Polyurethane/fluorosilicone rubber thermoplastic elastomer for wearable devices and preparation method thereof

Abstract

The invention discloses a polyurethane / fluorosilicone rubber thermoplastic elastomer for wearable devices and a preparation method thereof. The polyurethane / fluorosilicone rubber thermoplastic elastomer for wearable devices includes Saturated double-bond mixing type thermoplastic polyurethane and fluorosilicone rubber; and the following components based on the total mass percentage of polyurethane / fluorosilicone rubber thermoplastic elastomer: 1-10% of unsaturated double bond-containing mixing type polyurethane elastomer , catalyst 0.1-1%, inhibitor 0.1-1%, antioxidant 0.01%-5%, light stabilizer 0.05%-3%, hydrolysis stabilizer 0.05%-5%, and hydrofluorosilicone oil crosslinking agent. The invention combines the durability, wear resistance and injection molding properties of TPU with the high and low temperature softness and UV resistance of fluorosilicone rubber, and has the characteristics of water and oil repellency, which can significantly improve the comfort of the body, and has good Cost-effective, it can better meet the increasing requirements of wearable devices for materials.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polyurethane / fluorosilicone rubber thermoplastic elastomer for wearable devices and a preparation method thereof. Background technique [0002] Wearable devices were originally represented by smart watches and fitness tracker bracelets. With the development of sensor technology, wearable devices have derived many new categories, such as Shoes, Glass, accessories and medical care. The requirements for materials of wearable devices are also increasing day by day. Because they are close to the skin, they are required to be harmless to human skin and health, comfortable in body, good in soft touch, good in durability and wear resistance, and high in cost performance. At present, the materials suitable for wearable devices mainly include: TPU, TPSiV, fluororubber, TPES, etc. Among them, TPU material is the most suitable for comprehensive performance and cost performance. TPU material ...
