Embodiment 1

[0044] 5 kilograms of potassium feldspar samples (weight content: SiO 2 ,67%;Al 2 o 3 ,18%;Na 2 O, 3%; K 2 O, 10%; particles 25 microns) mixed with 2.5 kg of sodium hydroxide (weight content: NaOH, 97%; particles 100 microns) were burned at 600° C. for 2 hours. The resulting product was ground into a powder as a solid base activator (7.1 kg; particles ~25 microns). Solid base activator containing SiO 2 and M 2 Molar ratio of O (M is K, Na) to SiO 2 :M 2 O is 1.4:1.

[0045] Blast furnace slag (200-400 order, 60 kilograms), fly ash (containing CaO weight 5.6%, 200-400 order, 20 kilograms), above-mentioned preparation solid alkali activator (5 kilograms), calcium stearate (1kg), Water (48 kg) was mixed at room temperature and stirred for 2 minutes. Obtain adhesive paste.

[0046] After the above-mentioned binder slurry and polystyrene foam particles (1.2 cubic meters, bulk density 7g / L, average particle diameter 1.0-1.5 mm) are fully mixed (2 minutes). Add to mold. ...

Abstract

The invention discloses a geopolymer modified insulation board and discloses a composite insulation board having excellent heat insulation, fire resistance, hydrophobic property and mechanical property. The composition of the insulation board comprises an organic foam particle, a geopolymer binder and a waterproof agent. The geopolymer binder is prepared by reacting an industrial waste, a solid alkali initiator, a waterproof agent and water. The industrial waste is fly ash or blast furnace slag. The solid alkali initiator is a reaction product of potassium feldspar or soda feldspar and potassium hydroxide or sodium hydroxide at a high temperature. The organic foam particle in the insulation board is distributed in the geopolymer binder medium.

Description

technical field [0001] The invention is a geopolymer modified polystyrene insulation board. The insulation board of the invention has excellent heat insulation performance, fire prevention performance, hydrophobic performance and mechanical performance. Background technique [0002] Organic foam materials, such as polystyrene foam, polyurethane foam, and phenolic foam, have been widely used for exterior wall insulation of residential, commercial, and industrial building structures. However, such organic foams exhibit very poor fire resistance even if they contain flame retardancy. Organic foams burn rapidly and produce noxious fumes when exposed to flames. These organic foam materials have caused many fatal fire accidents as exterior wall insulation materials. [0003] Non-combustible insulation boards used as thermal insulation materials for buildings include foam glass, foam ceramics, glass fiber boards, rock wool boards, and foamed concrete, etc. Foam glass and ceramic...
