Camellia-oleifera-based particle board and preparation method thereof

Abstract

The invention discloses a camellia-oleifera-based particle board and a preparation method thereof. The camellia-oleifera-based particle board is a sandwich-structure particle board formed by sequentially compounding a surface layer, a core layer and a surface layer, and the surface layers and the core layer are formed in a manner that camellia oleifera fruit shell particles and wood shavings are taken as main raw materials, and an adhesive is added for gluing; and the adhesive is a melamine modified urea-formaldehyde resin adhesive. The camellia-oleifera-based particle board disclosed by the invention has good physical and mechanical properties; compared with a traditional wood particle board, the camellia-oleifera-based particle board has the advantages that recycling of agricultural and forestry waste is achieved; compared with wood, the camellia-oleifera-based particle board is lower in price; and compared with an existing camellia-oleifera-based particle board, the camellia-oleifera-based particle board has the advantages that production cost can be reduced, and environmental pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of utilization of agricultural and forestry waste and composite materials, in particular to a camellia oleifera-based particle board and a preparation method thereof. Background technique [0002] Camellia oleifera is a unique woody edible oil tree species in my country, which is abundantly distributed in Hunan, Jiangxi, Guangxi and other central and southern provinces of China. In 2019, China's annual output of camellia oleifera reached 4.4 million hectares, with 2.4 million tons of fruit harvested. High-quality edible oil is mainly extracted from seeds, and major by-products such as Camellia oleifera husk residue still account for 50% to 60% of the total output, about 1.8 million tons per year. [0003] The limitations of the utilization of agricultural waste, due in part to the lack of practical reuse methods, and the lack of understanding of the chemical and physical properties of Camellia oleifera husk...

AI Technical Summary

Problems solved by technology

For example, the existing methods of using camellia oleifera husks to prepare particle boards usually require microwave radiation or long-term hot water soaking and then treatment with sodium hydroxide solution, which has potential problems such as waste liquid recovery and environmental pollution; existing plant fibers Particleboard usually requires the use of isocyanate-containing adhesives, which require a higher temperature for curing (220 ° C ~ 235 ° C) during processing, which is difficult to process. The high price of isocyanate adhesives increases the production cost of the board. Conducive to the Industrial Development of Particleboard
