Abstract

The application relates to the field of leather shoe manufacturing technology, and specifically discloses a tear-resistant leather shoe upper and a preparation method thereof. The tear-resistant leather shoe upper is coated with a tear-resistant agent, and the raw materials for the preparation of the tear-resistant agent, in parts by weight, include 5-10 parts of hydroxy silicone oil, 0.5-1.2 parts of fatliquor, and 15-25 parts of acrylic resin. parts, 3-7 parts of epoxy resin, 2-5 parts of phosphate solution, 0.05-0.2 part of surfactant, 0.03-0.08 part of accelerator; its preparation method is: S1, take nappa shoe upper leather for surface cleaning and standby ; S2, coating the anti-tear agent on the surface of the cleaned nappa shoe upper leather, and then drying at 80-100 ° C to obtain the anti-tear leather shoe upper. The leather shoe upper of the present application has excellent tear resistance and excellent antifouling performance.

Description

technical field [0001] The present application relates to the field of leather shoe manufacturing technology, and more particularly, to a tear-resistant leather shoe upper and a preparation method thereof. Background technique [0002] Leather shoes refer to the footwear that uses natural leather as the upper and leather, rubber, plastic, etc. as the sole, and is processed by gluing, injection molding and other processes. Leather shoes are breathable, hygroscopic and have good hygienic properties, and are one of the most popular footwear. [0003] The nappa 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 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 above-mentioned related technologies, the i...
