Abstract

The invention relates to the technical field of antifouling coating materials for marine ships, and discloses an antifouling coating material for ship surfaces. The coating material comprises the following raw materials in parts by weight: 45-60 parts of organic silicon modified epoxy resin, 5-20 parts of polytetrafluoroethylene, 5-15 parts of paraffin oil, 5-10 parts of ethanol, 3-6 parts of nanotitanium dioxide, 2-5 parts of magnesium oxide, 0.5-0.8 parts of talcum powder, 0.5-2 parts of dodecyl alcohol, 3-8 parts of chitin / chitosan, 0.8-1.5 parts of sodium polycarboxylate dispersants, 3-10parts of polyamide, 1-3 parts of acetone and 1-3 parts of N-methylpyrrolidone. The invention further discloses a preparation method of the antifouling coating material for the ship surfaces. The technical problem that the antifouling coating material can not effectively improve the adhesion performance and impact resistance while effectively improving the antifouling performance.

Description

technical field [0001] The invention relates to the technical field of antifouling paint for marine ships, in particular to an antifouling paint for ship surfaces and a preparation method thereof. Background technique [0002] Low surface energy antifouling coatings use the physical properties of low surface energy on the surface of the coating to make it difficult for marine organisms to adhere or not to adhere firmly. When the ship is sailing, it uses the shear force of water or special cleaning equipment to remove the adhesion on the surface of the marine vessel. An antifouling paint for organisms on surfaces. [0003] The invention patent with the authorized notification number CN102337063B discloses a method for preparing a low surface energy ship antifouling coating that can release silicone oil, and also discloses a coating that implements the method for preparing the low surface energy ship antifouling coating that can release silicone oil. The invention The provide...
