Abstract

The invention relates to a manufacturing method of building plates, in particular to a manufacturing method of aluminum alloy coated plates. The building plates are resistant to corrosion and weather proof, prevent dew dropping, and have certain insulation performance. The manufacturing method includes the steps of selecting materials, preprocessing surfaces of plates, drying, coating with glue, laminating, drying, hot-pressing, and checking for storage. The product manufactured by the method has good fire resistance; detections show that the product is approved by the level B-1 of fire rating for national building materials, is fully environment friendly and pollution free, also passes environmental certification, and has the advantages of long service life, environment friendliness, fire proofing, dew prevention, corrosion resistance, acoustic absorption, light absorption, thermal insulation, high transparency, high glossiness, low haze, excellent UV barrier property, laser security, and bright decoration.

Description

technical field [0001] The invention relates to a manufacturing method of a building plate with corrosion resistance, weather resistance, dew condensation prevention, and certain thermal insulation performance, especially a manufacturing method of an aluminum alloy film-coated plate. Background technique [0002] In modern architecture and decoration, in many cases, some metal layers pasted with lining materials are used, such as metal plates pasted with glass fiber or foamed plastics. The advantages of such materials are beautiful, waterproof, and easy to use. Now It has been widely used in large-area construction and decoration such as factories and office buildings. However, the above two commonly used materials also have disadvantages: first, the adhesion fastness is not high, and the lining material on the surface will fall off to a certain extent after about half a year of use; The base material of the lining layer cannot be recycled. Contents of the invention [0...
