Metal-gas heat-insulation plate and method for manufacturing same

Abstract

The invention discloses a metal-gas heat-insulation plate and a method for manufacturing the same. The metal-gas heat-insulation plate is characterized in that an upper metal plate and a lower metal plate are connected with each other in a seal fit manner to form a gas cavity, inflation holes are formed in the walls of the gas cavity, weld positions are arranged at the inner edges of seal edges of the upper metal plate and the lower metal plate, closing strips are arranged between the seal edges of the upper metal plate and the lower metal plate, are positioned on the outer sides of the weld positions and are made of metal with melting points ranging from 90 DEG C to 385 DEG C or alloy of the metal, and the closing strips and the seal edges of the upper metal plate and the lower metal plate are integrally adhered with one another and are sealed. The metal-gas heat-insulation plate and the method have the advantages that high gas tightness of the metal-gas heat-insulation plate can be kept for a long time in severe natural environments, and the metal-gas heat-insulation plate is high in sealing strength and deformation resistance; the molten closing strips with ductility have certain deformation capacity, and accordingly the closing performance still can be perfectly kept when products deform due to factors such as temperature stress, wind load and the dead weight of plate bodies in the severe natural environments.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a metal gas insulation board for external wall insulation and a manufacturing method. Background technique [0002] Existing similar insulation boards mainly include: air insulation boards and fireproof hollow insulation boards. The air insulation board is composed of a core board and a panel compounded on the surface of the core board. The core board is an inorganic viscose corrugated board. A plurality of air insulation chambers are formed between them, and sealing parts are arranged at both ends of the air insulation chambers, so that the air insulation chambers become sealed air insulation chambers. Existence: The corrugated board of the core board connects the upper and lower panels to form a plate-shaped connecting rib, which has a large cold bridge effect and seriously affects the thermal insulation performance of the product. The fireproof hollow insulation board is co...

Problems solved by technology

High cost: The panels and side panels bear the positive and negative wind pressure, self-weight and the weight of the airtight bag and possible collisions behind the insulation board wall. They need to have corresponding strength and rigidity. After the bag is inflated, it must maintain the set shape under the action of the falling force of its own weight. It also needs corresponding strength and rigidity. It must also be well-prepared for anti-corrosion and anti-rust. The material cost and work cost are repeated.

The above two products have not determined how to achieve reliable and long-term sealing, and this is related to whether the product can maintain high air tightness for a long time in harsh natural environments and the key to achieving excellent thermal insulation performance
