Abstract

The invention relates to the technical field of women's shoes, and discloses a leather boot, which includes a leather upper and a shoe sole. The leather upper is coated with a paint, and the paint includes the following components in parts by weight: 80-100 parts of acrylic acid Resin; 10-15 parts of polyetherimide; 5-6 parts of nitrile rubber; 3-4 parts of catalyst; 8-10 parts of polyvinyl alcohol; 2-4 parts of additives. The present invention has the following advantages and effects: polyetherimide is added to acrylic resin to form a dispersed phase of particles, which improves the toughness of acrylic resin; under the action of a catalyst, nitrile rubber reacts with acrylic resin to form an interpenetrating network, and introduces a flexible segment , improve the mobility of the network chain, to achieve the toughening effect; nitrile rubber changes the acrylate to a moderate network structure, improves the toughness and weather resistance of the acrylic resin, and is beneficial to improve the toughness of the leather upper after coating And weather resistance, thereby avoiding the cracking of the leather upper during storage, which can prolong the service life of the leather upper.

Description
