Embodiment 1

[0023] Use ordinary paint to coat the surface of the container and mark it as group A, spray 10% dilute sulfuric acid with a pH of 5, place it for 48 hours under a light intensity of 1000 lux, count the surface conditions, and spray 10% NaOH with a pH of 9 , placed under the light intensity of 1000 lux for 48 hours, and the surface conditions were counted.

Embodiment 2

[0025] Select the coating prepared from the following ratio, and the coating is composed of the following weight ratio, 43 parts of unsaturated polyester resin, 25 parts of modified alkyd resin, 16 parts of palm kernel ester, 17 parts of silicone water repellent, 39 parts of calcium sulfate parts, 25 parts of titanium dioxide. The coating is applied on the surface of the container and marked as group B, spraying 10% concentration of dilute sulfuric acid with a pH of 5, and placing it for 48 hours under the light intensity of 1000 lux, counting the surface conditions, spraying 10% concentration of NaOH with a pH of 9, Under the light intensity of 1000 lux, it was placed for 48 hours, and the surface conditions were counted.

Embodiment 3

[0027] Select the coating prepared from the following ratio, and the coating is composed of the following weight ratio: 35 parts of unsaturated polyester resin, 20 parts of modified alkyd resin, 9 parts of palm kernel ester, 13 parts of silicone water repellent, 30 parts of calcium sulfate parts, 19 parts of titanium dioxide. The coating is applied on the surface of the container and marked as group C. Spray 10% dilute sulfuric acid with a pH of 5, place it for 48 hours under the light intensity of 1000 lux, and count the surface conditions. Spray 10% NaOH with a pH of 9. Under the light intensity of 1000 lux, it was placed for 48 hours, and the surface conditions were counted.

Abstract

The invention relates to the field of container protection, and discloses an anti-corrosion coating for a container. The anti-corrosion coating is technically characterized by being prepared from the following components in parts by weight: 35 to 50 parts of unsaturated polyester resin, 20 to 30 parts of modified alkyd resin, 9 to 21 parts of palm kernel ester, 13 to 21 parts of an organic silicon water repellent, 30 to 45 parts of titanium dioxide, 19 to 23 parts of calcium sulfate, 2 to 6 parts of epoxy resin, 5 to 10 parts of a fluorocarbon emulsion, 4 to 8 parts of sodium sulfonate condensation sodium salt, 0.2 to 0.8 part of hydroxypropyl methyl cellulose, 1 to 5 parts of tributyl phosphate, 1 to 2 parts of a defoaming agent and 2.4 to 3.2 parts of butyl cellosolve. The problem, in the existing common coating, that inner objects are wetted by seepage due to ocean transportation and long-time solarization treatment of the container is solved.

Description

technical field [0001] The invention relates to the field of container protection, in particular to a corrosion-resistant coating for containers. Background technique [0002] my country is the place where the container manufacturing industry gathers most. In 2007, when the manufacturing industry was in its heyday, the annual output of my country's containers reached 3.75 million TEUs, accounting for 96% of the total container production in the world. The position of "the world's largest container manufacturing country". [0003] The application of containers is very extensive, especially in international and military transportation are inseparable from transfer boxes and containers. The use of transshipment boxes and containers can ensure that the goods transported will not suffer losses. For example, when encountering wind, rain, snow, and hail, products that need to be kept secret need transfer boxes and containers. Although the existing containers have basically become...
