Steel structure surface rust removing agent

Abstract

The invention discloses a steel structure surface rust removing agent. The steel structure surface rust removing agent consists of the following raw materials in parts by weight: 45-50 parts of acrylic resin, 30-40 parts of organic silicon resin, 10-15 parts of fire retardant, 1-3 parts of corrosion inhibitor, 1-3 parts of penetrating agent, 4-8 parts of triethanolamine, 45-55 parts of de-ionized water, 4-6 parts of ethylene oxide, 3-6 parts of ammonium molybdate, 0.3-0.5 part of sodium ethylenediamine tetramethylene phosphonate, and 1-3 parts of fatty alcohol polyoxyethylene ether sodium sulfate, wherein the fire retardant is one or two of ammonium polyphosphate and pentaerythritol. The steel structure surface rust removing agent is different from a traditional acid rust removing agent, contains no strong acid and chloride ion component, and is free of corrosivity, low in cost, safe, environment-friendly and excellent in rust removing effect.

Description

technical field [0001] The invention belongs to the field of steel structure surface treatment, in particular to a steel structure surface rust remover. Background technique [0002] The anticorrosion quality of the steel structure is one of the main factors affecting the service life and structural safety of the steel structure. The traditional rust and oil removal methods for steel structures mainly include: 1. Shot blasting, which belongs to mechanical rust removal, has dead ends, incomplete rust removal, and dust pollution, without pre-corrosion protection. It is difficult to meet the standard requirements; 2. Manual grinding, thorough rust removal, no pre-corrosion, manual operation, serious dust pollution, and easy to bring harm to the health of operators; 3. Pickling rust removal, passivation or Phosphating pre-corrosion is a chemical rust removal, the process is complicated, consumes energy and water, and pollutes the environment. Therefore, there is an urgent need...
