SiC fiber reinforced polyurethane series skid-resistant coating and preparation method thereof

Abstract

The invention discloses a SiC fiber reinforced polyurethane series skid-resistant coating and a preparation method thereof. The skid-resistant coating is prepared from a component A, a component B, a component C, and other components through mixing, wherein the component A comprises polytetramethylene ether glycol, liquidated MDI, and E44 type epoxy resin; the B component comprises SiC short fiber, Al2O3 and a surface modifier; the component C comprises liquidated MDI, a chain extender, BaSO4, titanium dioxide and talcum powder; other components comprise a diluent, a defoaming agent and a levelling agent. The preparation method comprises the following steps: all components in the component A are mixed, so that the component A is prepared; all components in the component B are mixed, so that the component B is prepared; the component B, which accounts for 3-8% of the component C is mixed with the component C, and other components are added into the mixture so as to obtain a component D; finally, the component A and the component D are mixed according to the mass ratio of 1: (1-1.1), so that the skid-resistant coating is prepared. The skid-resistant coating disclosed by the invention is high in friction coefficient and adhesive force, excellent in comprehensive performance at low temperature and simple in preparation method.

Description

technical field [0001] The invention relates to an anti-skid coating and a preparation method thereof, in particular to a SiC fiber reinforced polyurethane anti-skid coating and a preparation method thereof. Background technique [0002] Deck anti-slip coating refers to the coating with anti-slip effect on the deck of the ship, which is mainly divided into ordinary deck anti-slip coating and flight deck anti-slip coating. With the increasingly fierce international competition and the continuous development of military high-tech, the tonnage of aircraft carriers and various ships continues to increase, and the rapid development of new carrier-based aircraft has increasingly stringent requirements for the performance and coating process of deck anti-skid coatings. Deck anti-slip coatings have special properties such as anti-skid, wear resistance, and high strength, which can ensure the berthing and safe take-off and landing of carrier-based aircraft, as well as the safety of d...

Problems solved by technology

[0003] Although my country's self-developed deck anti-skid coating has made a major breakthrough, it still cannot meet the current requirements for large-scale ship deck coating.

Especially in the severe winter in the Beihai area, the surface of the shipboard deck will freeze, and the elasticity of the existing polyurethane anti-skid coating will change, which is prone to coating wear; after freezing, the hardness of the paint film increases rapidly, and the anti-skid particles on the surface of the paint film Transforming into a hard contact surface, the sliding of hard materials such as steel on the paint film is a point contact, which in turn reduces the contact surface between the coating and the hard material, resulting in a sharp decrease in friction resistance, and the problem of poor anti-skid effect. Vulnerable to injury from falls on hard, uneven, sharp decks
