Abstract

The invention discloses a synergistic flame retardant metal ion treated montmorillonoid PC/ABS (polycarbonate/polyacrylonitrile) alloy material and a preparation method of the alloy material. The alloy material is prepared from the following components by weight percent: (1) 60%-75% of polycarbonate, (2) 5%-25% of ABS (acrylonitrile-butadiene-styrene) resin, (3) 2%-5% of a compatibilizer, (4) 10%-15% of a fire retardant and (5) 1%-5% of metal ion treated montmorillonoid. The alloy material has the advantages that metal ions are replaced to the surface of a sheet layer of the montmorillonoid, so that the problem that metal oxides and metal salt particles are not easily dispersed in polymer materials is well solved; the dispersity of the montmorillonoid in a polymer matrix is improved, so that the contact between the metal ions and the polymer matrix is greatly improved, the synergistic flame retardant effect of the metal ions and the flame retardant is enhanced, and the heat performance and the flame retardant property of polymers are improved.

Description

technical field [0001] The invention relates to processes such as organic synthesis, blending of polymer composite materials, material flame retardancy and mechanical performance testing, that is, the preparation of a metal ion-treated montmorillonite, the compound flame retardant PC of montmorillonite and flame retardant / ABS alloy treatment preparation and performance testing, specifically a metal ion treatment montmorillonite synergistic flame-retardant PC / ABS alloy material and its preparation method. technical background [0002] Polycarbonate (PC for short) is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastic, and is a general term for polymers containing carbonate groups in their molecular chains. PC has excellent physical and mechanical properties, excellent heat resistance and impact resistance, high refractive index, good flame retardant performance, good processing performance, high dimensional sta...
