Abstract

The invention discloses medical rust-removal and antirust paint and a preparation method therefor. The paint is prepared from the following raw materials: styrene, zinc phosphate, phosphoric acid, zinc oxide, zinc chrome yellow, organobentonite, a polyvinyl acetate emulsion, deionized water, ammonium persulfate and aluminum triphosphate. The paint which is applied to medical apparatuses is antirust, the viscosity of the paint is 60-80, the fineness of the paint is 40-60 [mu]m, the flexibility of the paint is 0.2-0.8mm and the adhesive force of the paint is level 1-2; the paint has good antiseptic property, impact resistance within 60-80cm, impact strength of 500-550N/cm, and salt water resistance of not blistering and not falling within 1-3 days; the surface-drying time is 0.1-0.5 hour, the hard-drying time is 8-12 hours and the covering power is 95-115g/cm<2>.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical rust-removing and anti-rust 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 rust removal, rust removal, graphite antirust paint, etc.; the latter relies on the chemical antirust effect of antirust pigments, such as benzene Vinyl, zinc yellow antirust paint, etc. Used for rust prevention of bridges, ships, pipelines and other metals. Styrene antirust paint is a paint mixed with styrene and drying oil. It has good permeability and wettability, soft paint film and strong adhesi...
