preparation example Construction

[0035] A preparation method of an organosilicon-modified silicate paint, comprising the following steps:

[0036] 1) Add the formulated amount of water into the container, then add the formulated amount of silicate, and stir for 5-15 minutes to obtain an aqueous silicate solution;

[0037] 2) Under the condition that the stirring speed is 250-600r / min, add the formula amount of methyl siloxane, silane coupling agent, polyolefin elastomer and emulsifier into the silicate aqueous solution, after the addition is completed, Adjust the speed to 100-120r / min, and keep it for 5-15min to get a semi-finished product;

[0038] 3) Add hydroxyethyl cellulose, talcum powder, antibacterial agent, leveling agent, drier, dispersant, defoamer and stabilizer into the semi-finished product and stir evenly to obtain the silicone Modified silicate coatings.

Embodiment 1

[0040] An organosilicon-modified silicate paint, comprising the following components in parts by weight (see Table 1 for details). The preparation process is as follows in sequence: 1) Add the formula amount of water into the container, then add the formula amount of silicate, and stir for 10 minutes to obtain the silicate aqueous solution; 2) Under the condition of stirring speed of 300r / min, the formula A certain amount of methyl siloxane, silane coupling agent, polyolefin elastomer and emulsifier are added in the silicate aqueous solution, after the addition is completed, the speed is adjusted to 110r / min, and kept for 10min to obtain a semi-finished product; 3) the Add hydroxyethyl cellulose, talcum powder, antibacterial agent, leveling agent, drier, dispersant, defoamer and stabilizer to the semi-finished product in the prescribed amount, and stir for 15 minutes to obtain the silicone-modified Silicate paint.

Embodiment 2

[0042] An organosilicon-modified silicate paint, comprising the following components in parts by weight (see Table 1 for details). The preparation process is as follows in sequence: 1) Add the formula amount of water into the container, then add the formula amount of silicate, and stir for 15 minutes to obtain the silicate aqueous solution; 2) Under the condition that the stirring speed is 600r / min, the formula A certain amount of methyl siloxane, silane coupling agent, polyolefin elastomer and emulsifier are added in the silicate aqueous solution. After the addition is completed, the speed is adjusted to 100r / min and kept for 5min to obtain a semi-finished product; 3) the Add hydroxyethyl cellulose, talcum powder, antibacterial agent, leveling agent, drier, dispersant, defoamer and stabilizer into the semi-finished product and stir for 25 minutes to obtain the silicone-modified Silicate paint.

Abstract

The invention discloses a silicone-modified silicate coating, comprising the following components in parts by weight: 20 to 50 parts of methylsiloxane, 10 to 30 parts of silicate, 5 to 20 parts of silane coupling agents, 5 to 10 parts of polyolefin elastomers, 10 to 15 parts of hydroxyethyl cellulose, 5 to 8 parts of talcum powder, 1 to 8 parts of antibacterial agents, 8 to 15 parts of emulsifiers and 15 to 25 parts of water. The coating disclosed by the invention is suitable for coating interior walls, is non-toxic, tasteless, safe and environment-friendly, can be penetrated into the wall a few millimeters, can form waterproof films on the wall surface and inside the wall, and is good in waterproof effect; additionally, the waterproof films cannot prevent the emission of moisture, and good ventilation effect can be achieved; a paint-coating film is smooth and compact, can be used for effectively preventing the adhesion and infiltration of dust, is washable and wear-resistant, and has long service life; and the silicone-modified silicate coating is not easy to fall off, is anti-powdering, non-discoloring and mildew-proof, and has excellent pollution resistance and good weather resistance. The invention also discloses a preparation method of the silicone-modified silicate coating, and the preparation method is simple and safe in process and strong in operability.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an organosilicon-modified silicate 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 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, while making the walls more beauti...
