Technical Field

The invention relates to the technical field of bamboo-wood-carbon fiber plates, in particular to a high-strength bamboo-wood-carbon-fiber high-magnesium gel structure plate and a preparation method thereof.

Background

at present, wood fiber is limited to be produced in the application field only by medium density fiberboard, the production process is divided into a wet process and a dry process, the wet process for producing the fiberboard needs to consume a large amount of water resources and can cause serious wastewater pollution, so the wood fiber is eliminated, the dry process adopted at present is to obtain the medium density fiberboard by hot press molding the wood fiber through series procedures of fiber drying, sizing, molding and the like, but wood adhesive is applied in the production process, more than 90 percent of the wood adhesive belongs to formaldehyde glue at present, the usage amount of the urea-formaldehyde glue is the largest, so most of the obtained products are aldehyde-containing fiberboards, harmful substances such as free formaldehyde and phenol and the like generated in the production and use processes of the aldehyde-containing fiberboards are more and more concerned by people, particularly, after toxic substance air transmission control measures for reducing formaldehyde emission of composite wood products are issued by the air resource Committee (CARB) of California, 18 Rifame, 4.S.s.4.2008, regulations that prevent both composite wood products that do not comply with CARB certification and finished products containing composite wood products from entering the U.S. market present a significant challenge to man-made board enterprises and furniture enterprises in our country and even throughout the world.

Therefore, the existing decoration of furniture walls is generally improved on the safety use function of bamboo-wood-carbon fiber boards, for example, the manufacturing method of a glue-free high-density fiberboard provided in chinese patent CN 103029196 a can increase the surface area of wood fibers, expose more natural substances with adhesive property on the surface, facilitate the generation of more adhesive substances in the subsequent hot pressing process, combine the wood fibers together, in the hot grinding and hot pressing process, the cellulose and hemicellulose parts in the wood fibers are more easily hydrolyzed to generate furfural compounds, thereby further promoting the formation of adhesive compounds between the furfural compounds and lignin with phenolic structures, therefore, the glue-free high-density fiberboard can be manufactured, the application field of the glue-free fiberboard is greatly expanded, and the glue-free high-density fiberboard is particularly suitable for the furniture field, and can realize low-cost and environment-friendly high-end furniture, however, the strength of the fiberboard is not high, effective water and fire prevention cannot be performed, and meanwhile, the sound insulation and heat insulation effects are not good enough, so that the fiberboard cannot be used as a building structural board for inner and outer walls of an assembled house, and therefore, the high-strength bamboo-wood-carbon-fiber high-magnesium gel structural board and the preparation method thereof are provided to solve the problems.
