Abstract

The invention discloses a building steel bar antirust coating which is composed of following raw materials including, by mass, 55-70 parts of cement, 15-25 parts of chloroprene rubber latex, 3-7 parts of a latex regulating agent, 2-4 parts of a rust inhibitor, 0.3-1 part of a defoamer and 5-10 parts of water. Total amount of the components is 100 parts. The coating is a modified antirust coating that can prevent rust on steel bars in construction sites, remove iron rust and enhance gripping force between the steel bar and concrete. The invention also discloses a construction method of the coating.

Description

technical field [0001] The invention relates to an antirust coating for building steel bars and a construction method thereof, in particular to a modified antirust coating used for preventing corrosion of steel bars in construction engineering and a construction method thereof. Background technique [0002] In 2010, data released by the American Society of Corrosion Engineers (NACE) showed that the total annual corrosion loss in the United States had reached 300 billion US dollars, accounting for 4.2% of the gross national product (GDP). Another report pointed out that infrastructure-based Corrosion damage to steel bars has an annual economic loss of 150 billion US dollars, accounting for 50% of the total corrosion loss and 2% of GDP. In addition, the annual repair cost of infrastructure caused by corrosion of steel bars in the United Kingdom is 5.5 billion pounds, and the annual corrosion loss in Australia is 25 billion US dollars. In particular, it should be noted that cor...
