Problems solved by technology

However, vacuum plating this glass fiber reinforced nylon on plastic has poor adhesion properties and poor crack resistance properties
Also, the thin layer of the plated layer is not sufficient to cover substrate defects
Use of a base coat or ultraviolet (UV) coating does not provide optimal adhesion or crack resistance properties

preparation example Construction

[0013] The present invention is a multilayer structure and a method for its preparation. The multilayer structure according to the invention comprises: (a) at least one substrate layer comprising a polymeric material; (b) at least one adhesive layer, wherein the adhesive layer is obtained from an adhesion promoter composition, the adhesive The combined accelerator composition comprises: at least one epoxy resin solution; at least one hardener; optionally at least one leveling agent; at least one toughening agent; at least one filler; a solvent; and (c) at least one surface layer comprising a plated metal; wherein the adhesive layer is located between the at least one substrate layer and the at least one surface layer.

[0014] The substrate layer includes one or more polymeric materials. The polymeric material includes, but is not limited to: polyolefins, such as homopolymers of ethylene or propylene, or copolymers of ethylene or propylene and one or more alpha-olefins; acryl...

Embodiment 1

[0032] The formulation components given in Table I were mixed using a high shear mixer at about 700-1000 rpm for about 30 minutes at 25°C to form Adhesion Promoter Composition 1 of the present invention. With 2mol / l H 2 SO 4 Molded handles made of glass fiber reinforced nylon substrates were pretreated for 1 minute, then washed with water and dried in an oven at 50°C for 2 hours. The Adhesion Promoter Composition 1 was applied to the molded handle by dip coating and then flash dried at room temperature for 5 minutes. The coated molded handle is put into an oven and cured at about 100° C. for 30 minutes; thereby forming an adhesive layer combined with the molded handle, wherein the adhesive layer has a thickness in the range of 20-25 μm thickness. The plated metal is vacuum plated onto the coated / cured surface of the molded handle. The vacuum coating was carried out in a vacuum coating chamber at a coating temperature of 140°C for 15 minutes, wherein the temperature of the ...

Abstract

The instant invention is a multilayer structure, and a method for making the same. The multilayer structure comprises: (a) at least one substrate layer comprising a polymeric material; (b) at least one adhesion layer, wherein said adhesion layer is derived from an adhesion promoter composition comprising: at least one epoxy resin solution; at least one hardening agent; optionally at least one leveling agent; at least one toughening agent; at least one filler; and at least one or more solvents; and (c) at least one surface layer comprising a plating metal; wherein said adhesion layer is disposed therebetween said at least one substrate layer and set at least one surface layer.

Description

technical field [0001] The present invention relates to multilayer structures and methods for their preparation. Background technique [0002] It is known to modify different materials using vacuum plating. Relevant metals for vacuum plating include, but are not limited to: Ti, Ni, Cu, and Cr. Vacuum plating typically provides better adhesion and is more environmentally friendly than conventional plating techniques. However, vacuum plating the glass fiber reinforced nylon on plastic has poor adhesion properties and poor crack resistance properties. Furthermore, the thin layer of the plated layer is not sufficient to cover substrate defects. The use of primer coats or ultraviolet (UV) coatings does not provide optimum adhesion properties or anti-cracking properties. [0003] There is therefore a need for methods of providing vacuum-coated plastic substrates with improved crack resistance and adhesion properties and such vacuum-coated plastic substrates with improved crack...
