Problems solved by technology

[0004] Since the conventional epoxy fiberglass cloth laminates are three colors of natural color, yellow and black, for the laser technology, the epoxy glass fiber cloth laminates of these three colors cannot meet the clear requirements of the QR code
Therefore, there is a white epoxy fiberglass cloth laminate on the market. The white epoxy fiberglass cloth laminate on the market is printed on the ordinary natural color epoxy fiberglass cloth laminate to achieve a white surface. As a result, the cost increases, the product thickness is difficult to control, the white ink is burned by the laser at high temperature during the laser coding process, and the pattern formed by laser coding changes color or even deforms, resulting in the recognition level of scanning two-dimensional codes being BC level, the minimum The size is 3mm*3mm, which cannot meet the requirements of high recognition and small size of QR codes

Abstract

The invention discloses a white epoxy glass fabric laminated board printed with two-dimensional codes by laser and a laminating process, and belongs to the technical field of epoxy glass fabric laminated boards, the white epoxy glass fabric laminated board comprises an epoxy glass fabric laminated board body and a laser printing layer, the laser printing layer is bonded on the side wall of the epoxy glass fabric laminated board body, and the laser printing layer is bonded on the side wall of the epoxy glass fabric laminated board body. The epoxy glass fiber cloth laminated board body is formedby overlapping a plurality of structural unit layers, each structural unit layer comprises epoxy glass fiber cloth, a PP film and a yellow resin layer, and yellow resin layers are bonded on the innersurface layer and the outer surface layer of the epoxy glass fiber cloth through PP films. Single-sided high-temperature resistance, friction resistance and difficulty in burning of the epoxy glass fiber cloth laminated board are improved by blending the color and components of resins, a pattern formed by laser coding is difficult to discolor, good in smoothness and high in definition, the recognition level reaches the A level, the minimum size can reach 1mm * 1mm, the cost is reduced, the thickness is convenient to control, and traceable management is performed on a product.

Description

technical field [0001] The invention relates to the technical field of epoxy fiberglass cloth laminates, in particular to a white epoxy glass fiber cloth laminate and a lamination process with laser-printed two-dimensional codes. Background technique [0002] Epoxy resin has become a common material not only in daily life but also in national defense technology due to its light weight, high strength, good corrosion resistance, good electrical insulation performance, easy processing and molding, wide source of production raw materials, and high cost performance. . As a kind of epoxy resin material reinforced by glass fiber modification, epoxy fiberglass cloth laminate has been more widely used due to its better mechanical properties, insulation properties and good processing. At present, epoxy fiberglass cloth laminates are mainly used in electronic products, vehicles, construction and other fields. [0003] However, due to the rapid development of electronic product techno...
