Abstract

The invention provides a manufacture method of a core material of a vacuum heat insulation plate through aiming at the problem of high cost of the core material of the vacuum heat insulation plate in the prior art. The method comprises the following steps: rock wool fiber pulping and net covering; shaping and rolling; vacuum dehumidifying; and cooling and material forming. The invention adopts the rock wool fiber, and the produced core material of the vacuum heat insulation plate can satisfy performance required by the core material of the vacuum heat insulation plate , and also has the obvious advantages of fire resistance, sound absorption and the like. More importantly, the production process is simple, and the invention can meet the requirement of fast mass production of building industry.

Description

technical field [0001] The invention relates to a method for manufacturing a building material, in particular to a method for manufacturing a core material of a vacuum insulation board for building exterior walls. Background technique [0002] The core material of the vacuum insulation panel generally chooses a porous medium material, such as powdered silica, aerogel, rock wool fiber or microporous polyurethane. The core material has a structural support function to prevent the vacuum insulation panel from shrinking and collapsing under vacuum conditions. The second is to prevent the occurrence of heat radiation, and the third is to reduce the occurrence of heat conduction. Because it is a porous material, the contact area is small, which can effectively reduce the heat dissipation caused by heat conduction. The characteristic that the core material must have is an open-pore structure to facilitate gas evacuation, and the arrangement of the micropores should minimize the str...
