A preparation method of an elastic material applying TPU is characterized by comprising the following steps:
s1: mixing hydrogenated styrene-butadiene-styrene and processing oil at a low speed and stirring to form a solution A;
s2: adding polyester TPU and polyolefin elastomer into the solution A, and stirring at a high speed to form a solution B;
s3: injecting the solution B into a feeding hopper of a double-screw extruder, extruding the solution B by the double-screw extruder, and cooling and forming.
The invention has the beneficial effects that:
the TPU elastic material is formed by combining hydrogenated styrene-butadiene-styrene, polyester type TPU, processing oil and polyolefin elastomer, the Shore hardness of the prepared TPU elastic material is 65-75A, the melt index is more than or equal to 5g/10min (190 ℃/2.16kg), and the vibration energy can be absorbed, so that the shell can not continuously vibrate on a table top.
