Problems solved by technology

At present, the vast majority of enterprises are launching various effects through complex processes and color schemes, but limited by the lack of construction technology, it is often difficult to achieve uniform yin and yang effects on large-area walls, as well as the overall artistic beauty
Moreover, the stain resistance and scrub resistance of pearlescent effect art paints are poor, especially after being scratched by a watercolor pen, the scratches are difficult to remove, which affects the appearance

preparation example Construction

[0076] Preferably, the preparation method of described pearlescent pigment comprises the following steps:

[0077] The pearl powder is coated with a metal compound; the metal compound is selected from titanium tetrachloride or metal oxide.

[0078] Preferably, the metal compound is at least one selected from iron oxide, titanium dichloride and rutile titanium dioxide.

[0079] Preferably, the hydrophobic modification material is selected from titanium tetrachloride. The base material of the pearl powder is selected from natural mica, synthetic mica or glass.

[0080] Furthermore, if the pearl powder of different particle sizes is used to change the path of light in the paint film, we can see different and richer colors. Through the superposition of colors, it brings a three-dimensional effect to the vision. Visual effects.

[0081] Preferably, the particle size of the natural mica or synthetic mica is 5 μm-100 μm. Preferably, the pearlescent pigment is compounded from pear...

Abstract

The invention relates to a bio-based art paint and its preparation method and application. The bio-based art paint is prepared from raw materials comprising the following parts by weight: 20-50 parts of bio-based acrylic emulsion, 20-28 parts of pearlescent pigment, and 10-50 parts of water; The glass transition temperature of the acrylic polymer in the bio-based acrylic emulsion is -15°C-0°C. The coating has excellent freeze-thaw resistance and film-forming properties, extremely low VOC, and excellent stain resistance; at the same time, the construction is simple and can be diversified, and it is easy to achieve a strong three-dimensional effect. The surface of the paint film is rich in metallic texture and crystal flash effect. In addition, the use of bio-based raw materials at the same time reduces the dependence on petrochemical raw materials, is highly environmentally friendly, meets people's pursuit of environmental protection and artistic coatings, and has broad application prospects.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a bio-based art coating and its preparation method and application. Background technique [0002] While the coatings industry is booming, people's awareness of environmental protection and health is also increasing. However, the emulsion used in the current water-based coatings is synthesized from petroleum resources. With the depletion of petroleum resources, it is becoming more and more important to find other resources to replace petrochemical resources as raw materials for synthetic polymer materials. Replacing traditional petroleum products with safer plant renewable resources, such as sugar, natural oil, cornstarch and agricultural waste, not only reduces carbon dioxide emissions, alleviates the greenhouse effect, but also reduces dependence on petroleum, which is in line with people's environmental protection and The pursuit of sustainable development. [0003] Secondly, harmful ...
