Metal antirust paint for ships and its preparation method

Abstract

The invention discloses a metal antirust paint for ships. The metal antirust paint is composed of the following raw materials by weight part: 5-8 of zinc powder, 5-8 of ferroferric oxide, 20-30 of methyl ethyl ketone, 30-40 of medium oil alkyd resin, 1-2 of HDl biuret, 5-10 of dicyclopentenyl ethoxyl methacrylate, 5-10 of hexanediol butyl ether acetate, 4-6 of magnesium hydroxide, 3-5 of nano-attapulgite clay, 1-2 of stannous pyrophosphate, 3-5 of sodium tripolyphosphate, and 1-2 of a polysiloxane defoaming agent, etc. The preparation method of the antirust paint involved in the invention is designed as a two-step process. In the first step, the zinc powder reacts with other ingredients to form a grid structure. The formed paint film has high hardness, scratch resistance and strong adhesion, and resists salt fog, saline, acid and base, water as well as oil. No damage can be caused to the paint film. The paint film also has super strong flexibility, and a general service life of 6-8 years.

Description

technical field [0001] The invention relates to a metal antirust paint, in particular to a marine metal antirust paint and a preparation method thereof. Background technique [0002] Ships have been driving in rivers or seas for many years, and the environment is harsh, so the anti-rust paint on the outside of the hull is easy to fall off, and it needs to be repainted frequently, which increases the cost and is not conducive to the protection of the hull. The existing marine metal antirust paint generally has poor weather resistance, is easy to fall off, and is not suitable for complex and harsh environments. Contents of the invention [0003] The invention provides a marine metal antirust paint and a preparation method thereof, which have good mechanical stability, flexibility and surface hardness, and good weather resistance. [0004] Technical scheme of the present invention is: [0005] A kind of antirust paint for marine metal is characterized in that it is made of ...
