Example Embodiment

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Weigh the raw materials according to the formula of each embodiment in Table 1 below, add the weighed sample into the high-mixer, rotate at 1000 rpm, and mix for 20 minutes. After fully mixing, the premix is ​​obtained. The mixture is transferred to the twin-screw extruder. The extrusion temperature of the twin-screw extruder is: 180°C in the first zone, 190°C in the second zone, 180°C in the third zone, and 170°C in the fourth zone. Rotation speed is 600 rpm, extrusion granulation, granulation 100 ℃ drying 2h, injecti...

Abstract

The invention discloses a modified PA6 material for a laser marker. The modified PA6 material is composed of the following raw materials in parts by weight: 55-85 parts of a PA6 resin, 8-25 parts of nano TiO2, 10-15 parts of an EVA (Ethylene-Vinyl Acetate) resin, 3-10 parts of a flexibilizer POE, 3-7 parts of nano calcium carbonate, 0.1-1 part of a coupling agent and 0.2-0.5 part of a hyperdispersant. The modified PA6 material disclosed by the invention has high laser marking capacity, is high in contrast ratio and clear after marking and has an excellent mechanical property.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a modified PA6 material for laser engraving. Background technique [0002] Laser engraving, also known as laser marking, is to irradiate the surface of the target with laser light, and place text, graphics and symbols, barcodes or images on or under the surface of the target. At present, plastics that have been successfully commercialized with laser marking include acrylonitrile-butadiene-styrene copolymer (ABS) keyboards, high-density polyethylene (HDPE), polypropylene (PP), polyethylene terephthalate (PET) and polyvinyl chloride (PVC) rigid containers and container lids, nylon and polybutylene terephthalate (PBT) automotive and non-automotive electrical connectors, etc. Polyamide 6 (PA6) is a kind of plastic with poor laser marking performance. Generally, even without adding colorants or laser marking aids, PA6 is difficult to mark clearly with laser, so that PA6 m...
