Abstract

The invention discloses a top coating as well as a preparation method thereof. The top coating comprises a main agent and a hardener, wherein the main agent is refined by epoxy resin in combination with special pigments such as phthalocyanine blue, barium sulfate, talcum powder and xylene, and the hardener is a modified polyamide resin. The main agent is 24KG in mass, and the hardener is 3.4KG in mass. The top coating disclosed by the invention can be coated on various models of coatings or be coated by various models of coatings, and is used on ships, bridges and common steel concrete members. The top coating is flexible in film, strong in adhesion, and excellent in water-proof and seawater-proof performances. The thickness can reach 150 mu m by coating at one time. The top coating can be hardened at temperatures above -10 DEG C, and is easy to construct and good in weather resistance.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a finishing paint and a preparation method thereof. Background technique [0002] Since ships, bridges and general steel and concrete structures are exposed to air or water for a long time, they are easily damaged and affect their service life. With the continuous progress of society, people have studied coatings with various functions, such as water resistance and fire resistance. etc., painted on its surface to prolong its life. Due to limited technology, it is a difficult problem for human beings to study multi-functional coatings such as good water resistance, weather resistance, and strong adhesion. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a finishing paint and a preparation method thereof, aiming at improving the water resistance, weather resistance and adhesion of the finishing paint. ...
