Abstract

The invention discloses a crack-resistant and durable coating, which is prepared from the following raw materials in parts by weight: 2.3-3.8 parts of alkaline earth metal aluminate, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide 1.5-2.6 parts, 2.6-4.7 parts of dihydroxy polymethyl vinyl siloxane, 1.3-1.8 parts of glyoxal, 4-10 parts of demineralized water, 3-5.8 parts of carboxylated nitrile rubber, cumene hydroperoxide 2.5-3.2 parts and hydrogenated castor oil 1.3-3.8 parts. Compared with the existing waterproof paint, the present invention has the following advantages: hard paint film, good wear resistance, strong adhesion, and good water resistance, especially suitable for coating inner walls, outer walls and roofs; Carboxylated nitrile rubber is added to the ingredients, which has good adhesion, crack resistance and durability.

Description

technical field [0001] The invention relates to a crack-resistant and durable coating, which belongs to the field of building materials. Background technique [0002] The so-called 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 (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. According to the function, it can be divided into decorative coatings, anti-corrosion coatings, conductive coatings, anti-rust coatings, high-temperature-resistant coatings, temperature-indicating coatings, heat-insulating coatings, fire-resistant coatings, waterproof coatings, etc. There are many types of waterproof coatings, but most of t...
