Problems solved by technology

The traditional water-based anti-rust treatment is to dissolve sodium nitrite, dichromate, etc. in water at a certain concentration to form a water-based anti-rust liquid. It is characterized by simple operation and is suitable for short-term anti-rust between metal processing procedures. days or so, but this rust inhibitor is highly toxic to operators and has the disadvantage of seriously polluting the environment

Abstract

The invention discloses a water-base anti-rust agent composed of 30% to 75% film-forming agent, 0.5% to 6.0% inhibitor, 2% to 16% accessory ingredient and water. Bonding force of film layer to basal body is improved by adopting acrylic ester emulsion or water-base polyurethane emulsion as film-forming substance associated with components of inhibitor, accessory ingredient, etc. The water-base anti-rust agent is brushed on steel surface to form continuous compact protection layer, isolating steel surface from oxygen and water vapor effectively, for long lasting rust prevention. The anti-rust period of steel piece might be more than one year. The protecting film is quite compact, which maintains fundamental color of steel piece invariable. User can process next step of treatment directly without removing the protecting film, which reduces tiresome process of removing anti-rust coat. Operation modes include soaking, spraying, brush coating, etc. The invention is incombustible, nontoxic and environment-friendly. Contents of free formaldehyde, heavy metal and volatile organic meet qualified criteria. Bond strength of twice-brushed deformed steel bar to concrete is more than non-brushed test piece.

Description

technical field [0001] The invention relates to an antirust agent, in particular to a water-based antirust agent. Background technique [0002] Steel parts are prone to electrochemical corrosion and rust during the storage period from the production line to the user's use. In order to prevent steel parts from rusting during storage, anti-rust treatment must be carried out. Traditional anti-rust treatments include oil-based anti-rust treatment and water-based anti-rust treatment. Among them, the oily antirust treatment includes soft film antirust oil and hard film antirust oil. The soft film antirust oil is made of mineral oil (such as kerosene, diesel, engine oil or gear oil), oil-soluble corrosion inhibitor (such as petroleum sulfonic acid) Barium, zinc stearate) and other additives. It is characterized by simple operation and a certain anti-rust effect, but it is easy to pollute the operation site and transportation tools. For steel products that require subsequent treat...
