Description

technical field

[0001] The invention relates to the technical field of laser marking polymer materials, in particular to a halogen-free flame-retardant nylon composite material capable of laser marking and a preparation method thereof. Background technique

[0002] Flame-retardant nylon materials are widely used due to their good mechanical properties, electrical insulation properties and heat resistance, but for the fields of electronics and household appliances, with the improvement of global environmental awareness, flame-retardant nylon materials are required to be halogen-free and non-toxic , environmental protection and flame retardant high efficiency direction. Furthermore, laser marking, as a new generation of precision processing and marking method, has the characteristics of good durability, non-contact processing, high flexibility, and effective anti-counterfeiting. At present, products in the electrical and electronic fields such as relays and capacitors require ...
