Abstract

The invention relates to a preparation method of an anti-aging oil painting pigment, and belongs to the technical field of pigment preparation. Firstly bamboo split used as a raw material is treated by high temperature and high pressure steam and blasted to obtain pretreated fiber, the pretreated fiber is oxidized with a potassium permanganate solution to obtain reaction filter residue, iron phosphate ceramic powder is prepared from iron nitrate and a phosphoric acid solution as raw materials under the action of potassium thiocyanate and ethylenediaminetetraacetic acid, the iron phosphate ceramic powder used as an additive and the reaction filter residue are together used to modify an acrylic acid emulsion to obtain a pigment emulsion, and finally the pigment emulsion is mixed with other auxiliary materials to prepare the anti-aging oil painting pigment, and the anti-aging oil painting pigment obtained by the method has excellent aging resistance performance and has broad application prospects.

Description

technical field [0001] The invention relates to a preparation method of aging-resistant oil paint, which belongs to the technical field of pigment preparation. Background technique [0002] Oil paint originated and developed in Europe, and became an important painting material worldwide in modern times. Tempera, which was produced in European paintings before the 15th century, was the predecessor of oil paints. While using tempera painting, many painters continued to search for a more ideal blending agent, and oil paints came into being. Oil paints have been widely used in many forms since the early fifteenth century. Oil paint is also favored by the majority of painters for its excellent diversity. Through traditional painting techniques such as toning, glazing, impasto and light color, it can provide artists with excellent picture effects. [0003] Oil paint is a special painting paint for oil painting, which is made by mixing and grinding pigment powder with oil and g...
