Embodiment 1

[0028] At room temperature, the fumed silica powder and glass fiber are placed in a vibrator with a mass ratio of 9:1, and after 30 minutes of vibration in the equipment, the surface of the powder particles reaches a mechanically molten state, adsorbed on the well-dispersed On the single fiber, so that the powder fully wraps the glass fiber to form a sandwich structure. Then put the mixture into a square mold with a size of 500mm×500mm, apply a pressure of 0.5MPa, and keep the pressure for 4 hours to make it into shape. A new type of composite wallboard with high efficiency, light weight, heat insulation and fire prevention at the nanoscale can be obtained by opening the mold, such as figure 1 shown.

Embodiment 2

[0030] At room temperature, take 75 parts of fumed silica powder, 15 parts of silica airgel powder, and 10 parts of high-silica fiber and place them in a vibrator, and vibrate in the equipment for 30 minutes to make the surface of the powder particles It reaches a mechanical melting state and is adsorbed on the dispersed single fiber, so that the powder fully wraps the high-silica fiber to form a sandwich structure. Then put the mixture into a square mold with a size of 500mm×500mm, apply a pressure of 1MPa, and keep the pressure for 4 hours to make it into shape. A new type of composite wallboard with high efficiency, light weight, heat insulation and fire prevention at the nanoscale can be obtained by opening the mold.

Embodiment 3

[0032] At room temperature, take 55 parts of fumed silica powder, 35 parts of silica airgel powder, and 10 parts of ceramic fiber in the vibrator, and vibrate in the equipment for 30 minutes to make the surface of the powder particles reach a certain level. It is in a state of mechanical melting and adsorbed on the dispersed single fiber, so that the powder fully wraps the ceramic fiber to form a sandwich structure. Then put the mixture into a square mold with a size of 500mm×500mm, apply a pressure of 2MPa, and keep the pressure for 4 hours to make it shaped. A new type of composite wallboard with high efficiency, light weight, heat insulation and fire prevention at the nanoscale can be obtained by opening the mold.

Abstract

The invention provides a nanoscale efficient heat-insulated fire-proof light-weight composite wall plate as well as preparation and construction methods thereof and belongs to the field of heat-insulated materials of buildings. The invention belongs to a composite material and particularly relates to an efficient heat-insulated fireproof composite plate which is formed by mainly and effectively combining nanoscale silicon dioxide, aero gel, fibre glass, high silica fibers and the like. The nanoscale efficient heat-insulated wall plate has the advantages of high strength, low heat conductivity coefficient which is less than 0.025W / mk, good heat insulation effect, incombustible performance, ageing resistance, light weight and small density which is less than 280kg / m<3>; and the preparation method is simple and convenient, is convenient in processing, and easy for realization of large-scale production.

Description

technical field [0001] The invention relates to a thermal insulation wallboard, in particular to a light-weight thermal insulation composite wallboard with high efficiency, heat insulation and fire prevention. The utility model belongs to the field of thermal insulation materials for buildings. Background technique [0002] At present, energy resources are becoming increasingly tense, and energy shortage is a reality in today's world and a common problem faced by global development. Conserving energy has become the basic national policy of building a conservation-oriented society and taking the road of sustainable development in our country. The number of existing buildings in our country is huge. There are about 40 billion square meters in the country, of which about 13 billion square meters are in cities and towns. And it is still growing rapidly at a scale of hundreds of millions every year. Among the existing buildings, 99% are non-energy-saving buildings, and the pro...
