Expansive compound flame retardant
Using ammonium polyphosphate (APP) and the expansion of the melamine (MEL) composite flame retardant for fabric finishing, vertical burning test, thermogravimetric analysis, scanning electron microscope (sem) analysis, the results showed that when the mix of APP and MEL is 2:1, inflating composite flame retardant was 25%, the dosage of fabric carbon loss as low as 10.0 cm in length, limit oxygen index as high as 37%. Flame retardant finishing after 700 ℃ when the fabric quality retention by composite flame retardant without inflating at 16% to 35%, the expansion of the fabric during combustion can form foam coking coal layer, a good expansion flame retardant effect. In addition, the strength, whiteness, permeability and feel of the fabric have declined to a certain extent.
Expansive flame retardant is generally composed of sour-source, gas source and carbon source. Acid source can be inorganic acid or the heat generated inorganic acid compounds, such as phosphoric acid, sulfuric acid, phosphate and borate, such as: air foam is also called the source, commonly used melamine and dicyandiamide, such as: carbon source is to form the basis for bubble carbonization layer, mainly is some high carbon content of polyol, such as pentaerythritol and its dimer and trimer.
The expansion type flame retardant is mainly formed by forming porous foam carbon layer. The formation process of carbon layer is as follows: at lower temperature, the acid source decomposition releases the esterification polyols and the inorganic acid as dehydrating agent. With the increase of temperature, inorganic acids and polyols for esterification reaction and make the system to melt, water vapor in the process of reaction and the non-combustible gases produced by the air supply has been expansion foam in the molten state of the system and at the same time, the multivariate alcohol and ester dehydration into carbon, inorganic matter and carbon residue, and foaming system further inflation.
When the reaction is close to completion, the system coking and solidifying, forming a porous foam carbon layer, this layer is insulated, the oxygen is isolated, the combustion chain is cut off, and it has the flame retardant effect. In addition, the composition of expansion type flame retardant system of P - N - C in the heat produce nitric oxide (NO), nitrogen (N2) and ammonia (NH3), and other non-combustible gases, these gases capture active free radicals, burning depends on such as H, and OH, and led to the suspension of combustion reaction chain, so the expansion type flame retardant has excellent flame retardant properties.
Isopropylphenyl Phosphate(IPPP95)
Cas Number: 68937-41-7
Customs Code HS: 29199000
Refund: Isopropylphenyl Phosphate, Flame Retardant IPPP95 Tax Rebate Of 9%.
Net Weight 200KG / Galvanized Iron Drum (A Small Cabinet To Play With 16 Tons), 1000KG / IB Barrel (A Small Cabinet 18 Tons) Or 23 Tons ISOTANK.
Isopropylphenyl Phosphate(IPPP95) Use:
Isopropylphenyl Phosphate, Flame Retardant IPPP95 Is Used For Rubber Products And PVC Plastic Flame Retardant Conveyor Belt, Cable, Chloroprene Rubber, Nitrile Rubber And Other Synthetic Rubber Flame Retardant Plasticizer, Triisopropyl Phenyl Phosphate Applicable To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin And Other Fields.
Isopropylphenyl Phosphate, Flame Retardant IPPP95 Halogen-Free Phosphate Flame Retardant Plasticizer, Will Not Twice Pollute The Environment; In The Phosphate Ester Species Is A Viscosity, Phosphorus Content Is More Moderate A Model. This Product Is Colorless And Transparent, Good Compatibility, The Use Of Both Flame Retardant And Plasticizer, In The Flame Retardant And Plasticizer To Play A Balance Between The Role, But Also To Make The Processing Of The Same Material And Its Physical Properties.
The expansion type flame retardant has been used in the flame retardant finishing of plastics, rubber and synthetic polymers [4, 5], and the flame retardant of textile materials is rarely reported. Flax fibers are cellulose fibers, polyhydroxy polymers, which are carbon sources themselves. In order to reduce costs, this experiment adopts the ammonium polyphosphate (acid) and melamine compound with steam source), to finishing of fabric (carbon source), respectively, with oxygen index tester, vertical combustion apparatus and thermogravimetric analyzer determination of flame retardant properties of the treated fabrics.
The white degree of the finished fabric was reduced from 92.5% to 90.6%, with the quality fraction of 25% as the expansion type flame retardant. The flame retardant finishing had little effect on the whiteness of the fabric.
After the flame retardant finishing, the fabric strength slightly decreased. The breathable volume of fabric is reduced from 236.2 L/m2 ?s to 180.4 L/m2 ? s. This is because the fabric after finishing, expansion type flame retardant fixation not only on the surface of the fabric, but also permeate to the fiber, on the one hand, limit the relative slip between the flax fiber, fiber in the external force, the stress concentration, make it easier for macromolecular chain rupture, resulting in the decrease in the strength of fiber, on the other hand cut holes and gaps in the fabric or smaller, so that the fabric permeability is decreased.
The feel of the fabric is reduced from 5 to 3, indicating that the expansion of the flame retardant can make the fabric feel hard. In order to improve the feel of the fabric after finishing, it can be added in the finishing solution to a good softener.
When unburned, the expansive flame retardant is distributed evenly between the surface or fiber of the fabric. After burning, the fabric produced a noticeable expansion foaming effect, forming a loose coking carbon layer.
An expansive compound flame retardant composed of APP and MEL has a good effect on the fabric. When the ratio of APP to MEL is 2:1, the total mass fraction is 25%, the LOI value of the expanded flame retardant is 37%, the length of carbon loss is 10.0 cm, and the flame retardant performance is good.
