Description

Anti-skid wear-resistant coating on surface of ship deck and preparation method thereof

One, the technical field

The invention relates to the field of functional coatings, in particular to an anti-skid wear-resistant coating for the surface of a ship deck and a preparation method thereof.

Second, background Art

With the implementation of the ocean strong strategy in China, more and more large ships are put into use, and particularly the entrance of Liaoning ships greatly enhances the ocean military strength in China. Different from inland environment, marine environment often has high humidity and high salt fog environment, so the material surface is easy to slip and the abrasion is aggravated, the realization of the anti-slip and abrasion-resistant performance of the ship under the marine environment has important significance, and especially the anti-slip and abrasion-resistant performance of the ship deck surface with frequent personnel activities and carrier-borne aircraft operation directly influences the efficiency of the ship. Improving the skid resistance and wear resistance of the surface of the ship deck is a focus of attention of scientific research personnel in related fields in recent years.

Because of the advantages of simple operation, easy maintenance and the like, the method of painting the paint on the surface of the ship deck to form the antiskid wear-resistant coating is the most commonly used method at present. For example, Chinese patent publication No. CN 102477248 discloses a hydroxy acrylic resin coating, which is composed of titanium dioxide, carbon black, lubricant, thickener, anti-settling agent, carborundum, toughening agent, hydroxy acrylic resin anti-slip coating paste and curing agent. Chinese patent (publication No. CN 102504679) discloses a deck anti-slip coating, which mainly comprises: 30-45 parts of emulsion, 2-5 parts of film-forming additive, 15-25 parts of titanium dioxide, 5-20 parts of filler, 0.2-1.0 part of wetting dispersant, 5-15 parts of anti-slip agent, 0.1-0.5 part of defoaming agent, 0.5-1.0 part of anti-aging agent, 0.5-2.0 parts of thickening agent and 0.5-1.0 part of antiseptic and mildew-proof agent; 10-25 parts of water. However, the invention is not popularized and applied in a large scale. Although the MS series of AST company and the Intershield series of international paint company in the United states have been applied to the aircraft decks, the formula of the product is not disclosed or reported due to factors such as confidentiality and the like. Because the coating is complex in composition and various components can generate different influences on the performance of the coating, the anti-skid wear-resistant coating on the surface of the ship deck and the preparation method thereof need to be developed.
