Abstract

The invention provides ternary peroxide fluororubber and a preparation method thereof, and an intelligent wearable material and a preparation method thereof. The invention aims to solve the technicalproblem that wrist strap and watchband materials in the prior art cannot well meet requirements for swimming pool water resistance, sweat resistance, artificial sebum resistance, oleic acid resistanceand dirt resistance required by intelligent wearable wrist straps and watchbands at the same time. According to the preparation of fluororubber in the invention, iodine is used as a crosslinking active point, iodine used as the crosslinking active point is bonded to the tail end of a fluororubber polymer molecular chain or the tail end of a side chain of a vulcanization point monomer, and vulcanization crosslinking can be easily carried out with peroxide. A polymer prepared in the invention is used for preparing the intelligent wearable material. The prepared intelligent wearable wrist strapmaterial or watchband material can meet the requirements for swimming pool water resistance, sweat resistance, artificial sebum resistance, oleic acid resistance and dirt resistance, and a intelligentwearable wrist strap or watchband prepared from the material is safe, environmentally-friendly and durable to use, soft in hand feeling, good in texture and comfortable in somatosensory feeling and can better meet the high technical requirement for continuous changing of the material for the intelligent wearable wrist strap or watchband.

Description

technical field [0001] The invention relates to the field of fluorine-containing polymer materials, in particular to a ternary peroxyfluororubber and a preparation method thereof, and an intelligent wearable material and a preparation method thereof. Background technique [0002] In recent years, with the advancement of science and technology and the continuous improvement of people's quality of life, artificial intelligence and sports health have rapidly entered the lives of the public, and smart wearable devices have also emerged. Smart watches and smart bracelets have both: traditional watch functions, health monitoring, and intelligent interaction with smart devices such as smartphones. The huge market demand has driven the explosive growth of smart wearable wristbands and strap materials. [0003] Smart wearable wristbands and strap materials need to be safe, environmentally friendly, durable, comfortable, and meet specific functional requirements. Among them, specific...
