Problems solved by technology

However, the formaldehyde collectors prepared by these methods have low efficiency in collecting formaldehyde
In JP1999343473, tourmaline is used to catalyze the reduction of formaldehyde, but this method will generate methanol while reducing formaldehyde, thus causing secondary pollution

Abstract

This invention relates to a adhesive and a dope used for catching formaldehyde, both takes formaldehyde collector as active ingredient. This adhesive is used for gluing outer layer or kerf section of panel, can efficiently absorb formaldehyde liberated by panel, and has no impact to adhesion strength of panel. This dope is used for washing indoor wall; to absorb formaldehyde in the indoor air; also be used for surface washing of panel, absorb formaldehyde gas, reduce releasing of formaldehyde. Comparing with existing technology, this invention has such merit: cheapness, efficiently, and can generate stable compound, no longer discharge formaldehyde gas, thus unable to generate other secondary pollutant.

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...
