Problems solved by technology

[0004] However, the fluorine atoms in the resin molecules reduce the surface free energy of the paint coating and make the paint itself highly hydrophobic, making it difficult for the paint to adhere to the surface of the substrate.
Under outdoor conditions, the coating is prone to peeling and bubbling between the coating coating and the substrate due to factors such as sunlight and high temperature, or the coating itself cracks to form micro-cracks. The durability of the coating needs to be further improved

Abstract

The invention discloses an anti-doodling transparent flame-retardant coating and belongs to the technical field of coatings. The paint comprises a component A and a component B, wherein the componentA comprises the following components in parts by weight: 20-30 parts of a soft monomer, 15-20 parts of a hard monomer, 15-20 parts of a fluorine-containing monomer, 20-25 parts of a transparent intumescent flame retardant, 10-15 parts of silica sol, 10-15 parts of oxa-cycloalkane, 5-10 parts of silicon heterocycloalkane, 5-8 parts of a surfactant and 80-100 parts of deionized water; the componentB is a curing agent; wherein the mass ratio of the component A to the component B is 100:(4-6). The flame-retardant coating has the advantages of high transparency, low VOC (volatile organic compound), water resistance, scrawling resistance and flame retardancy, and is suitable for outdoor wood cultural relic protection, public place wood decoration and other places with higher fireproof requirements. The invention further correspondingly discloses a preparation method of the anti-doodling transparent flame-retardant coating. The preparation method is simple in process steps, and the preparedcoating is suitable for outdoor wood cultural relic protection, public place wood decoration and other places with high fireproof requirements.

Description

technical field [0001] The invention relates to the technical field of paint and its preparation, more specifically, it relates to an anti-graffiti transparent flame-retardant paint and a preparation method thereof. Background technique [0002] Fluorine is the most electronegative element, and the F-C bond formed with carbon atoms has a bond energy as high as 485.3KJ / mol, so it is very stable. The fluorine atoms arranged in a helical shape in the fluorine-containing acrylic resin play a good role in "shielding protection" for the carbon skeleton, so that the inside of the injection material is protected from ultraviolet radiation and chemical reagents. Therefore, compared with ordinary acrylic resin, its performance is better. Based on the characteristics of fluorine-containing resin, it is widely used in various anti-graffiti coatings. [0003] For example, the Chinese patent with application publication number CN109401616A in the prior art discloses an anti-graffiti pai...
