Geopolymer based fibreboard

Abstract

The invention discloses a geopolymer based fibreboard which is mainly composed of liquid water glass, aluminosilicate, wood fibers, reinforcement fibers and the like, and also provides a preparation method of the geopolymer based fibreboard. The preparation method comprises the steps of weighing the various raw materials, adding the aluminosilicate, the wood fibers and the reinforcement fibers to a mixer and stirring evenly to obtain a dry powder, adding the liquid water glass to the dry powder which is mixed thoroughly and evenly, and mixing evenly to obtain a slurry, pouring the thoroughly mixed slurry into a fiberboard mold, slicking, and carrying out extrusion forming with pressure of 2.5MPa, maintaining for 6 hours under natural conditions and then demolding, and maintaining under the natural conditions for 7-10 days to obtain the geopolymer based fibreboard. The geopolymer based fibreboard is high in strength, good in water resistant performance, extremely low in water absorbing expansion rate, simple and convenient in maintenance process conditions, good in sound insulation and heat insulation effects, resistant to high temperatures, low in production cost and harmless to the human body; the geopolymer based fibreboard is capable of overcoming the problems of high energy consumption, high maintenance condition requirements and high production cost of the existing material, and also capable of improving the utilization rate of the industrial waste steel slag.

Description

technical field [0001] The invention relates to a geopolymer-based fiberboard, in particular to a geopolymer-based fiberboard using steel slag as a raw material, and belongs to the technical field of building materials. Background technique [0002] Cement fiberboard has been widely used because of its characteristics of fire insulation, waterproof and moisture-proof, heat insulation and sound insulation, light weight and high strength, simple construction, safety and harmlessness, etc. The thin board can be used as a ceiling material and can be perforated as a sound-absorbing ceiling. Body and or decorative materials, thick plates can be used as LOFT steel structure floor panels, attic panels, external wall insulation panels, wall panels, etc. But using cement to produce fiberboard, in order to increase the hardening speed of the board body and improve production efficiency, it is necessary to use rapid hardening cement or add early strength agent, or in the maintenance sta...
