Abstract

The invention discloses a composite material of a heat insulation and sound insulation aerogel layer composite breathable membrane and a manufacturing method thereof. The composite material comprises a breathable membrane layer, a bonding connection layer and an aerogel layer, wherein the breathable membrane layer and the aerogel layer are bonded through the bonding connection layer. The manufacturing method of the composite material comprises the steps of performing process preparation, unreeling the breathable membrane, coating the breathable membrane with the bonding connection layer in a rolling way; laying aerogel; spraying and coating the bonding connection layer on the aerogel layer; covering the aerogel layer with the breathable membrane; performing heating rolling pressing and curing; performing rolling. The composite material has the advantages that the flexibility is high; frost crack cannot occur in an environment from the extremely low temperature of -268 DEG C to the temperature of 300 DEG C; the composite material can be widely applied to occasions with requirements of long service life, corrosion protection, outdoor ultraviolet environment aging resistance, heat insulation protection and strong sound isolation.

Description

technical field [0001] The invention relates to the technical field of heat insulation and sound insulation, in particular to a composite material of a heat insulation and sound insulation airgel layer composite breathable membrane and a manufacturing method thereof. Background technique [0002] A large number of thermal insulation materials currently in use are inorganic fireproof thermal insulation mortar, foam glass, glass wool, rock wool, polystyrene foam and polyurethane foam. The thermal insulation effect of the above materials is general; Glue is the main material, and it is compounded in reinforcing fibers, such as glass fiber, pre-oxidized fiber, and a flexible thermal insulation material synthesized by a special process. At present, airgel blankets are used in a narrow temperature range of 400°C, and the performance of airgel has not been fully utilized. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provid...
