preparation example Construction

[0069] Another aspect of the present invention is to provide a kind of preparation method of peacock blue waterborne acrylic metallic paint, preferably the method for preparing the peacock blue waterborne metallic paint composition described in the first aspect of the present invention, the method may further comprise the steps:

[0070] Step 1, mixing water-based acrylic resin, inorganic fillers, additives and water, and grinding;

[0071] In the present invention, in step 1, water-based acrylic resin, inorganic filler, additives and water are mixed and ground to obtain a mixture.

[0072] The present inventors found that the water-based acrylic resin can play a certain role of pre-dispersion. First, the water-based acrylic resin is mixed with inorganic fillers, additives and water, which can play a role of pre-dispersion, so that the inorganic particles can be better dispersed. Avoid agglomeration of particles and affect the gloss of the film after formation. After mixing e...

Embodiment 1

[0093] (1) Weigh 231.27g of water-based acrylic resin, 30.31g of light calcium carbonate (the content of calcium carbonate in the composition is 10%), 5.57g of deionized water, 0.39g of defoamer and appropriate amount of pearls are added to the experiment In the dispersing sand mill, start the experimental dispersing sand mill, grind the mixture, set the speed at 2200r / min for 1h, and add a small amount of deionized water during the grinding process;

[0094](2) After grinding, add 15.12g of peacock blue slurry to the experimental dispersion sand mill in step 1, set the rotating speed to 1000r / min, and continue grinding for 30min. During the grinding process, an appropriate amount of deionized water can be added, and the composition The total weight is 300g;

[0095] (3) The resulting product is left to stand, and impurities such as pearls are removed by gauze filtration to obtain the peacock blue water-based metallic paint composition 1.

Embodiment 2

[0097] (1) Weigh 226.69g of water-based acrylic resin, 45.12g of light calcium carbonate (the content of calcium carbonate in the composition is 15%), 6.69g of deionized water, 0.40g of defoamer and appropriate amount of pearls are added to the experiment In the dispersing sand mill, start the experimental dispersing sand mill, grind the mixture, set the speed at 2200r / min for 1h, and add a small amount of deionized water during the grinding process;

[0098] (2) After grinding, add 15.20 g of peacock blue pulp to the experimental dispersion sand mill in step 1, set the speed at 1000r / min, and continue grinding for 30 minutes. During the grinding process, an appropriate amount of deionized water can be added, and the composition The total weight is 300g;

[0099] (3) The resulting product was left to stand, and impurities such as pearls were removed by gauze filtration to obtain the peacock blue water-based metallic paint composition 2.

Abstract

The invention discloses a peacock blue water-based metallic paint composition and a preparation method thereof. The composition comprises the following raw materials in parts by weight: 100-180 partsof a water-based acrylic resin, 5-15 parts of peacock blue color paste, 10-80 parts of an inorganic filler, 0.05-1 part of a defoaming agent, and a proper amount of water, preferably 1-50 parts. The preparation method of the composition comprises the following steps: 1, mixing the water-based acrylic resin, the inorganic filler, the additive and the water, and grinding; and 2, adding peacock bluecolor paste, and grinding. According to the invention, the paint film formed by the composition is high in hardness, good in impact resistance, good in adhesive force, high in glossiness and the likeand has excellent comprehensive performance; and the method for preparing the composition is simple, easily available in raw materials, environmentally friendly and easy to implement, and is suitablefor large-scale industrial production.

Description

technical field [0001] The invention relates to the field of water-based paint, in particular to a peacock blue water-based metallic paint composition and a preparation method thereof. Background technique [0002] With the development of industrialization and urbanization, environmental safety has an increasingly important impact on people's health, so environmental safety has received more and more attention. Traditional solvent-based coatings contain a large amount of volatile organic compounds (VOC for short) in the process of manufacture and use. A large amount of toxic organic matter pollutes and destroys the environment and causes serious harm to the human body. [0003] Water-based paint is a type of paint that uses water as a solvent or dispersion medium, and has been widely used in the fields of construction, furniture, automobiles, and amusement. With the enhancement of people's awareness of environmental protection, in the fields of industrial coating, automotiv...
