Flame-retardant ABS resin was prepared by adding fl ame retardant, toughening agent and dispersing silicone oilwith acrylonitrile-butadiene-styrene resin (ABS, grade 0215 A) as raw material. The results showed that in the ABSresin, fl ame retardant with tetrabromobisphenol A and antimony trioxide as the composite system (the mass ratio of2:1) was added. When the bromine content of the system was more than 10%, the flame retardant ABS meets therequirements of UL 94 V-0. The best toughening agent for flame retardant ABS resin is ABS graft powder. Whenthe amount of fl ame retardant ABS is 9% ~ 19% (mass fraction) Strength of 150-200 J / m; in the same formula andoperating conditions, brominated alkylene oxide as fl ame retardant prepared fl ame retardant ABS resin, the weatherresistance is better than tetrabromobisphenol A as fl ame retardant The Composite expansion fl ame retardant and coatedred phosphorus is an eff ective halogen-free fl ame retardant.

Epoxy-functionalized ABS-g-GMA powder was prepared with polybutadiene as core and styrene-co-acrylonitrile-co-glycidyl methacrylate as shell. The ABS-g-GMA powder, styrene-co-acrylonitrile copolymer (SAN) and triphenyl phosphate (TPP) was melt blended together and halogen-free flame-retardant ABS resin was prepared. The research found that when the content of TPP was 20wt%, the epoxy-functionalized ABS resin (eABS) showed much higher thermo-stability than the ordinary ABS resin. The burning rate of eABS decreased from 35mm/min to 8.6mm/min, mass loss rate decreased from 25%/min to 10%/min and limit oxygen index increased from 22% to 28%. FTIR showed that the chemical reactions took place between eABS and the decomposition products of TPP. The tensile tests and impact test found that the eABS/TPP samples showed higher elastic modulus, tensile strength and impact strength than ABS/TPP samples.

Abstract A thorough study was carried out to investigate the priority of a novel co-rotating non-twin screw extruder (NTSE) over a traditional twin screw extruder (TSE) in the mixing process of halogen-free intumescent flame-retardant acrylonitrile-butadiene-styrene (ABS) composites. The homogeneity of the flame-retardant additives of the composites processed by NTSE and TSE under the same operating conditions was characterized by using mechanical performance properties, limiting oxygen index values, UL-94 tests, and thermogravimetric analysis. All the results suggested that NTSE could achieve better mixing of the flame-retardant additives in the polymer matrix than TSE, which was further clarified by the scanning electron microscope pictures.

In order to find an effective halogen-free flame retardant for acrylonitrile-butadienestyrene copolymer (ABS), organo-phosphorus compounds were studied and their flame retarding performances were determined by UL 94 vertical test. It is found that the flame retardancy strongly depends on phosphorus (P) content of organophosphorus compounds. Only the mixture of ABS with 2-(6-oxido-6Hdibenz< c,e><1,2>oxaphosphorin-6-yl) methyl diethyl phosphinate (ODOPM-DE), which has the highest P content, i.e., 17.68 % gives V-0 rating for the 70/30 composition.

Acrylonitrile-butadiene-styrene (ABS) was treated with various formulations containing an intumescent fire retardant, which consists of ammonium polyphosphate (APP) and a novel char-forming agent, poly(diphenolic phenyl phosphate)(poly(DPA-PDCP)). The behaviour of this intumescent system was investigated by thermogravimetric analysis (TGA), LOI test and cone calorimeter test, respectively. The results showed that the addition of poly(DPA-PDCP) enhanced the thermal stability and flame retardancy of ABS/APP. The weight of residues improved with the addition of poly(DPA-PDCP) . SEM investigations of residual char burning after cone calorimeter test revealed that poly(DPA-PDCP) plays an stimulative role in the process of carbonization. The intumescent chars formed from ABS/APP/ poly(DPA-PDCP) composites were intact and strong. It is confirmed that the poly(DPA-PDCP) is an efficient char-forming agent for flame retardant ABS resin.

Wood-plastic composites (WPC), a fast growing class of material used by the furniture and building industry for its excellent mechanical performance and functionality. However, WPC is easily combust because the raw material of it, i.e. wood and plastic burns so easily which result in more fire dangers of WPC. Unfortunately, in the case of WPC, few researchers have carried out to reduce its flammability which still has a long way to go. In this paper, the current development of halogen-free flame retardant WPC at domestic and abroad was reviewed. Especially, the fire retarded WPC with phosphorus, nitrogen, boron, silicon and other flame retardant elements, the fire retarded mechanism, the problems, such as poor compatability, bad resistance to heat and limitation of wood adding quantity, and the solution to the problems were emphasized.

Ammonium polyphosphate have six crystalline forms, of them, form I and form II have industrial uses, their flame retardant properties have been studied extensively. Form V is seldom studied, its flame retardant is not fully known. In this paper, the flame retardant effects of ammonium polyphosphate with crystalline form II (APP-II) and crystalline form V (APP-V) in polypropylene were tested. Results show that the flame retardant effect of APP-V is better than APP-II, and has better mechanical strength that APP-II, meaning it should has a good market perspective in field of halogen-free flame retardation.

A novel phosphorus-silicon containing flame-retardant DOPO-V-PA was used to wrap carbon nanotubes (CNTs). The results of FTIR, XPS, TEM and TGA measurements exhibited that DOPO-V-PA has been successfully grafted onto the surfaces of CNTs, and the CNTs-DOPO-V-PA was obtained. The CNTs-DOPO-V-PA was subsequently incorporated into epoxy resin (EP) for improving the flame retardancy and dispersion. Compared with pure EP, the addition of 2 wt% CNTs-DOPO-V-PA into the EP matrix could achieve better flame retardancy of EP nanocomposites, such as a 30.5% reduction in peak heat release rate (PHRR) and 8.1% reduction in total heat release (THR). Furthermore, DMTA results clearly indicated that the dispersion for CNTs-DOPO-V-PA in EP matrix was better than pristine CNTs.
