Abstract

The invention provides binary peroxy fluororubber, a preparation method thereof, an intelligent wearable material and a preparation method thereof. Therefore, a technical problem that in the prior art, a wrist strap material and a watchband material cannot well meet the requirements for swimming pool water resistance, sweat resistance, artificial sebum resistance, oleic acid resistance and dirt resistance required by an intelligent wearable wrist strap and watchband at the same time is solved. According to the preparation of the fluororubber, iodine is used as a crosslinking active point; theiodine 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. The polymer used by the invention is used for preparing intelligent wearable materials. The prepared intelligent wearable wrist strap material or watchband material can meet the requirements for swimming pool water resistance, sweat resistance, artificial sebum resistance, oleic acid resistance and dirt resistance, and the prepared intelligent wearable wrist strap or watchband is safe, environmentally friendly, durable, soft in hand feeling, good in texture and comfortable in somatosensory feeling and can better meet the high technical requirement for continuous change of the material of 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 binary peroxide fluororubber and a preparation method thereof, and smart wearable wristband and watchband materials 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. Am...
