion concentration reaches a relatively stable higher level, and the efficient environment-friendly composite nano photocatalyst formaldehyde scavenger has the characteristics of no energy consumption, no generation of ozone and active oxygen and the like, namely, the efficient environment-friendly composite nano photocatalyst formaldehyde scavenger has an efficient and lasting formaldehyde removal effect.

Description

Technical field [0001] The present invention belongs to the technical field of building materials, and more particularly to a highly efficient environmentally friendly composite nano-photocatalytic formaldehyde scavenger and a preparation method thereof. Background technique [0002] Formaldehyde is a colorless forefront irritating gas, has been determined by the World Health Organization as a carcinogenic and deformity, formaldehyde release contamination can cause eye tears, cornea, conjunctiva congestion, skin allergy, discomfort, sorphosis, cough, acute Respiratory diseases such as bronchitis can also cause nausea, vomiting, gastrointestinal disorders, severe persistent headache, pneumonia, pulmonary edema, loss of appetite, and even cause death, according to the investigation of American medical departments, formaldehyde release pollution is caused The main reason for the increase in asthma in children aged 3-5. The main source of formaldehyde in modern life includes decorati...

Problems solved by technology

There are many kinds of existing air purification products, each with its own characteristics, but they all have certain deficiencies at the same time. For example, the adsorption of pollutants by adsorption-type air purifiers is not firm, and the adsorbent is easy to reach adsorption saturation, which needs to be replaced or regenerated regularly , so that the cost of follow-up treatment is relatively increased; the oxidative bactericidal disinfectant is a quick-acting, consumable antibacterial agent with poor persistence; the formaldehyde scavenger has low removal efficiency and short action time, which is easy to cause secondary pollution to the environment
