Plasticizer composition containing cyclodextrin derivatives, flexible PVC composition with suppression of the migration of plasticizer containing the same, and manufacturing method thereof

摘要

The present invention relates to cyclodextrin derivatives one plasticizer composition, the plasticizer leakage reduction type flexible PVC composition and manufacturing method comprising the introduction of a method for manufacturing a plasticizer leakage reduction type flexible PVC compositions of the present invention (S1) of the cyclodextrin preparing a cyclodextrin derivative having a hydrogen substituted with functional groups in a given compound; (S2) comprising said cyclodextrin derivatives, a mixture of low molecular weight plasticizers for PVC and a liquid to form a plastisol; And (S3) comprises a step of heating and then cooling until the formed plastisol be a solution. The production method of the present invention the liquid phase of the low-molecular-weight plasticizer and to form a complex hameuroseo using a cyclodextrin derivative which is substituted by a given compound as a compound capable of reducing the plasticizer outlet, without using a solvent in a simple and economical way plasticizer It can produce leakage reduction-type soft PVC mass. The prepared soft PVC is reduced the amount of the plasticizer is that even if the leak is hardly lowered physical properties greatly.
