Technical Field

The invention relates to the field of furniture, in particular to a floor coating capable of decomposing formaldehyde.

Background

With the improvement of the cultural level of living materials of people, the interior decoration becomes fashionable, but the indoor air pollution is more and more serious. Formaldehyde is one of the most typical, most serious pollutants in indoor environments. It is known that people living in an environment with excessive formaldehyde gas concentration can cause great harm to human health for a long time, and sometimes even induce cancer. The limit value of the concentration of formaldehyde pollutants in indoor air specified by national standard of China is 0.08 mg/m 3. The condition that the concentration of formaldehyde in indoor environment of China exceeds the standard is still serious so far, and according to the sampling detection survey of the national disease control center, the concentration of formaldehyde in more than 60% of newly-decorated residents in China exceeds the standard, which can cause great harm to the health of people. With the improvement of environmental awareness, people pay more attention to indoor formaldehyde pollution, and complaints caused by the over-standard indoor formaldehyde concentration are frequently reported in recent years. Therefore, the research on formaldehyde purification technology to effectively eliminate the indoor formaldehyde concentration has become an urgent task for improving the living environment of people

as a furniture raw material, the floor is very popular with consumers due to light weight and beautiful appearance. However, many of the current floors, even wooden furniture, contain large amounts of formaldehyde which can pose serious health risks to humans, and thus, protection against formaldehyde in such wood must be taken.

there have been related developments of chitin to decompose formaldehyde, but such developments have not been applied to floor formaldehyde-proofing applications for some time.

Disclosure of Invention
