Abstract
The invention relates to the technical field of leather shoe manufacturing, and discloses an anti-tear leather shoe vamp and a preparation method thereof. The anti-tear leather shoe vamp is coated with an anti-tear agent. The anti-tear agent is prepared from the following raw materials in parts by weight: 5-10 parts of hydroxyl silicone oil, 0.5-1.2 parts of a fatting agent, 15-25 parts of acrylic resin, 3-7 parts of epoxy resin, 2-5 parts of a phosphate solution, 0.05-0.2 part of a surfactant and 0.03-0.08 part of an accelerant. The preparation method comprises the following steps of: S1, carrying out surface cleaning on nappa vamp leather for later use; and S2, coating the surface of the cleaned nappa vamp leather with the anti-tear agent, and then drying at 80-100 DEG C to obtain the anti-tear leather shoe vamp. The leather shoe vamp provided by the invention has excellent tear resistance and excellent antifouling performance.
Description
technical field [0001] The application relates to the field of leather shoe manufacturing technology, more specifically, it relates to a tear-resistant leather shoe upper and a preparation method thereof. Background technique [0002] Leather shoes refer to footwear with natural leather as the upper and leather, rubber, plastic, etc. as the sole, processed by gluing, injection molding and other processes. Leather shoes have the characteristics of air permeability and moisture absorption and good hygienic performance, and are one of people's favorite footwear. [0003] Napa shoe upper leather in natural leather has the advantages of lightness, softness and high elasticity, but the current nappa shoe upper leather has poor tear resistance. It is easy to cause the tear strength of the finished product of nappa shoe upper leather to be low, so that the firmness of the finished shoe upper at the seam is low, and it is easy to tear. [0004] In view of the related technologies m...
