Embodiment 1

[0030] (1) The fish scales in this example are a mixture of crucian carp, grass carp, and silver carp scales. In order to obtain a better metallic luster effect, fresh fish scales are preferred. Clean the fish scales, set the power of the ultrasonic cleaner to 280W, and the ultrasonic frequency to 100KHz, clean the fish scales in the ultrasonic cleaner for 30 minutes, remove the impurities on the surface of the fish scales, take them out, rinse them again with clean water, drain them, put them in a drying box, and dry them Carry out low-temperature pulverization, the refining temperature of low-temperature pulverization is -60°C, and the particle size of the pulverized fish scale powder is 20 microns, which is filtered through a sieve to obtain fish scale powder;

[0031] (2) Take 30 parts by mass of fish scale powder, 20 parts of mica powder with particle size of 150 microns, 20 parts of water-based fluorocarbon emulsion (solid content 50%), 20 parts of acrylic emulsion (solid...

Embodiment 2

[0035] (1) In this embodiment, the fish scales are carp scales. In order to obtain a better metallic luster effect, fresh fish scales are used. Clean the fish scales, set the power of the ultrasonic cleaner to 320W, and the ultrasonic frequency to 80KHz. Clean the fish scales in the ultrasonic cleaner for 30 minutes to remove impurities on the surface of the fish scales, remove them, rinse them again with clean water, drain them, put them in a drying box, and dry them. Carry out low-temperature pulverization, the refining temperature of low-temperature pulverization is -20°C, and the particle size of the pulverized fish scale powder is 20 microns, which is filtered through a sieve to obtain fish scale powder;

[0036] (2) Take 15 parts by mass of fish scale powder, 10 parts of mica powder with particle size of 50 microns, 20 parts of water-based fluorocarbon emulsion (solid content 50%), 30 parts of acrylic emulsion (solid content 50%), particle size of 50 - 10 parts of 180 mi...

Embodiment 3

[0040] (1) The fish scales in this example are mixed with crucian carp, grass carp, and goldfish scales. In order to obtain a better metallic luster effect, fresh fish scales are preferred. Clean the fish scales, set the power of the ultrasonic cleaner to 300W, and the ultrasonic frequency to 85KHz, clean the fish scales in the ultrasonic cleaner for 45 minutes, remove the impurities on the surface of the fish scales, take them out, rinse them again with clean water, drain them, put them in a drying box, and dry them Carry out low-temperature crushing, the refining temperature of low-temperature crushing is -40°C, and the particle size of the refined fish scale powder is 70 microns, which is filtered through a sieve to obtain fish scale powder;

[0041] (2) Take 18 parts by mass of fish scale powder, 18 parts of mica powder with particle size of 120 microns, 20 parts of water-based fluorocarbon emulsion (solid content 55%), 20 parts of acrylic emulsion (solid content 50%), part...

Abstract

The invention provides a biomass water-based decorative coating with metal texture and a preparation method. Fish scale is dried and refined at the low temperature, the obtained fish scale and mica powder are subjected to centralized dispersion and homogenization in airflow, a biomass pigment is obtained and uniformly mixed with a water-based fluorocarbon emulsion, an acrylic emulsion, glass micropowder and water, and the biomass water-based decorative coating with metal texture is obtained. The method overcomes the defects that existing coatings with metal texture are prone to oxidation due to use of metal powder and have weak metal gloss due to use of pigments, the coating contains fish scale powder assisted with the mica powder and thus has excellent gloss and metal texture, the coatingis easy to bond with bottom surfaces, has excellent scratch resistance, has attractiveness and protection functions and has the characteristics of fullness, smoothness, high hardness, extremely highadhesion, yellowing resistance, water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a biomass metallic texture water-based decorative coating and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, more and more attention is paid to environmental protection and health in the process of painting. Water-based paints use water as a solvent, resulting in a much lower content of volatile organic compounds (VOC; volatile organic compounds) than paints. The ecological environment will not cause damage, thereby driving the demand for water-based coatings. [0003] In order to obtain the effect of metallic texture coating, metal powder is generally added to metal texture paint to improve the effect of metallic luster. Common metal powders include aluminum powder, zinc powder, and lead powder. Metal powders in the form of alloys include copper-zinc powder (commonly known as gold powder), Zinc aluminum powder, st...
