preparation example Construction

[0038] A preparation method for environment-friendly styrene-acrylic emulsion paint, comprising the following steps:

[0039] 1) Add the amount of styrene, methyl acrylate, epoxy resin and emulsifier into the container, and stir for 30-50min at a stirring speed of 600-1000r / min to obtain a mixed emulsion;

[0040] 2) Under the condition that the stirring speed is 350-700r / min, add the polyolefin elastomer, hydroxyethyl cellulose, sodium bicarbonate and antibacterial agent in the formula amount into the mixed emulsion, after adding, adjust the speed to 100-150r / min, and keep it for 10-30min to get semi-finished products;

[0041] 3) Add closed-cell perlite, talcum powder, leveling agent, drier, dispersant, defoamer, stabilizer and water into the semi-finished product, stir evenly, and obtain the environmentally friendly styrene-acrylic acid Emulsion paint.

Embodiment 1

[0043] An environment-friendly styrene-acrylic emulsion coating is prepared from the following components in parts by weight (see Table 1 for details). Its preparation process is as follows in order: 1) add the styrene, methyl acrylate, epoxy resin and emulsifier of formula quantity in the container, under the condition that stirring speed is 600r / min, stir 50min, obtain mixed emulsion; 2) in Under the condition that the stirring speed is 700r / min, the polyolefin elastomer, hydroxyethyl cellulose, sodium bicarbonate and antibacterial agent of the formula are added in the mixed emulsion. After the addition is completed, the speed is adjusted to 150r / min, and Keep it for 30 minutes to obtain a semi-finished product; 3) Add closed-cell perlite, talcum powder, leveling agent, drier, dispersant, defoamer, stabilizer and water into the semi-finished product, stir for 15 minutes, and obtain The environment-friendly styrene-acrylic emulsion paint.

Embodiment 2

[0045] An environment-friendly styrene-acrylic emulsion coating is prepared from the following components in parts by weight (see Table 1 for details).

Abstract

The invention discloses environment-friendly styrene-acrylic emulsion paint. The paint is prepared from the components in parts by weight as follows; 20-50 parts of styrene, 10-40 parts of methyl acrylate, 5-20 parts of epoxy resin, 5-10 parts of polyolefin elastomers, 10-15 parts of hydroxyethyl cellulose, 1-5 parts of sodium bicarbonate, 5-8 parts of closed cell perlite, 5-8 parts of talc powder, 1-8 parts of an antibacterial agent, 8-15 parts of an emulsifier and 15-25 parts of water. The paint adopts simple and reasonable composition, is non-toxic and odorless, has the clean and smooth surface and good water resistance, cannot fall off easily and is applicable to painting of internal walls, and a paint coat is dried quickly; besides, the paint is antibacterial, anti-mildew, washable, wear-resistant and long in service life; the paint cannot fall off easily, cannot pulverize and decolorize and is excellent in fouling resistance and weather resistance and convenient to use; meanwhile, a paint film is smooth and compact, and the thermal insulation effect is good. The invention further discloses a preparation method of the environment-friendly styrene-acrylic emulsion paint. The method is simple and safe in process and high in operability.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly styrene-acrylic emulsion coating and a preparation method thereof. Background technique [0002] Coating refers to a type of liquid or solid material that can form a thin film on the surface of an object under certain conditions for protection, decoration or other special functions (waterproof, insulation, rust prevention, mildew resistance, heat resistance, etc.). There are many types of coatings, which can include silicone coatings, silicate coatings, alkyd coatings, epoxy coatings, chlorinated rubber coatings, acrylic coatings, polyurethane coatings, and vinyl coatings according to film-forming substances. Various coatings are applied to different industries and occasions based on their own advantages. Among them, the coatings used for interior walls are called interior wall coatings. Appropriate interior wall coatings can protect the interior well, w...
