Embodiment 1

[0025] Take each component according to the above formula, add it to a high-speed mixer and mix evenly, then use a twin-screw extruder with an aspect ratio of 32-68 to extrude at a speed of 180-500 rpm and a temperature of 180-230°C After granulation, a colorable laser-engraving polypropylene material is obtained, and finally a laser-engraving polypropylene test strip is prepared by an injection molding machine.

Embodiment 2

[0026] The preparation process of Example 2 and Comparative Example 1 is the same as that of Example 1.

[0027] Carry out laser engraving mark test to embodiment 1-2 and comparative example 1, and the test result is specific referring to Table 1 and attached Figure 1-3 .

[0028] The formula of embodiment 1-2 and comparative example 1 and laser engraving mark test result are as shown in table 1:

[0029]

[0030] Table 1: Formulations of Examples 1-2 and Comparative Example 1 and Laser Engraving Marking Test Table

[0031] From Table 1 and in conjunction with the appendix Figure 1-3 As shown, compared with the conventional gray-white laser engraving marks in Comparative Example 1, the laser engraving polypropylene materials of Examples 1-2 exhibited blue and green laser engraving colors, and the colors were more brilliant and visually appealing.

[0032] Carry out material property test to embodiment 1-2 and comparative example 1, the result is as shown in table 2:

Abstract

The invention discloses a polypropylene material capable of being subjected to colored laser carving. The polypropylene material is prepared from the following components in percentage by weight through mixing and extruding: 92 weight percent to 96 weight percent of polypropylene, 1 weight percent to 8 weight percent of laser carving master batch and 0.5 weight percent to 3 weight percent of a coloring agent. The preparation method of the polypropylene material comprises the following steps: after mixing the polypropylene, the laser carving master batch and the coloring agent A or the coloring agent B according to certain weight percent, extruding and granulating by a double-screw extruder at a rotary speed of 180r / min to 500r / min and under the condition that the temperature is 180 DEG C to 230 DEG C; carrying out a laser carving mark test. According to the polypropylene material disclosed by the invention, the coloring agent is used for coloring shallow laser carving and two types of laser carving colors including blue and green are provided; the color richness of laser carving marks is expanded on the basis of keeping basic black of the polypropylene material colored by the laser carving master batch, so that application of a laser carving technology is expanded; higher package requirements are met and the polypropylene material can be directly used as a colored laser carving material, without the need of adding other additives; the polypropylene material is convent to use and has good effect.

Description

technical field [0001] The invention relates to a polymer material, in particular to a polypropylene material capable of color laser engraving and a preparation method thereof, belonging to the technical field of polymer material modification. Background technique [0002] Polypropylene (PP for short) has excellent mechanical properties, excellent bending fatigue resistance, good heat resistance, chemical stability and electrical properties. It is the most widely used general-purpose plastic and is widely used in the plastic packaging industry. [0003] In the plastic packaging industry, laser engraving marking technology is increasingly emerging. In recent years, the use of lasers to engrave and mark the surface of plastic products such as polypropylene has been widely used. The plastic material of granule) is irradiated by laser, which can quickly carry out various pattern markings. Among them, laser engraving polypropylene materials are the most widely used, but laser e...
