Problems solved by technology

In recent years, all countries have been continuously increasing investment in aviation and marine resources. Due to the extreme environment, the surface of the equipment used corrodes quickly, which not only affects the operation safety, but also brings a lot of damage to the repair and maintenance work. burden, while bringing high maintenance costs and reducing the service life of equipment
[0003] Most of the existing anti-corrosion coatings are composed of base oil, anti-rust agent, anti-oxidant and high molecular polymer resin. During use, it is easy to mix with carbon deposits and dust to form oil scale, thereby weakening the resistance to corrosion. In addition, under the influence of extreme temperature, light, humidity and other factors, the anti-corrosion coating is also prone to failure, thus losing the corrosion protection of the equipment

Embodiment 1

[0033] The high-performance anticorrosion coating of this embodiment is made of the following raw materials in parts by weight: 28 parts of modified nano-activated carbon, 21 parts of white oil, 18 parts of modified zeolite powder, 1.5 parts of hydrogenated castor oil, 8 parts of modified attapulgite, 6 parts of pumice sand, 3 parts of polyisobutylene, 5 parts of modified bentonite, 4 parts of polyvinyl alcohol, 3.5 parts of zinc chromate, and 1 part of pigment.

[0034] Among them, the modified attapulgite is made by the following steps: immerse the attapulgite in deionized water, add an appropriate amount of NaCl, mix it uniformly, perform ultrasonic treatment for 8 minutes, and the ultrasonic frequency is 50KHz, then filter and dry. That is, the weight ratio of the attapulgite, deionized water, and NaCl is 1:8:0.06.

[0035] Described modified nano activated carbon is made by following steps:

[0036] (1) After sieving the nano-activated carbon, wash it with water to remov...

Embodiment 2

[0050] This example is basically the same as Example 1, the difference is the weight ratio of raw material components, and its preparation method is the same as Example 1. Raw materials and their parts by weight are: 32 parts of modified nano-activated carbon, 18 parts of white oil, 21 parts of modified zeolite powder, 1 part of hydrogenated castor oil, 10 parts of modified attapulgite, 5 parts of pumice sand, and 4 parts of polyisobutylene , 4 parts of modified bentonite, 5 parts of polyvinyl alcohol, 3 parts of zinc chromate, 4 parts of pigment.

[0051] The anti-corrosion coating obtained in this example is tested for physical and chemical properties, the surface is flat and free of lumps; scratch resistance hardness 4H (GB / T6739-2006); adhesion level 2 (GB / T1720-1979); heat resistance test 800°C 120h: paint film Intact, no falling off (GB / T1735-2009); low temperature resistance test -70°C 120h: the paint film is complete, not falling off; alkali resistance test (120h): no ...

Embodiment 3
