Container internal-surface water-based anticorrosive paint and production method

Abstract

The invention discloses a container internal-surface water-based anticorrosive paint and a production method. The container internal-surface water-based anticorrosive paint comprises the following components in parts by weight: 50-60 parts of water-based acrylate epoxy modified resin, 5-10 parts of rutile type titanium dioxide pigment R237, 20-30 parts of antirust material aluminum tripolyphosphate, 2-5 parts of Ilspersant PE-100 nonionic surfactant, 0.5-1 part of Alex F-252 anticorrosive mildew-proof bactericide, 1-5 parts of nonionic surfactant Ilydropalat 3204 and 5-10 parts of Hydropalat 100 dispersing agent. The invention aims at providing a container internal-surface water-based anticorrosive paint and a production method, wherein grains, food, medicines, clothes and the like can be directly loaded and transported by containers, ships and vehicles without influencing human health, the waste of packaging materials is reduced, and the energy consumption in transportation processes is reduced.

Description

technical field [0001] The invention relates to a water-based anticorrosion coating for the inner surface of a container and a production method thereof. Background technique [0002] The anti-corrosion coating used on the inner surface of the existing container, because it contains more substances that are not conducive to human health, cannot directly contact with food, food, medicine, clothing, etc., resulting in the use of containers, ships, and vehicles to transport such products. It is very inconvenient, and the transportation efficiency is reduced. Due to the need for additional packaging, not only will packaging materials be wasted, but also the energy consumption during transportation will increase significantly. In addition, the existing water-based anti-corrosion coatings have a large gap compared with oil-based coatings in terms of water resistance and anti-corrosion properties. During use, problems such as cracking, falling off, mildew, short service life, and a...

Problems solved by technology

[0002] The anti-corrosion coating used on the inner surface of the existing container, because it contains more substances that are not conducive to human health, cannot directly contact with food, food, medicine, clothing, etc., resulting in the use of containers, ships, and vehicles to transport such products. It is very inconvenient, and the transportation efficiency is reduced. Due to the need for additional packaging, not only will the packaging materials be wasted, but also the energy consumption during transportation will increase significantly.

In addition, the existing water-based anti-corrosion coatings have a large gap compared with oil-based coatings in terms of water resistance and anti-corrosion properties. During use, problems such as cracking, falling off, mildew, short service life, and acid and alkali resistance often occur. Moreover, water-based coatings can only be applied above 0°C, and their low temperature resistance is poor, which makes it difficult to meet the requirements of many occasions.
