Traditional expansion flame retardant
The traditional expansive flame retardant system mainly includes phosphorus source, acid source and gas source. Traditional expansive flame retardants are composed of polyphosphate (APP), polyols such as PER and melamine (M). When APP heat decomposition, with dehydration effect is generated and pyrophosphoric acid phosphate, the polyol ester, coking, dehydration reaction of water vapor and ammonia together to form a layer of porous carbon layer, make the charcoal fire retardant layer expansion to achieve.
The traditional expansion type flame retardants must have the following properties: a thermal stability is good, and can withstand the high temperature of more than 200 degrees in the process of polymer processing; A large number of volatile substances released by thermal degradation of b are not adversely affected by the expansion foaming process. C is distributed evenly in the polymer, which can form a layer of expansive carbon covering the surface of the material when the material burns. D has good compatibility with PP and does not have any adverse effects on additives, but the physical properties of the materials are much worse.
The advantage of expansive flame retardant is that there is no halogen, no antimony oxide, low smoke, low toxicity, no corrosive gas, and the formation of carbon layer can prevent it from spreading fire.
Dosage of components in the traditional expansion type flame retardant system on the system of flame retardant effect and has a great impact on the processing viscosity of PP, optimize the optimal proportion between components can obtain the best effect of flame retardant, reduce system processing viscosity. M (APP) m (m), m (PER) = (15 ~ 25) (10 ~ 20) (0.5 ~ 1.5) when the flame retardant performance is good, in the traditional expansion type flame retardant different influence on the rheological properties of flame retardant PP, the increased amount of m and the APP will increase the viscosity of flame retardant PP, and an increase in the amount of PER can lower the viscosity of flame retardant PP.
In order to improve the comprehensive performance of traditional expansive flame retardants, some performance defects of various components in traditional expansive flame retardants can be replaced by other materials. For systems containing starch expansion flame retardant PP flame retardant and smoke studies show that the release behavior of starchy expansion flame retardants (S - traditional expansion type flame retardant) can obviously reduce the maximum heat release rate of PP, the average total heat release and effective heat of combustion, show the good flame retardant effect, starch can partially replace PER as in traditional expansion type flame retardant into carbon agent without affecting its flame retardancy.
The formation of expansion carbon layer makes PP thermal degradation rate significantly lower, which is the key to reduce the rate of heat release and the rate of smoke generation. Due to the poor compatibility between traditional expansive flame retardant and PP, and PER the melting in PP processing temperature, the processing performance of flame retardant materials has been affected. Using nylon 6(PA6) instead of parts PER, the traditional expansion flame retardant PP has good mechanical properties and thermal stability. In addition, pa-6eva nanocomposites can improve the combustion and mechanical properties of flame retardant PP.

Due To Excellent Solubility, Improve The Performance Of Many Formulations. In Addition, It Can Be The Final Product It Offers The Following Range Of Interesting Properties Such As Flame Retardancy, Low Temperature Flexibility, Abrasion Resistance, Grease Resistance, Excellent Light Stability And Outdoor Weather Resistance And Excellent High Screen Welding Performance. Due To Its Excellent Solubility, Diphenyl Isooctyl Phosphate (S141, 362, DPOP), And Then 3 Phr Of Bismuth Oxide And 10-20 Phr Of Aluminum Hydroxide Were Added.
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Can Be Used As An Excellent Flame Retardant Material For Transparent Films. In Some Fire-Resistant Harsh Colored Films, It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To Significantly Improve The Light Stability And Outdoor Weather Resistance Of The Film.
(S141,362, DPOP) With Diphenyl Phosphate And Tricresyl Phosphate In The Presence Of 10-15% Of Phthalate Plasticizer Such As DOP, Phosphoric Acid Diphenyl Isooctyl Ester (S141, 362, DPOP) Allows The Resulting Plastic To Have A Low Initial Viscosity And A Good Good False Plasticity And Storage Stability. Due To Its Good Pseudoplasticity And Film-Forming Properties It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To PMMA-Based Plastics And Nitrocellulose Coatings And Inks.
The addition of certain substances to the traditional expansion flame retardant can improve the performance of flame retardant. Formic acid nickel salt as catalyst can effectively improve the flame retardant PP expansion system performance of APPPERM base, catalyst (0.1% ~ 5%) make the system the LOI (limited oxygen index), changed the microcosmic structure of residue, improve the system of thermal stability.
Zinc borate has a synergistic flame retardant effect, which can be formed with traditional expansive flame retardants to form the carbon layer of large bubble hole, which is beneficial to the flame retardancy of PP. Wei ping studied the thermal degradation behavior of 4 molecular sieves in the expansion flame retardant of APPPER and found that after the molecular sieve was added, the heat loss rate of the system decreased, and the heat loss rate peak occurred. It is proved that molecular sieve can be used as the catalyst for the expansion of flame retardant system. It can promote the system crosslinking and carbonation, and improve the flame retardant behavior of the system.
Aimed at the problem of moisture absorption of traditional expansion type flame retardant, LuXiaoMei using ethylene/vinyl acetate copolymer to be coated, microcapsules can not only improve the traditional expansion type flame retardant flame retardant PP moisture resistance, and improved the traditional expansion type flame retardant and the compatibility of PP.

Yukon xiang was synthesized with two kinds of double loop cage phosphate Trimer and PEPA as the base of traditional expansion type flame retardant to flame retardant PP, found that the flame retardant PP compared with pure PP, the heat release rate, total heat release rate and mass loss rate reduced about 70%, 60% and 70% respectively.
In recent years, we have developed another type of non-halogen inorganic expansion system: expanded graphite, which can expand hundreds of times in the high temperature, and has the characteristics of cheap, low smoke and abundant resources.
