[0049] Each component was mixed according to the formula amount of Examples 1-4, and a TPV film was obtained by calendering.
[0050] The TPV film is either not subjected to radiation cross-linking treatment, or is subjected to positive mold molding after radiation cross-linking with 10kGy, 60kGy, 130kGy, or 200kGy. The molding effect, surface pattern, and tensile strength change of the obtained film (compared with the sample without radiation treatment as 100%) were compared, and the results are shown in Tabl...
Embodiment 5
[0055] A TPV material for automobile interior decoration, comprising 100 parts by weight of TPV and 1 part by weight of a crosslinking agent.
[0056] The preparation method of above-mentioned TPV material is:
[0057] (1) Obtain TPV film by calendering;
[0058] (2) Carry out surface embossing and surface coating treatment processes on the TPV film obtained in step (1), and then use electron beams to perform radiation crosslinking. The radiation dose of the electron beams is 200 kGy to obtain the TPV material for automotive interior decoration.
Embodiment 6
[0060] A kind of TPV material for automotive interior, comprising by weight parts:
[0061]
[0062] The preparation method of above-mentioned TPV material is:
[0063] (1) Obtain TPV film by calendering;
[0064] (2) Carry out surface embossing and surface coating treatment processes on the TPV film obtained in step (1), and then use electron beams to carry out radiation crosslinking. The radiation dose of electron beams is 1 kGy to obtain the TPV material for automotive interiors.
