Abstract

The invention discloses a high flame-retardant level halogen-free polycarbonate film material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight, polycarbonate resin, compound halogen-free flame retardants, flame-retardant synergists, modifiers, antioxidants, lubrication dispersing agents, light stabilizers, antistatic agents and the like which are mixed by a high-speed mixer, granulated by a double-screw extruder and prepared into the high flame-retardant level halogen-free polycarbonate film material by a three-roller calendaring sheet extruder. A polycarbonate film made of the material is high in strength, strong in tear resistance, excellent in insulation performance, non-toxic and environmentally friendly, and has 0.3mm V-0 excellent flame resistance.

Description

technical field [0001] The invention relates to a film material, in particular to a high flame-retardant grade halogen-free polycarbonate film material and a preparation method thereof. Background technique [0002] Polycarbonate (PC for short) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester groups, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. It has excellent properties such as colorless transparency, heat resistance, impact resistance, good electrical insulation, and good mechanical strength. It is widely used in daily necessities, electronic appliances, touch screens, insulating sheets, gaskets and many other fields. Although polycarbonate has a certain flame retardancy, it cannot meet the requirements of higher flame retardancy. The flame retardants commonly used in flame retardant polycarbonate and its alloys are mainly brominated flame retardants. Due to the cor...
