Embodiment Construction

[0019] The thermosetting nano coating of the embodiment of the present invention is composed of fluorine-containing acrylic / silicone resin with a weight ratio of 30 to 60%, pigment particles filled in the resin with a weight ratio of 4 to 30%, and the balance of solvent constitute. The structural formula (I) of this fluorine-containing acrylic / silicone resin is as follows:

[0020]

[0021] Among them, R, R 2 All are alkyl chains containing 1 to 4 carbon atoms, the value of x is 1 to 3, and the value of m is 83 to 277. Fluorine is contained in this structural formula. The fluorine-containing acrylic / silicone resin is provided by companies such as DuPont and Changxing.

[0022] The pigment particle is a nano powder obtained by grinding carbon black through a high-speed ball mill, and its particle diameter is less than or equal to 191.4 nanometers.

[0023] In order to obtain a better coating appearance, the solvents in the embodiments of the present invention are xylene ...

Abstract

The present invention provides one kind of thermosetting nanometer paint, which consists of fluoric acryl / silicone resin in 30-60 wt%, pigment particle filled inside the resin in 4-30 wt%, and solvent for the rest. The fluoric acryl / silicone resin has the structure as shown, and the pigment particle has size not greater than 191.4 nm. The thermosetting nanometer paint is prepared through mixing the said materials inside a reactor. When it is used, the thermosetting nanometer paint is first coated to the surface of workpiece and then heated to cure.

Description

【Technical field】 [0001] The present invention relates to a coating system, in particular to a thermosetting nano coating with antifouling, waterproof, good durability and high gloss, its preparation method and application method. 【Background technique】 [0002] With the improvement of living standards, people have higher and higher aesthetic requirements for the living environment and the appearance decoration of indoor furniture such as pianos. Higher requirements are put forward for coatings such as anti-fouling, waterproof, durability and high gloss. However, traditional coatings are increasingly unable to meet consumer demand. [0003] The coating of traditional paint generally includes a primer and a topcoat. The primer is the beginning of the entire coating and is directly attached to the surface of the substrate. It is usually used to provide color, seal the substrate, and enhance the adhesion between the topcoat and the substrate. The top coat is generally transpar...
