The present invention relates to a flame-retardant thermoplastic resin composition having excellent impact resistance, heat resistance, weather resistance, and moldability. In order for plastic materials to be used in a variety of fields as engineering plastics such as automobile parts, electrical parts, building materials, and industrial parts, they must have properties such as impact resistance, heat resistance, weather resistance, and easy moldability. There must be. However, although various thermoplastic resin compositions that are excellent in each of these properties are known, a resin composition that satisfies all of these properties has not yet been found. In view of the current situation, the present inventors conducted various studies in order to obtain a thermoplastic resin composition with excellent impact resistance, heat resistance, weather resistance, and moldability. It was discovered that a thermoplastic resin composition consisting of a copolymer, a styrene resin, and an aromatic polycarbonate resin had the desired performance, and a patent application was previously filed. By the way, synthetic resins, like the above-mentioned thermoplastic resin compositions, are generally flammable, and their uses are limited from the standpoint of safety. For example, resin compositions used in electrical parts and building materials are required to have high flame retardancy as shown in UL standards. Conventionally, it has been known to add halogen-containing compounds, phosphorus-containing compounds, or a combination of these compounds to make synthetic resins flame retardant, but even if the purpose of flame retardation is achieved, the original properties of the synthetic resin There are various drawbacks such as a significant decrease in physical properties, problems with compatibility with the synthetic resin used, and a tendency to cause poor workability such as sublimation and odor during molding. Based on the current situation, the present inventors conducted various studies in order to further improve the properties of flame-retardant thermoplastic resin compositions, and found that for thermoplastic resin compositions containing aromatic polycarbonate resin as one component, 2,2 with a specific melting temperature as a flame retardant
Excellent impact resistance achieved by blending a condensation polymer of (4,4'dihydroxy-3,3',5,5'-tetrabromidiphenyl)propane and antimony trioxide as a flame retardant aid. The present inventors have discovered that a flame-retardant thermoplastic resin composition can be produced which provides a high degree of flame retardancy in addition to heat resistance, weather resistance, and moldability, and has thus arrived at the present invention. That is, the gist of the present invention is to provide an aromatic vinyl copolymer obtained by copolymerizing a vinyl copolymer containing an acrylic rubber component and a monomer mixture containing an aromatic vinyl monomer as a main component. 2,2(4,4'dihydroxy-3,3',5,5'-
Condensation polymer of tetrabromodiphenyl)propane
B3 to 25 parts by weight and antimony trioxide C are 10/1 to 1/1 in weight ratio (B/C) of B component and C component
The flame retardant thermoplastic resin composition is formulated in the following proportions. The vinyl copolymer containing the acrylic rubber component used in the present invention is obtained by polymerizing acrylic ester monomers such as ethyl acrylate, butyl acrylate, and 2-ethylhexyl acrylate as the main monomer component. Copolymerizable at least one vinyl compound consisting of an acrylic ester monomer, a methacrylic ester monomer, a vinyl cyanide monomer, an aromatic vinyl monomer, etc. in the presence of a rubbery polymer. It is a copolymer obtained by polymerizing monomers. The copolymer can be produced by any method such as bulk polymerization, suspension polymerization, emulsion polymerization, etc., or a combination thereof. In the present invention, the vinyl copolymer containing the acrylic rubber component preferably has a graft structure in which the acrylic rubber component and the vinyl polymer form a graft structure. A mixture of monomers such as methyl methacrylate, acrylonitrile, and styrene is mixed with a suitable initiator in the presence of a copolymer rubber latex which is obtained by copolymerizing butyl acrylate with styrene, acrylonitrile, or methyl methacrylate. A method of coagulating and drying a latex obtained by emulsion polymerization using the above method is mentioned. An example of the vinyl copolymer containing the acrylic rubber component in the present invention is obtained by polymerizing an acrylic ester monomer having 2 to 10 carbon atoms in the alkyl group as a main component. Ethyl acrylate, butyl acrylate, acrylic acid 2 in the presence of 25 to 90 parts by weight of rubbery polymer.
Acrylic acid ester monomers such as ethylhexyl,
At least one vinyl compound such as a methacrylic acid ester monomer such as methyl methacrylate, a vinyl cyanide monomer such as acrylonitrile or methacrylonitrile, and an aromatic vinyl monomer such as styrene or α-methylstyrene. Examples include resin polymers containing an acrylic rubber component obtained by polymerization of ~10 parts by weight. The amount of the vinyl copolymer containing the acrylic rubber component used in the present invention is 5 to 50% by weight in the thermoplastic resin composition A. The aromatic vinyl copolymer used in the present invention is mainly composed of aromatic vinyl monomers such as styrene, α-methylstyrene, trimethylstyrene, and halogenated styrene, and also has an acrylic acid copolymerizable with these monomers. Copolymerizing a monomer mixture with at least one vinyl monomer selected from the group of acid ester monomers, methacrylic acid ester monomers, vinyl cyanide monomers, aromatic vinyl monomers, etc. It is obtained by doing. Examples of copolymerizable acrylic ester monomers include ethyl acrylate, butyl acrylate, and 2-ethylhexyl acrylate. Examples of the methacrylic acid ester monomer include methyl methacrylate and ethyl methacrylate. Examples of the anionized vinyl monomer include acrylonitrile and methacrylonitrile. Furthermore, aromatic vinyl monomers include styrene, α-methylstyrene, trimethylstyrene,
Examples include halogenated styrene. In the present invention, styrene-acrylonitrile copolymer is particularly preferred. The aromatic vinyl copolymer in the present invention can be produced by any method such as bulk polymerization, suspension polymerization, emulsion polymerization, or a combination thereof. In the present invention, the amount of the aromatic vinyl copolymer obtained by copolymerizing the monomer mixture containing aromatic vinyl monomer as the main component is 5 to 80% by weight in the thermoplastic resin composition A. be. The aromatic polycarbonate resin used in the present invention is a 4,4'-dioxydiarylalkane-based polycarbonate resin, and a typical example is a carbonate resin of 2,2'(4,4-dihydroxydiphenyl)propane. Can be mentioned.
As a method for producing the aromatic polycarbonate resin, any known method such as the phosgene method or the transesterification method can be used. The amount of aromatic polycarbonate resin in thermoplastic resin composition A in the present invention is 15 to 80% by weight. When the usage amount of each resin component constituting the thermoplastic resin composition A used in the present invention is within the usage amount range as described above, mutual interaction with the flame retardant and flame retardant aid described below. It is particularly preferred because it exhibits excellent effects. 2,2 used as flame retardant of the present invention
(4,4'dihydroxy-3,3',5,5'-tetrabromidiphenyl)propane condensation polymer (hereinafter abbreviated as brominated polycarbonate). is a general expression This is shown in . In the formula, R and R' are terminal residues of phenols, and n indicates the average degree of polymerization. n
A value of 2 to 60 is preferable. The brominated polycarbonate used in carrying out the present invention has a melting temperature in the range of 140 to 190°C, preferably in the range of 160 to 170°C. It is not preferable to use a brominated polycarbonate having a melting temperature of less than 140° C. because the heat resistance decreases. Furthermore, if the melting temperature exceeds 190°C, the uniform dispersion state in the thermoplastic resin composition A will deteriorate and the impact resistance will decrease when brominated polycarbonate is used, which is not preferable. The above-mentioned brominated polycarbonate needs to be used in combination with antimony trioxide used as a flame retardant additive, and the amount used is the same as that of the above-mentioned thermoplastic resin composition.
The amount is 3 to 25 parts by weight per 100 parts by weight of A. If the amount of brominated polycarbonate used is less than 3 parts by weight, the heat retardant effect will be small even when used in combination with antimony trioxide.
Further, if the amount exceeds 25 parts by weight, no improvement in the flame retardant effect can be obtained, and furthermore, the various properties of the resin composition are deteriorated, which is not preferable. Antimony trioxide C used in combination with brominated polycarbonate B is used as a flame retardant additive, and the amount used is determined by the weight ratio of brominated polycarbonate B and antimony trioxide C (B/
It is necessary to use C) at a ratio of 10/1 to 1/1. The flame-retardant thermoplastic resin composition of the present invention maintains a high degree of flame retardancy and a balance of various physical properties due to the synergistic effect of the combination of the above-mentioned brominated polycarbonate B and antimony trioxide C,
Such an effect is obtained by the above weight ratio, and it is not preferable to deviate from the above weight ratio range. In the present invention, the above-mentioned brominated polycarbonate B and antimony trioxide C can be freely increased or decreased within the scope of the present invention depending on the flame retardance required. On the other hand, if a halogen compound other than brominated polycarbonate B is used as a flame retardant, it will not only disrupt the excellent physical property balance of thermoplastic resin composition A, such as a decrease in heat resistance due to plasticization, but also cause molding using this composition. In this case, foaming and discoloration of the molded product may occur, which is undesirable. The embodiments of the method for producing the flame-retardant thermoplastic resin composition of the present invention are not particularly limited,
For example, a vinyl copolymer containing an acrylic rubber component, an aromatic vinyl copolymer, an aromatic polycarbonate resin, a brominated polycarbonate, and antimony trioxide are premixed in a mixer such as a V-type blender, It can be obtained by melt-kneading using a heated roll or a single-screw or multi-screw extruder. The flame-retardant thermoplastic resin composition of the present invention may contain various commonly used additives such as various stabilizers, dyes and pigments, and inorganic fillers, as required. The thermoplastic resin composition A of the present invention has excellent impact resistance, heat resistance, weather resistance, and easy moldability, and also has good compatibility with the flame retardant and flame retardant aid. Yes, almost no deterioration in the physical properties inherent to thermoplastic resin composition A was observed. Generally, aromatic polycarbonate resins and vinyl copolymers have poor compatibility and are prone to phase separation, which has the disadvantage that the excellent impact resistance inherent to polycarbonate resins is greatly reduced. On the other hand, rubber-containing resins tend to have poor moldability because of their relatively high melt viscosity, and in particular, their heat resistance is greatly reduced by molding. However, resin composition A, which is a mixture of three specific resin components of the present invention in a specific ratio, has good mutual compatibility among the resins, and has good weather resistance and impact resistance of acrylic rubber, and aromatic vinyl copolymer. This is an excellent resin composition that synergistically takes advantage of the good fluidity of the composite and the heat resistance and impact resistance of the aromatic polycarbonate resin. The flame-retardant thermoplastic resin composition of the present invention has excellent flame retardancy in addition to the excellent properties of resin composition A as described above. The present invention will be specifically explained below using Examples.

The reaction was completed by heat treatment at 90°C for 1 hour. The obtained powder was thoroughly washed with water and then dried at 80°C to obtain a polymer (2). (3) Preparation and evaluation of flame-retardant resin composition 20 parts of the above copolymer (), the above copolymer ()
15 parts, aromatic polycarbonate resin (Novarex 7022A, manufactured by Mitsubishi Chemical Corporation) 65 parts, melting temperature 160°C
A mixture of 15 parts of brominated polycarbonate and 5 parts of antimony trioxide was melt-kneaded in a 25 mm diameter vented extruder and pelletized to obtain the flame-retardant thermoplastic resin composition of the present invention. Next, the obtained pellets were used to make No. 1 dumbbells, 1/8 inch thick bending test pieces, and 1/4 inch thick heat deformation temperature measurement test pieces using a 5-ounce screw-type injection molding machine, and various physical properties were determined. The evaluation results are shown in Table 1. For comparison, the same proportions as above were used, except that tetrabromo bisphenol A (Comparative Example 1), decabromo biphenol ether (Comparative Example 2), and brominated phthalic anhydride (Comparative Example 3) were used as flame retardants. Table 1 also shows the results of evaluating various physical properties of the blended compositions molded in the same manner. As is clear from the results in Table 1, the molded products using tetrabromobisphenol A and brominated phthalic anhydride were significantly discolored and had poor surface appearance. In addition, those using decabrom biphenyl ether foam or have silver streaks, and the surface appearance is poor.
Furthermore, molded articles using flame retardants other than those specified in the present invention have a low heat distortion temperature. In contrast, those using brominated polycarbonate are found to be extremely superior in various physical properties.

A composition containing brominated polycarbonate having a melting temperature of 170° C. and antimony trioxide in the proportions shown in Table 2 was pelletized and test pieces were prepared in the same manner as in Example 1, and various physical properties were evaluated. The results are shown in Table 2. Table 2 also shows the results of evaluating various physical properties of the resin composition without adding brominated polycarbonate and antimony trioxide as Comparative Example 4. As is clear from the results in Table 2, the resin compositions of Examples 2 to 4 showed no decrease in strength and heat resistance compared to the resin composition of Comparative Example 4, which did not contain a flame retardant or flame retardant aid. It can be seen that no flame retardance was observed and that it exhibited excellent flame retardancy. Further, in Example 5, although a resin composition subjected to accelerated exposure was used, no change was observed in the surface appearance, and no substantial deterioration was observed in the physical properties. This also shows that the flame-retardant thermoplastic resin composition of the present invention has excellent weather resistance.
