Abstract

A formaldehyde eliminating agent for indoor space is proportionally prepared from amino compound, cyanamine compound, water-soluble high-molecular hydroxy compound, water, and TiO2.

Description

technical field [0001] The present invention relates to the technical field of eliminating agent, relate to a kind of solvent that can eliminate formaldehyde more specifically. Background technique [0002] At present, after decorating the family, if the decorative materials that do not meet the environmental protection requirements are used, this material will release a harmful gas containing formaldehyde, and the human body will be poisoned after absorbing the gas containing formaldehyde. It will also endanger people's lives and safety. Therefore, after the home is decorated, it is necessary to eliminate harmful substances containing formaldehyde in the room to ensure that the harmful gases in the room cannot exceed the standards set by the state, otherwise it will affect people's health. Health, the method that people usually adopt to eliminate indoor harmful air is to use formaldehyde scavenger, which can easily eliminate indoor harmful gases containing formaldehyde subs...
