Problems solved by technology

Among them, the marking method involving electrical products is still commonly used today. This method often has problems such as easy abrasion and environmental pollution as described above. The current trend is to use laser marking instead of the commonly used printing method. Influenced by chemicals, etc., it will lead to defects such as unclear laser marks. To solve this problem, the present invention provides a flame-retardant polyester resin composition with laser printing function. The flame-retardant polyester resin composition can be printed on white Laser etched black marks on substrates and laser etched white marks on black substrates

Abstract

The invention discloses a flame-retardant polyester resin composition with a laser marking function. The polyester resin composition adopts polyester resin as the matrix resin, takes a laser marking additive as the laser marking enhancement component, and employs a glass fiber as the performance enhancement component. The polyester resin composition comprises the following components by weight percent: 27-90 of polyester resin, 0-40 of glass fiber, 8-15 of a flame retardant, 0-15 of a toughening agent, 0.3-0.5 of a nucleating agent, 0.2-0.5 of a coupling agent, 0-0.5 of carbon black, 0.2-1 of a laser marking agent, and 0.3-0.5 of an antioxidant. The invention has the advantages that: the laser marking additive is adopted as the laser marking enhancement component and the glass fiber is taken as the performance enhancement component to prepare the resin composition simultaneously having good mechanical properties and laser marking performance. The resin composition can form a white text on a black product surface, or can form a black text and other distinct laser marks on a white product surface.

Description

technical field [0001] The invention relates to a flame-retardant polyester resin composition with a laser marking function and a preparation method thereof, belonging to the field of polymer processing. Background technique [0002] Product marking is becoming more and more important in industry, especially for plastic products, which have a wide range of applications. In production, production dates, bar codes, company slogans, serial numbers, etc. need to be marked frequently. Commonly used marking techniques such as printing, embossing, and stamping are very complicated, requiring skilled staff and a lot of time. Furthermore, it is quite difficult to mark characters or symbols on irregular surfaces. But the importance of non-contact, high-speed laser marking is increasing, especially in plastics, and marking the plastic product itself makes laser marking more durable and abrasion-resistant. In addition, since laser marking does not use solvents, it does not cause envir...
