Problems solved by technology

The polyvinyl chloride film used in the color steel plate and steel belt composite materials inevitably adds a small amount of heavy metal additives in the production process. Finally, it cannot meet the requirements of my country's national standards and EU WEEE & ROSH standards on cupping tests and various shear strength and other performance tests.

Abstract

The invention provides a colored coating and steel plate composite material, wherein steel plate with a coated layer is used as the base plate, the surface of the coating layer is covered by composite polyester film, a polyurethane adhesive layer is arranged between the two materials, the thickness of the coated steel plate is 0.1-2.5mm, the thickness of the polyester film is 10-50um, the thickness of the adhesive layer is 3-30um. The invention also provides the process for preparing the polyurethane adhesive.

Description

technical field [0001] The invention belongs to the technical field of composite materials using steel plates as substrates, and in particular relates to a steel plate film-coated composite material for electrical appliances that meets national standards and EU standards. Background technique [0002] Color-coated composite steel sheet or PSS (Prepainted Steel Sheet) is a commonly used material for the casing of electrical appliances and other electronic equipment. It is also widely used in building wall panels and architectural decoration panels. At present, the common compound-formed color steel plate structure is polyester / polyvinyl chloride / adhesive / steel plate. This composite material can meet the high-strength cupping test and various A weather resistance, fatigue resistance test requirements. [0003] Manufacturers who produce this kind of composite bonding functional material for color-coated steel sheets are Germany's HENKEL Group Company and Japan's Sony (SONY) Ch...
