Abstract

The invention discloses an adhesion enhancement priming paint used for the surface of a gold and silver foil, and a preparation method and an application thereof. The priming paint is composed of a component A and a component B, the component A comprises 70-80wt% of a hydroxy acrylic resin, 15.5-24wt% of a solvent, 3-5wt% of an adhesion promoter, 0.2-0.5wt% of an antifoaming agent and 0.3-0.5wt% of a leveling agent, and the component B comprises 40-45wt% of hexamethylene diisocyanate biuret and 55-60wt% of the solvent. The enhancement priming paint can be dried at normal temperature, and can be coated onto the surfaces of house furnishings or handicrafts or other surfaces plastered with the gold and silver foil after the match with a curing agent to reach extremely-strong adhesion, excellent metal sensation and hot-cold cracking resistance in order to reach excellent decoration and protection purposes.

Description

technical field [0001] The invention relates to an adhesion-enhancing primer for gold and silver foils and a preparation method thereof. Background technique [0002] In recent years, gold and silver foil decoration is favored by high-end hotels, entertainment venues, and rich-class home decoration due to its excellent metallic feeling and high-gloss paint finish, showing luxury and wealth. The products on the market today are directly coated with polyurethane bright surface on the surface of gold and silver foil, which has poor adhesion, and is prone to cracking after cold and heat cycles, which is easy to cause large losses. Contents of the invention [0003] The object of the present invention is to provide an adhesion-enhancing primer for gold and silver foils and its preparation method and application, so as to overcome the above-mentioned defects in the prior art. [0004] The adhesion-enhancing primer for gold and silver foils is composed of component A and compone...
