preparation example Construction

[0033]The present invention also relates to a preparation method of the above-mentioned organic-inorganic composite water-based aluminum powder paint, the steps of the preparation method are as follows:

[0034] Add defoamer and film-forming aids to styrene-acrylic emulsion or pure acrylic emulsion to disperse evenly, add fillers and aluminum powder to water to form a slurry, add additives to styrene-acrylic emulsion or pure acrylic emulsion After the wet slurry is evenly dispersed, add a thickener. After testing to reach the specified viscosity, add inorganic silicate solution under stirring. After adding, disperse evenly. After passing the test, filter, measure and pack.

[0035] The styrene-acrylic emulsion or pure acrylic emulsion can be matched with inorganic silicate.

[0036] The styrene-acrylic emulsion or pure acrylic emulsion and inorganic silicate matching test is as follows: Weigh 2 parts of styrene-acrylic emulsion or pure acrylic emulsion, slowly add 1 part of si...

Embodiment 1

[0038] Example 1: 40 parts of TB02 styrene-acrylic emulsion, 0.4 parts of silicone defoamer, 1.5 parts of alcohol ester twelve film-forming aids, 16.6 parts of water, 15 parts of calcium carbonate, 6 parts of aluminum powder, and 0.5 parts of polyurethane thickener , 20 parts of silicate solution.

[0039] Process: Weigh the formulated amount of emulsion, slowly add the formulated amount of defoamer and film-forming aid at 1000r / min and mix evenly; weigh the formulated amount of water, add the formulated amount of filler and aluminum powder and mix to form a slurry; Weigh the amount of silicate solution for later use; reduce the stirring speed of the emulsion to 800r / min, slowly add the slurry, disperse for 30 minutes, add a thickener to adjust the viscosity to 70KU, slowly add silicate, continue to stir and disperse after adding 20 minutes, sampling and testing, filtering, measuring and packaging after passing the test.

Embodiment 2

[0040] Example 2: 42 parts of BLJ6511 pure acrylic emulsion, 0.5 part of silicone defoamer, 1.0 part of alcohol ester dodeca membrane aid, 20 parts of water, 13 parts of quartz powder, 5 parts of aluminum powder, 0.5 part of polyurethane thickener, 18 parts of silicate solution.

Abstract

The invention provides an organic-inorganic composite water-based aluminum powder paint and a preparation method thereof. The raw materials and contents of the water-based aluminum powder paint are: 30-45 parts of styrene-acrylic emulsion or pure acrylic emulsion, 0.3-0.8 parts of defoaming agent, film-forming 0.5-2.0 parts of agent, 15-20 parts of water, 5-15 parts of filler, 5-8 parts of water-based aluminum powder, 0.3-1 part of thickener, 15-25 parts of inorganic silicate; the preparation method is: Add defoamer and film-forming aids to the emulsion to disperse evenly; add fillers and aluminum powder to water to form a slurry, add the wetted slurry to the emulsion with additives, add a thickener after the dispersion is uniform, and detect When it reaches the specified viscosity, add silicate under stirring to disperse evenly, measure and pack after passing the test. The product of the invention has high hardness, temperature resistance, solvent resistance, durability, good adhesion, flexibility and other mechanical properties, and also realizes odorless, low VOC, safety and environmental protection.

Description

【Technical field】 [0001] The invention relates to an organic-inorganic composite water-based aluminum powder paint and a preparation method thereof. 【Background technique】 [0002] Porcelain - There is evidence that it was first created by the Huaxia nation in the late Eastern Han Dynasty (1800 years ago), and it was invented by the Chinese. The ceramic techniques were continuously iterated and passed down to the Yuan Dynasty. The ingenuity was unique, and the rare Yuan blue and white flowers were finally born. Yuan blue and white are directly painted on the green body with cobalt blue pigment, then applied transparent glaze, and fired at high temperature once, with high efficiency and high yield and energy saving. The transition from pottery to porcelain is due to the glaze silicate (calcium aluminum silicate) pioneered by the Chinese. After the Yuan blue and white glaze is sintered at about 1300°C, a layer of high-transparency and high-gloss glaze is formed, which is cal...
