Abstract

The invention relates to a manufacturing method for a building sheet material which has corrosion-resisting and weather-resisting performances, can prevent dew from dripping off and has a certain heat-preservation performance, and particularly relates to a manufacturing method for a hotly-rolled steel film coated sheet material. The manufacturing method comprises the following steps: selecting materials, pre-treating a sheet surface, carrying out drying treatment, coating an adhesive, coating a film, carrying out a drying procedure, hotly pressing, checking and storing. According to the method, an obtained product has a very good fireproof performance; as being detected, the hotly-rolled steel film coated sheet material obtains the national building material fireproof B-1-grade authentication, is completely environmentally-friendly and has no pollution; the hotly-rolled steel film coated sheet material also obtains the environment-friendly authentication, has the long service life, is environmentally-friendly, has the fireproof, anti-dewing and corrosion-resisting effects, and has the effects of sound absorption, light absorption, heat preservation, high transparency, high glossiness, low haze, excellent ultraviolet light barrier property, laser anti-counterfeiting property and bright decoration effect.

Description

technical field [0001] The invention relates to a method for manufacturing building boards with corrosion resistance, weather resistance, dew condensation prevention, and thermal insulation performance, especially a method for manufacturing hot-rolled steel-coated boards. 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 [0003] The pur...
