Photocatalyst formaldehyde removing spraying agent

The invention relates to a photocatalyst formaldehyde removing spraying agent which is characterized by comprising, by mass, 1%-5% of nano-titanium dioxide, 0.5%-5% of titanium nanophosphate, 0.5%-5% of nano-silica, 0.5%-3% of of nanometer ore powder, 0.1%-0.5% of silk protein, 0.01%-0.1% of dispersant and balance of water to accumulate to one hundred percentage. The agent enables the nano-titanium dioxide to react with nanometer ore powder, silk protein, titanium nanophosphate and the like. The formaldehyde removing spraying agent created by this formula witnesses a higher efficiency in the formaldehyde removal function. The agent has the advantages of removing the indoor formaldehyde thoroughly under natural conditions, and removing various frequent harmful substances such as benzene and amine.
