Embodiment 1

[0044] 34 parts by weight of thermosetting acrylic resin, 20 parts by weight of epoxy resin and 17 parts by weight of methylphenyl silicone resin were mixed at a rotation speed of 250 r / min to obtain a first mixture. Next, the above-mentioned first mixture was mixed with 7 parts by weight of auxiliary materials and 68 parts by weight of water at a rotation speed of 300 r / min to obtain a second mixture. The above second mixture was mixed with 12 parts by weight of lithopone at a rotation speed of 600 r / min to obtain a third mixture. Then the third mixture was mixed with 25 parts by weight of antibacterial agent to obtain the coating.

[0045] Among them, the auxiliary materials include butadienyl triethoxysilane, potassium lignosulfonate, cuprous oxide, water glass and EPDM rubber in a weight ratio of 4.3:3:0.05:1:0.5. The antibacterial agent includes dihydromyricetin, catechin and resveratrol in a weight ratio of 2:0.06:2.

Embodiment 2

[0047] 46 parts by weight of thermosetting acrylic resin, 27 parts by weight of epoxy resin and 26 parts by weight of methylphenyl silicone resin were mixed at a rotation speed of 280 r / min to obtain a first mixture. Next, the above-mentioned first mixture was mixed with 12 parts by weight of auxiliary materials and 88 parts by weight of water at a rotation speed of 500 r / min to obtain a second mixture. Among them, the auxiliary material contains gamma-glycidyl etheroxypropyl trimethoxysilane, potassium lignosulfonate, cuprous oxide, water glass and EPDM rubber with a weight ratio of 5:3.6:0.07:1.2:0.8.

[0048] The above second mixture was mixed with 18 parts by weight of lithopone at a rotation speed of 800 r / min to obtain a third mixture.

[0049] Dihydromyricetin, catechin and resveratrol in a weight ratio of 2:0.06:2 were mixed and ground to a particle size of 100 μm, then dissolved in an alcohol solution, and ultrasonically dispersed for 12 minutes to obtain a bacteriost...

Embodiment 3

[0052] 40 parts by weight of thermosetting acrylic resin, 23.5 parts by weight of epoxy resin and 21.5 parts by weight of methylphenyl silicone resin were mixed at a rotation speed of 265 r / min to obtain a first mixture. Next, the above-mentioned first mixture was mixed with 9.5 parts by weight of auxiliary materials and 78 parts by weight of water at a rotation speed of 400 r / min to obtain a second mixture. Among them, the auxiliary material contains a mixture of butadienyl triethoxysilane and γ-aminopropyl triethoxysilane with a weight ratio of 4.75:3.3:0.06:1.1:0.65, potassium lignosulfonate, cuprous oxide, Water glass and EPDM.

[0053] The above second mixture was mixed with 15 parts by weight of lithopone at a rotation speed of 700 r / min to obtain a third mixture.

[0054] Mix chitin and chitosan to obtain the first antibacterial substance. Dihydromyricetin, catechin and resveratrol in a weight ratio of 3:0.08:4 were mixed and ground to a particle size of 200 μm, then ...

Abstract

The invention relates to a coating for a bathroom and a preparation method thereof, and belongs to the field of a high polymer material. The coating comprises bacteriostatic agent, resin, lithopone, water and ingredients. The bacteriostatic agent comprises dihydromyricetin, catechinic acid and resveratrol. The resin comprises thermoset acrylic resin, epoxy resin, and methyl phenyl silicone resin. The ingredients comprise silane coupling agent, lignosulfonic acid, cuprous oxide, sodium silicate and ethylene-propylene-diene monomer. The coating has strong bacteriostatic action, and can effectively avoid germ and mould breeding for extreme humidity of the bathroom. The resin, the ingredients and water are mixed at the rotate speed of 300-500 r/min, and then mixed with lithopone at the rotate speed of 600-800 r/min, and mixed with the bacteriostatic agent, thus the coating is prepared. The preparation method is simple and the process is easy to control.

Description

technical field [0001] The invention relates to the field of macromolecular materials, and in particular to a coating for bathrooms and a preparation method thereof. Background technique [0002] Coating is a kind of solid film that can be coated on the surface of objects by different construction techniques to form a solid film with firm adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. Paint is a kind of paint, which refers to a class of liquid or solid materials that can form a thin film on the surface of an object under certain conditions to protect, decorate or have other special functions (insulation, rust prevention, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resins have mostly or completely replaced vegetable oils, so they are called paints. Coatings are not liquid, and powder coatings...
