Film-coated aluminum plate for laptop case

Abstract

The invention discloses a film-coated aluminum plate for a laptop case. The film-coated aluminum plate comprises a passivated aluminum substrate, wherein a coating layer and a graphene oxide-water soluble organosilicon modified acrylic resin coating layer are sequentially laminated on the front surface and the back surface of the passivated aluminum substrate; then an adhesive layer, a film-coated layer and a protection coating layer are sequentially laminated on the graphene oxide-water soluble organosilicon modified acrylic resin coating layer which is laminated on the front surface; the coating layer is a film prepared from a chromic acid chemical pretreatment solution; the adhesive layer is prepared from a polyurethane adhesive; the film-coated layer is a PVC (Polyvinyl Chloride) and PET (Polyethylene Terephthalate) composite colorful film. A preparation technology comprises the following steps: coating; drying; coating the graphene oxide-water soluble organosilicon modified acrylic resin coating layer; coating a PET film; coating the protection coating layer. The film-coated aluminum plate disclosed by the invention is good in insulativity and thermal conductivity, higher in hardness, not easy to deform, decolor or degum, and good in protectiveness.

Description

technical field [0001] The invention relates to a film-coated aluminum plate, in particular to a film-coated aluminum plate specially used for a notebook computer / computer casing, and belongs to the field of composite materials. Background technique [0002] At present, most of the ordinary laptop casings are plastic casings. The preparation process is as follows: firstly make a plastic panel of the corresponding size, and then spray paint on the panel to achieve the appearance effect. This kind of plastic casing is complicated to make and has a single color. With the improvement of the requirements for the appearance of notebook computers, this product can no longer meet the needs of customers. Aluminum plate is widely used in production and household appliances due to its low density and easy processing, but its application in high-end products is limited due to its single color and oxidization in the air. [0003] In addition, in order to prevent scratches and damages ca...

[0002] At present, most of the ordinary laptop casings are plastic casings. The preparation process is as follows: firstly make a plastic panel of the corresponding size, and then spray paint on the panel to achieve the appearance effect. This kind of plastic casing is complicated to make and has a single color. The appearance requirements of notebook computers have increased, and this product has been unable to meet customer needs

Aluminum plate is widely used in production and household appliances due to its low density and easy processing, but its application in high-end products is limited due to its single color and oxidization in the air

[0003] In addition, in order to prevent scratches and damages caused by bumps and scratches on the laptop casing, the commonly used solution is to stick a PE protective film on its outer surface, but ordinary PE protective films have many disadvantages: such as insufficient hardness; The adhesive between the protected products is not firm, and it is easy to fall off and the wings at both ends are lifted during use

In addition, the timely heat dissipation capability of a notebook computer is an important limiting factor affecting its service life. In addition to meeting the heat conduction requirements, it also needs to have good insulation performance, and ideal thermal conductivity and insulation performance are usually difficult to meet at the same time.
