Thermoplastic flame-proof filling compositions

Abstract

The invention discloses a thermoplastic flame-retarding filling compound, comprising an A component of 1 to 99%, a B component of 0 to 85%, a C component of 2 to 35%, a D component of 1 to 15%, an E component of 1 to 30% and an F component of 0.05 to 2%. The thermoplastic flame-retarding filling compound is characterized in that: the A component is a graft polymer with an A1 grafted on an A2, and the A1 is a vinyl monomer with a weight percentage of 5 to 95, and A2 is a graft base with a weight percentage of 95 to 5% with vitrification conversion temperature below zero DEG C and an even granularity of 0.20 to 0.40 Mum; the B component is a thermoplastic vinyl copolymer; the C component is a flame retardant; the D component is an assistant flame retardant; the E component is an inorganic compound; the F component is a fluorinated polyolefin. The thermoplastic flame-retarding filling compound has the advantages of reducing the infaust effect to the composition mechanical property from inorganic fillers, and satisfying various specific requirements to flame retardance, dimension stability, mechanical property and specific gravity at particular occasions, just as a stereo set product, a special electronic electric appliance and other occasions.

Description

technical field [0001] The invention relates to the field of flame-retardant modified polymer materials, in particular to a thermoplastic flame-retardant filling composition. Background technique [0002] Flame-retardant modified grafted compositions are widely used in the fields of housings and transmission parts of electronic and electrical products, audio products and other fields due to their various advantages, but the existing such compositions are mechanically The performance decline is obvious, and the composition itself is too selective for the filling material. [0003] CN 1034742A describes a styrene-based polymer based on syndiotactic structure, a mixture of thermoplastic resin and rubber, and a flame retardant, a flame-retardant resin composition of tetrafluoroethylene-based polymer and inorganic filler, but Its mechanical properties are unsatisfactory, and some special engineering plastics are introduced, so the cost performance is not ideal.
