Abstract

The invention discloses a rustproof anti-crush coating for steel and iron and a preparation method of the rustproof anti-crush coating. The preparation method comprises the following steps: weighing spindle oil, mercury sulfate, benzotriazole, paraffin, diphenylamine, ethyecellulose, vaseline, polybutadiene polyalcohol, petroleum sodium sulfonate ketone, polyether polyisocyanate and dimethylbenzene, stirring the raw materials and then grinding the stirred raw materials, wherein the coating is used for steel and iron surface protection, the coating is smooth in appearance, the viscosity is 60-100 s, surface drying time is 1-5 h, and hard drying time is 20-24 h; the covering force is 200-240 g/cm<3>, and the coating has high adhesive force for metals and is hard in coating film; the coating is high in dampproof and rustproof capacities and water resistance, the shock resistance is 70-90 cm, the salt water resistance is 14-18 d under the condition of soaking in water of 30 DEG C, and the coating is free of bubbling or dropping; the flexibility is 2-4 mm, and the crushing and dropping resistance is high.

Description

technical field [0001] The invention relates to a coating for iron and steel surfaces, in particular to an antirust and anti-shatter coating for iron and steel and a preparation method thereof. Background technique [0002] Antirust coatings are coatings that protect metal surfaces from chemical or electrochemical corrosion of the atmosphere, sea water, etc. Coating anti-rust coatings on the metal surface can effectively prevent the direct invasion of various corrosive substances in the atmosphere, so as to maximize the extension of the service life of the metal. It can be divided into two categories: physical and chemical antirust paint. The former relies on the proper coordination of benzotriazole and paint to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on antirust benzotriazole Chemical antirust effect, such as spindle oil, zinc yellow antirust paint, etc. ...
