A kind of inorganic flame-retardant bamboo-wood composite ecological fiber planting board and its production method

Abstract

The invention discloses an inorganic flame retarding bamboo and wood composite ecological plant fiber board and a production method thereof. The inorganic flame retarding bamboo and wood composite ecological plant fiber board comprises a plant fiber core board. The inner surface and the outer surface of the plant fiber core board are paved with single bamboo boards. Wood boards are arranged between the single bamboo boards and the plant fiber core board. The wood boards and the single bamboo boards are adhesively connected through inorganic flame retarding adhesive material layers, and the wood boards and the plant fiber core board are adhesively connected through inorganic flame retarding adhesive material layers. The plant fiber core board is board materials made of plant fibers and inorganic flame retarding adhesives. According to the inorganic flame retarding bamboo and wood composite ecological plant fiber board, the single bamboo boards are arranged on the surface layers of the plant fiber core board and are formed by slicing thin bamboos, so that the surface layers of the fiber board are orderly in texture and not prone to abrasion or damp, good protection is provided, the whole strength and the machining performance of the straw fiber board are greatly improved, and the inorganic flame retarding bamboo and wood composite ecological plant fiber board is clear in bamboo texture, attractive in board surface, pleasant in bamboo fragrance and elegant in texture and achieves high quality and grade of the straw fiber board; due to the arrangement of the wood boards, the mechanical performance of the whole fiber board is improved, the strength of the fiber board is improved, no artificial formaldehyde is released from the board, and the fire-protection grade can reach the grade A3 or more than the grade A3.

Description

technical field [0001] The invention relates to an artificial board and a production method thereof, in particular to an inorganic flame-retardant bamboo-wood composite ecological fiber-planting board and a production method thereof. Background technique [0002] The use of crop straws and inorganic flame-retardant adhesives to produce ecological fiber-planted boards solves the problem of releasing free formaldehyde during the production and use of traditional crop straw-based panels, which is harmful to human health. However, the bonding strength of inorganic flame-retardant adhesives is not as good as that of traditional trialdehyde adhesives. In addition, the fiber content in straw is low and the fiber shape is extremely irregular, resulting in poor fiber performance. The intensity is low. The wood veneer has high fiber content, regular fiber shape, good mechanical properties, and good processability; bamboo veneer has good compressive and bending strength, small shrinka...

AI Technical Summary

Problems solved by technology

However, the bonding strength of inorganic flame-retardant adhesives is not as good as that of traditional trialdehyde adhesives. In addition, the fiber content in straw is low and the fiber shape is extremely irregular, resulting in poor fiber performance. low intensity

The wood 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 splitting, elasticity and toughness. , but there is no wood-based panel made by making full use of the advantages of wood and bamboo in the prior art
