preparation example Construction

[0029] The present invention provides a kind of preparation method of leather strap, comprises the following steps:

[0030] S10, providing the leather product body;

[0031] S20, soaking the leather product body in the first treatment agent and the second treatment agent in turn for ultrasonic treatment; and

[0032] S30, drying the soaked leather product body to obtain the leather product;

[0033] Wherein, the first treatment agent is a fluoroacrylate compound with a relative molecular weight of 200-400; the second treatment agent is a fluorocarbon-based trialkoxysilane with a relative molecular weight of 500-800.

[0034] In the preparation method of the present invention, a structurally complete protective layer is formed on the surface of the leather product body, so that the leather product has good water resistance and has excellent antifouling, weather resistance, friction resistance, deodorization and self-cleaning properties.

Abstract

The invention relates to a preparation method of a leather watchband. The preparation method comprises the steps that a leather product body is provided; the leather product body is sequentially soaked in a first treating agent and a second treating agent for ultrasonic treatment; and the leather product body subjected to the soaking treatment is subjected to drying treatment to obtain a leather product, wherein the first treating agent is a fluoroacrylate compound with the relative molecular weight of 200-400; and the second treating agent is fluoroalkyl trialkoxysilane with the relative molecular weight of 500-800. A leather watchband and a watch are disclosed. According to the preparation method, a protective layer with a complete structure is formed on the surface of the leather product body, so that the water resistance of the leather product is relatively high, and meanwhile, the leather product has excellent antifouling, weather resistance, friction resistance, deodorization andself-cleaning performance.

Description

technical field [0001] The invention relates to the field of leather surface treatment, in particular to a leather product and a preparation method thereof, and also to a watch including a leather strap. Background technique [0002] Leather products are very common in daily life, such as leather bags, leather shoes, belts, leather watch straps and so on. During the use of leather products, whether it has water resistance is an important indicator of its performance. In addition, during the production process of leather products, leather usually needs to be processed by sewing, gluing and / or punching to obtain desired leather products. Such treatment has certain damage to the waterproof integrity of the leather strap. [0003] Taking the leather strap as an example, the leather strap is a belt-shaped ornament specially made of genuine leather (cowhide, crocodile skin, etc.) and artificial leather for watches. Generally speaking, a leather watch strap consists of a surface...
