Problems solved by technology

Pigments are commonly used art supplies, and can be divided into traditional Chinese painting pigments, oil paints, and gouache pigments. Some organic pigments and synthetic pigments contain formaldehyde, which has certain toxicity and is not convenient for actual use. Complicated, resulting in low production efficiency of pigments, so it cannot meet the actual use needs
The disadvantages of common pigments currently on the market are that most of them use chemical raw materials, which are not healthy and environmentally friendly, and the colors are not natural enough, and the pigments do not have special smells such as fragrance.

Abstract

The invention relates to the technical field of pigment production processes, in particular to a red pigment for wall surface painting and a preparation method of the red pigment. The red pigment forwall surface painting comprises the following raw materials in parts by weight: 40-50 parts of an anemone red pigment extract, 55-65 parts of polyacrylic acid emulsion, 10-15 parts of arabian jasmineflower powder, 3-5 parts of oxidized hydroxypropyl starch, 30-40 parts of talcum powder, 1-3 parts of a water-based defoamer BEK-750, 3-5 parts of D-mannitol, 3-5 parts of sodium benzoate, 1-3 parts of fungicide, 2-4 parts of propylene glycol, 6-8 parts of sodium alginate and 55-60 parts of water. The prepared pigment is safe and environmentally friendly, is stable in quality, high in coloring power, bright in color and abundant and saturated in color, and the pigment has high color retention and flexibility; and the red pigment for wall surface painting has the characteristic of rapid drying,is bright in color, high in coloring power and long in storage time, cannot fade out due to solarization when used in an outdoor environment, is environmentally friendly and nontoxic when used in anindoor environment, is easy to store for a long time, and is quite suitable for wall surface painting of a school.

Description

technical field [0001] The invention relates to the technical field of pigment production technology, in particular to a red pigment for wall painting and a preparation method thereof. Background technique [0002] Pigment is a powdery substance used for coloring. It is insoluble in water, oil, resin or organic solvents, but can be uniformly dispersed in these media and can color the medium, and it has a certain covering power. [0003] Since ancient times, the source classification of pigments is mainly mineral source pigments, plant source pigments or animal source pigments and modern chemical synthetic pigments. Rich and colorful pigments have created a rich and colorful world of colors and art, and are the most precious cultural treasures so far. Pigment is a colored fine-grained powder substance. From the chemical composition, it can be divided into inorganic pigments and organic pigments. The inorganic pigments mainly include metal oxides, chromates, carbonates, sulfa...
