Problems solved by technology

[0003] There are also many types of anti-fouling and anti-sticking coatings, but most of them are solvent-based. Because of their high organic solvent content, they are not suitable for indoor use.
As described in patent CN101275056A, anti-sticking and anti-graffiti coatings are mainly composed of 20-70% fluoropolymer resin, 1-7% fluorine-containing surfactant, 1-5% nano powder, 0.1-2% metal drier, and 20% solvent. ~80%, of which a large amount of solvent volatilizes, causing huge pollution to the environment

Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with specific embodiments. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0055] It should be noted that the specific manufacturers of the raw materials used in the following examples are respectively:

[0056] 1. The polymer emulsion can be fluorine-silicon modified acrylate emulsion from Weihai Xinyuan Chemical Company, with a solid content of about 45% and a glass transition temperature of 25°C.

[0057] 2. The hydrophobic agent is wax emulsion of model HF200 produced by Shenzhen Haichuan Chemical Technology Co., Ltd.

[0058] 3. The first anti-adhesive agent uses the fluorine additive of the model FS-81 produced by DuPont Company.

[0059] 4. The second anti-adhesive additive is a polyether-modified hydroxyl-functional polydimethylsiloxane solution produced by BYK Company, with a hydroxyl...

Abstract

The invention discloses an antifouling adhesive preventing coating which comprises the following components in parts by weight: 60-80 parts of polymer emulsion, 3-7 parts of water repellent agent, 1-2 parts of first adhesive preventing agent and 3-7 parts of second adhesive preventing agent, wherein the polymer emulsion is selected from one of fluorine and silicon modified acrylate emulsion, fluorine emulsion and silicon acrylic emulsion; the water repellent agent is water-soluble wax emulsion; the first adhesive preventing agent is a fluorine modified surface auxiliary agent with a water and oil repellent structure; and the second adhesive preventing agent is polyether modified hydroxyl functional polydimethylsiloxane. The invention also discloses a preparation method of the antifouling adhesive preventing coating. The coating of the invention has the performances of low surface energy, water and oil repellency, oil fouling resistance, adhesive sticker bonding prevention, and the like and has favorable antifouling adhesive preventing function and superhigh scrubbing resistance and is rapid and convenient for construction. Compared with the market sold solvent type product, the invention has the characteristic of environmental protection and can be suitable for indoor coating.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to antifouling and antisticking coatings, 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, such as insulation, rust prevention, mildew resistance, heat resistance, 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. Due to the many functions of coatings, there are many types of coatings currently available on the market, and anti-fouling and anti-sticking coatings are one of them. [0003] There are also many types of anti-fouling and anti-sticking coatings, but most of them are solvent-based. Because of their high organic so...
