Diamond glaze environment-friendly paint and preparation method thereof

Abstract

The invention discloses diamond glaze environment-friendly paint and a preparation method thereof, and relates to the technical field of paint. The water-based paint comprises 40%-50% of water-based acrylic resin, 3%-5% of nano silicon dioxide particles, 10%-15% of natural vegetable oil, 5%-8% of inorganic pigment, 20%-30% of water, 0.5% of a surfactant, 0.1% of a preservative, 0.2% of a pH regulator, 0.1% of a defoaming agent and 0.2% of a dispersing agent. The preparation method comprises the following steps: uniformly mixing water-based acrylic resin and water, sequentially adding main components such as nano silicon dioxide particles, natural vegetable oil and inorganic pigment, then adding auxiliary components such as a surfactant, a preservative, a pH regulator, a defoaming agent and a dispersing agent, uniformly stirring, and finally filtering to remove impurities to obtain a finished product. The water-based acrylic emulsion with high gloss and low VOC (volatile organic compounds) is used as a main base material, so that emission of harmful volatile organic compounds (VOCs) is greatly reduced; by adding the nano silicon dioxide particles, not only is the hardness of the paint film improved, but also the paint film is endowed with a diamond-like gloss effect, and the decorative property is improved.

Description

Technical Field

[0001] The invention belongs to the technical field of coatings, and in particular relates to a diamond glaze environmentally friendly paint and a preparation method thereof. Background Art

[0002] With the development of society and the improvement of people's environmental awareness, the requirements for coatings are also constantly increasing. Solvent-based coatings release a large amount of VOCs during production and use. These VOCs not only pollute the atmosphere, but also aggravate the greenhouse effect and the formation of photochemical smog. Long-term exposure to VOCs will have a negative impact on human health, including respiratory diseases, nervous system damage, etc. Solvent-based coatings have the risk of fire and explosion during storage and transportation. Traditional coatings often have difficulty in achieving high gloss and special decorative effects, which limits their application in the field of high-end decoration.

[0003] Although many environmentally friendly paints have appeared on the market, these paints often cannot achieve gloss and hardness comparable to traditional solvent-based paints. Some environmentally friendly paints perform poorly in terms of weather resistance and corrosion resistance and have a short service life. Existing environmentally friendly paints are prone to fading when exposed to the natural environment for a long time, affecting the appearance. Some environmentally friendly paints will have problems such as sagging and bubbling during the construction process, affecting the quality of the final paint film.

[0004] As people's awareness of environmental protection increases, the market demand for environmentally friendly coatings is growing. Consumers not only hope that the coatings have good environmental performance, but also hope that they have excellent decorative effects and excellent physical properties. Therefore, the present invention provides a diamond glaze environmentally friendly paint and a preparation method thereof, aiming to provide a new type of coating that is environmentally friendly, high gloss and has good decorative effects. Summary of the invention

[0005] To achieve the above object, the present invention is implemented by the following technical solutions: The present invention is a diamond glaze environmentally friendly paint and a preparation method thereof, comprising: Water-based acrylic resin 40%-50%, nano-silicon dioxide particles 3%-5%, natural vegetable oil 10%-15%, inorganic pigment 5%-8%, water 20%-30%, surfactant 0.5%, preservative 0.1%, pH adjuster 0.2%, defoamer 0.1%, dispersant 0.2%.

[0006] The present invention is further configured such that the water-based acrylic resin is a high-gloss, low-VOC water-based acrylic emulsion.

[0007] The present invention is further configured such that the particle size of the nano-silicon dioxide particles is less than 100 nanometers.

[0008] The present invention is further configured such that the natural vegetable oil is selected from one or more of soybean oil, linseed oil and palm oil.

[0009] The present invention is further configured such that the inorganic pigment is selected from one or more of red iron oxide, titanium dioxide, and carbon black.

[0010] The present invention is further configured such that the surfactant is a nonionic surfactant, preferably a polyoxyethylene alkyl ether.

[0011] The present invention is further configured such that the preservative is a quaternary ammonium salt preservative, preferably benzalkonium chloride.

[0012] The present invention is further configured such that the pH regulator is one of ammonia water or acetic acid.

[0013] The present invention is further configured such that the defoamer is a mineral oil type defoamer, preferably polydimethylsiloxane.

[0014] A method for preparing diamond glaze environmentally friendly paint comprises the following steps: (a) uniformly mixing water-based acrylic resin and water; (b), adding nano-silicon dioxide particles, natural vegetable oil, inorganic pigment and other main ingredients in sequence; (c) adding auxiliary ingredients such as surfactant, preservative, pH adjuster, defoamer and dispersant, and stirring evenly; (d) filtering to remove impurities and obtain the finished product.

[0015] The present invention has the following beneficial effects: 1. The present invention uses a high-gloss, low-VOC water-based acrylic emulsion as the main base material, which greatly reduces the emission of harmful volatile organic compounds (VOCs) and is environmentally friendly. The use of natural vegetable oils further enhances the ecological attributes of the product. The addition of nano-silicon dioxide particles not only improves the hardness of the paint film, but also gives the paint film a diamond-like gloss effect, thereby enhancing the decorativeness. The nano-silicon dioxide particles with a particle size of less than 100 nanometers ensure that the surface of the paint film is fine and smooth with high gloss. The use of natural vegetable oils such as soybean oil, linseed oil, and palm oil increases the flexibility of the paint film, making it less likely to crack and improving durability. This flexibility also means that the paint film can remain stable under different temperature changes and is suitable for a variety of climatic conditions. The use of inorganic pigments such as red iron oxide, titanium dioxide, and carbon black ensures the brightness and durability of the paint film color. The stability of the inorganic pigments also makes the paint film less likely to fade when exposed to sunlight for a long time.

[0016] 2. The present invention improves the rheology and leveling properties of the paint solution by using a surfactant, so that the coating is easy to apply during construction to form a uniform paint film. This leveling property helps to eliminate brush marks and bubbles that may appear during construction, making the paint film surface smoother and smoother; the addition of quaternary ammonium salt preservatives effectively inhibits the growth of microorganisms and extends the shelf life of the paint solution, which not only reduces the loss during storage, but also reduces the product quality problems caused by microbial contamination; the use of pH regulators such as ammonia water or acetic acid ensures that the paint solution is within a suitable pH range, helps to maintain the stability of the paint solution, and the control of the pH value is also conducive to improving the corrosion resistance and weather resistance of the paint film; the addition of mineral oil-based defoamers such as polydimethylsiloxane effectively reduces the formation of foam, avoids the appearance of bubbles in the paint film, and improves the quality of the paint film. The use of powders ensures the uniform dispersion of inorganic pigments in the paint solution, avoids pigment precipitation, and ensures the consistency of the paint film color.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
