Preparation and Properties Research of Anti-fogging Polypropylene Packaging Films
The anti-fogging properties of a new anti-fogging agent containing silicon sprayed on polypropylene were discussed.The anti-fogging agent was prepared by using silicone hydride and silica sol,the new anti-fogging agent with different consistency was daubed on the polypropylene film.The contact angle,first dripping time and ten drippings time of the anti-fogging PP films were tested.According to the range analysis,the best mixture ratio,which was just the optimum formula was found.The relationship between the anti-fogging agent consistence and the anti-fogging performance was discussed too.The result showed that the anti-fogging properties of the coated film were better and the mechanical properties of the coated film enhanced in some sort.The mixture ratio of the anti-fogging agent was that the silica sol was 12phr; the span 80 was 15phr; the pH was 5.5.Aiter the film was coated,the tensile strength of machine direction raised by 109.14% than the contrast.The elongation at break of transverse direction raised by 32.51% and that of machine direction raised by 17.95%.This anti-fogging agent containing silicon was preferable to polypropylene.
