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.
