Rebar water-based rust inhibitor

Abstract

The invention discloses a threaded steel aqueous anti-rusting agent and relates to the field of threaded steel corrosion resistance. The anti-rusting agent comprises the following components in partsby weight: 3-45 parts of a water resistant agent, 0.6-6.5 parts of an adhesive, 3-13 parts of an anti-rusting agent, 2-6 parts of a cosolvent and 30-90 parts of pure water. By adopting the anti-rusting agent, a uniform and dense protection layer with an anti-rusting function is rapidly formed on the surface of hot-roll threaded steel, so that damp and moisture can be prevented from direct contactwith the surface of the threaded steel, a function of retarding rusting of the threaded steel is achieved, and the problem that threaded steel is easily rusted and corroded in open air storage, marinetransportation, storage in weather environments with heavy rain and damp in south China is solved. Meanwhile water is adopted as a solvent, so that no irritative harmful smell is generated in the useprocess, the anti-rusting agent can be continuously circulated, and requirements of environment protection and sustainable production are met.

Description

Technical field: [0001] The invention relates to the field of anticorrosion of threaded steel, in particular to a water-based rust inhibitor for threaded steel. Background technique: [0002] Rebar is an economical and practical structural material widely used in concrete structures such as houses, bridges, highways, dams, and tunnels. With the continuous deepening of urbanization, the vigorous development of infrastructure construction and real estate has a strong demand for rebar, and users have put forward higher requirements for the corrosion resistance of rebar. The use and storage of rebar in the atmosphere will gradually produce chemical or electrochemical reactions with the surrounding medium, and it is easy to cause surface corrosion in humid, open air, sea transportation and other environments; at the same time, the corrosion of rebar leads to poor durability and affects the normal use of the structure. Serious harm has been brought about and the service life of t...

Problems solved by technology

Rust inhibitors in the prior art have the following disadvantages: 1, antirust oil, direct use of rebar coated with antirust oil will reduce its gripping force with concrete, and degreasing treatment is required before use, and this process needs to be increased Special equipment and degreasing products will increase the cost and bring inconvenience to users; 2. The first generation of water-based antirust agent is made of toxic and harmful substances such as nitrite and chromic anhydride, which is harmful to the human body and harmful to the human body. Serious environmental pollution; 3. The second generation of environmentally friendly water-based anti-rust agent is only limited to the anti-rust of rebar indoor storage, and fails to better solve the problem of easy corrosion during sea transportation, open-air storage, and heavy rain in the south; in order to solve Above-mentioned technical problem, propose a kind of new technical scheme
