Abstract

The invention provides a highlight extrusion halogen-free flame-retardant PC / ABS alloy material and a preparation method thereof, and an obtained product, and belongs to the technical field of high polymer materials. The highlight extrusion halogen-free flame-retardant PC / ABS alloy material is composed of the following components in percentage by weight: 70-83% of polycarbonate, 5-20% of ABS, 8-15% of a flame retardant, 2-5% of an interface toughening compatilizer, 0.1-0.5% of a PTFE anti-dripping agent, 1-10% of a flame-retardant synergist, 0.1-0.5% of a lubricant and 0.1-0.5% of an antioxidant. The alloy material has good mechanical properties, impact strength and saturability and good gloss and flame retardance, and a product prepared from the alloy material is full and uniform in thickness and can be effectively used for preparing outdoor power grid wire ducts, so that the alloy material has a wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-gloss extruded halogen-free flame-retardant PC / ABS alloy material, a preparation method thereof, and a product obtained therefrom. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. ABS resin is a terpolymer (acrylonitrile-butadiene-styrene) developed on the basis of polystyrene (PS) resin modification. It is a kind of good performance between engineering plastics and general-purpose plastics. Thermoplastic resin with comprehensive properties and easy processing. PC / ABS alloy has the advantages of non-toxic, odorless, renewable, and superior comprehensive performance. With the development of technology, the market puts forward more r...
