Problems solved by technology

[0002] Due to the harsh environment of ships traveling in rivers or seas for many years, 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
Existing anti-rust paints for ship bottom generally have poor weather resistance, easy to fall off, not wear-resistant, and not suitable for complex and harsh environmental problems

Abstract

The invention discloses antirust paint used for a boat bottom. The antirust paint is prepared from following raw materials in parts by weight: 12-15 of an amino resin, 2-3 of zinc powder, 1-2 of nano silicon carbide, 1-2 of phosphoric acid, 70-75 of an E-12 epoxy resin, 7-9 of aluminium triphosphate, 4-5 of butanol, 12-14 of an E-42 epoxy resin, 2-3 of tert-butyl hydroperoxide, 6-8 of zinc oxide, 6-9 of bistetradecanol ester, 15-19 of ethyl acetate, and 3-4 of a film-forming resin. The antirust paint comprises the film-forming resin in the formula, thus improving compatibility of each component and improving the film-forming effect. Paint film obtained by using the antirust paint has excellent adhesive force and impact resistance, and good wear resistance, oil resistance, solvent resistance, water proofness, brine resistance and adhesion force between layers.

Description

technical field [0001] The invention relates to a metal antirust paint, in particular to a marine metal antirust paint. 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 antirust paints for ship bottom generally have poor weather resistance, are easy to fall off, are not wear-resistant, and are not suitable for complex and harsh environmental problems. Contents of the invention [0003] The invention provides an antirust paint for ship bottom and a preparation method thereof, which has good mechanical stability, flexibility and surface hardness, good weather resistance and good wear resistance. [0004] Technical scheme of the present invention is: [0005] An antirust paint for ship bottom is characterize...
