preparation example Construction

[0029] The present invention provides a method of preparing a leather strap, comprising the steps of:

[0030] S10 provides a leather product body;

[0031] S20, the leather article body is sequentially immersed in the first treatment agent and the second treatment agent; and

[0032] S30 will dry treatment after the soaking treatment of the leather article body is dried to obtain the leather article;

[0033] Among them, the first treatment agent is a fluoroacrylate compound having a relative molecular weight of 200 to 400; the second treatment agent is a fluorocarbon-based trikoxysilane having a relative molecular weight of 500 to 800.

[0034] The preparation method in the present invention forms a structure intact protective layer on the surface of the leather article body, so that the waterproof resistance of the leather article is good, and there is excellent antifouling, weather resistance, friction, deodorizing, self-cleaning performance.

Abstract

The invention relates to a method for preparing a leather watch strap, comprising the following steps: providing a leather product body; sequentially soaking the leather product body in a first treatment agent and a second treatment agent for ultrasonic treatment; and soaking the leather product body The leather product body is dried to obtain the leather product; 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 , the relative molecular weight is 500-800. The invention discloses a leather watch strap and a watch. 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.

Description

Technical field [0001] The present invention relates to the field of leather surface treatment, and more particularly to a leather article and a preparation method thereof, further involves 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 straps, etc. During the use of leather products, whether it has an important indicator of waterproofness is a performance and disadvantage. In addition, leather products are in the production process, and leather usually requires sewing, adhesive and / or punching, etc. to obtain the desired leather article. Such treatments have certain damage to the integrity of the leather strap waterproof. [0003] Taking the leather strap as an example, the leather strap is a special leather (cowhide, crocodile skin, etc.) and a strip ornament prepared by artificial leather. In general, the leather strap is contained by the face layer (usually ...
