Environment-friendly bamboo-wood fiberboard and preparation method thereof

Abstract

The invention discloses an environment-friendly bamboo-wood fiberboard and a preparation method thereof. The surface of the environment-friendly bamboo-wood fiberboard is coated with a water-based environment-friendly coating, wherein the water-based environment-friendly coating is prepared from water-based polyurethane resin, a defoaming agent, a dispersing agent, a delustering agent and a photoinitiator. The water-based environment-friendly coating is coated on the board surface of the environment-friendly bamboo-wood fiberboard to form a compact water-based environment-friendly coating; thewater-based environment-friendly coating is non-toxic and odorless and has high wear resistance, wherein a highly compact protective layer can be formed on the surface of a real object; meanwhile, the water-based environment-friendly coating can isolate contact between the interior of the environment-friendly bamboo-wood fiber board and the outside, volatilization of harmful substances is isolated, emission of volatile organic compounds of the environment-friendly bamboo-wood fiber board is reduced, the environment-friendly standard is achieved, and the processing quality of the environment-friendly bamboo-wood fiber board is improved.

Description

Technical field [0001] The invention belongs to the technical field of bamboo and wood fiberboards, in particular to an environmentally friendly bamboo and wood fiberboard and a preparation method thereof. Background technique [0002] Fiberboard is one of the important varieties of wood-based panels, which are widely used in furniture, interior decoration, packaging and other industries. Ultra-thin high-density fiberboard is generally defined as a fiberboard with a thickness of ≤2mm and a density of 900-1000kg / m3. Formaldehyde is one of the main pollution sources of toxic and harmful gases in interior decoration. It is a strong irritant chemical substance and has been listed as a Class I carcinogen by the World Health Organization. With the improvement of people's living standards and the strengthening of environmental protection awareness, bamboo and wood fiberboard has been widely used as interior decoration materials and the demand is increasing. [0003] The Chinese patent ap...
