Abstract

The invention relates to a special material for laser marking injection molding of anti-counterfeiting characters cut in intaglio and a preparation method of the special material. The special material is prepared from raw materials in percentage by mass as follows: 50%-99% of PA6, 0-50% of GF, 0.1%-2% of red phosphorus microcapsules and the balance of other modification aids. Original production procedures and production equipment for plastic products are not changed, and the basic performance of the plastic products is not changed. Rare bar codes of the characters cut in intaglio are automatically formed in the surfaces of the products only in the last laser coding procedure, so that the products are difficult to counterfeit. The special material for injection molding forms codes of the characters cut in intaglio in the surfaces of the formed products. The special material has traceability, exclusiveness and economical property and has a very good anti-counterfeiting property.

Description

technical field [0001] The invention relates to a special plastic material for anti-counterfeit negative laser marking and marking, in particular to a special material for anti-counterfeiting negative laser marking and plastic marking and a preparation method thereof, belonging to the field of plastic modification. Background technique [0002] As a large number of modified plastic products are used in all aspects of industrial products, manufacturers of plastic products have strong anti-counterfeiting requirements. Existing laser coding technology can easily imitate the flat graphics on the barcode, which makes plastic products easy to be counterfeited, which brings huge losses to consumers and manufacturers. The market urgently needs an anti-counterfeiting technology with traceability, exclusivity and economy. The invention provides the market with a retroactive, exclusive and economical special material for anti-counterfeiting and intaglio laser marking on the surface of...
