Ultra-light-weight composite environment-friendly fiber board and preparing method of ultra-light-weight composite environment-friendly fiber board

Abstract

The invention discloses an ultra-light-weight composite environment-friendly fiber board and a preparing method of the ultra-light-weight composite environment-friendly fiber board, and belongs to the technical field of an ultra-light-weight fiber board. The ultra-light-weight composite environment-friendly fiber board is characterized by comprising an upper flame-retardant wood fiber layer, a lower flame-retardant wood fiber layer and a wood fiber and expanded perlite mixing layer arranged between the upper and lower flame-retardant wood fiber layers. The invention also discloses the preparing method of the ultra-light-weight composite environment-friendly fiber board. The ultra-light-weight composite environment-friendly fiber board has a series of advantages that the supporting capacity of a high-rise building partition wall is effectively reduced; the strength of the wall surface is enhanced; the properties such as the impact-resistant property, the folding-resistant property and the nail holding force are good; the heat insulation function, the fireproof function, the sound isolation function, the anti-seismic function and the aging-resistant effect are achieved; the secondary wall surface decoration is convenient; and the attaching force of a decoration surface is strong, and the like.

Description

technical field [0001] The invention belongs to the technical field of ultra-light fiberboards, and in particular relates to an ultra-light composite environment-friendly fiberboard and a preparation method thereof. Background technique [0002] At present, the common problems of indoor lightweight partition walls are poor impact resistance, poor nail-holding force on the wall, poor hanging bearing capacity, poor sound insulation effect, general earthquake resistance, waterproof performance and fire limit, and physical and mechanical properties of wallboards. Folding, impact resistance, and poor random cutting. At present, honeycomb paper is mostly used as the core material for wood composite interior doors. The door leaf is deformed, and the cost of the invention is lower than that of wood and hollow particle board, which effectively reduces the production cost of the wood composite interior door and improves the performance and grade of the wood composite interior door.
