Abstract

The invention discloses a bamboo leftover mixed fiberboard comprising chemical fibers, plant fibers and plant powder particles; a mixed fiber mat comprises the components in percentage by weight: 10-20% of chemical fibers, 20-40% of plant fibers and 40-70% of plant powder particles. The mixed fiber mat has the thickness of 5-20mm and the density of 0.15-0.6g / cm<3>, and the sizes of the plant powder particles are smaller than 80 meshes. The invention further discloses a preparation method of the bamboo leftover mixed fiberboard. The preparation method comprises the following processes: bale opening, coarse opening, fine opening, screening and drying, chemical fiber measuring, fiber measuring, primary mixing, uniform mixing, net preforming, air laying, heating melting, cold pressing, coolingand cutting. By using the mixed fiber mat prepared by using the preparation method, the defects of release of formaldehyde existing in the fiberboard and edge breakage existing in board cutting are overcome; and the mixed fiber mat has the characteristic of good air permeability and is particularly suitable for an application as a board for furniture.

Description

technical field [0001] The invention relates to the technical field of bamboo and wood board applications, in particular to a bamboo and wood waste mixed fiber board and a manufacturing method thereof. Background technique [0002] Plates are usually used when people make tables, chairs, bookshelves, cabinets, tatami and other furniture products. Important sheet for panel products. Fiberboard is also known as density board. The existing fiberboard is a wood-based panel made of wood fiber or other vegetable fiber and applied with urea-formaldehyde resin or other suitable adhesives. Taking tatami as an example, the core layer of tatami on the market still uses a large amount of glue binder in the production process, and is molded by bonding plant fibers and glue. Such molded products contain formaldehyde, which is not environmentally friendly and cannot be recycled. The glue is also prone to mildew and changes the quality of the product, and it is also easy to harden, reduci...
