Abstract

The invention discloses a manufacturing process of a vacuum heat insulation and preservation plate, and belongs to the technical field of external wall heat preservation materials for buildings. The vacuum heat insulation and preservation plate comprises a core material plate and a protective layer, the protective layer wraps the periphery of the core material plate, and the manufacturing steps comprise manufacturing the core material plate, adding prepared core material plate raw materials into a stirrer, adding water, and conducting stirring to form slurry; feeding a slurry-like core material plate raw material into a forming mold, carrying out extrusion forming to obtain a formed core material plate, obtaining a protective layer consisting of a cement fiber felt and a polyvinyl alcohol film, finally adding a getter into through holes in the core material plate, coating two plate surfaces of the core material plate with a fireproof adhesive, and wrapping the periphery of the core material plate with the protective layer; and conducting extruding by using a roller, conducting drying, polishing and trimming, placing the obtained material in a shade place until complete curing, spraying a waterproof agent and a moisture-proof agent, and conducting sealing and packaging. The problems that in the prior art, an insulation plate is high in manufacturing cost and not high in heat resistance are solved, operation is easy and convenient, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for external walls used in buildings, in particular to a manufacturing process of a vacuum thermal insulation board. Background technique [0002] Wall insulation materials can not only protect the main structure of the wall, but also reduce the influence of external temperature, humidity and various rays on the main structure. [0003] Most of the common vacuum insulation panels on the market are covered with low-alkali bonded mortar, foamed cement, inorganic insulation mortar, modified cement polystyrene particles and other materials. Although this vacuum insulation panel can meet the national standard, the insulation The effect is also good, but there are problems such as high cost and low heat resistance. Contents of the invention [0004] The object of the present invention is to provide a kind of manufacturing technology of vacuum thermal insulation board, to solve th...
