Abstract

The invention discloses a hierarchical pore inorganic composite polyphenyl non-combustible thermal insulation material and a preparation method thereof, and relates to the technical field of buildingthermal insulation materials, and the hierarchical pore inorganic composite polyphenyl non-combustible thermal insulation material comprises the following raw materials by weight: 100 parts of a hydraulic silicate gel material, 8-15 parts of hierarchical pore polystyrene foam particles, 0.5-5 part of a flame retardant, 0.5-2 part of hydroxypropyl methyl cellulose, 1-3 parts of a waterproof agent,and a proper amount of water. Inorganic and organic heat preservation materials are compounded, heat insulation and fire prevention are conducted, then the flame retardant, hydroxypropyl methyl cellulose and the waterproof agent are added, the obtained heat preservation material is light in dead weight, small in heat conductivity coefficient, capable of achieving heat insulation and heat preservation and good in strength, and various outer wall non-combustible fireproof heat preservation requirements can be met.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a multi-level porous inorganic composite polystyrene non-combustible thermal insulation material and a preparation method thereof. Background technique [0002] Inorganic composite polystyrene non-combustible insulation board is a class A fire-proof insulation material. It is a homogeneous plate-shaped non-combustible product made of polystyrene foam particles or plates as the insulation matrix and non-magnesite inorganic material treatment agent. In the fire state, it has a certain shape retention ability and does not produce molten dripping, and the combustion performance level reaches Class A. It can be widely used in traditional thin plastering systems and external wall insulation systems of thermal insulation decorative panels. However, the existing inorganic composite polystyrene non-combustible materials on the market have low strength and can...
