Embodiment 1

[0026] An anti-rust paint for ships, the components and the mass fraction of each component are as follows: 8 parts of styrene-acrylic emulsion, 16 parts of polyurethane emulsion, 2 parts of sodium gluconate, 0.8 parts of polyepoxysuccinic acid, 3 parts of ethoxyethanol, 0.5 part of polypropylene glycol and 20 parts of water.

[0027] The preparation method includes the following steps:

[0028] 1) Mix styrene-acrylic emulsion, polyurethane emulsion, sodium gluconate and film-forming aid, heat at 140 °C for 3 h, and cool to 80 °C to obtain a mixture;

[0029] 2) Mix the polyepoxysuccinic acid with water, heat for 3 hours, add it to the mixture obtained in step 1), maintain at 80 °C, stir for 3 hours to form a viscous ester, and finally add a defoamer, heat and stir evenly, and cool to Room temperature, ready to pack.

Embodiment 2

[0032] The preparation method includes the following steps:

[0033] 1) Mix styrene-acrylic emulsion, polyurethane emulsion, sodium gluconate and film-forming aid, heat at 140 °C for 3 h, and cool to 80 °C to obtain a mixture;

[0034] 2) Mix the polyepoxysuccinic acid with water, heat for 3 hours, add it to the mixture obtained in step 1), maintain at 80 °C, stir for 3 hours to form a viscous ester, and finally add a defoamer, heat and stir evenly, and cool to Room temperature, ready to pack.

Embodiment 3

[0036] An anti-rust paint for ships, the components and the mass fraction of each component are as follows: 10 parts of styrene-acrylic emulsion, 20 parts of polyurethane emulsion, 3 parts of sodium gluconate, 1.5 parts of polyepoxysuccinic acid, 6 parts of tert-butyl ether, 0.8 parts of propylene glycol, 8 parts of glutamic acid, 25 parts of water.

[0037] The preparation method includes the following steps:

[0038] 1) Mix styrene-acrylic emulsion, polyurethane emulsion, sodium gluconate, amino acid and film-forming aid, heat at 140 °C for 3 h, and cool to 80 °C to obtain a mixture;

[0039] 2) Mix the polyepoxysuccinic acid with water, heat for 3 hours, add it to the mixture obtained in step 1), maintain at 80 °C, stir for 3 hours to form a viscous ester, and finally add a defoamer, heat and stir evenly, and cool to Room temperature, ready to pack.

Abstract

The invention discloses an anti-rust paint for a ship and a preparation method thereof. The anti-rust paint comprises the following components in parts by weight: 8-12 parts of styrene-acrylate emulsions, 16-25 parts of polyurethane emulsions, 2-6 parts of sodium gluconate, 0.8-2.4 parts of polyepoxysuccinic acid, 3-8 parts of film-forming auxiliary agents, 0.5-1.8 parts of defoaming agents, 20-45 parts of water, 6-10 parts of amino acid and 2-5 parts of sodium citrate or disodium ethylene diamine tetraacetate. The anti-rust paint prepared through the interaction of all the components has the advantages of high water resistance, high rigidity, good paint film plumpness, sea water corrosion resistance, high biodegradability, use of safe and non-toxic components and wide application prospect and cannot cause serious pollution to a water body even if blended into sea water.

Description

technical field [0001] The invention belongs to the technical field of metal protective coatings, and in particular relates to a ship antirust paint and a preparation method thereof. Background technique [0002] In daily production and life, we use a lot of various metal and alloy products. Metal parts are often corroded during storage, transportation and use, causing great losses to people. Therefore, metal corrosion and anti-corrosion have also become a focus of attention. The loss caused by metal corrosion not only damages the shape, color and mechanical properties of the metal material itself, but also reduces the quality level, accuracy and sensitivity of its products. Losses due to metal corrosion are staggering. According to foreign statistics, about one third of the steel produced in the world is scrapped due to corrosion every year. [0003] To effectively inhibit metal corrosion, it is very important to prevent metal from directly contacting with oxygen and wat...
