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.
