METHOD FOR MANUFACTURING ECO-FRIENDLY PAINT CONTAINING INDIGO AND VOLCANIC SOIL

WIPO Patent Application WO/2020/111330

A1

The present invention provides a method for manufacturing an eco-friendly paint comprising the steps of: (a) mixing indigo (niram) and water to obtain a first mixture; (b) adding 2.5 to 5 parts by weight of a reducing agent to 30 to 50 parts by weight of the obtained first mixture to obtain a water-soluble second mixture; (c) sequentially adding 0.1 to 1 part by weight of a dispersant, 20 to 25 parts by weight of a white pigment, 2.5 to 5 parts by weight of a filler, 10 to 30 parts by weight of volcanic soil, 0.1 to 0.5 parts by weight of an antifoaming agent, and 0.1 to 1 parts by weight of a freezing stabilizer to the obtained second mixture to obtain a third mixture; and sequentially adding 10 to 20 parts by weight of a water-soluble acrylic resin and 0.5 to 2 parts by weight of a thickener to the obtained third mixture to obtain a fourth mixture. The method for manufacturing an eco-friendly paint of the present invention and an eco-friendly paint composition manufactured thereby can be effectively used as eco-friendly materials in building materials and the field of interior design .
