Abstract

The invention discloses a medical quick-drying water-based antirust paint and a preparation method thereof. The paint is prepared from an acrylic acid emulsion, a shellac copolymer emulsion, zinc oxide, ethanol, phenol, sodium metaborate, light calcium carbonate, barium sulfate, iron oxide red and talcum powder. When being used for resisting rust and corrosion for medical devices, the paint has the deoxidization effect. The coated film appears iron red and is smooth, the viscosity is 60-80s, and the hardness is 3-5. The adhesive force is first-grade; the paint has high water resistance, and does not have abnormity after being immersed in water; the impact strength is 500-700 N/cm; the paint has high salt tolerance, and can not discolor or blister after being immersed in a 3% sodium chloride water solution at 25 DEG C for 10-30 days; the surface drying time is 10-30 minutes; and the solid drying time is 2-6 hours. The paint has the advantages of simple preparation method and simple and accessible raw materials, and can be widely produced and continuously substituted for the existing materials.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical quick-drying water-based antirust coating and a preparation method thereof. Background technique [0002] Coatings that protect metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea acrylic emulsions, 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 pigments and paints 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 the chemical antirust effect of antirust pigments, such as red Dan, zinc yellow antirust paint, etc. Used for rust ...
