Abstract

The invention relates to a manufacturing method of building plates, in particular to a manufacturing method of hot-dip galvanized coated plates. The building plates are resistant to corrosion and weather, prevent dropping of dews, and have certain thermal insulating property. The manufacturing method includes the steps of selecting materials, preprocessing the surfaces, drying, coating with glue, laminating, drying, hot-pressing, and checking for storage. Products manufactured by method are well fireproof; detections show that the products are approved by the level B-1 of national building materials fire rating, are fully environment friendly and free of pollution, also pass environmental certification, and have the effects 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 a hot-dip galvanized 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 ...
