| Abstract: | With reproducible calcium lignosulfonate and PVA as primary material,the film of good mechanical properties was synthesized.The effects of different factors on the tensile strength,elongation at break and water-absorption rate of composite film were studied by single factor experimentation.It was found that formaldehyde,urea and borax had playied a role in tensile strength and water-absorption rate.The optimal condition for the film with comprehensive property as follows: formaldehyde content 10g,urea content 7g,borax content 2.5g. |
