The characterization result of table 1 plastic film I to plastic film XVIII
As shown in Table 1, different amounts of montmorillonite is added in embodiment one to embodiment five, it is de- is only prepared for PVA/ illiteracies Native film, when mixing the amount of montmorillonite of PVA in 1-5phr, tensile strength, elongation at break gradually increase, when montmorillonite exists When 5-9phr, tensile strength, elongation at break are all gradually reduced；Different amounts of cover is added in embodiment six to embodiment ten to take off Soil is prepared for PVA/ starch/montmorillonite tri compound film, with the increase of montmorillonite content, the tensile strength of composite membrane and Incremental trend is totally presented in elongation at break；Not montmorillonoid-containing is only prepared in embodiment 11 to embodiment 15 to add Add the PVA/ starch films of object；Embodiment 16 to embodiment 18 is added on the basis of embodiment 11 to embodiment 13 Add the montmorillonite of 1phr as additive, is prepared for tri compound film.It is added to the composite membrane after the montmorillonite of 1phr, Tensile strength and elongation at break are better than the PVA/ starch films without additive.
According to embodiment one to embodiment 17 it is found that the plastic film being prepared using montmorillonite is for petroleum base Plastic material has alternative well.Compared to the plastic film not containing montmorillonite, with the addition of montmorillonite, plastics The tensile strength and elongation at break of film get a promotion.The reason is that with the addition of montmorillonite, tensile strength increases main It is due to by forming strong interaction of the hydrogen bond between hypothallus and silicate layer.And montmorillonite filler can lead to The regularity that release effect improves interchain arrangement is crossed, keeps interchain smoother, water-wet behavior also acts the elongation for improving PVA Important role.
Therefore, tensile strength, elongation at break and water absorption rate are considered, when modified montmorillonoid content is 9phr, PVA Starch ratio is 1:The effect of the plastic film prepared when 1 is best.
The effect of embodiment
According to a kind of method producing high performance plastic film using montmorillonite involved in the present embodiment.Using illiteracy De- soil by mixing, stirring, heating, drying, removes these processes and obtains plastic film, and the technological process of this method is simple, Processing time is short.In addition, using montmorillonite for raw material, biodegradable starch material and polyvinyl alcohol are taken full advantage of, is tied It closes modified montmorillonoid and improves its mechanical performance, can effectively substitute traditional petroleum-based plastics, not only environmentally protective, Er Qieneng Create prodigious economic benefit.
