Abstract

The invention discloses a manufacturing method for a novel vacuum thermal insulation plate. The manufacturing method comprises the following steps that a heat insulation core material is dried and isarranged in an inner insulation bag; the inner insulation bag is vacuumized and sealed to obtain an inner vacuum thermal insulation plate; the inner vacuum thermal insulation plate is placed between two plate-shaped heat insulation materials to obtain an inner core; the inner core is arranged in an outer insulation bag; and the outer insulation bag is vacuumized and sealed; and the vacuum thermalinsulation plate is obtained after core-and-film-integration treatment. By adopting the manufacturing method for the novel vacuum thermal insulation plate provided by the invention, strength and anti-stabbing performance of the vacuum thermal insulation plate are enhanced; and even if the outer insulation bag is broken accidentally, thermal insulation performance cannot be affected.

Description

technical field [0001] The invention relates to the technical field of thermal insulation of external walls, in particular to a preparation method of a novel vacuum insulation panel. Background technique [0002] At present, building insulation mainly consumes non-renewable resources and produces a large amount of greenhouse gases, thereby damaging the environment. Therefore, taking more effective measures to reduce the heat exchange between buildings and the external environment plays an important role in creating a suitable indoor environment, saving energy and protecting the environment. Traditional building insulation materials, such as mineral wool, foamed plastics, and thermal insulation mortar, have been difficult to fully satisfy people's requirements for building insulation materials such as excellent fire and flame retardancy, strong thermal insulation performance, and small installation volume. aspect requirements. [0003] Vacuum insulation panels are a breakth...
