Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a laser-markable glass fiber-reinforced black polyamide composition, which can overcome the fact that black polyamide is difficult to carry out laser marking due to the presence of glass fibers and that most of the current laser fillers are The physical and mechanical properties of the material caused by inorganic substances, and the light transmittance decrease

Embodiment 1～6

[0034] Nylon 66 (viscosity 3.2, Pingdingshan Shenma Engineering Plastics Company), carbon black (Germany, Cabot, M470), melamine cyanurate blowing agent (MelapurMC50, Ciba, Switzerland) and a small amount of antioxidant 1010 (Ciba, Switzerland) Company) placed in a high-speed mixer for physical blending, stirring evenly; put the mixture into a twin-screw extruder (Germany WP company, model ZSK-25) for melt blending and extrusion, and at the same time add Alkali-free glass fiber, the extrusion temperature is 255°C-270°C, and the screw speed is 300rpm. The extruded pellets were dried in an oven at 100°C for 8 hours, and then injected into standard specimens at a temperature of 255°C to 265°C for laser marking performance tests and related performance tests. The specific formula is shown in Table 1, wherein the contents of each component are calculated in parts by weight. The performance results are shown in Table 1 and Table 2.

Abstract

The invention relates to a daiamid composition capable of being marked by laser. The daiamid composition comprises the following blended components: 100 parts by weight of daiamid, 1-10 parts by weight of melamine cyanurate, 0.01-1 part by weight of carbon black, and 10-60 parts by weight of glass fiber. The invention also relates to a method for preparing the daiamid composition capable of being marked by laser. The method is characterized in that the daiamid composition capable of being marked by laser is prepared by melting and blending daiamid, the melamine cyanurate, the carbon black and the glass fiber. The composition can overcome the problems that the black daiamid is difficult to be marked by laser due to the existence of glass fiber, and the physical and mechanical property and transmittance of material are reduced as the most current laser fillers are inorganic substances.

Description

technical field [0001] The invention relates to a laser-markable polyamide composition and a preparation method thereof, in particular to a glass fiber-reinforced polyamide composition capable of forming light-color printed marks on a dark background and a preparation method thereof. Background technique [0002] Labeling on produced items is becoming increasingly important in almost all industrial sectors. For example, it is often necessary to indicate the production date, expiration date, barcode, company's trademark, serial number, etc. on the item. [0003] At present, there are many technical methods for printing marks on objects, such as screen printing and transfer printing, embossing, embossing, ink printing, etc. are all well-known printing technologies. These printing methods are surface printing, which means that the resulting identification mark becomes difficult to read due to mechanical damage, friction, chemical action and the like, and this printing method i...
