Synthetic example 1

[0073] (Synthesis Example 1: Synthesis of Magnesium Potassium Titanate)

[0074] Mix 496.6g of titanium oxide, 213.7g of potassium carbonate, and 89.4g of magnesium hydroxide in the usual way, and fill the raw material mixture in a vibration mill (produced by Central Chemical Machinery Co., Ltd., MB-1), under the conditions of vibration number 1200cpm and amplitude 6.0mm Grind for 30 minutes. 48 mL of water was added to the ground mixture for mixing, and 15 g of the ground mixture was formed into a particle shape in a hydraulic press at a pressure of 10 MPa. The pellets were fired at 1000° C. for 4 hours in an electric furnace, cooled, and the obtained fired product was pulverized. The composition of the pulverized product is K 0.8 Mg 0.4 Ti 1.6 o 4 . Prepare 1L of 10% by weight aqueous slurry of the pulverized product, disperse it in a dispersion mill (manufactured by HOSOKAWA MICRON) for 15 minutes, suction filter the aqueous slurry, and dry the filtered cake (solid co...

Synthetic example 2

[0075] (Synthesis Example 2: Synthesis of Lithium Potassium Titanate)

[0076] Mix 542.0g of titanium oxide, 216.8g of potassium carbonate, and 41.2g of lithium carbonate in the usual way, and use the same method as Synthesis Example 1 to obtain an average long diameter of 15 μm and a composition of K 0.6 Li 0.27 Ti 1.73 o 3.9 lithium potassium titanate.

Synthetic example 3

[0077] (Synthesis Example 3: Synthesis of platy potassium octatitanate)

[0078] 154.6 g of lithium potassium titanate obtained in Synthesis Example 2 was dispersed in a solution obtained by dissolving 1.57 kg of 70% sulfuric acid in 29.4 L of water to form a 5% slurry. After stirring continuously with a stirring blade for about 5 hours, filter, wash with water, and dry to obtain platy titanic acid (H 2 Ti 2 o 5 ). The entire amount of platy titanic acid obtained was dispersed in a solution obtained by dissolving 0.74 kg of 85% potassium hydroxide in 11.2 L of water to form a 10% slurry. After stirring continuously with a stirring blade for about 5 hours, it was filtered, washed with water, and dried at 110° C. for 2 hours. Next, the dried product was fired in an electric furnace at 500° C. for 3 hours to obtain plate-shaped potassium octatitanate with an average major diameter of 16 μm.

Abstract

The invention provides granulated flaky titanic acid salts which little cause bridging or clogging in kneading and which bring about improvement in the manufacturing environment; a process for production of the salts; and resin compositions containing the salts. The granulated titanic acid salts can be produced by a process characterized by shaping a flaky titanic acid salt with a binder. The flaky titanic acid salt may be a layer titanic acid salt, flaky potassium octatitanate, a composite flaky metal titanate, or the like.

Description

technical field [0001] The present invention relates to a granular platy titanate, a method for producing the same, and a resin composition containing the granular platy titanate. Background technique [0002] In the past, when using fibrous chemical products such as whiskers, inorganic fibers, and organic fibers, there were problems such as deterioration of the working environment due to dust generation, poor transportability and workability due to low bulk specific gravity, and structure due to load during storage. Problems such as decreased uniform dispersion in the resin masterbatch caused by agglomeration. In particular, the decrease in uniform dispersibility in the resin masterbatch is an important problem because the performance of the resulting composite is remarkably deteriorated. [0003] In order to solve the above-mentioned problems, for example, it is disclosed that granulation is performed using a composition containing a surfactant and / or a binder as an activ...
