preparation example Construction

[0027] The saturated fatty acid saponification solution may be a saponification solution of stearic acid, lauric acid and palmitic acid. The specific preparation method includes: saponifying saturated fatty acid and sodium hydroxide at a temperature of 70-90°C to obtain saponified liquid, wherein the amount of sodium hydroxide is 20-30% of the mass of saturated fatty acid.

[0028] Further, the mass ratio of the saturated fatty acid saponification liquid and alkylphenol polyoxyethylene ether sodium sulfate is 2-4:1; The mass ratio of betaine ester is 1-2:1; the mass ratio of the first treatment agent and the second treatment agent is 1-2:1. (The hydrophilic modification of graphene in the above-mentioned ratio range can well achieve the effect of modification and can well avoid excessive waste of material consumption.

Abstract

The invention belongs to the technical field of coatings, and particularly relates to an anti-fog coating and a preparation method thereof. The anti-fog coating comprises the following components in parts by weight: 60-80 parts of cured resin, 10-20 parts of a curing monomer, 0.01-0.05 part of modified graphene, 0.5-1.5 parts of a photoinitiator, 0.1-0.3 part of a leveling agent, and 10-23 parts of a solvent, wherein the modified graphene is graphene treated by a surface treating agent for enhancing mechanical properties. According to the anti-fog coating, modified graphene is introduced on the basis of multi-component copolymerization, and the surfaces of graphene particles are specially coated to prepare a functional coating, so that a good anti-fog self-cleaning function is achieved, and meanwhile, the hardness and the wear resistance of a coating are also remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-fog coating and a preparation method thereof. Background technique [0002] Anti-fog coating is a coating that adheres to the surface of the substrate and prevents fog from being produced. The reason for the fog is that hot air hits a cold object and condenses into small water droplets on its surface. The light produces diffuse reflection on the surface of these small water droplets, which gives people the feeling of fog. The formation of water droplets, anti-fog coatings have super-hydrophilic properties on the surface, which increases the surface tension of water. Water cannot form water droplets on its surface, but a layer of water film, which fundamentally prevents the formation of fog. . [0003] The perspective effect and mechanical properties of the existing anti-fog coatings are not ideal, the timeliness of the anti-fog effect is not long enough, th...
