Relationship between Plasticizer Level and Properties of Coating Film

Keyword:  涂料增塑剂自由体积理论;
Abstract: The relation of volume fraction of plasticizer in coating film with the mechanical property was investigated. Experimentally, it was shown that the film possessed optimum impact resistance, flexibility and adhesion when the added plasticizer made the Tg of film- former close to the environmental temperature. It was concluded from free volume theory that the film had good mechanical property when the volume fraction of plasticizer φd met the equation φd (Tgp - T)/(Tgp- Tgd) ,which was also confirmed by experiment.
