Abstract

The invention provides a triethylene tetramine modified resin film and a preparation method thereof, and relates to the technical field of high molecular materials. The high-contractility environment-friendly resin film comprises the following raw materials: terephthalic acid, triethylene tetramine, glycol, dicyclohexylcarbodiimide, 1-hydroxybenzotriazole, nanometer silicon dioxide and a mixed catalyst, wherein the mass ratio of the terephthalic acid to the triethylene tetramine is 100:(15-30); the preparation method comprises the following steps: S1, preparing the raw materials; S2, performing esterification, acid activation and polymerization reaction; S4, performing extrusion, quick chilling, preheating and biaxial stretching, so as to obtain the triethylene tetramine modified resin film. The resin film is high in hot-shrinkage rate and good in wear resistance, and the preparation method is simple, high in efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a triethylenetetramine-modified resin film and a preparation method thereof. Background technique [0002] Heat shrinkable film is widely used in the construction industry and packaging industry due to its certain shrinkage, but the shrinkage characteristics of the heat shrinkable film currently used are not ideal. In order to improve the shrinkage characteristics of the heat shrinkable film, many researchers use a multilayer structure. The mode of extruding is realized, as Chinese Patent Authorization Announcement No.: CN100484757C, discloses a kind of high-barrier high-shrinkage film with polyvinyl alcohol as the middle layer and its preparation method. The structure of the film in this patent is 3 to 7 layers, with Achieve high barrier and high shrinkage characteristics; Chinese patent authorization announcement number: CN 102285173B, discloses a low-density high-shr...
