Classification of commonly used flame retardants
There are many kinds of flame retardants, and there are many ways to classify flame retardants. According to the classification of flame retardant elements, it is divided into halogen flame retardant, phosphorous flame retardant and nitrogen flame retardant.
The classification of commonly used flame retardants is classified according to the method of use and the existence of polymer. The classification of commonly used flame retardants is divided into three kinds of non-durable flame retardant finishing agent, semi-durable flame retardant finishing agent and durability retardant finishing agent according to the durability of flame retardant fabric. The classification of commonly used flame retardants can be classified as inorganic flame retardant and organic flame retardant. The following is mainly introduced in the following two methods classification of flame retardants.
To be classified according to the durability of the fabric
(1) non-durable flame retardant finishing agent: also known as temporary flame retardant finishing agent, mostly water soluble (or emulsion) inorganic salt. The flame retardants are dissolved in water and the fabric is soaked and dried to be used. In the second bath, the second bath is made of ammonia or soda, and the oxide is deposited on the fabric. This method is simple and inexpensive, but the fabric has poor handle, and the flame retardant effect is greatly reduced after washing. Use a disposable protective suit.
(2) semi-durable flame retardant finishing agent: the flame retardant textiles treated with this process can be used for 1 ~ 10 mild washing, but not high temperature soap. The method is a mixture of urea phosphoric acid (commonly known as Banflam), phosphoric acid urinary ester method, ammonium phosphite and ammonium cyanate.
(3) durability retardant finishing agent: chemical method is used to polymerize or shrink the internal surface of the fiber to form a polymer that is insoluble in water, and generally requires more than 30 washes. The method mainly includes the steam bus (CP) method and the Proban method. The CP method is created by the Swiss automobile company. The process is easy to implement and the flame retardant effect is remarkable. The disadvantage is that the fabric has a great loss of strength and has a great influence on apparel performance.
Proban method of finishing of fabric, flame retardant effect is good, especially after processing the fabric handle and strong keep is incomparable by any other sorting method, but this law risk bigger, serious environmental pollution, thus promotion is limited.

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.
Classification by type of compound of flame retardant
Inorganic flame retardants: (1) the main effect of inorganic flame retardant is endothermic, the main varieties are aluminum hydroxide, magnesium hydroxide, red phosphorus, antimony oxide, molybdenum oxide, ammonium molybdate, zinc borate, zinc oxide, zirconium oxide, zirconium hydroxide, etc, among them with aluminium hydroxide, magnesium hydroxide, red phosphorus, antimony oxide is most widely applied, especially not only can aluminum hydroxide, magnesium hydroxide flame retardant effect, and can be filled.
They have the characteristics of good thermal stability, high efficiency, anti-smoking, blocking drop, filling safety, basic pollution-free environment and low price, and are widely used in halogen free flame retardant materials. However, inorganic flame retardants have poor washing resistance because inorganic flame retardants have strong polarity and hydrophilic properties and poor compatibility with non-polar fabrics. In order to meet the requirements of flame retardant, the addition of inorganic flame retardants is larger, which has great influence on mechanical properties and processing performance of the materials.
Therefore, the ultrafine and nano-chemical research on the traditional inorganic flame retardants has attracted unprecedented attention in recent years. In addition, in order to reduce the flame retardant dosage of the same flame retardant, the compound of flame retardant is studied, and the synergistic effect of flame retardant is studied, and the research direction of flame retardant is also studied in recent years.
(2) organic flame retardants: organic flame retardants are divided into two series: phosphorus and halide series. The former is mostly liquid at room temperature and has a large amount of smoke and toxicity. It is required that the flame retardant structure contains a lot of H and O elements to dehydrate and form carbonized layer, so its application is very limited. Halogen flame retardants mainly include chlorine and bromine. But the effect of chlorinated flame retardants is much worse than that of bromine flame retardants, which is due to the difficulty of producing free chlorine.
