Abstract

The invention relates to the technical field of women's shoes, and discloses a leather boot. The leather boot comprises a leather vamp and a sole, wherein the leather vamp is coated with a coating, and the coating comprises the following components in parts by weight: 80-100 parts of acrylic resin, 10-15 parts of polyetherimide, 5-6 parts of nitrile rubber, 3-4 parts of a catalyst, 8-10 parts of polyvinyl alcohol, and 2-4 parts of an auxiliary agent. The leather boot has the following advantages and effects that: polyetherimide is added into the acrylic resin to form a particle dispersion phase, thereby enhancing the toughness of the acrylic resin; under the action of the catalyst, nitrile rubber and acrylic resin react to form an interpenetrating network, and a flexible section is introduced, so that the mobility of a network chain is improved, and the toughening effect is achieved; and the nitrile rubber changes acrylate into a proper net-shaped structure, so that the toughness and weather resistance of the acrylic resin are improved, the toughness and weather resistance of the leather vamp coated with the coating are improved, the situation that the leather vamp cracks in the storage process is avoided, and the service life of the leather vamp can be prolonged.
