Abstract

The invention relates to a vacuum insulated panel with excellent fireproof performance. The vacuum insulated panel with the excellent fireproof performance comprises a core plate and a high-resistance air film bag. The high-resistance air film bag is mounted outside the core plate in a sealed mode, the core plate comprises a core material and a coating material, the coating material is mounted outside the core material in a sealed mode, the coating material is inorganic cotton felt, the surface density of the inorganic cotton felt is 25-150 g / m<2>, and the content mass fraction of organic glue is 6-25%; and the gross combustion heat valve of the high-resistance air film bag is 2.0-3.9 MJ / m<2>, and the total layer number of thin films forming the high-resistance air film bag is smaller than or equal to six. According to the vacuum insulated panel with the excellent fireproof performance, by controlling the surface density of the inorganic cotton felt, the content of the organic glue, the thickness of the thin films with the heat seal effect and in the high-resistance air film bag, the total layer number of the thin films and the gross combustion heat valve of high-resistance air films, the vacuum insulated panel has the advantages of being excellent in fireproof performance, good in flame-retarding effect, high in stabproof strength, good in heat preservation effect, low in pressing pressure, short in pressing time, not prone to being cracked and short in curing time after mortar coating.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a vacuum insulation panel with excellent fireproof performance. Background technique [0002] At present, the materials used for building exterior wall insulation are divided into A-grade thermal insulation materials and B-grade thermal insulation materials. A-grade thermal insulation materials have good fire performance, but their thermal insulation performance, water resistance, and puncture resistance are lower than B-grade thermal insulation materials, and There are problems such as high price, complicated construction technology and short life. At present, the high-efficiency thermal insulation materials whose combustion performance can reach Class A are mainly inorganic cotton thermal insulation materials, mainly including plate thermal insulation materials of various rock wool, mineral wool, and glass wool products; while B-grade thermal insulation materials hav...
