Description

TECHNICAL FIELD

[0001] The utility model relates to bubble aluminum heat -insulating blanket production equipment technical field, concretely is a kind of polyimide flame-retardant bubble aluminum heat -insulating blanket production device. BACKGROUND

[0002] Bubble aluminum heat -insulating blanket effectively blocks the transfer of heat by its unique bubble structure, and the aluminum foil layer can reflect heat radiation, while the bubble layer uses the low thermal conductivity of air to effectively insulate radiant heat, thereby playing the role of heat insulation and heat preservation.

[0003] After searching, like patent publication No. CN213291612U, a fireproof heat insulation type bubble aluminum heat insulation blanket is disclosed, which comprises a bubble layer, the inside of the bubble layer is provided with bubbles, the upper and lower surfaces of the bubble layer are fixedly connected with a reinforcing layer, one side of the reinforcing layer away from the bubble layer is provided with an intumescent fire retardant coating, one side of the intumescent fire retardant coating away from the reinforcing layer is provided with a high-purity aluminum foil layer, and one side of the high-purity aluminum foil layer away from the intumescent fire retardant coating is provided with a wear-resistant layer. The outer surface of the wear-resistant layer is provided with transparent fireproof coating. The fireproof heat insulation type bubble aluminum heat insulation blanket improves the overall fireproof effect through the transparent fireproof coating on the surface, prevents fire through the set intumescent fire retardant coating, has strong fireproof ability, improves the overall wear resistance through the set wear-resistant layer, prolongs the service life of the high-purity aluminum foil layer, improves the overall tear resistance through the set reinforcing layer, prevents damage when being pulled, prolongs the service life, and has stable overall structure and is convenient to use.

[0004] In the above-mentioned comparative document, the surface of the bubble aluminum heat insulation blanket is coated with an intumescent fire retardant coating, but in the present situation, polyimide is also coated on the surface of the bubble aluminum heat insulation blanket for flame retardation.
