Problems solved by technology

[0002] At present, building energy-saving standards are getting higher and higher, and at the same time, higher requirements are put forward for the technical performance of building materials. There is a phenomenon of mixed fish in the external wall insulation market, and a large number of materials that cannot meet fire protection requirements or thermal insulation functions are still in use. For example, most organic materials cannot achieve the real B1 level, while the thermal insulation performance and water absorption of inorganic materials are greatly reduced, some such as airgel are expensive, and the operation of vacuum insulation panels is difficult. material imminent

Abstract

The invention relates to the technical field of outer wall glass wool boards, and particularly relates to a low-thermal-conductivity outer wall glass wool board and a production process thereof. The low-thermal-conductivity outer wall glass wool board comprises vertical glass wool, wherein slurry is injected into gaps of the vertical glass wool through a permeation process, and gridding cloth is arranged on the upper end face and the lower end face of the vertical glass wool respectively. According to the low-thermal-conductivity outer wall glass wool board, the fire resistance can be improved, and fire hazards caused by buildings are reduced; the thermal insulation performance can be improved, and the damage to the original structure due to high water absorption of part of materials is reduced, so that the thermal insulation effect is improved; meanwhile, the low-thermal-conductivity outer wall glass wool board is high in strength, and then the risk of falling off during external hanging is reduced.
