Abstract

The invention discloses an aluminum flexible air pipe which comprises an air pipe body, wherein the air pipe body is formed by aluminum foil, and a thermal-insulation layer is coated outside the air pipe body. The thermal-insulation layer is prepared from the following raw materials in parts by mass: 1000-1500 parts of nano bentonite, 1000-1300 parts of vinyl organic silicon resin, 1000-1500 parts of nitrocellulose with the particle size of 5-15 mu m, 800-1200 parts of metallocene linear low density polyethylene, 1200-1800 parts of nano carbon, 35-50 parts of nano calcium carbonate, 10-20 parts of PVC (polyvinyl chloride) resin, 50-80 parts of zinc sulfate, 60-90 parts of bis pentaerythritol and 30-60 parts of polytetrafluoroethylene. The thermal-insulation layer of the aluminum flexible air pipe prepared from the nano bentonite, PVC resin, nano calcium carbonate and zinc sulfate has the advantages of no byproduct, high operability and the like, and effectively controls the production cost. The aluminum flexible air pipe can well dissolve the matched resin; and the nano bentonite in the formula can enhance the thermal-insulation property of the thermal-insulation layer of the aluminum flexible air pipe.

Description

technical field [0001] The invention relates to an aluminum flexible air duct and a manufacturing process thereof. Background technique [0002] In the air-conditioning and ventilation system of rail transit vehicles, the air duct is the transition section connecting the air-conditioning duct and the air outlet. In the past, the air ducts generally used rubber soft air ducts or PE soft air ducts. The defects of this type of air ducts are: poor environmental performance, poisonous, poor thermal insulation performance, short service life, not recyclable, and such ducts are generally straight The tube cannot be bent in any direction and at any angle, which will affect the ventilation volume. Therefore, continuously improving the performance of the aluminum flexible air duct, improving the performance of heat preservation, anti-corrosion, wear resistance, and anti-aging can ensure the protection effect of the air duct. Contents of the invention [0003] The technical problem...
