Abstract

The invention discloses micaceous iron antirust paint for medical use and a preparation method therefor. The micaceous iron antirust paint is prepared from micaceous iron oxide, phenolic resin coating, calcium carbonate, talcum powder, zinc phosphate, barium sulfate, tung oil, zinc oxide, stillingia oil and cobalt naphthenate. The micaceous iron antirust paint is applied to the rust protection and anticorrosion of medical instruments, the appearance of a coating film is reddish-orange, and the micaceous iron antirust paint has the solid content of 82-88 percent and the viscosity of 85-125s; the corrosion resistance is good, the impact strength is 55-75cm, and the resistance to salt water meets the condition that the micaceous iron antirust paint does not bubble and does not fall off in 15-35 days; the time for surface drying is 2-6 hours, and the time for solid drying is 20-22 hours; the preparation method is simple, the raw materials are simply and easily obtained, and the micaceous iron antirust paint can be extensively produced and continuously replace the existing materials.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical antirust paint for mica iron 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 combination 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 mica Iron oxide, zinc yellow antirust paint, etc. Used for rust prevention of bridges, ships, pipelines and other metals. Mica iron oxide antirust paint is a kind of paint mixed with mica iron oxide and drying oil. It has good permeability and wettability, soft paint fil...
