Problems solved by technology

[0006] In the preparation process, the current common ABS / PC alloy materials are usually prepared by a two-step method, that is, the first step is to prepare flame-retardant ABS masterbatch, and the second step is to prepare flame-retardant ABS / PC alloy masterbatch. The two-step production process is due to Power consumption and labor costs are high, so the product cost is high

Abstract

The invention relates to a halogen-free flame-retardant acrylonitrile butadiene styrene (ABS) / polycarbonate (PC) alloy material for electrical engineering and a preparation method thereof. The halogen-free flame-retardant ABS / PC alloy material for electrical engineering comprises the following components in part by weight: 55 to 63 parts of ABS, 21 to 34 parts of PC, 2 to 7 parts of maleic anhydride grafted ABS compatilizer, 7 to 15 parts of organic phosphate flame retardant, 0.1 to 0.5 part of anti-dripping agent FA500B, 1.0 to 3.0 parts of organic silicon Dymgard and 0.2 to 0.5 part of composite antioxidant. In the preparation method, the halogen-free flame-retardant ABS / PC alloy material for electrical engineering is prepared by mixing, plastifying, extruding and pelleting at one step by using a double-single-screw double-step extruder. The comprehensive properties of the product can meet shell performance requirements of storage batteries special for subway engineering, electric locomotives and mobile stations.

Description

technical field [0001] The invention relates to the technical field of a new halogen-free flame-retardant ABS / PC alloy material for electrical engineering, in particular to a halogen-free flame-retardant ABS / PC environmentally friendly alloy material for subway engineering and mobile base station electricity and a preparation method thereof. Background technique [0002] Electric locomotives and subways are special public transportation tools, the safety and technical performance of their components must meet the international environmental protection and flame-retardant technical standards, such as the special battery casing for electric locomotives must meet the US UL94V-0 flame-retardant requirements At the same time, it meets the requirements of the German railway traffic fire test standard DIN5510-2. The flammability level meets the S2 level specified in DIN5510, the smoke level meets the SR2 level specified in DIN5510-2, and the droplet performance level meets DIN5510-2...
