Abstract

The invention relates to adhesive for collecting formaldehyde and paint for collecting the formaldehyde, both of which use formaldehyde collecting agent as a composition of active components. The adhesive is used for adhesion of the outmost layer in a man-made board or adhesion and edge sealing at a kerf of the man-made board, can effectively absorb formaldehyde released by the man-made board, does not cause influence on the adhesive strength of the board, and is comparatively cheap. The paint is used for painting indoor walls, absorbs the formaldehyde in the indoor air, can also be used for painting the surface of the man-made board, seals and absorbs formaldehyde gas, and reduces the release amount of the formaldehyde. Compared with the prior art, the adhesive and the paint for collecting the formaldehyde have the advantages that the adhesive and the paint are cheap, can efficiently adsorb the formaldehyde and generate stable compounds, and do not re-decompose and release the formaldehyde, so the adhesive and the paint cannot generate other secondary pollutants.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an adhesive and a coating for collecting formaldehyde prepared by using a formaldehyde collector as an active component. Background technique [0002] With the improvement of living standards and the continuous strengthening of health awareness and environmental protection awareness, people pay more and more attention to their indoor environment. People mostly use various new materials such as wood-based panels for interior decoration, but plywood, particleboard, density board, blockboard and other wood-based panel products made of urea-formaldehyde resin glue, phenolic resin glue, melamine-formaldehyde resin glue, etc. While beautifying the living room, it becomes the main source of indoor formaldehyde. The free formaldehyde released in the production and use of wood-based panels pollutes the living environment and damages human health. The reasons for the release of forma...
