Abstract

The invention discloses an environmentally-friendly formaldehyde purification spray capable of releasing negative oxygen ions, and a preparation method thereof, wherein the raw materials comprise, byweight, 3-8 parts of a modified photocatalyst, 4-6 parts of negative ion powder, 0.3-1.2 parts of essence, 2-4 parts of a plant extracting solution, 60-80 parts of water and 2-4 parts of nano-silver ions. According to the invention, the environmentally-friendly formaldehyde purification spray capable of releasing negative oxygen ions, and the preparation method thereof are designed, and the process is reasonable in design, wherein the negative ion powder is prepared from tourmaline powder and lanthanum series elements according to a mass ratio of 2:3, can release negative oxygen ions, and candegrade formaldehyde and other harmful substances, so that the formaldehyde degradation efficiency is effectively improved through the synergistic effect of the negative ions and the photocatalysis while the components of the photocatalyst are optimized so as to further improve the selectivity of the spray to formaldehyde, substantially optimize the formaldehyde degradation effect and achieve highpracticability.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an environment-friendly formaldehyde purification spray for releasing negative oxygen ions and a preparation method thereof. Background technique [0002] Formaldehyde, colorless and irritating gas, chemical formula HCHO or CH 2 O, molecular weight 30.00, also known as formic aldehyde; colorless, irritating to human eyes and nose. Nowadays, with the progress and development of social science and technology, a large amount of housing area has been put into use, followed by a large amount of organic volatile gases, such as formaldehyde, benzene, toluene, dibenzene, VOC and other harmful gases. When indoor formaldehyde When the concentration is greater than 0.08mg / m3, it will cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc., which not only affects our life and health, but also affects people's quality of...
