Abstract

The invention relates to the technical field of plastic modification processing, in particular to a flame-retardant synergistic functional master batch special for polyethylene modification and a preparation method thereof. The functional master batch takes multi-composite coated decabromodiphenylethane as a main flame retardant, and the functional master batch comprises the following components by mass percentage: 55.0-70.0 wt.% of multi-composite coated decabromodiphenylethane, 15.0-30.0 wt.% of antimony trioxide, 9.0-13.0 wt.% of an ethylene-octene copolymer, 1.0-2.0 wt.% of styrene-acrylonitrile copolymer coated polytetrafluoroethylene, 0.5-1.0 wt.% of a dispersant, and 0.3-0.5 wt.% of a lubricant. Compared with traditional flame-retardant functional master batch, the functional masterbatch prepared by the invention significantly improves the thermal stability of brominated flame retardants, effectively reduces the material yellowing phenomenon in the thermal machining process, and enhances the flame-retardant effect of domestic brominated flame retardants on polyethylene.

Description

technical field [0001] The invention relates to the technical field of plastic modification processing, in particular to a special flame-retardant and synergistic functional masterbatch for polyethylene modification and a preparation method thereof. Background technique [0002] Polyethylene is a general-purpose plastic with a wide range of applications, and its application covers daily sundries, household appliances, industrial electronic appliances, automobiles, rail transit and other fields. However, the limiting oxygen index of polyethylene is only 17.6 vol.%, which is an extremely flammable polymer material. When polyethylene is used in the fields of electronic appliances and transportation vehicles, flame retardant modification is often required to improve its safety in use. The flame retardant modification of polyethylene can be realized by adding a flame retardant and melt blending through a twin-screw extruder. The flame retardants used are classified according to...
