Composite fiber plate

Abstract

The invention relates to a composite fiber plate. The composite fiber plate contains the following components in parts by weight: 120-130 parts of wood fibers, 7-15 parts of carbonic acid fibers, 20-30 parts of an epoxy resin adhesive, 10-11 parts of nano-nickel, 100-120 parts of absolute ethyl alcohol, 30-35 parts of polylactic acid fibers, 2-5 parts of n-butyl alcohol, 20-30 parts of a waterborne polyurethane adhesive, 10-15 parts of ammonium chloride, 20-60 parts of a styrene-acrylic emulsion, 1-3 parts of nano-pearl powder, 3-5 parts of silicon dioxide, 3-5 parts of chitin whiskers and 0.3-0.5 part of zinc borate. Compared with the prior art, the prepared composite fiber plate does not contain free formaldehyde and has the characteristics of no formaldehyde release, low water absorption and thickness swelling rates, good mechanical property and the like, and a product has the characteristics of excellent mechanical property and the like; and the composite fiber plate can be appliedto indoor decoration, furniture processing and the like.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a composite fiber board. Background technique [0002] Fiberboard is a wood-based panel made by interweaving lignocellulosic fibers and utilizing their inherent adhesive properties. Adhesives and additives can be applied during the manufacturing process and are widely used in furniture, interior decoration, packaging and other industries. With the improvement of people's living standards, the performance requirements of the board are getting higher and higher. Especially the amount of formaldehyde released from the board directly affects the physical and mental health of human beings. According to the analysis of the results of national supervision and spot checks in the past 10 years, most of the unqualified aspects are mainly excessive formaldehyde emission, high water absorption thickness expansion rate, and insufficient static bending strength, while other unqualified pro...
