Fire retardant compound technology
In modern flame retardant technology, flame retardant compound is an extremely important aspect. The compound technology of flame retardant contains two aspects: one is the complex problem between different flame retardant agents; The second is the cooperation between flame retardant and different substrate and different plastic additives.
It has been proved that some flame retardants are only suitable for certain matrix resins. Therefore, different matrix resin should be selected for the appropriate flame retardant elements. Compound flame retardant system has the characteristics of multiple flame retardants, and the compound coordination of different flame retardants has opened up a wide prospect for the flame retardant of synthetic materials.
The flame retardant compound can be carried out between organic, inorganic and other organisms. Including organic and inorganic flame retardant compound is more widely used, such as silicon phosphorus flame retardants distribution system, this kind of distribution system and the efficient of organic flame retardants and inorganic flame retardant function of the low smoke, non-toxic, can effectively reduce the cost and reducing the amount of inorganic flame retardant, improve the function of the material.
The flame retardant system, which has one of the following characteristics, is likely to be a highly effective flame retardant with development prospect: (1) catalytic flame retardation; (2) inhibit the oxidation reaction of condensed phase; (3) high performance gas phase flame retardant; (4) to form an effective coke layer or coke layer containing other flame retardant elements such as silicon and phosphorus. Phosphorus-silicon synergistic flame retardant has the characteristics of (1), (2) and (4), and thus the phospho-silicon synergistic flame retardant is one of the important directions for future development of flame retardant technology.
Resin system of the LOI from the original 23.0% to 28.5%, that of the modified epoxy resin system improve the flame retardancy of the good, the epoxy resin of phosphorus element by "acid induced dehydrogenation reaction mechanism" to promote the formation of the resin carbon layer, in the region of the high temperature, epoxy resin form silica protective layer of silicon on the surface of specimen, inhibits the generated carbon layer thermal oxidation degradation reaction, prevent the quality of the coking coal loss.

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.
Also using sol-gel method, some scholars by bisphenol A diglycidyl ether epoxy resin (DGEBA) and four ethoxy silane (TEOS) was prepared by integrating phosphorus silicon nanometer composite epoxy resin, silicon phosphorus in hybrid materials of the crosslinking network to improve the flame retardant epoxy resin.
Combustion experiments show that: at 800 ℃, pure epoxy resin into charcoal at a rate of 14.8%, and the modified epoxy resin as the rate of 31%; The LOI of pure epoxy resin was 24% and the modified epoxy resin was 32 %. Worth mentioning is that the epoxy resin containing a P - C and P - O key, in the process of thermal degradation, belongs to the weaker crosslinking, easily affected by the shearing action of chain rupture, making modification of epoxy resin at low temperature and high temperature thermal stability performance is quite different, pure epoxy resin 10% weight loss temperature is 399 ℃, and the modified epoxy resin 10% weight loss temperature is 313 ℃, and carbon rate before 400 ℃ lower than the pure resin.
With the increase of temperature, the modified epoxy resin shows better and better thermal stability. Siloxane combustion residue generated in the process of burning white silica and carbon composite inorganic layer double barrier effect, cut off the combustible gas and fire the passage between the melting zone, protect the polymer from flame thermal radiation generated by the.
Hsiue and others using the in situ sol-gel method, the phosphorus silicon of organic-inorganic nano hybrid material of epoxy resin, the glass transition temperature of epoxy resin hybrid increased with the increase of silicon content, phosphorus silicon synergies between the flame retardant performance of epoxy resin is greatly improved, when the content of phosphorus and silicon were 4.35% and 15.63% respectively, the material of the LOI by before modification of 26.0% to 44.5% after processing.
Epoxy resin has many outstanding features, such as good thermal stability, insulation, adhesive, good mechanical properties, excellent molding process performance and good cost performance, etc., are widely used in electronic components of adhesive, encapsulation and printed circuit board (PWBs) production and other fields. The traditional flame retardant method of epoxy resin [8] is both by adding bromine and antimony oxides, which will have different negative effects on the environment.
