Polyester durable flame retardant
The TFP of polyester durable flame retardant is synthesized by two-step method, and it is used for the flame retardant finishing of polyester fabric.
The results showed that the pH value of working fluid was 6 when the dosage of flame retardants was 120g/L. At the time of 5, the fabric has a good flame retardant effect (to reach the national standard B1 level) and excellent washable performance (which can be washed for more than 50 times) without affecting the color and feel of the fabric.
The flame retardant of the fabric refers to that the textile can automatically stop the burning when it encounters the ignition source, and automatically extinguish the flame after leaving the flame. With the continuous development of the fiber industry, pure polyester fabrics are widely used in various fields. Therefore, the demand for polyester durable flame retardants is higher and higher.
Many countries have strict regulations on the combustible performance indicators of many kinds of textiles, such as interior decoration products, aviation, navigation and movie theaters. Therefore, the demand for polyester durable flame retardants is also increasing.
Synthetic experiment of polyester durable flame retardant. Fabric: 100% pure polyester. Drugs: sodium hydroxide, sodium bicarbonate, TMP, triethyl phosphite and dimethyl phosphonate are all analyzed. Instruments: pa-2t machine; Electronic balance; YG (B) 815D-1 fabric flame retardant tester; AATCC-135 type washing machine and dryer; Datacolor colorimeter.
Flame retardants (1) the synthesis intermediates 2-ring phosphite ester synthesis: the trimethylolpropane (TMP) in 2 l four bottles of melting temperature (TMP melting point for 54 ℃), after being completely melt start stirring, join, diethyl phosphite, adding catalyst (Cat1) at the same time, heating to the reaction temperature, reaction after 2 h, vacuum distillation by-products of ethanol. (2) product annular phosphonic acid ester synthesis: the catalyst (Cat2, Cat3) and dimethyl methyl phosphonic acid added to four bottles, heating reflux reaction 8 ￣ 10 h, vacuum distillation excess dimethyl methyl phosphonic acid and by-products, temperature and cooling can be light yellow viscous liquid.
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.
Flame retardant finishing process More than two dip two rolling (rolling rate 80%) and preliminary drying (120 ℃, 120 s) - > curing (190 ℃, 60 s) - washing and drying - return to testing, evaluation.
Test flame retardation: according to GB/t545-1997 vertical combustion method.
When the cloth sample is burning vertically, the damage length, the duration of afterburning, the shorter the time of smoldering, the better the flame retardant performance; Washing resistance: according to aatcc-135; Color change: the original fabric is used for the sample, and the sample is determined by the sample of the sample of delta L *, delta a *, delta b * and delta E *. Delta L * is the difference; Delta a * is the red and green light, the more positive, the more red; Delta b * is the yellow and blue light difference, the more positive, the more yellow light; Delta E * is the total color difference, and the larger the value, the greater the color difference between the original and the original cloth.
Flame retardant agent to finish fabric has a great influence on flame retardant effect, along with the increase of dosage of flame retardant, flame retardant effect of the treated fabrics, the better, when the dosage increases to a certain value, flame retardant effect improvement is not obvious, but for fabric handle, color has a significant impact.
The white fabric has a certain degree of yellow change after the flame retardant finishing, and with the increase of the amount of flame retardant, the more obvious the yellow change, directly affect the applicability of the fabric. When the dosage is 120g/L, its comprehensive application performance is optimal.
After flame retardant finishing, the fabric can cause color change, and the degree of color change is closely related to the amount of flame retardant. With the increase of flame retardant dosage, the fabric color becomes more and more obvious. In order to make the fabric have good flame retardant performance, the color change is small, and the dosage is 120g/L.
