2017-9-30 11:50:10
Phosphorous nitrogen flame retardant have a significant role in the flame retardant of natural fiber fabrics, so it is necessary to make them as a class of flame retardants.
Nitrogen phosphorus flame retardants used in flame retardant finishing of cotton fiber, phosphorus can promote cotton fiber dehydration into carbon, and nitrogen element to improve the efficiency of phosphorus flame retardant performance has a collaborative, so a lot of phosphorus and nitrogen flame retardant used for the flame retardant cotton fiber has good effect. Phospho-nitrogen flame retardants mainly include nitrogen phosphate (esters) and recent high - attention phospho-phosphatic flame retardants.
Nitrogen phosphorus flame retardant with high content of phosphorus and nitrogen and excellent flame retardant performance, at present, there are a wide variety of containing hydroxyl, amino, halogen and carbonyl carbon and other functional groups of phosphorus with flame retardant was synthesized and used in the study of various materials of flame retardant, but as a result of phosphorus chemical flame retardant synthetic process are usually more complex, so most was still in the stage of research.
In flame retardant cellulose fabric, there are many related researches, and have a good effect. Such as six hydroxyl amino ring three phosphorus mixed three nitrogen (HHMAPT), it is composed of six amino ring three phosphorus mixed three nitrogen (HACTP) and formaldehyde reaction system, with the pad of cotton fabric, drying, curing process, again for fabric washing, flame retardant properties of treated fabrics had improved, but also to the influence of the physical and mechanical properties is very small.
There are many phospho-nitrogen flame retardants in cellulosic fabrics that contain nitrogen phosphate (ester), for example, the flame retardant Pyrovatex CP is widely used in cellulose fabrics such as cotton and hemp, and its molecular formula is (ch3o2poch2conhch2oh). Use it to make the fabric flame retardant, washable, the feeling is very good, wear comfortable, the influence of color degree also is not big. There is also a large amount of concentrated acid source, carbon source or concentrated source, carbon source and gas derived from puffed flame retardant, which are mostly nitrogen containing phosphorus compounds. Three phosphates (ester) compounds have been proved to be excellent flame retardants .
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)

1,3-Dichloro-2-Propanolphosphate (3: 1); 1,3-Dichloro-2-Propanolophosphate (3: 1) 2-Propanol, 1,3-Dichloro, Phosphate (3: 1); 2-Propanol, 1,3-Dichloro-, Phosphate (3: 1) ); Crp (Fireproofingagent); Emulsion 212
CAS No.:13674-87-8
EINECS Number: 237-159-2
Molecular Formula: C9H15Cl6O4P
Molecular Weight: 430.9
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
The synergistic flame retardation effect between phosphorus and other elements has been reported in many literatures, including the most studies of nitrogen and phosphorous and flame retardant effects. The study on the mechanism of phosphorus-nitrogen synergistic effect is not perfect, and the literature report analyzes the possibility that nitrogen can raise the flame retardant efficiency from three aspects.
(1) in the combustion process, nitrogen and phosphorus form the phosphate structure, which is more likely to be esterified with cellulose, which is good in thermal stability
(2) the presence of nitrogen atoms is beneficial to the decomposition and formation of phosphoric acid, which plays a strong catalytic dehydrating effect
(3) the combination of nitrogenous compounds and phosphoric acid has the effect of swelling in the flame, which can cause the fiber to expand and form coke. Not all nitrogenous compounds have synergistic effects with phosphorus. Different nitrogen compounds have different synergistic abilities, and some nitrogen compounds have a phase elimination effect. In addition, there are many studies on the synergistic effects of phosphorus elements and other elements, such as halogens and boron elements.
In under the situation of halogen flame retardants influence decrease gradually, phosphorus flame retardant because of its low toxicity, durable, good thermal stability etc widely followed, in the field of flame retardant fiber fabric research occupies more and more heavy weight. But we also should see, so far, all the phosphorus flame retardants have respective shortcomings, such as not washable, high cost and other performance fabric, etc., all of these need to be solved through our efforts.
Oxidation of phosphorus flame retardants are used in natural fiber, three (nitrogen heterocyclic propenyl) phosphine oxide (APO) is a kind of used for cotton fabric flame retardant, it not only give flame retardancy to cotton fabric, cotton fabric and get free iron performance, but the safety and health of nitrogen heterocyclic allyl problems restrict the industrial application of APO. And some of the phenyl phosphine oxide containing two reactive groups, such as diphenyl - 2, 5 - two (hydroxyl ethoxy) phenyl phosphine oxide and methyl 2 (3, 5 - two br - 4 - hydroxy ethoxy) phenyl phosphine oxide, etc are used for flame retardant polyester fibers.
