Polyvinyl alcohol containing phosphor flame retardant
With the increase of number of washing, polyvinyl alcohol base phosphorus flame retardant retention rate and the LOI is reduced, the LOI is 30.4%, before washing and after 1 and 5 times of washing, the LOI reduced to 27.8% and 26.8%, respectively, after washing 10 times of polyvinyl alcohol base phosphorus flame retardant adhesive content still reached 22.7%, and the flame retardant retention rate is as high as 76.2%, and the LOI was 26.2%, the flame retardant fabric has good washing fastness. The reason is that pva-poh is fixed to the fiber by means of physical adsorption and osmosis.
With the increase of catalyst, the yield has also improved, and phosphorus content showed that urea can not only improve production rate, catalyst can also inhibit dehydrated carbonized, avoid the product color deepened. However, the addition of catalyst will increase the moisture absorption rate of the product, and the yield and phosphorus content of the catalyst will be slower than that of 1%. So 1% is the best catalyst.
The absorption peak of the oscillating characteristics of the -oh telescopic is 33,36-3600cm-1, and the vibration of the vibration of the -oh plane is 1399cm-1. 2925cm-1 and 2847cm-1 have CH2 retractable vibration absorption peaks, and 1461cm-1 is the bending vibration of the CH2 surface. The PO telescopic vibration occurred in 1120cm-1; 1040cm-1 is C - O - P telescopic vibration. In addition, 918cm-1 is the characteristic absorption peak of P(V) - O, indicating that the esterification reaction has occurred.
(1. 3~1.4) x 10-6 (muti, J=44.8 Hz, 2H, CH2) and (3.8~3.9) x 10-6 (d, J=24.4 Hz, 1H, CH), respectively, respectively - CH2 - and CH - peak, while the chemical displacement of OH in pva-poh is 4.1 x 10-6 (s, 1.3 H, -oh). The esterification rate of the phosphoric acid was calculated from the peak area of the hydroxyl group and the peak area of CH. [(1.29-1.00) /1.00] * 100%= 29.0%, thereby inferring that m: n= 2.45:1
CH2 -- CH2 -- CH2 -- CH2 -- CHOH and -- CH2 -- CHOPO3H2 -- CH2 -- CH2 -- the displacement value.
The displacement value is -0.012 x 10-6, single peak, indicating that the phosphorus element only exists in C - O - PO3H2.
Trimethyl phosphate (TMP)

Export rights: the right to import and export company.
Trimethyl phosphate (TMP) use is mainly used in medicine, pesticides, solvents and extractants, used as a solvent, extraction, determination of zirconium and GC stationary liquid, the ester is used in medicine and pesticide solvent and extractant. Pesticide intermediates. In Japan, Trimethyl phosphate use as anti stain of textile oil and polymer, flame retardant additive for lithium ion battery.
Trimethyl phosphate is currently the main market in India, mostly for textile auxiliaries, the products are mainly exported to Japan, South Korea, Thailand, India.

Elements of atomic number ratio of n (C) : n (H) : n (O) n (P) = 8.0, 14.5, 14.5, 1.0, and by nuclear magnetic resonance (NMR) concluded that n (C) : n (H) n (O) : n (P) = 7:15:6:1. Once again proved that synthesis of PVA - POH structure is correct.
PVA - POH initial decomposition temperature is 110 ℃ (Ton), and there are two significant thermal cracking stage, the first stage of weightlessness in 116 ~ 200 ℃, the maximum decomposition temperature is 170 ℃, 19.1% weight loss, the second phase in 402 ~ 470 ℃, the maximum decomposition temperature is 440 ℃, weightlessness 8. 6%, at 590 ℃, residual mass fraction of 53.35%. Illustrate that flame retardant PVA - POH decomposition, more easily under 200 ℃ and 400 ℃ or more significantly higher thermal stability. The initial decomposition temperature and wave number/cm-1 of polyvinyl phosphate flame retardant.
There are three obvious endothermic peaks in the process of the first pyrolysis weightloss process, indicating that the thermal decomposition process is not a primitive reaction, but a multi-step reaction. In the second heat process, 416 ~ 447 ℃ appeared an obvious exothermic peak, it may be generated polyphosphoric acid phosphate dehydration process.
Pva-poh was synthesized with PVA and phosphoric acid, and the best synthesis condition was: m(H3PO4)/m(PVA)= 2. 0100 ℃ reaction 120 min 1% catalyst. The structure of pva-poh was characterized by ft-ir, NMR and element analysis, and the thermal performance was analyzed by TGA- DSC. The results showed that pva-poh had excellent flame retardant performance and the LOI was still 26.2% after 10 times of washing.
Fireguardfcx-210, a new phosphorous flame retardant for many kinds of resins. It can be used in ABS (acrylonitrile-butadiene-styrene copolymer resin), polystyrene resin, polyamide resin and various kinds of resin used in electronic products and automobiles.
