TABLE 1 test results of surface polarity and paint film adhesion of each example
From the test results in table 1, it can be seen that with the addition of the polar additive, the surface polarity of the bio-based PE material increases, the adhesion with paint increases, and the painted surface is not easy to fall off. The polar additive is a strong polar substance, and after the polar additive is blended with the bio-based PE, polar groups of the polar additive are gathered on the surface of the bio-based PE material, so that the surface energy of the material can be increased, and the adhesion with paint is further enhanced.
Finally, it should be noted that: the above examples are only used to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
