Abstract

The invention discloses a rust inhibitor for a steel bar for an autoclaved sand aerated concrete board and a preparation method. The rust inhibitor is prepared from the following components in percentage by weight: 53 to 57 percent of carboxylic butadiene-styrene latex, 1.2 to 1.7 percent of iron oxide red, 8 to 11 percent of slaked lime, 3.2 to 3.7 percent of high-efficiency thickener, 18 to 22 percent of quartz sand, 5 to 10 percent of sand aerated concrete board waste material and 3 to 7 percent of tap water. Raw materials of the rust inhibitor provided by the invention are easily purchased, and the rust inhibitor has a low cost and a simple confecting process, can be abundantly confected once to be stored and used, has high adhesive force with the steel bar and is environmentally friendly and pollution-free.

Description

technical field [0001] The invention relates to an antirust agent, in particular to an antirust agent used for steel bars of autoclaved sand aerated concrete plates and a preparation method thereof. Background technique [0002] Lightweight autoclaved sand aerated concrete slab is a green and environmentally friendly new building material made of steel mesh cage as the skeleton and lime, cement, sand, aluminum powder and other materials through batching, pouring, static stopping, cutting, and autoclaving. A green building material vigorously developed by the country. The lightweight autoclaved sand aerated concrete product is a porous material. Oxygen, carbon dioxide, and moisture in the air can easily enter the plate and contact the steel mesh cage, which will cause corrosion of the steel bar and affect the stress of the plate and the entire structure. [0003] Antirust agent for steel bars is a necessary material for the coating of steel mesh cages in the production of li...
