Antifouling treatment method for watchband material

Abstract

The invention belongs to the field of material treatment, and particularly relates to an antifouling treatment method for watchband material. The method comprises following steps: A, the surface of abase material is subjected to ultraviolet treatment in an ozone environment; B, the base material obtained by treatment in the step A is subjected to enhanced ultraviolet treatment in the ozone environment; C, the base material obtained by treatment in the step B is subjected to normal-pressure plasma treatment, and the watchband material is obtained. According to the method, the material surfaceis treated with ultraviolet and plasma technologies, hydrophility and antifouling property of the material are changed, and compared with a surface spraying treatment technology with the problem of poor antifouling property caused by coating wear and falling-off, the method has the advantages that properties such as hand feeling and the like of the base material are not affected and other properties of the base material are retained continuously in a process of improving the antifouling property.

Description

technical field [0001] The invention belongs to the field of material treatment, and in particular relates to a treatment method for watchband material which is resistant to dirt. Background technique [0002] With the development of science and technology, smart wearable devices have been widely promoted and applied, such as bracelets, watches, VR glasses, etc. are in a stage of vigorous development. Thermoplastic elastomer materials have excellent mechanical properties and elasticity, and are currently the preferred materials for smart wearable devices. However, as consumers have increasingly stringent requirements on the functionality and comfort of materials, pure thermoplastic elastomer materials can no longer meet the ever-changing and demanding requirements, such as dirt resistance and silky feel.

Problems solved by technology

However, as consumers have increasingly stringent requirements for material functionality and comfort, pure thermoplastic elastomer materials can no longer meet the ever-changing and demanding requirements, such as dirt resistance, silky feel, etc.

At present, low surface energy materials such as thermoplastic silicone polyurethane elastomer, fluororubber, etc. are generally used to improve the requirements of dirt resistance. However, the cleaning effect of fluororubber on ink and other substances is still biased. In order to meet the harsh dirt resistance of materials It is required that technicians use surface spraying to process materials such as watch straps. Although the dirt resistance of watch straps can be improved to a certain extent, the surface spraying process is difficult to operate and has an impact on the feel of the base material and requires Benzene, ketone and other organic solvents, and the watchband material obtained by surface spraying process is easy to wear and fall off after a short period of use, and the dirt resistance performance will deteriorate with the destruction of the coating

Therefore, there is still no technical means that can permanently improve the dirt resistance of materials such as watch straps.
