Fire insulation board

Abstract

The invention discloses a fireproof heat preservation plate. The fireproof heat preservation plate comprises a panel, wherein a fireproof plate is arranged in the panel and is adhered to the panel; a benzene plate is mounted in the fireproof plate, is thinner than the fireproof plate and is connected with the fireproof plate through internal screws; an inner plate is mounted in the benzene plate and is made of a polyethylene material; more than one aluminum plate is vertically mounted in the inner plate; the aluminum plates are uniformly arrayed in the inner plate, and the top and the bottom of each aluminum plate are fixedly connected with the inner plate; a rock wool core layer is arranged between the two aluminum plates close to the inner side of the inner plate and is fixedly connected with the inner plate; reinforcing plates are transversely mounted in the inner plate and penetrate through the aluminum plates and the rock wool core layer respectively. The fireproof heat preservation plate is convenient to mount, the fireproof heat preservation effect is extremely excellent, the compression strength and the tensile strength of the heat preservation plate can be improved, and the heat preservation plate cannot flake or deform when being subjected to external force or temperature change.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a fireproof thermal insulation board. Background technique [0002] With the development of our country's economy, building technology has also made great progress, and people pay more and more attention to the heat preservation and energy saving of buildings. The main wall insulation materials in the early days are mainly thermal insulation mortar, and expanded perlite thermal insulation slurry, composite silicate thermal insulation slurry and rubber powder polystyrene particle thermal insulation slurry are mainly used. Nowadays, rock wool board is a relatively common external wall insulation board. Rock wool is a kind of artificial inorganic fiber made of basalt and melted at high temperature. It has light weight, small thermal conductivity, heat absorption and non-combustibility. It is not only a good thermal insulation material, but also a good fireproof material. It is widely u...
