Hydrotalcite particles and manufacturing method thereof, and resin stabilizer and resin composition thereof

The present invention provides a manufacturing method for producing hydrotalcite particles, and the method comprises the steps of: a first step of preparing an aluminate solution by dissolving aluminum hydroxide in an alkali solution; a second step of reacting the aluminate solution obtained in the first step with carbon dioxide to precipitate a low crystallinity aluminum compound; a third step of preparing a reactant containing hydrotalcite core particles by mixing a low crystallinity aluminum compound obtained in the second step with a magnesium compound; and a fourth step of synthesizing the hydrotalcite particles by hydrothermally reacting the reactant obtained in the third step. According to this manufacturing method, excellent thermal resistance, transparency, fluidity, and the like can be imparted to the hydrotalcite particles, and hydrotalcite particles which can be used as a resin stabilizer or the like can be obtained.
