Abstract

The invention relates to the technical field of plastic modification processing, in particular to halogen-free flame-retardant synergistic functional masterbatch special for polyphenyl ether modification and a preparation method thereof. According to the functional masterbatch, multiply composited coated red phosphorus is used as a phosphorus flame retardant; and the functional masterbatch is prepared from the following components in percentage by mass: 70.0 wt.%-80.0 wt.% of the multiply composited coated red phosphorus, 3.0 wt.%-5.0 wt.% of organic phosphate, 17.0 wt.%-25.0 wt.% of an ethylene-methyl acrylate copolymer, 0.5 wt.%-1.0 wt.% of a dispersing agent and 0.3 wt.%-0.5 wt.% of a lubricating agent. Compared with the traditional flame-retardant functional masterbatch, the functionalmasterbatch prepared by the method has the advantages that thermal stability and water resistance of red phosphorus are remarkably enhanced, the activity of red phosphorus and the corrosion of red phosphorus to a base material are reduced, and the compatibility with a resin matrix is improved, so that the flame-retardant effect of red phosphorus to polyphenyl ether is more effectively improved.

Description

technical field [0001] The invention relates to the technical field of plastic modification processing, in particular to a special halogen-free flame retardant synergistic functional masterbatch for polyphenylene ether modification and a preparation method thereof. Background technique [0002] Polyphenylene ether is an engineering plastic with excellent dielectric and electrical insulation properties, which is widely used in the fields of industry and household electronic appliances. When polyphenylene ether is used to manufacture electronic and electrical components or related peripheral equipment, it is often necessary to implement flame retardant modification to improve its safety in use. The flame retardant modification of polyphenylene ether can be realized by adding a flame retardant and melt blending through a twin-screw extruder. Flame retardants can prevent polyphenylene ether from being ignited and inhibit flame propagation, which can effectively improve the comb...
