Flame retardant plasticized poly(vinyl chloride) film with selective solar spectral transparent properties

Abstract

In this work, some additives were added into plasticized poly(vinyl chloride) (PVC) matrix for the purpose of shielding ultraviolet light (UV), high-energy visible light (HEV) and near-infrared light (NIR). Furthermore, the flame retardance of the plasticized PVC films were also enhanced by adding organo-phosphorus flame retardant plasticizer such as tris(1-chloropropan-2-yl) phosphate (TCPP). The properties of PVC films were investigated by the limiting oxygen index (LOI) test and ultraviolet-visible-near-infrared (UV-vis-NIR) spectrophotoscopy. With the incorporation of Sb 2 O 3 and polyester plasticizer (PEP) into the PVC films, the resultant LOI was increased from 26% (LOI value of PVC with PEP) to 32% (LOI value of PVC with PEP/Sb 2 O 3 ), while the transmittance of visible light decreased from 84.84% to 0.18%. The replacement of PEP in PVC films by TCPP resulted in a significant improvement in flame retardancy. The LOI increased from 26% (LOI value of PVC with PEP) to 35% (LOI value of PVC with TCPP), and the transmittance increased from 84.84% to 91.79%, respectively. Hence, a flame retardant functional PVC film was achieved by the combination of a UV absorber, pigment yellow, TCPP and indium tin oxide (ITO), which possesses a high LOI value (35%), high transmittance in the visible region (81.56%) and low transmittance in the UV region (0.40%), HEV region (62.79%) and NIR region (39.04%).

Tailoring the desired optical and mechanical performance of polyester‐plasticized PVC films: the role of different light stabilizers on the photo‐degradation

“…In our previous work, polyester‐plasticized PVC films with ultraviolet and high‐energy visible (HEV) light shielding performance have been achieved by adding UVAs and pigment yellow (PY) . However, whether these amazing optical performances can be kept after photo‐degradation was still in doubt.…”

In order to prolong the longevity of the polyesterplasticized PVC film with desired performance, HALS together with UVAs were added in this paper.…”

Design and synthesis of a castor oil based plasticizer containing THEIC and diethyl phosphate groups for the preparation of flame-retardant PVC materials

“…An effect way to improve the ame retardancy of PVC materials is to add ame retardants such as antimony trioxide (Sb 2 O 3 ), 14 alumina trihydrate, Al(OH) 3 , 15 or tripentyl phosphate, trimethyl phosphate, tris(chloropropyl) phosphate, and di-noctylphenyl phosphate, 16 but the addition of ame retardants usually decreases the mechanical properties of PVC blends. It is necessary to prepare PVC materials using ame retardant plasticizers that can effectively improve both the mechanical and ame retardant properties of the PVC blends.…”

The effect of OCoAl‐LDH and OCoFe‐LDH on the combustion behaviors of polyvinyl chloride

“…The result is in accordance with the HCl release profile. After Cl was removed, the molecular chains of PVC began to form a reticular structure, which can enhance the heat insulation and the flame‐retardant properties of PVC . Since the EDS scanning is not sensitive of some metal elements, the account for the metal elements is at a low level in the EDS test.…”

“…After Cl was removed, the molecular chains of PVC began to form a reticular structure, which can enhance the heat insulation and the flame-retardant properties of PVC. 23 Since the EDS scanning is not sensitive of some metal elements, the account for the metal elements is at a low level in the EDS test. From the EDS test, it is found that these two kinds of LDH have the catalytic dechlorination effect, which makes…”
