のが望ましい。Function: By combining antimony trioxide and hydrated alumina in the form of fine particles, the present invention makes it possible to achieve both the excellent flame retardancy of antimony trioxide and the low smoke emission properties of hydrated alumina without impairing transparency. A finely powdered antimony trioxide-hydrated alumina composite composition can be obtained by low-temperature reaction in a liquid phase without requiring a large-scale reaction apparatus. The reaction temperature may be lower than the temperature at which antimony (Ill) alkoxide and aluminum (III) alkoxide decompose; however, for convenience of handling, O
~130°C is desirable. Hydrolysis of the reaction product from the above mixing and reaction can be carried out by directly adding decarboxylated distilled water to the reaction solution. The reaction temperature for this hydrolysis is suitably within the range of 0 to 130 DEG C. so that the alkoxide is not decomposed during the preparation of the alkoxide and is easy to handle. This hydrolysis produces a powdery precipitate. Separate this precipitate from the hydrolyzate using a centrifuge or the like, and if necessary, dry it by vacuum drying or the like.
Alternatively, a powdered antimony trioxide-hydrated alumina composite composition can be obtained by drying by spray drying while adjusting the slurry concentration of the precipitate-forming solution and, if necessary, performing re-drying. The antimony trioxide and hydrated alumina powder used in the present invention should be as fine as possible with a particle size of 3 μm or less, taking into account the miscibility and compatibility with the alkoxide solution and the flame retardancy and smoke generation properties of the resulting composite composition. Something is desirable.

(OEt) in various composition ratios and reacted with a toluene solvent while refluxing at 100-110°C. 9 To this reaction product, a decarboxylated ethanol aqueous solution was added in an amount 10 times the theoretical reaction amount to give a reaction product of 90-110°C. Hydrolysis at °C produced a powdery precipitate. This precipitate was separated and washed from the hydrolysis solution by centrifugation, and then dried at 70°C for a day and night to obtain a powder.

は。As shown in the measurement results in these two tables, when the powder of the present invention is used, compared to the case where conventional antimony trioxide is used, from an excess of antimony trioxide to about half the amount of hydrated alumina, the difficulty is the same. It has a flame retardant effect and also shows excellent transparency, and compared to the case of using conventional hydrated alumina, the flame retardant effect can be expected without much reduction in transparency. Table 2 (Note) (1) Oxygen index: Determined value according to JIS K 7201 (2) Transparency: Light transmittance value measured by a color meter of the composition sheet listed in the table Effect of the invention According to the present invention, high purity ultra Taking advantage of the characteristics of the alkoxide method that yields fine particles, each composition ratio can be adjusted to the desired composition by using either antimony (III) alkoxide or aluminum (III) alkoxide in its component powder, or by using both in their alkoxide form. A finely powdered antimony trioxide-hydrated alumina composite composition having the desired composition can be obtained by a reaction in which the antimony trioxide and hydrated alumina composite composition is arbitrarily mixed in a proportion corresponding to the desired composition and a hydrolysis reaction thereof. This composite composition powder.
