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:

Embodiment 3

[0045] A heat-resistant and wear-resistant nano anti-corrosion coating, calculated in parts by weight, includes the following components:

[0046]50 parts of epoxy resin emulsion, 24 parts of modified silicone resin of embodiment 1, 9 parts of modified nano-titanium nitride of embodiment 1, 7 parts of bentonite, 12 parts of ceramic powder, 13 parts of graphite powder, alcohol ester twelve parts 4 parts, 0.3 parts of sodium oleate, 0.9 parts of pigment, 0.3 parts of emulsified methyl silicone oil and 25 parts of water.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a heat-resistant and wear-resistant nanometer anti-corrosion coating. Background technique [0002] With the development of machinery industry, the working environment of many equipments is becoming more and more diverse. Some equipment needs to work in a hot environment, some equipment needs to work under severe wear and tear, and some mechanical equipment needs to work under both conditions at the same time. If you work under these working conditions without taking anti-corrosion measures, the mechanical equipment will be corroded quickly, which will cause damage to the mechanical equipment, seriously cause production accidents, and cause personal harm. In order to improve the anti-corrosion ability of mechanical equipment, anti-corrosion technology has become one of the important research contents in the field of coating research at home and abroad.
