(Note that the larger the breaking strength, the larger the adhesion, the smaller the breaking strength, the smaller the adhesion, the smaller the abrasion resistance, the better the abrasion resistance, the larger the abrasion resistance, the worse the abrasion resistance.)
The comparison between the comparative example 1 and the example 2 shows that the adhesion, the wear resistance, the salt water resistance, the artificial weather aging resistance and the skid resistance of the example 1 are all better than those of the example 2, because in the example 1, the zirconium oxide is added when the bisphenol A diglycidyl ether is subjected to interpenetrating network polymerization in the polyurea microcapsule-polyurethane, the zirconium oxide is wrapped by a compact network structure, so that the zirconium oxide is tightly combined with the coating, and meanwhile, the zirconium oxide has excellent chemical and physical properties, such as salt water corrosion resistance, high strength and high toughness, and is solid insoluble in the coating, and can be used as a skid-proof filler of the coating, so that the related chemical and physical properties of the coating are improved. Compared with the embodiment 3, the difference is that the bisphenol A diglycidyl ether is not added in the embodiment 3, the adhesion, the wear resistance, the aging resistance and the skid resistance of the coating of the embodiment 2 are better, the interpenetrating network polymerization possibly occurs in the bisphenol A diglycidyl ether and the polyurea microcapsule-polyurethane, so that the coating structure is more compact, the wear resistance, the aging resistance and the skid resistance of the coating are enhanced, the bisphenol A diglycidyl ether contains ether bonds and hydroxyl groups, the bonding with deck metal is facilitated, and the adhesion of the coating on a deck is improved.
The comparison between the example 3 and the example 4 shows that the wear resistance of the example 3 is slightly better than that of the example 4, and the salt water resistance and the skid resistance are obviously better than those of the example 4, because the polyurea microcapsule of the example 4 is not coated with boron phosphide, the main crystal form of the boron phosphide is a cubic crystal form, the polyurea microcapsule has good mechanical properties and stable chemical properties, is seawater corrosion resistant and has high hardness, and the polyurea microcapsule is embedded into an interpenetrating network structure in the example 3, so that the wear resistance and the skid resistance of the coating are enhanced, and the salt water resistance of the coating is improved. Comparing example 4 with comparative example 1, comparative example 1 is a pure polyurea-polyurethane structure, the wear resistance, the anti-human aging property and the skid resistance are all reduced compared with example 4, there is no microcapsule embedded in comparative example 1, the coating structure is not stable and compact as in example 4, and the microcapsule can be used as a skid-proof filler, thereby improving the wear resistance, the anti-human aging property and the skid resistance of the coating.
