Abstract

The invention belongs to the technical field of modification of elastomer materials, and provides a pollution-resistant elastomer compound and its preparation method and application; the elastomer compound is prepared from the following components by weight percentage, each weight percentage below The total weight of each component is 100wt%: 30-70wt% thermoplastic polyurethane elastomer, 5-40wt% thermoplastic polyester elastomer, 5-40wt% thermoplastic copolymer containing acrylonitrile comonomer. The preparation method comprises: premixing each component to obtain a premixed material, and then extruding and granulating the premixed material with a twin-screw extruder to obtain the elastomer compound. The stain resistance of the resulting elastomeric compound was greatly improved while retaining the elasticity, abrasion resistance and hand of TPU.

Description

technical field [0001] The invention belongs to the technical field of modification of elastomer materials, and in particular relates to a pollution-resistant elastomer compound and its preparation method and application. Background technique [0002] With the advancement of technology, wearable devices have been greatly developed and have become an indispensable part of many people's daily lives. A smart bracelet is a widely used wearable smart device. Through a smart bracelet, users can record real-time data such as sleep, diet, and exercise in daily life, thereby playing a role in guiding a healthy life. [0003] TPU is a thermoplastic elastomer material with excellent elasticity and wear resistance, soft texture, and good molding processability; therefore, it has great potential for preparing smart bracelets. However, the extremely poor stain resistance of TPU limits its wide application in the field of smart bracelets. [0004] At present, the main method to improve t...
