[0002] Anticorrosive coatings are generally divided into conventional anticorrosive coatings and heavy-duty anticorrosive coatings, and are an indispensable type of coating in paint coatings. Conventional anticorrosive coatings are used to prevent corrosion of metals and other materials under normal conditions, protecting the service life of non-ferrous metals; heavy-duty anticorrosive coatings are a type of anticorrosive coating that can be used in relatively harsh corrosive environments and has a longer protection period than conventional anticorrosive coatings. When used, they are often used together with a paint brush.

[0003] In the existing paint brushes for anti-corrosion paint, during use, the paint brush needs to be frequently dipped into a paint bucket, and a large amount of paint often drips when the paint brush is taken out, causing waste. In the process of painting, paint also drips from the brush roll onto the ground, causing ground pollution. Frequent immersion in the paint bucket also leads to low painting efficiency and a short service life of the paint brush. Utility Model Content
