Anti-rust paint for treating surface of steamship and preparation method of anti-rust paint

Abstract

The invention relates to a method for preparing anti-rust paint for treating the surface of a steamship. The anti-rust paint is prepared from the following components: zinc powder, methyl ethyl ketone, alkyd resin, methacrylate, sodium tripolyphosphate, polymer polyol glycerin ether defoaming agent, hexanediol butyl ether acetate, triethylene diamine, glycerol, mixed tung oil, dimethylbenzene, dicumyl peroxide, silane coupling agent KH792, triallyl cyanurate, maleic anhydride, styrene, p-benzoquinone and p-tert-butylcatechol. The anti-rust paint for treating the surface of a steamship is wide in raw material sources and low in cost, the compatibility among the components can be improved due to addition of the film forming resin in the prescription, the film forming effect is greatly improved; the component prescription has strong adhesion, high hardness, scratch resistance, acid-alkali resistance, water resistance, oil resistance and excellent anti-rust performance to a metal surface, the painted film has high drying speed under a natural condition, and the service life of the painted film can be 8-10 years.

Description

technical field [0001] The invention relates to the technical field of rust prevention of metal products, in particular to a method for preparing an antirust paint for ship surface treatment. Background technique [0002] With the development of society, paint has been widely used in various fields. While paint plays an aesthetic role in treating the coating surface, it also plays an effective protective role in corrosion resistance and aging resistance. Since the ship has been driving in the river or the sea for many years, the external stimulation on the surface of the ship is relatively harsh. As a result, the anti-rust paint on the outer surface 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. Therefore, the develop...

Problems solved by technology

Since the ship has been driving in the river or the sea for many years, the external stimuli on the surface of the ship are relatively harsh, causing the anti-rust paint on the outer surface of the hull to fall off easily, requiring frequent repainting, 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.
