Abstract

The invention relates to a building outer wall fire-proof heat-insulating material and a preparation method thereof. The building outer wall fire-proof heat-insulating material is characterized by comprising a low-heat conduction fire-proof gelling material and a polystyrene foaming granule; per-cube weight ratio of low-heat conduction fire-proof gelling material to polystyrene foaming granule is (180-230):(6-10), wherein the low-heat conduction fire-proof gelling material contained in per-cube heat-insulating material comprises the following raw materials by weight: 50-90 kilograms of water glass, 50-75 kilograms of slag, 25-35 kilograms of coal ash, 25-35 kilograms of steel slag, 0.1-0.5 kilogram of fibers, 1.0-3.0 kilograms of redispersible latex powder, 1.0-3.5 kilograms of foam stabilizers, 2-10 kilograms of foaming agents and 2-10 kilograms of water. The building outer wall fire-proof heat-insulating material disclosed by the invention has the advantages of excellent fire-proof capacity, lower heat conductivity coefficient and higher strength.

Description

1. Technical Field [0001] The invention relates to a fireproof and thermal insulation material and a preparation method thereof, in particular to a fireproof and thermal insulation material for building exterior walls and a preparation method thereof. 2. Background technology [0002] It is a common practice for buildings to save energy and reduce consumption by doing external insulation on the exterior wall of the building to enclose the entire building to reduce energy consumption. At present, the thermal insulation materials that can apply this approach on the market usually include organic EPS, XPS, PU, ​​phenolic, inorganic rock wool, and inorganic porous thermal insulation materials. Organic thermal insulation materials have good thermal insulation ability, light weight and convenient construction, but these materials are prone to fires. In recent years, a series of major fires have been caused by external thermal insulation materials for external walls, and their use has a...
