Example Embodiment

[0046] Example 1

[0047] 200 parts by weight of TPU carrier resin (Yantai Wanhua), 20 parts by weight of FG1901 (component SEBS-g-MAH, Kraton, USA), 20 parts by weight of anti-wear agent FYTE-68 (component PU), 10 parts by weight of silicone Masterbatch (Dow Corning, USA) and 20 parts by weight of nano-organized montmorillonite DK4 (Zhejiang Fenghong) were pre-mixed in a high stirring pot for 3 minutes, and then sent to a twin-screw extruder with a rotational speed of 300 rpm after mixing uniformly. , the temperature of each screw of the twin-screw extruder is set at 160 ℃, after twin-screw shearing, mixing, extruding, drawing, air-cooling, dicing, and drying from the head to obtain 270 parts by weight of masterbatch, ready for use .

[0048] Fully mix SEBS and filler oil according to the following parts by weight. After the filler oil is completely absorbed by the resin, add mineral filler, add coupling agent during the stirring process, and then add processing aids, stabil...

Abstract

The invention discloses a wear-resistant thermoplastic elastomer, which is prepared from the following raw materials in percentage by weight: 10 to 80 percent of matrix resin, 10 to 60 percent of master batch, 0 to 42 percent of extending oil, 0 to 20 percent of thermoplastic resin, 0 to 30 percent of mineral filler, 0 to 1.5 percent of coupling agent, 0.1 to 2 percent of processing aid and 0.1 to 2 percent of stabilizing agent. The invention also discloses a method for preparing the wear-resistant thermoplastic elastomer. SBS, SEBS and the like are adopted as the matrix resin, and the problem of poor wear resistance of SBC thermoplastic elastomers is solved through improvement of a mixing formular and a process; the prepared thermoplastic elastomer has good wear resistance; compared with the TPU products with good wear resistance, the thermoplastic elastomer has low cost; in the whole process of modifying and producing the material, chemical solvents are not used, the influence on the environment is small, the halogen is free and the environment is protected; and the leftover material of the thermoplastic elastomer can be repeatedly used.

Description

technical field. [0001] The invention relates to the field of polymer materials, in particular to a wear-resistant thermoplastic elastomer and a preparation method thereof. Background technique [0002] Thermoplastic Elastomer (TPE for short), also known as Thermoplastic Rubber (TPR for short), is a kind of rubber that has both rubber and thermoplastic properties. Polymer Materials. Thermoplastic elastomers have a variety of possible structures. The most fundamental one is that there are at least two mutually dispersed polymer phases. At normal use temperature, one phase is fluid (its glass transition temperature Tg is lower than normal use temperature) , the other phase is solid (its Tg is higher than normal use temperature), and there is an interaction between the two phases. This structure gives it mechanical and service properties similar to rubber, as well as the processability of thermoplastics, thus creating a bridge between plastic and rubber. In terms of processi...
