preparation example Construction

[0027] A preparation method for corrosion-resistant antirust paint, comprising the steps of:

[0028] Take the anti-rust active material and add the curing agent according to the mass ratio of 2~5:10~20, stir and mix at 50~60°C for 3~5h to obtain the mixed matrix, and take 200~300 parts of the mixed matrix, 30~50 parts of preservative additives, 5~10 parts of titanium dioxide, 2~7 parts of talc, 8~15 parts of lecithin, 8~13 parts of hydrogenated castor oil, 7~12 parts of glass flakes, 3~6 parts of γ -Aminopropyltriethoxysilane, 80~150 parts of water, stirred and mixed at 60~70°C for 40~50 minutes to obtain corrosion-resistant and anti-rust paint.

Embodiment 1

[0030] Anti-rust active substance: take dogwood seed shells and crush them through a 40-mesh sieve, collect the sieved particles, take the sieved particles and add distilled water at a mass ratio of 1:10, then add 40% of the mass fraction of distilled water to be 25% hydroxymethyl sulfonate Sodium acid solution, keep warm at 75°C for 4h, filter, take the filtrate to rotary evaporate, concentrate to 20 degrees Baume to get the concentrate, take the concentrate and mix it with polyvinyl butyral at a mass ratio of 3:6 to get the mixture, take Add acetone and ethyl acetate to the mixture at a mass ratio of 2:3:4, stir and mix for 20 minutes to obtain the antirust active substance.

[0031] Curing agent: (1) Take epoxy resin E-44 and add castor oil polyglycidyl ether in a mass ratio of 1:1 to mix, stir and mix at 55°C for 20 minutes to obtain a stirred mixture, take the stirred mixture and add di Ethanolamine was stirred and mixed for 1 hour to obtain mixture a;

Abstract

The invention discloses a corrosion-resistant and anti-rust paint and a preparation method thereof, belonging to the field of paints. In the present invention, the anti-rust active material is added into the curing agent according to the mass ratio of 2~5:10~20, stirred and mixed at 50~60°C to obtain the mixed matrix, calculated in parts by mass, taking 200~300 parts of the mixed matrix, 30 ~50 parts of preservative additives, 5~10 parts of titanium dioxide, 2~7 parts of talc, 8~15 parts of lecithin, 8~13 parts of hydrogenated castor oil, 7~12 parts of glass flakes, 3~6 parts of γ‑ Aminopropyltriethoxysilane, 80~150 parts of water, stirred and mixed at 60~70°C for 40~50min to obtain corrosion-resistant and antirust paint. The invention solves the problems of poor adhesion and poor corrosion resistance of existing antirust paints.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a corrosion-resistant and anti-rust paint and a preparation method thereof. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. Corrosion of metals is very common. The loss caused by metal corrosion not only damages the metal material itself in terms of its shape, color and mechanical properties, but more importantly, it reduces the quality level of the product, damages the accuracy and sensitivity, and affects or even loses its use value. The waste this creates is staggering. Therefore, it is increasingly important to develop excellent metal corrosion protection methods, and the most economical and effective method to prevent metal corrosion is the paint protection method. [0003] The protective effect of coatings on metal is very important. At present, the m...
