Problems solved by technology

However, in the process of laser printing, the existing black PE materials are prone to defects such as blurred marks, poor contrast, and slow marking speed when laser printing is used.
Especially in the printing of small-sized cables with small outer diameter and thin wall thickness, defects such as small marks, blurring, poor contrast, and low marking speed are prone to occur, which cannot meet the needs of industrial production.

preparation example Construction

[0038] The present invention also provides a method for preparing the above-mentioned high-efficiency laser marking material, comprising the following steps:

[0039] A) After mixing HDPE resin and LLDPE resin, add laser auxiliary agent, lubricant, antioxidant, light stabilizer and black masterbatch and mix to obtain a mixture;

[0040] B) extruding and granulating the mixed material to obtain a high-efficiency laser marking material.

[0041] In the present invention, the HDPE resin and the LLDPE resin are first mixed, and the present invention has no special limitation on the mixing method, and the mixing method known to those skilled in the art will suffice. In the present invention, preferably mix according to the following method:

[0042] Put the HDPE resin and LLDPE resin into the batch mixing equipment to reciprocate and mix up and down to obtain the batch mixed resin;

[0043] The batch-mixed resin is placed in a discharge bin, and then automatically weighed, and th...

Abstract

The invention provides a high-efficiency laser marking material. In the formula system of the high-efficiency laser marking material provided by the invention, the addition amount of laser auxiliary agent and black color masterbatch plays a leading role in the printing effect. With the increase of additive content and the decrease of carbon black content, the mechanical properties of the material will not change much, but the printing effect will be significantly improved. In addition, the laser additive can help improve the black PE material to absorb the special wavelength emitted by the laser, so that the surface layer of the polymer is carbonized, and through foaming, it appears white, which is in sharp contrast with the black PE sheath.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a high-efficiency laser marking material and a preparation method thereof. Background technique [0002] In the cable industry, black PE material has been widely used. Black PE materials are generally marked by traditional ink spraying, printing wheel printing, etc., but there are certain limitations and it is difficult to meet production requirements. [0003] Compared with traditional printing methods, laser printing technology is energy-saving and environmentally friendly, with high applicability and clear marks. However, in the process of laser printing, the existing black PE materials are prone to defects such as blurred marks, poor contrast, and slow marking speed when laser printing is used. Especially in the printing of small-sized cables with small outer diameter and thin wall thickness, defects such as small marks, blurring, poor contrast, and low markin...
