Water-based salt-fog-resistant marine coating and preparation formula thereof

Abstract

The invention discloses a water-based salt-fog-resistant ship coating and a preparation formula of the water-based salt-fog-resistant ship coating. The coating is prepared from the following raw material components in parts by mass: 25 to 35 parts of deionized water, 20 to 25 parts of acrylic resin, 10 to 15 parts of vinyl acetate, 2 to 4 parts of waterborne epoxy emulsion, 1 to 2 parts of a waterborne epoxy curing agent, 1 to 2 parts of an ultraviolet absorbent, 1 to 3 parts of a defoaming agent, 5 to 10 parts of a filling agent, 3 to 7 parts of a neutralizing agent, 1 to 6 parts of a thickening agent, 1 to 3 parts of coalescing agent, 2 to 6 parts of a waterborne antirust agent and 3 to 9 parts of a salt spray resistant additive. Instruments and equipment required for preparing the water-based salt-fog-resistant ship coating comprise a stirring tank, a stirrer and a filter. The water-based salt-fog-resistant ship coating has the advantages that the salt-fog resistance is enhanced, the ship surface which is frequently contacted with seawater is prevented from being corroded by chlorides, the influence of the chlorides on the service life of the ship is reduced, the economic loss of a user caused by the damage of the ship surface is avoided, and the water-based salt-fog-resistant ship coating is green and environment-friendly and conforms to the green industrial development concept.

Description

technical field [0001] The invention relates to the technical field of marine coatings, in particular to a water-based salt-spray resistant marine coating and its production formula. Background technique [0002] Ship paint refers to the paint used on the surface of ships and marine machinery and equipment. It is composed of a series of paints such as ship primer, antirust paint and antifouling paint to protect the surface of ships and machinery. The surface of ships and other equipment will not only cause damage to the equipment but also increase the energy consumption of the equipment. Therefore, ship coatings also have the function of preventing marine organisms from adhering, and because the working environment of ships and other equipment is harsh, the durability of ship coatings is compared to other coatings. It has also greatly increased. With the advancement of science and technology, the development of marine coatings is also changing with each passing day. Water-ba...
