Abstract

The invention discloses a medical antirust paint and preparation method thereof. The medical antirust paint comprises the following raw materials: basic lead chromate silicate, epoxy resin, coal tar pitch, dibutyl phthalate, ethyl cellulose, castor oil, diphenylamine, benzotriazol, lanolin and xylene. The medical antirust paint has functions of rust and corrosion resistance for the medical utensils, film appearance is smooth and bright, viscosity is 80-100s, and covering power is 240-280g/cm<2>; the medical magnetic red lead antirust paint has high intensity and first grade clunging power, no abnormality is generated through salt spray resistance for 10-30 days, no bubble and shedding are generated through salt water resistance for 5-25 days; surface drying time is 2-6 hours, hard drying time is 15-35 hours, preparation method is simple, raw materials are simple and easily available, and the antirust paint can be widely produced and continuously substitutes the current materials.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical antirust paint and a preparation method thereof. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. Mainly divided into two categories of 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 prevention of bridges, ships, pipelines and other metals. [0003] The antirust paint used is roughly oily and water-based. Oil-based antirust paint makes it difficult to remove the greasy surface of the material, so it is rarel...
