ればならない。また近年、我国においても。Since polypropylene has the drawbacks of being easily ignited and combustible, various flame retardant treatments are applied to it. In particular, polypropylene used in electrical products and building materials is increasingly required to have a higher degree of flame retardancy. For example, U.S.
The L standard requires high flame retardancy of V-1 to V-O for parts of home appliances such as TV frames. Therefore, products exported to the United States, such as home appliances, must be given a flame retardancy rating of V-1 to V-O. Also in our country in recent years.

テルが挙げられる。In general, organic flame retardants tend to cause large leaks during combustion,
Furthermore, although inorganic flame retardants are less likely to cause firedrops, they require a large amount of addition to make them flame retardant. In order to improve these drawbacks, various proposals have been made to combine organic flame retardants and inorganic flame retardants, but organic flame retardants that are effective in combination with inorganic flame retardants are particularly Bromdipheny A

せ選定する必要がある。Recently, there have been restrictions on the use of the polybrominated diphenyl ether mentioned above, mainly in Europe, so finding a suitable flame retardant formulation has become an urgent issue. However, it is generally difficult to obtain good flame retardancy without impairing other physical properties in polypropylene resin compositions that use a combination of organic flame retardants and inorganic flame retardants. It is necessary to select combinations according to the following.

徴とするボＩＪ ７’ロピレン樹脂組成物である。In view of the above-mentioned problems, the present inventors conducted extensive research and found that the combination of a specific organic flame retardant, Ni-F-L/Nbisbrominated phthalimide, and antimony trioxide is extremely effective in making polypropylene flame retardant. The present invention was completed based on the knowledge that the impact resistance of a polypropylene resin composition can be improved by using magnesium hydroxide, which is an inorganic flame retardant, in combination. That is, the present invention provides 15 to 10 parts of ethylene bisbrominated phthalimide represented by the following formula % to 100 parts by weight of polypropylene.
0 parts by weight, 3 to 50 parts by weight of antimony trioxide, and 30 to 150 parts by weight of magnesium hydroxide.

難燃性と耐衝撃性とに、優れた併用効果を示す。In the polypropylene resin composition of the invention, by using magnesium hydroxide together with ethylenebisbrominated phthalimide and antimony trioxide, flame retardance can be improved without impairing impact resistance. Generally, when only ethylene bisbrominated phthalimide and antimony trioxide are used in combination with polypropylene, the self-extinguishing and fire-preventing effects are low, and a large amount of addition is required, resulting in a decrease in impact resistance. Although it is possible to prevent the polypropylene resin composition from dripping by using a common inorganic substance such as talc, the self-extinguishing property is not improved and the impact resistance is further reduced. On the contrary,
In the polypropylene resin composition of the present invention, when magnesium hydroxide is used in combination with ethylenebisbrominated phthalimide and antimony trioxide, the amount of ethylenebisbrominated phthalimide added can be reduced, which is useful for improving impact resistance. . That is, in the present invention, the combined use of magnesium hydroxide is more effective than other inorganic substances such as talc.
Shows excellent combined effects on flame retardancy and impact resistance.

ある。Examples of ethylene bis-brominated phthalimide include known brominated flame retardants represented by the following (n: 1 to 4), such as ethylene bis-tetrabromphthalimide, ethylene bis-tribromophthalimide, and ethylene bis-dibromide. Examples include phthalimide, but ethylene bis-tetrabromo phthalimide, which has a high bromine content, is the most effective and preferred. Parts by weight, preferably 20 to 50 parts by weight.

い。Moreover, commercially available general antimony trioxide can be used. The amount of antimony trioxide to be blended is 6 to 50 parts by weight, preferably 5 to 30 parts by weight, based on 100 parts by weight of polypropylene. That is, if the amount of antimony trioxide in the polypropylene resin composition is less than the above lower limit, sufficient flame retardancy will not be obtained, and if it is more than the above upper limit, no improvement in flame retardance will be observed. Moreover, the specific gravity increases and the impact resistance decreases, which is undesirable.

The blending amount of such magnesium hydroxide is 30 parts by weight per 100 parts by weight of polyolefin.

This is not industrially suitable, since not only does it reduce the amount of heat, but also makes it difficult to mix wires and pelletize in an extruder when producing molded products.

おける耐衝撃性の向上に有効である。The polypropylene composition of the present invention is V-2, V-2 in UL94 standard (flammability test method standard for plastic materials).
It has a high degree of flame retardancy of 1.0 to V-Q and high impact resistance at the same time. The reason why such properties are obtained is not clear, but it is presumed that ethylenebisbrominated phthalimide and magnesium hydroxide act synergistically to exhibit high flame retardancy. In addition, ethylene bisbrominated phthalimide causes a decrease in impact resistance when added in large amounts, but due to the synergistic effect with magnesium hydroxide used in combination, the amount added can be reduced, which in turn improves impact resistance. I assume that it is helpful. Of course, unlike other general fillers, magnesium hydroxide is effective in improving the impact resistance of polypropylene resin compositions when added within a certain range.
