A kind of women's shoes with anti-cracking vamp and its preparation method

Abstract

The application relates to the field of shoes, and discloses a women's shoe with an anti-crack vamp and a preparation method thereof. A women's shoe with an anti-cracking vamp, including a vamp and a sole, a flax fiber layer is bonded to the lower surface of the vamp, and a coating agent is coated on the upper surface of the vamp, and the coating agent includes the following parts by weight Raw materials: 40-50 parts of polybutylene terephthalate; 5-8 parts of phenylenediamide phthalamide; 3-4 parts of dicyclopentadiene; 1-2 parts of cross-linking agent; the preparation method is: S1. Preparation of coating agent; S2. Surface coating of shoe upper; S3. Women's shoe molding; The advantages of this application are: phenylenediamide and dicyclopentadiene are cross-linked to form a cross-linked network, and then combined with thread Blending of polybutylene terephthalate, so that polybutylene terephthalate randomly penetrates into the cross-linked network, can form a dense and loose two-phase network structure, and destroy the uniformity of the cured network , which is conducive to stress dispersion, which can play a toughening role and improve the anti-cracking performance of the upper.

Description

technical field [0001] The present application relates to the field of shoes, in particular to a women's shoe with an anti-crack vamp and a preparation method thereof. Background technique [0002] Shoes are a necessary daily necessities in people's daily life; most of the current shoe uppers are made of PU material. [0003] At present, the patent with the notification number CN205682576U discloses a shoe, which includes a sole, an upper and an upper. There are several stripes and some massage bumps on the palm of the insole, and some leakage holes on the heel of the insole. The sole, upper and upper are all made of PVC or PU foam material, which is a dissipative material. [0004] The above-mentioned existing technical solutions have the following defects: during the wearing process of the shoes, since the upper will be directly exposed to the external environment, it will be exposed to the sun for a long time, and it will also be squeezed by the movement of the feet.
