Embodiment Construction

[0013] Various embodiments of the present invention provide a method or process for applying an abrasion resistant layer to a plastic automotive window. The automotive window is a multilayer glazing system with a plastic panel, an electroluminescent layer, a weathering layer and an abrasion resistant layer. As discussed further below, the electroluminescent layer can be deposited on the surface of the plastic panel or encapsulated as part of the plastic panel by using a film in-molding (FIM) process.

[0014] figure 1 A partial side view of a car is shown having a plastic car window 100 according to an embodiment of the present invention. Although the plastic automotive window 100 can be placed in various places on the vehicle, it is shown between structural members A and B of the vehicle as shown. The automotive window 100 includes two surfaces, namely, a first surface 10 and a second surface 20 . As used herein, the first surface 10 faces the exterior of the vehicle, whil...

Abstract

A method for applying an abrasion resistant layer (60) via a vacuum deposition technique to a plastic automotive window (100) is provided. The plastic automotive window (100) includes a plastic panel (30), an electroluminescent layer (40), and a weatherable layer (50). A first abrasion resistant sub-layer (63) is then deposed on top of the weatherable layer (50), and a second abrasion resistant sub-layer (66) is then applied onto the first abrasion resistant sub-layer (63). The deposition of the abrasion resistant sub-layers (63, 66) is carried out under controlled temperature conditions that reduce adhesion loss within the electroluminescent layer (40) and maintains the electroluminescent functionality of that layer (40).

Description

technical field [0001] The present invention relates generally to the field of plastic automotive windows. More specifically, it relates to a method for applying an abrasion resistant layer to the inner and / or outer surface of an electroluminescent plastic window. Background technique [0002] In the automotive industry, plastic window systems are beginning to replace traditional glass windows. Because plastic materials exhibit different properties than inorganic (eg, glass) materials, various new processes for the manufacture of these window systems had to be developed. One such method is used to manufacture the Multi-step process for 900 and 900vt plastic glazing systems. The process involves: (1) molding the window from a plastic resin; (2) printing an optional decorative or additional functional (e.g., defroster, etc.) layer using 3-D printing methods; (3) using conventional flow coating , applying a weathering layer by dipping or spraying techniques; and (4) apply...
