Embodiment 1

[0068] Composite material:

[0069] 75g SiC (400 mesh)

[0070] 150g AlSi 2 Kaolin powder (Al 2 (Si 2 o 5 )(OH) 4 )

[0071] ·H 2 O about 100ml. ( * The slurry should have medium viscosity)

[0072] 675g glass spheres (75-100 microns)

[0073] The resulting samples can be cured at room temperature, but stronger ceramic bonds are formed at elevated temperatures, eg by arc-plasma flame surface treatment.

[0074] kaolin (Al 2 (Si 2 o 5 )(OH) 4 ) powder and silicon carbide = 25% H 2The O hydrolyzate was mixed to make a thixotropic polysiloxane ceramic slurry using a silyl silicon emulsion as a binder in the samples. Methylsilane surface primers such as Me 3 SiOH(OH 2 ) 4 , in the case of complex oxide and non-oxide silicate silica interacting with oligomethylsiloxane surfaces, hydrosilylation occurs.

[0075] Surface of solid glass spheres with kaolin (Al 2 (Si 2 o 5 )(OH) 4 ) powder and surface cross-linking of SiC, generating silanol rings, while other m...

Embodiment 2

[0077] Composite material:

[0078] 75g SiC (400 mesh)

[0079] 150g AlSi 2 Kaolin powder (Al 2 (Si 2 o 5 )(OH) 4 )

[0080] ·Solid glass ball (diameter 0.75mm)

[0081] The resulting samples can be cured by induction or vacuum thermoelectric furnaces, where, at elevated temperatures, stronger ceramic bonds are also generated by means of arc-plasma flame surface treatment.

Abstract

Heat insulating panels are widely used in various domains, for example construction sites or hospitals. These panels require adhesives which may generate heat when the panels are subjected to high temperatures. In the field of high temperature insulation, ceramics are brittle and may not be suitable in some applications. This invention discloses a heat-insulating composite including a plurality of glass, and a binder composition for fusing the glass when the heat-insulting composite is exposed to a temperature higher than 1000C. It was found that as the heat progresses from the outer surface to the inner surface of the composite, plurality of laminated ceramic-like structures are formed, which may assist further in insulating the heat. Interestingly, these laminated ceramic-like structures are found to be rubber-like and therefore not brittle.

Description

technical field [0001] The invention relates to the field of thermal insulation materials. In particular, the present invention relates to thermal insulation composites, and more particularly to thermal insulation composites for high temperature insulation. Background technique [0002] Insulation panels are widely used in various fields, such as construction sites or hospitals. Ideally, boards should be lightweight, strong, fire resistant and non-toxic. Traditionally, such panels consist of a lightweight central core structure containing polyurethane foam and polyethylene foam sandwiched between two face sheets. At least one disadvantage of this construction is that the laminate may crack. Further, face sheets can be prone to scratching if not properly adhered to the core structure. This exposes the core structure, which is typically coated with an epoxy-based adhesive to bond the panels. These epoxy-based adhesives are generally flammable and produce toxic substances ...
