Abstract

A method for forming an encapsulation assembly, and a vehicle window are provided. The method includes: providing a reinforcement component; forming a primer layer covering a surface of the reinforcement component; performing a heating treatment on the reinforcement component after the primer layer is formed, to elevate a temperature of the reinforcement component; and injecting a gasket material in a mold onto the surface of the reinforcement component with elevated temperature to form a gasket. The vehicle window includes a glass; and the encapsulation assembly formed by the above method. The gasket may bind with the primer layer more closely. That is to say, binding force between the reinforcement component and the gasket may be increased. In this way, the gasket may not easily detach from the reinforcement component.

First claim

What is claimed is:

1. A method for forming an encapsulation assembly, comprising:
providing a reinforcement component;
forming a primer layer covering a surface of the reinforcement component;
performing a heating treatment on the reinforcement component after the primer layer is formed, to elevate a temperature of the reinforcement component; and
injecting a gasket material in a mold onto the surface of the reinforcement component with elevated temperature to form a gasket;
wherein providing a reinforcement component comprises providing the reinforcement component which has an antirust layer formed thereon; and forming a primer layer covering the surface of the reinforcement component comprises forming the primer layer after forming the antirust layer on the reinforcement component so that the primer layer covers the surface of the reinforcement component which has the antirust layer formed thereon, the primer layer being formed between, and in contact with, the antirust layer and the gasket; wherein the antirust layer comprises epoxy resin;
wherein forming a primer material on the surface of the reinforcement component comprises:
forming a primer material with a water-base solvent which comprises chlorinated polyolefin or polyolefinsilicane; or
forming a primer material with a solvent-base solvent which comprises polyurethane and/or a precursor of polyurethane.

2. The method according to claim 1 , wherein before the primer layer is formed covering the surface of the reinforcement component which has the antirust layer formed thereon, and after the reinforcement component which has the antirust layer formed on the surface thereof is provided, the method further comprises: cleaning a surface of the antirust layer.

3. The method according to claim 1 , wherein the primer layer is formed covering the surface of the reinforcement component by a coating process, a spraying process or a dipping process.

4. The method according to claim 1 , wherein forming a primer layer covering a surface of the reinforcement component comprises:
performing a drying treatment on the primer material to make a solvent in the primer material volatilize to form the primer layer.

5. The method according to claim 4 , wherein performing a drying treatment on the primer material comprises:
laying the reinforcement component aside which has the primer material formed on the surface thereof for a duration ranging from half an hour to forty-eight hours, to make the solvent in the primer material volatilize.

6. The method according to claim 1 , wherein performing a heating treatment on the reinforcement component comprises: elevating the temperature of the reinforcement component to 60° C. to 90° C.

7. The method according to claim 1 , wherein performing a heating treatment on the reinforcement component comprises: heating the reinforcement component which has the primer material formed thereon in a baking oven.

8. The method according to claim 1 , wherein the gasket comprises polyvinyl chloride or thermoplastic elastomer.

9. The method according to claim 1 , wherein the gasket is formed with a groove disposed on a side surface of the gasket, the groove being used to accommodate a piece of glass.

10. The method according to claim 1 , further comprising: fastening a trim to the reinforce component.
