Abstract

The invention discloses external rust-proof paint of mechanical equipment. The external rust-proof paint of the mechanical equipment is prepared from the following raw materials in parts by weight: 20-30 parts of styrene-acrylic emulsion, 15-25 parts of acrylic emulsion, 8-14 parts of styrene, 3-7 parts of chlorinated paraffin, 6-11 parts of tributyl phosphate, 5-9 parts of dipentaerythritol, 3-6parts of compound filler, 2-4 parts of barium sulfate, 1-3 parts of a defoaming agent, 2-4 parts of a thickener, 2-5 parts of a curing agent, 2-3 parts of nano-zinc oxide and 20-30 parts of deionizedwater. According to the external rust-proof paint of the mechanical equipment, by controlling the types and proportion of the raw materials, the prepared rust-proof paint is low in cost, good in heatdissipation and excellent in heat resistance and salt resistant performance, and thus the service life of machinery can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to an antirust coating for external use of mechanical equipment and a preparation method thereof. Background technique [0002] The rust prevention of mechanical equipment has always been a problem that needs to be paid attention to in the process of industrial production and use. Mechanical equipment mostly uses steel as the material. The main matrix component of steel is iron. Iron is a very active element that is easily oxidized in humid air to form iron oxides. Once oxidized, it not only affects the appearance, but also may seriously affect the function of the product. The anti-corrosion ability of iron element in saline environment is also very unoptimistic. The main cause of corrosion is the pitting effect of chloride ions. In practice, the oxidation of iron and the corrosion of salt often work together, so that the corrosion resistance of steel is v...
