- Abstract
Using terephthalic acid and 2-propylheptanol as raw materials, isopropyl titanate as a catalyst, bis(2-propylheptyl) terephthalate(DPHTP)were obtained by esterification. And using DPHTP as a plasticizer to prepare polyvinyl chloride(PVC)flexible film, and compare the application performance with the common DOP and DOTP on the market. The molecular structure of plasticizer was verified by FTIR and 1H-NMR. The differences in mechanical properties of DPHTP, DOP and DOTP plasticized PVC films are compared by TGA, tensile test, migration resistance test and volatility resistance test. The results show that, compared with DOP and DOTP, DPHTP plasticized film has better thermal stability and higher volume resistivity. Respectively, the volume resistivity of DPHTP plasticized film is 6. 5× 109, the 5 % thermal weight loss temperature is 272 ℃, the heating loss of DPHTP is 0. 031 90 %. The conclusion shows that DPHTP has lower volatility and can endow PVC materials with excellent electrical insulation properties, and it was predicted to have broad development prospects in packaging materials and wire and cable industries.
