Abstract

The invention discloses solvent-free asphalt paint for an anchor chain for a ship and a preparation method of the asphalt paint. The asphalt paint comprises the following main components in parts by weight: 40-50 parts of modified coal tar asphalt, 20-25 parts of epoxy resins, 10-20 parts of chlorosulfonated polyethylene rubber, 10-15 parts of anthraquinone, 5-10 parts of quartz powder, 10-15 parts of mica powder, 7-10 parts of barium sulfate, 10-20 parts of m-nitrophenol, 20-30 parts of praseodymium trifluoroacetone, 5-10 parts of ethylene glycol, 5-7 parts of acetone, 3-5 parts of lauryl alcohol polyoxyethylene, 5-8 parts of additives and 10-15 parts of an amine curing agent. When the asphalt paint disclosed by the invention is sprayed onto the anchor chain for a ship, a film with extremely high adhesion and high hardness can be formed, the film has excellent seawater corrosion resistance, weather resistance and water resistance, and corrosion and loss of the seawater and the outdoorenvironment to the anchor chain can be alleviated. Moreover, the preparation cost is low, so that the using input is reduced.

Description

Technical field [0001] The invention belongs to the technical field of ship paint, and specifically relates to a solvent-free asphalt paint for ship anchor chains and a preparation method thereof. Background technique [0002] An anchor chain is a chain connecting the anchor and the hull, used to transmit and buffer the external force of the ship, and can also generate a part of the friction. As the ship has been in the marine environment for a long time, seawater corrodes the anchor chain very seriously, and after a period of use, layers of rust spots appear on the anchor chain. In order to protect the structure of the chain and prolong its service life, a layer of paint is usually sprayed on the chain. However, although the anchor chain coatings currently used can play a certain anti-corrosion effect on the anchor chain, the force is limited and the coating is easy to fall off, thus exposing the off part of the anchor chain. [0003] Solvent-free epoxy coal tar pitch paint is a...
