preparation example Construction

[0077] As the preparation method of MBS resin, it can carry out by various methods, such as bulk polymerization, suspension polymerization, and emulsion polymerization, for example. Especially preferred is the emulsion polymerization method. The thus obtained core-shell graft rubbery elastomer preferably contains 50% by weight or more of the aforementioned rubber component. The content of the unsaturated alkyl carboxylate-diene rubber-aromatic vinyl graft copolymer (component F) is preferably 0.1 to 10 parts by weight based on 100 parts by weight of the total of components A and B , more preferably 0.5 to 7 parts by weight, even more preferably 1 to 5 parts by weight.

[0078] Examples of commercially available MBS resins include Metabren C-223A (trade name, manufactured by Mitsubishi Rayon Co., Ltd.), Pararoid EXL-2638 (trade name, manufactured by Rom & Haus Co., Ltd.), and the like.

[0166] With the composition shown in Table 1, a mixture containing the components of the ABS resin other than the C component, the B component, and the B component was supplied from the first supply port of the extruder. The mixture is obtained by mixing the premix of (i) and other ingredients with a V-type mixer. That is, (i) is a mixture of component D (fluorine-containing anti-dripping agent) and aromatic polycarbonate of component A, and is a mixture in which component D is 2.5% by weight by vibrating the entire bag in a polyethylene bag. Component B and ABS resins other than component B were supplied from the second supply port using a side feeder. Further, FR of component C was heated to 80°C from the third supply port (located between the second supply port and the discharge port) in the middle of the cylinder using a liquid injection device (HYM-JS-08 manufactured by Fuji Techno Industry Co., Ltd.). Between the gas ports) to the extruder to achieve the specified ratio...

Abstract

The invention provides a flame retardant aromatic series panlite polycarbonate resin composite, wherein, as per parts by weight, the composite contains 50-90 parts by weight of aromatic series panlite polycarbonate resin (component A) and 1-50 parts by weight of thermoplastic graft copolymer (component B), which is formed by grafting vinylcyanide compounds and aromatic series vinyl-compounds on dienes rubber constituent, and does not present an absorption peak derived from fatty amide between 3200cm<-1> and 3400cm<-1> in the measurement of infrared absorption spectrum, and the rubber constituent content of which is 5-80 percent by weight, and contains 1-30 parts by weight of organophosphorous flame retardant (component C) and 0.05-2 parts by weight of fluorine-containing drip-proof agent (component D) as well, and all the contents of the composite amount to 100 parts by weight. The invention also relates to a flame retardance aromatic series panlite polycarbonate resin composite which contains aromatic series panlite polycarbonate resin, ABS resin, organophosphorous flame retardant and fluorine-containing drip-proof agent and the flame retardance of which is further improved without reducing flowability and mechanical features.

Description

technical field [0001] The present invention relates to containing aromatic polycarbonate resin, ABS resin, organophosphorous flame retardant, fluorine-containing anti-dripping agent (containing フツ A flame-retardant resin composition having improved flame retardancy of a dripping preventive agent. More specifically, the present invention relates to a resin composition in which flame retardancy is further improved without lowering fluidity and mechanical properties by blending a specific ABS resin. Background technique [0002] Aromatic polycarbonate resins are widely used in industry due to their excellent mechanical and thermal properties. However, aromatic polycarbonate resin has the disadvantages of poor moldability due to its high melt viscosity and poor fluidity. In order to improve the fluidity of aromatic polycarbonate resins, a large number of polymer alloys with other thermoplastic resins have been developed. Among them, polymer alloys with ABS resins are widely...
