Case Study

Combination of Tri(1-Chloro-2-Propyl) Phosphate and Modified Aramid Fiber for Rigid Polyurethane Foam

Xu, Daifang, et al. Polymer Degradation and Stability, 2017, 144, 207-220.

The effects of the combination of tri(1-chloro-2-propyl) phosphate (TCPP) and modified aramid fiber (MAF) on the cell structure and flammability of rigid polyurethane foam (RPUF) were studied. The results showed that the combination of TCPP and MAF can effectively improve the fire resistance of RPUF and ensure the macro-microstructure of RPUF. Compared with the foam without flame retardant, the LOI of PU/TCPP/MAF composites increased by 39.2%, and the MSD, PHRR, PSPR, THR and TSR decreased by 25%, 59.6%, 10.7%, 78.2% and 26.7%, respectively.
Preparation of PU/TCPP/MAF composites
· All the PU foams were produced using a one-shot, free-rise technique with a cast mold. TCPP served as the flame retardant, and AF was modified with phosphoric acid.
· Following the specific formulations, polyether polyol (4110), TCPP, AF, and MAF were pre-mixed at room temperature using an electric stirrer to ensure a homogenous blend. Silicone oil, stannous octoate, triethylenediamine, and polymeric isocyanates (MDI, 5005) were then promptly added to the mixture, which was stirred again at a higher speed for an additional 15 seconds.
· As the mixture expanded, it was quickly poured into an open mold measuring 250 mm x 250 mm x 50 mm to create the free-rise foam. The foams were left to cure at room temperature for 24 hours. After the foaming process, the products were taken out of the mold and cut into specific shapes and sizes according to the relevant testing standards to assess various properties.

Preparation of Tris(1-Chloro-2-Propyl) Phosphate Microcapsule Flame Retardants

Ülkü, Görkem, et al. Polymer-Plastics Technology and Materials, 2021, 60(5), 562-570.

Microencapsulation is an effective strategy to solve the toxicity problem of tris(1-chloro-2-propyl) phosphate (TCPP) liquid flame retardant. In this work, toxic liquid TCPP was microencapsulated with rigid melamine formaldehyde resin and used as a flame retardant additive in polyurethane foam formulation. The results showed that the flame retardant grade of polyurethane foam containing 9 wt% TCPP microcapsules was HB.
Microencapsulation of TCPP
· Melamine-formaldehyde prepolymer (MF) was produced from melamine (7.57 g) and formalin (16.22 g) first and then used to coat the dispersed liquid to provide TCPP coating.
For the microencapsulation process, a 100 ml aqueous solution was prepared by mixing sodium dodecyl benzenesulfonate (SDBS) (1 g) and polyvinyl alcohol (PVA) (0.3 g), which was then added to the prepolymer solution along with TCPP (27.14 g).
· This mixture was stirred for approximately 30 minutes to achieve a stable emulsified solution. The pH of the mixture was adjusted downwards by incorporating a 5 wt% acetic acid solution, the temperature was maintained at 65°C, and the reaction was allowed to proceed for 6 hours while stirring.
· After the reaction was complete, the product underwent washing with water and was then dried at room temperature for 24 hours. The resulting microcapsules were designated as T1. Likewise, microcapsules T2, T3, T4, T5, and T6 were produced using varying stirring rates, SDBS content, PVA content, and different ratios of TCPP to MF.
