Document Type and Number:
WIPO Patent Application WO/2021/036899
Kind Code:
A1
Abstract:
Provided are a complex capable of achieving low-temperature laser marking of multiple colors and a preparation method therefor. The complex comprises the following components in parts by weight: 100 parts of a polymer, 0.1-1 part of a thermally conductive additive, 1-3 parts of a heat-sensitive additive, 0.1-1 parts of a chromogenic reagent, and 0.1-2 parts of an organic pigment. The preparation method comprises: mixing the raw materials in proportion for melt extrusion and granulation; then performing melt extrusion or injection molding to form a plastic product; and next, performing laser marking on the surface of the plastic product by a laser pulse, and controlling, by laser energy, the laser marking temperatures on the plastic surface to obtain marks of various colors. The addition of a heat-sensitive additive and a chromogenic reagent enables the material to achieve low-temperature laser marking of multiple colors by laser pulses, the effect is special, the process is simple, and the invention can be used for product appearance decoration and has a good market application prospect.
