Effect of Modified Intumescent Flame Retardant via Surfactant/Polyacrylate Latex on Properties of Intumescent Flame Retardant ABS Composites

Flame retardancy and toughness modification of flame retardant polycarbonate/acrylonitrile-butadiene-styrene/AHP composites

“…However, different processing of the liquid aromatic phosphates and PC/ABS alloy, low Vicat temperature and thermal stability of FR PC/ABS composites limited their application in some electrical fields. In order to improve the thermal distortion temperature and processability of FR PC/ABS composites, silicon-containing FRs and intumescent FRs (IFR) have been also developed as replacements for halogen-containing FRs [7,13e15]; unfortunately, they bring about some disadvantages such as low compatibility with PC/ABS alloy, low water resistance, and low environmental durability in flame retardant PC/ABS composites [16,17]. In addition, the incorporation of a large amount of halogen-free FRs significantly decreases the toughness of thermoplastics.…”

Effect of an Ultrahigh Rubber ABS Impact Modifier Resin on Mechanical Properties of Intumescent Flame-Retardant ABS Composites

“…We have reported that the incorporation of the compounded APP, MA, and CHBPP (that was an unmodified IFR) into ABS caused a great decrease in notched impact strength and the incorporation of the compounded APP, MA, CHBPP with TX-10 phosphate and polyacrylate (that was IFRC) did not increase the boundary adhesion between IFRC and ABS matrix in ABS/IFRC, but it slightly increased the notched impact strength. [14] Here, a superior boundary adhesion mean a strong notched impact strength for the MB method samples owing to the incorporation of UHR-ABS, but the notched impact strength of the MB method samples did not significantly increased compared with ABS/IFRC, the sample which was not filled with UHR-ABS, as shown in Fig. 4c.…”

“…IFR decreases mechanical properties, and a nonsoluble solid state flame retardant in ABS significantly decreases the impact strength, so special treatment is required. [10][11][12][13] In our parallel work, [14] we prepared an IFR composite (IFRC) by compounding APP, MA, calcium 3-hydroxy-2,2-bis(hydroxymethyl) propyl phosphate (CHBPP) with TX-10 phosphate/polyacrylate latex and studied the thermal, processing, and mechanical properties of ABS/IFRC composites. Now we report the effect of an ultrahigh rubber ABS (UHR-ABS) impact modifier resin on the mechanical properties of the ABS/IFRC systems.…”

Halogen-free flame retardants

“…For example, when magnesium hydroxide (MH) was used as the flame retardant of ABS, 60 wt% of MH has to be added to achieve acceptable flame redundancy and, in this case, the impact and tensile strengths of ABS decrease by more than 50%. 7 Furthermore, the large amounts of MH required aggravate particle agglomeration and further worsen polymer mechanical properties. Sze Âp et al 8 studied the effects of MH and montmorillonite (MMT) on the flame retardancy and mechanical properties of ethylene-vinyl acetate copolymer (EVA).…”

“…For example, a polymer nanocomposite containing POSS can obviously reduce PHRR, and enhance LOI. 7 Therefore, the approach of preparing nanocomposites has become another tool for scientists and engineers who are engaged in the research and development of flame-retardant materials. 21 Detailed descriptions about nanotechnology for flame retardation can be seen in Chapters 5 and 6.…”
