Polypropylene flame retardant
Polypropylene (PP) is a kind of general plastic, because of its processing convenience, mechanics, electric insulation, and excellent chemical resistance, non-toxic, small density, light quality, etc and are widely used in automobiles, household appliances, textile, construction and other industries. However, because the polypropylene oxide index is low, it is easy to burn, and it burns a lot of heat, producing a lot of molten droplets, which can easily spread flame, so the application in many fields is limited.
At present, the flame retardant method of polypropylene is mainly added flame retardant method. This method is simple and easy to use, and the type of flame retardant which can be used is much, and the cost is low, which is the main preparation method of flame retardant polypropylene. This paper summarizes recent research progress of polypropylene flame retardant in China and abroad.
The flame-retardant mechanism of polypropylene flame retardants is roughly divided into the following categories:
a. interrupt chain reaction and terminate the free radical chain reaction of polypropylene combustion. If the halogen flame retardant is decomposed at a higher temperature, the HX can be released, and the free radicals generated during the combustion of polypropylene can be captured by HX, and the flame retardant chain reaction is achieved.
B. The heat generated from the pyrolysis of polypropylene is reduced and the system temperature is reduced. An inorganic flame retardant for aluminum hydroxide and boric acid.
C. The concentration of flammable substances and the concentration of oxygen can be reduced to below the fire limit. D. Promote the formation of carbon and reduce the generation of flammable gases. On the surface of the material, it forms an expansive porous homogeneous carbon layer, which ACTS as an insulating, oxygenated, smokeless and anti-droplet to achieve the flame retardant. Phosphorus and expansive flame retardant are mainly the flame retardant mechanism.
The flame-retardant mechanism of polypropylene flame retardants is often applied to compound flame retardants such as antimony - halide, phosphorus - halide, phosphorus-nitrogen synergistic system.
Inorganic flame retardants are non-toxic, thermal stability, and smokeless. When heated, water is released and a large amount of heat is absorbed. The resulting water vapor can dilute the flammable gas concentration and isolate the air. The resulting water-resistant metal oxide forms a solid protective layer to prevent the combustion reaction from continuing. The disadvantage is that the addition quantity is larger, and the polypropylene lacks the affinity, the dispersion, the compatibility is poor, the material mechanical property declines. The superfine and surface treatment of inorganic flame retardant particles can be enhanced with the interface of polypropylene.

Diphenyl Isooctyl Phosphate (S141,362, DPOP) Product Overview
Chemical Classification: Diphenyl Isooctyl Phosphate, Diphenyl 2-Ethylhexyl Phosphate
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Is An Excellent Flame Retardant Plasticizer That Can Be Used In Most Industrial Polymers Including PVC And Its Copolymers, Nitrocellulose, Ethylcellulose, Poly Methyl Cellulose Methyl Ester, Polystyrene And The Like. Diphenyl Isooctyl Phosphate (S141,362, DPOP) Are Generally Used In The Manufacture Of Vinyl Sheets, Coated Fabrics, Inks, Plastics, Rubber And Plastic Foamed Organic Sol, Adhesives, Vinyl And Conveyor Belts. 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.
By using the quantum size effect and surface effect of the super fine grain itself, the interface of polypropylene can be enhanced to improve the compatibility, to reduce the dosage and improve the flame retardant efficiency. The thinner the flame retardant particles, the smaller the amount of smoke and the less smoke, the more obvious the flame retardant effect. So superrefining is the main development direction of inorganic flame retardant.
Yao Jialiang nano - Mg (OH) 2 was studied with micro - Mg (OH) 2 filled polypropylene system of flow and mechanical properties, flame retardant, flame retardant nanometer system with regard to the same quality score filling system, the performance is better than the microns to V when the filling amount was 60% ~ 0 level standard, and less smoke, flow and mechanical performance is better than that of micron filling system.
Different decomposition temperature of flame retardant in order to produce flame retardant synergistic effect, mixing flame retardants in a wide range of temperatures constantly release water vapor, which results in lower polypropylene in burning before and after oxygen concentration environment, flame retardant effect is superior to the single flame retardants [4]. Qu minjie studied Al(OH) 3, Mg(OH)2 and its synergistic effect on the performance of polypropylene flame retardancy and mechanical properties. When the ratio was appropriate, the effect of synergistic effect was significant. Compound flame retardant system can reduce single flame retardant dosage.
Such as the good flame retardant effect of inorganic flame retardant, non-toxic and smokeless and the combination of organic flame retardant can effectively reduce the amount of toxic halogen and bromine, and give full play to the synergistic flame retardant effect. With Mg (OH) 2? Al (OH) 3? P is polypropylene composite flame retardant, polypropylene? Mg (OH) 2? Al (OH) 3? P = 100? 50? 50? At 5, flame retardant performance and mechanical properties meet the requirements.
The combination of bromine flame retardants in inorganic flame retardants is beneficial to improve the comprehensive performance of polypropylene. The oxygen index reached 27% when the flame retarded copolymerization polypropylene (polypropylene R) was mixed with 15 0.6-3m Mg(OH)2 and 10 brominated diphenyl ether. A certain amount of Mg(OH)2 has a toughening effect on polypropylene R.
Compared with pentaerythritol (PER), urea polyphosphate and zinc borate, the highest flame retardant effect was achieved in the addition of melamine phosphate to Mg(OH)2 polypropylene R system.
