Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of polyurethane topcoat, and in particular relates to a permeable floor polyurethane topcoat and a preparation method thereof. [0003] 【Background technique】 [0004] Polyurethane topcoat is a two-component polyurethane anti-corrosion topcoat composed of synthetic resin as base material, coloring pigment and curing agent. Polyurethane topcoat has good chemical resistance and water resistance, and the formed paint film is tough and glossy. It is widely used on floors and automobile surfaces. When the polyurethane topcoat is applied to the floor area with heavy traffic, it needs to have good abrasion resistance, otherwise it will be easily scratched by tires and heels. [0005] The Chinese patent document "A Modified Polyurethane Topcoat (Application Publication No.: CN107573829A)" discloses a modified polyurethane topcoat comprising the following components by mass fraction: 20-40% of hydroxyl acryl...
