Abstract

The invention provides a metal antirust paint and a preparation method thereof. The metal antirust paint consists of the following ingredients in parts by mass: 35-45 parts of styrene-acrylic emulsion, 16-25 parts of iron oxide yellow, 8-16 parts of antirust yellow, 15-23 parts of zinc phosphate, 2-6 parts of zinc oxide, 2.5-5.5 parts of sodium dodecyl benzene sulfonate, 7-13 parts of mica powder, 2.3-5.5 parts of gallotannic acid, 2.2-5.8 parts of dihydric phosphate, 3-4.5 parts of polyacrylic copolymer emulsion, 1.3-3.7 parts of organic siloxane, 2.3-3.2 parts of sodium nitrite and 80-92 parts of deionized water. The metal antirust paint disclosed by the invention is harmless to the human body and the environment; a paint film is dried rapidly; furthermore, a metal is enabled to have passivation, rusting and rust prevention functions, and the metal can be directly painted without a rust prevention treatment, so the labor and time are saved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a metal antirust paint and a preparation method thereof. Background technique [0002] Metal is easily damaged by the action of the surrounding medium, that is, rust. When corroded, the mechanical properties such as strength, plasticity and toughness of the metal are destroyed, which greatly shortens the service life of the metal and causes a waste of resources. There are many types of metal antirust paints available on the market, but they generally contain organic solvents that are harmful to the human body and the environment, and the paint film dries slowly. Contents of the invention [0003] Technical problem to be solved: In view of the shortcomings of the existing metal antirust paint containing organic solvents harmful to the human body and the environment and slow drying speed of the paint film, the invention provides a metal antirust paint and a preparation method thereof. ...
