Composite board special for heat preservation of building external wall

Abstract

The invention discloses a composite board special for heat preservation of a building external wall and particularly relates to the technical field of heat preservation composite boards. The compositeboard comprises a composite board body. The composite board body comprises a rock wool heat preservation layer, and the rock wool heat preservation layer is provided with a reinforcement thermal insulation assembly. The reinforcement thermal insulation assembly comprises a steel plate, a vacuum layer is arranged in the steel plate, a placement groove is formed in the rock wool heat preservation layer, the steel plate is arranged in the placement grove, and first triangular reinforcement strips are fixedly arranged on the outer side of the steel plate. The composite board is extremely high instructural strength and extremely good in pressure resistance capacity and is prevented from being broken and damaged in the transportation and installation process or damaged due to the external force effect after installation. The vacuum layer is arranged in the steel plate, so that heat transfer is reduced. Since the first triangular reinforcement strips and second triangular reinforcement strips are arrayed in a crossed manner, and the contact point is extremely small, the heat transfer efficiency is further lowered, the excellent thermal insulation and heat preservation effect is achieved, and the installation and fixing effect is also good.

Description

technical field [0001] The invention relates to the technical field of thermal insulation composite boards, and more specifically, the invention relates to a special composite board for thermal insulation of building exterior walls. Background technique [0002] External wall insulation panels are mainly used for walls and roofs of residential, industrial, and public buildings, swimming pools, cold storage, boilers, and some insulation projects that have special requirements for waterproofing. First, it can prevent and reduce temperature deformation of walls and roofs. , can be directly wrapped on the exterior of the building and used for renovation of old buildings. Second, it is conducive to maintaining stable room temperature, reducing solar radiation and outdoor heat from entering the room, and third, improving the air quality of the indoor thermal environment. [0003] The main technical problem in the use of the special composite board for building exterior wall insula...
