Problems solved by technology

Due to the high brittleness of epoxy resin cured products, poor impact resistance, acid and alkali resistance, flexibility and temperature resistance, the application of epoxy resin coatings is limited. One of the key points of research, and in order to improve its mechanical properties, various inorganic fillers such as bentonite and graphene are often added therein, but these inorganic fillers have poor compatibility with epoxy resin, which easily causes poor storage stability of the coating. And it is easy to form agglomerates, which reduces the quality of the coating, and the adhesion level between the traditional water-based epoxy resin coating and the substrate is 2, although it can meet the requirements for the coating film in actual production and life, but for some coatings that need to be wiped frequently For substrates with poor surface smoothness, a stronger peel strength is still required to meet the durable protection of the substrate

Embodiment 1

[0028] The preparation method of modified nano titanium nitride comprises the following steps:

[0029] Dissolve sodium lauryl sulfate in hot water at 70°C for stirring and dispersing, then add nano-titanium nitride for stirring and dispersing, ultrasonically treat for 1.5 hours, and then filter and dry to obtain modified nano-titanium nitride. The mass ratio of sodium lauryl sulfate to nano-titanium nitride is 7:1.

[0030] The effect of modification is measured by sedimentation experiment. Weigh 1-1.5g of the above-mentioned modified nano-titanium nitride sample and place it in a graduated cylinder with a ground mouth. First add a small amount of xylene to fully wet the nano-titanium nitride-graphene oxide. Finally, add xylene until 20mL is fully vibrated evenly, let it stand for different times under room temperature, record the mass of the sediment, and convert it into a sedimentation index; the sedimentation index=(mass of the sedimented part of the sample / total sample ma...

Embodiment 2

[0037] The preparation method of modified nano titanium nitride comprises the following steps:

[0038] Dissolve sodium lauryl sulfate in hot water at 80°C for stirring and dispersing, then add nano-titanium nitride for stirring and dispersing, ultrasonically treat for 0.5h, and then filter and dry to obtain modified nano-titanium nitride. The mass ratio of sodium lauryl sulfate to nano-titanium nitride is 5:1.

[0039] It can be seen from the test that the unmodified nano-titanium nitride-graphene oxide will completely settle down in xylene for about 3-5 hours, while the modified nano-titanium nitride will only settle in 1.2-1.8 hours after 24 hours in xylene. % precipitation, only about 2.6-3.2% precipitation after 48h. Therefore, the modified nano-titanium nitride has better dispersion performance and better modification effect.

[0040] The preparation method of modified silicone resin comprises the following steps:

[0041] 1) Calculated in parts by weight, weigh 50 pa...

Embodiment 3

[0045] A nanocomposite anticorrosion coating, calculated in parts by weight, comprising the following components:

[0046]50 parts of aqueous epoxy emulsions, 24 parts of modified silicone resins of embodiment 1, 9 parts of modified nano-titanium nitrides of embodiment 1, 7 parts of bentonite, 12 parts of sodium hexametaphosphate, 4 parts of alcohol ester twelve, 0.3 parts of sodium oleate, 0.9 parts of hydrogenated castor oil, 0.3 parts of emulsified methyl silicone oil and 25 parts of water.

Abstract

The invention provides a nano composite anti-corrosive coating, which comprises the following components in parts by weight: 40-60 parts of aqueous epoxy emulsions, 20-30 parts of modified organic silicon resins, 6-12 parts of modified nano titanium nitride, 5-10 parts of bentonite, 10-16 parts of sodium hexametaphosphate, 2-6 parts of film-forming adhesives, 0.1-0.5 part of a dispersant, 0.6-1.2parts of hydrogenated castor oil, 0.1-0.5 part of a defoaming agent, and 20-30 parts of water. The modified silicone resin is mainly prepared from silicone resin, acrylic acid, an initiator and silicasol, and the modified nano titanium nitride is mainly prepared from nano titanium nitride and sodium dodecyl sulfate. The nano-composite anticorrosive coating not only has good anti-corrosive performance, but also has good high temperature resistance.
