Polypropylene composition for improving surface flame treatment effect and preparation method of polypropylene composition
A polypropylene composition and a flame treatment technology are applied in the polypropylene composition and its preparation, the polypropylene composition for improving the surface flame treatment effect and the preparation field thereof, and can solve the problem that the improvement of the surface energy is not very obvious and the surface energy is not very obvious. It can improve the problems of limited improvement and poor surface flame treatment effect, so as to achieve the effect of good flame treatment surface and adhesive performance, and improve surface tension and wettability.

Example Embodiment
[0045] Compared with Example 1 and Example 4, Example 2 with Example 5, and Example 3 with Example 6, at the same addition amount, the surface contact angle of SBS after flame treatment was smaller , The surface tension is greater and the surface oxygen content is higher.
[0046] Compared with Example 1, in Comparative Example 5, the content of POE is reduced. In the case of the same SBS content, Comparative Example 5 has a better surface treatment effect.
[0047] Compared with Example 4, in Comparative Example 4, the content of POE is reduced. When the SIS content is the same, Comparative Example 4 has a better surface treatment effect.
