preparation example Construction

[0038] Yoga stick of the present invention is prepared by following preparation method, wherein, preparing mandrel 2 comprises the steps:

[0039] A. Mix high-pressure low-density polyethylene (LDPE) resin 100, foaming nucleating agent 0.2-10 and pigment 0.1-10 evenly, then add plasticizer and stir;

[0040] B. Plasticize in a foaming machine at 170°C-250°C for 3-10 minutes, then inject the sizing agent through the high-pressure reciprocating pump of the metering plunger, and then inject butane gas through the high-pressure reciprocating pump of the metering plunger for foaming. 70 ℃ - 95 ℃ foaming machine uniformly mixed into a mixture;

[0041]C. The mandrel 2 is extruded and foamed through the die opening of the die head at 80°C-120°C, and cut to length when it is stably cooled to 10°C-50°C to obtain mandrels 2 of different lengths, Then the mandrel 2 is placed under natural conditions to harden.

[0042] Yoga stick of the present invention is prepared by the following pr...
