Abstract

The invention provides a slow-release quenching agent for threaded steel to prevent and slow down the corrosion of threaded steel in the atmosphere. A slow-release quenching agent for threaded steel provided by the invention comprises the following components in parts by mass: 2-5 parts of sodium sulfate, 4-6 parts of sodium hydroxide, 1-2 parts of starch, and 5-7 parts of sodium bicarbonate 6-8 parts of sodium phenylacetate, 5-8 parts of alum, and 60-70 parts of water. The invention also provides a preparation method of the slow-release quenching agent for rebar. The slow-release quenching agent for rebars of the invention can effectively prevent and slow down the corrosion of rebars in the atmosphere.

Description

technical field [0001] The invention relates to a slow-release quenching agent for threaded steel. Background technique [0002] Rebar is a small section steel, generally widely used in civil engineering construction such as houses, bridges, roads, etc., mainly as the skeleton of reinforced concrete building components. The purpose of the rebar is to bear the tension in the concrete member. The thread surface with different concave and convex will be better combined with the concrete, which can prevent the structure from being separated due to insufficient friction between the steel bar and the concrete, resulting in structural damage. [0003] Rebar is easily corroded and rusted in surrounding media such as carbon dioxide, oxygen, water, and acid during storage, transportation, and use. Corrosion not only causes waste of steel and affects the appearance of rebar, but also reduces the strength of steel and the bonding force with concrete, causing safety hazards in productio...
