A kind of bamboo-wood composite board and preparation method thereof

Abstract

The invention relates to the technical field of composite boards, and discloses a bamboo and wood composite board and a method for manufacturing the same. The bamboo and wood composite board comprises bamboo layers, wood veneer layers, more than two non-woven fabric layers and adhesive. The corresponding wood veneer layer is arranged between each two bamboo layers, the total quantity of the bamboo layers and the wood veneer layers ranges from 14 to 35, the non-woven fabric layers are arranged between the bamboo layers and the wood veneer layers, the various layers are adhered with one another by the adhesive and are integrally laminated, a surface layer and a bottom layer of the bamboo and wood composite board are bamboo layers respectively, sealing wax layers with waterproof effects are arranged on the surfaces of the bamboo and wood composite board, the bamboo layers are bamboo chip layers or bamboo curtain layers, the thickness of each bamboo layer ranges from 0.5mm to 1.5mm, the thickness of each wood veneer layer ranges from 1.5mm to 2.0mm, the adhesive is made of phenolic resin adhesive with the solid content of 50%, impregnating compounds and more than one type of waterproof agents, mothproofing agents or inorganic flame retardants are added into the phenolic resin adhesive, and the adhesive is applied to double surfaces of each of the bamboo layers, the wood veneer layers and the non-woven fabric layers. The method for manufacturing the bamboo and wood composite board includes steps of manufacturing the adhesive; treating materials of the bamboo layers; treating wood veneers; arraying and assembling blanks; laminating and forming the blanks; treating the surfaces of the blanks and warehousing the finished product.

Description

technical field [0001] The invention relates to the technical field of composite boards, in particular to a bamboo-wood composite board and a preparation method thereof. technical background [0002] In my country's traditional furniture, a single raw material such as bamboo or wood is generally used. Because of the shape, size, and material properties of the raw material, the performance of the manufactured furniture is limited to a certain extent. For example, bamboo is loved by everyone because of its good toughness, high elastic modulus, high strength, wear resistance, elegant and soft color, beautiful appearance, and short bamboo growth cycle. However, bamboo is affected by soil quality, climate, sunshine, Influenced by different growth cycles, the density, water content, diameter grade and size are uneven, the thickness of bamboo is different, the yield rate of young bamboo is low, and the age of bamboo is also different. The technical feature is that the moisture cont...

[0002] In my country's traditional furniture, a single raw material such as bamboo or wood is generally used. Because of the shape, size and material properties of the raw material, the performance of the furniture is limited to a certain extent.

For example, bamboo is loved by everyone because of its good toughness, high elastic modulus, high strength, wear resistance, elegant and soft color, beautiful appearance, and short bamboo growth cycle. However, bamboo is affected by soil quality, climate, sunshine, Influenced by different growth cycles, the density, water content, diameter grade and size are uneven, the thickness of bamboo is different, the yield rate of young bamboo is low, and the age of bamboo is also different. The technical feature is that the moisture control before glue is relatively easy. , but the water content after glue is difficult to control, so there are problems such as difficult bamboo processing, low automation level, rough production and processing, etc.

High wood utilization rate, easy processing, good flatness, easy to nail, easy to cut, easy to splice the product during use, but poor toughness, low elastic modulus, large coefficient of water expansion, shortage of wood resources, and long growth cycle, Harvesting timber has a great impact on the ecology

Wooden veneer has high fiber content, regular fiber shape, good mechanical properties, and good processability; bamboo veneer has good compressive and bending strength, small shrinkage, and high degree of splitting, elasticity and toughness; However, whether it is bamboo veneer or wood veneer, there are problems of poor insect resistance, mildew resistance and short service life.
