A microspheric ionomer having a cross-linked structure, a preparation method therefor, applications thereof, and a preparation system thereof. The ionomer comprises structure units A represented by formula (1), structure units B represented by formula (2), and a cross-linking structure provided by a cross-linking agent, M being separately selected from H, a metal cation, and a straight chain, a saturated alkyl of branched or ring-shaped C-C, R being H or a methyl; and metal cations are introduced to part of structure units A in the ionomer. The ionomer shows an outstanding effect on nucleation of PET, serves as a nucleating agent for PET modification, so as to obtain a corresponding PET composition. A system and method for continuously preparing maleic acid ester ionomer microspheres and cross-linked maleic acid ionomer microspheres, so as to achieve continuous preparation, washing and separation of ionomer microspheres, effectively stabilizes the separation effect, and avoids frequent start and stop operations of a centrifuge.

Microspheric ionomer having cross-linked structure, preparation method therefor, applications thereof, and preparation system thereof

The invention relates to a flame-retardant thermoplastic material, comprising thermoplastic base resin, a flame retardant, and an optional antioxidant, wherein the flame retardant comprises a complex of phosphine oxide and a transition metal salt. The invention also relates to flame-retardant thermoplastic expanded beads. A foam molding prepared from the flame-retardant thermoplastic expanded beads has good flame-retardant and antistatic properties, has excellent mechanical properties and is widely used.

Flame-retardant thermoplastic material and expanded beads thereof

The present invention refers to a flame retardant comprising a complex formed by phosphine oxide and transition metal salt, wherein has good flame retardant property. The present invention also refers to a composite flame retardant and flame retardant antistatic composition. The present invention also further refers to a flame resistant method, which adds the abovementioned flame retardant, composite flame retardant or flame retardant antistatic composition into the material, so that said material has flame retardance or flame retardance and antistatic, and has excellent mechanical properties.
