Abstract

The invention discloses an enclosure for the bracelet monitoring vital signs and preparation method of the enclosure. The preparation method for the enclosure for the bracelet monitoring vital signs includes: extrusion granulation upon mixing of polypropylene, polyphenylene sulfide, acrylics oligomer, polyethylene wax, emulsifier and stabilizer to prepare master batch M, mixing of the master batchM, fiberglass and sodium dodecyl benzene sulfonate, and extrusion molding for forming the enclosure, wherein the extrusion molding is conducted in the twin-screw extruder, with temperature in loadingarea of the twin-screw extruder of 110-130 DEG C, temperature in the fusion area of 170-200 DEG C, temperature in the mixing area of 210-230 DEG C and temperature in the pressure buildup area of 220-245 DEG C; the enclosure for the bracelet monitoring vital signs solves the problem of breakage, cracking and wear easily of ordinary enclosures of the smart bracelet after using for a long time.

Description

technical field [0001] The field of smart wristbands of the present invention, in particular, relates to a casing for a wristband for monitoring vital signs and a preparation method thereof. Background technique [0002] A smart bracelet is a wearable smart device. Through the bracelet, users can record real-time data such as exercise, sleep and diet in daily life, and synchronize these data with mobile phones to guide healthy life through data. At present, due to frequent use, the shell of the smart bracelet is prone to breakage, cracking, etc., and is also easy to wear. It is difficult for the existing shell to have excellent mechanical properties and wear resistance at the same time. Contents of the invention [0003] The invention provides a shell for monitoring vital signs and a preparation method thereof, which solves the problem that the shell of the smart bracelet is prone to breakage, cracking, etc., and is also easy to wear due to frequent use. [0004] In order...
