2. The use of laser texturing as claimed in claim 1 to enhance bonding of metal and bondline surfaces, wherein in step S2 the surface of the top of the metal material is covered in sequence with a bondline and other layers of material.
3. Use of laser texturing as claimed in claim 1 to enhance the bonding of metal to the surface of a glue layer, wherein the glue layer is POE plastic or polyurethane glue film.
4. The use of laser texturing as claimed in claim 1 to enhance the bonding of metal and bondline surfaces, wherein in step S3 the vacuum lamination is carried out at a temperature of 80-170 ℃.
5. The use of laser texturing as claimed in claim 1 to enhance bonding of metal and bondline surfaces, wherein in step S3, the vacuum lamination is for a period of time of 50 to 600S.
6. The use of laser texturing as claimed in claim 1 to enhance the bonding of metal and bondline surfaces, wherein in step S3, the laminate is vacuum laminated and then left at room temperature for more than 4 hours.
7. The use of laser texturing as claimed in claim 1 to enhance the bonding of metal and bondline surfaces, wherein in step S3 the vacuum lamination is carried out at a pressure of 0.1-0.3MPa.
8. The use of laser texturing as claimed in claim 1 to enhance bonding of metal and bondline surfaces, wherein said other material layer is polyvinylidene fluoride or ink glass.
