Technical Field

The invention relates to the field of chemistry and chemical engineering, in particular to a photocatalyst preparation for efficiently removing formaldehyde.

Background

The formaldehyde is a colorless, inflammable and odorous chemical substance and is harmful to human bodies, along with the gradual improvement of the living standard of people at present, households, paints and adhesives made of raw materials containing the formaldehyde can release harmful formaldehyde, the formaldehyde is extremely harmful to the human bodies, children and old people are sensitive to the contact of the formaldehyde, people suffering from respiratory diseases or other chronic diseases are more sensitive to the contact of the formaldehyde, and the formaldehyde has an irritation effect on the harm of the human bodies, such as irritation on skin mucous membranes and respiratory tracts, and symptoms of tearing, sore throat, cough, shortness of breath, dyspnea and the like, and also has a sensitization effect and a mutation-causing effect.

Disclosure of Invention

The invention mainly aims to provide a photocatalyst preparation for efficiently removing formaldehyde, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention adopts the technical scheme that:

a high-efficiency formaldehyde-removing photocatalyst preparation comprises the following components in percentage by mass: 0.3 to 0.7 percent of nano titanium dioxide, 2 to 6 percent of formaldehyde scavenger, 1.5 to 4.5 percent of chitin, 7 to 13 percent of penetrating agent and water which is supplemented to 100 percent.

Further, the following combinations are included by mass percentage: 0.4 to 0.6 percent of nano titanium dioxide, 3 to 5 percent of formaldehyde scavenger, 2 to 4 percent of chitin, 7.5 to 12.5 percent of penetrating agent and water which is supplemented to 100 percent.

Further, the following combinations are included by mass percentage: 0.5% of nano titanium dioxide, 4% of formaldehyde scavenger, 3% of chitin and 10% of penetrating agent, and water which is supplemented to 100%.

Further, the nano titanium dioxide is titanium dioxide with a shell-core structure.

Further, the formaldehyde scavenger is ethylene urea.

Further, the penetrating agent is polyoxyethylene fatty alcohol ether.

Compared with the prior art, the invention has the following beneficial effects: the composite material is prepared by titanium dioxide with a shell-core structure, ethylene urea, chitin and polyoxyethylene fatty alcohol ether in a specific proportion, has nontoxic and environment-friendly components, can effectively remove formaldehyde, and is suitable for a broad spectrum of environment.
