Application range of flame retardant

Application range of flame retardant

This paper introduces the application scope of flame retardant, and hopes to help you.

Flame retardant application range (1) flame retardant elevator seal

This kind of rubber, antimony trioxide in the EPPM, ten pbdes, aluminum hydroxide flame retardants and, flame retardant effect is good, the flame retardant oxygen index (LOI) 38% ~ 46%, used in the manufacture of high flame retardant elevator sealing strip.

Application range of flame retardant (2) flame retardant cable sheath

With zinc borate October, 190 ~ 320, 2 kinds of flame retardants and aluminum hydroxide filler hydrogenated butyl eyes rubber or EVM entry polymers, flame retardant performance can be obtained very high rubber, suitable for manufacturing cable sheath. The hydrogenated butyronitrile rubber is used to add 320 parts of aluminum hydroxide and the flame retardant oxygen index (LOI) can reach 77%, and the adhesive can maintain good mechanical properties.

Application scope of flame retardant (3) flame retardant conveyor belt

The flame retardant conveyor belt and the triangle belt can be made by adding phosphate amide or polyphosphate to natural rubber.

Application range of flame retardant (4) flame retardant high voltage appliance

The silicone rubber 2 propylene rubber is filled with aluminum hydroxide flame retardant, and the high pressure cap and wedge on the color picture tube can be made.

Flame retardant cable (5) the application scope of flame retardant nuclear power plants with silane or unsaturated acid modified aluminum hydroxide 200, filled epdm, can obtain excellent flame retardant properties of rubber, oxygen index (LOI) of 33%, low smoke and non-toxic, can make nuclear power cable.

Flame retardants (6) the application scope of flame retardant EPDM 33 cyclic aliphatic compounds or 105 aluminum hydroxide chloride magnesium hydroxide filling to 100 or 105 in EPDM, can obtain good flame retardant rubber, oxygen index (LOI) is about 27%.

The application range of flame retardant (7) flame retardant silicone rubber with 012 52-phenyltetrazole, 1 bicarbonate of magnesium carbonate or 1 bicarbonate of sodium bicarbonate added to silicone rubber, can be made flame retardant silicone rubber.

The application range of flame retardant (8) flame retardant natural rubber application red phosphorus, chlorinated compound and ammonium bromide 3 flame retardant combination are added to natural rubber, which can obtain good flame retardant properties.



Trimethyl phosphate (TMP)

Trimethyl phosphate TMP raw material is three phosphorus oxychloride with methanol in the presence of potassium carbonate reaction of Trimethyl phosphate. At the same time, the reaction of two with methyl phosphoric acid potassium salt, sulfuric acid two methyl ester reaction of Trimethyl phosphate. Trimethyl phosphate crude product after washing, bleaching, dehydration, vacuum distillation was finished. The consumption of raw material: three phosphorus oxychloride 1094kg/t, methanol 686kg/t.

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.

The application range of the flame retardants (9), phosphate flame retardant styrene butadiene rubber using bromine, aromatic bromide, antimony trioxide, and four kinds of flame retardants and ammonium chloride, join the styrene-butadiene rubber, can get high rubber flame retardant effect.

The application range of the flame retardants (10) of unsaturated rubber flame retardant rubber with 5 ~ 10 copies of two alkyl phenyl phosphate ester, 10 ~ 15 copies of antimony trioxide and 3 ~ 10 copies of iodine composite flame retardant, added to the NR, SBR, BR, NBR, can get rubber flame retardant effect is good.

The research and development of silicone flame retardant and its flame retardant technology have opened a new chapter in the development of flame retardant technology. Although the price of silicone flame retardants is high, the development potential and application prospect of the flame retardant is huge and broad. According to different application fields, science of silicone compounds the molecular design and synthesis of flame retardant association of the optimum combination system, and the flame retardant mechanism of thorough research, people are subject to further exploration and efforts.

In general, a certain amount of phosphorus is added to the flame retardant of bromine, which can not only improve the flame retardant effect, but also reduce the dosage of flame retardants and reduce the impact on the environment. South China university of technology has studied the synergistic effect of silicone resin SFR100 and TBAB on ABS, which can effectively improve the flame retardant performance and impact strength of ABS, and improve its electrical performance.

In a word, for flame retardant compound with is to select the most appropriate after fully considering the thermodynamics properties of polymer varieties of flame retardant, maximize flame retardant association effect, at the same time consideration and all kinds of additives such as plasticizer, heat stabilizer, dispersing agent, coupling agent, toughening agent, interactions between the to achieve the purpose of reducing consumption, improve the effect of flame retardant.

Expansive flame retardant (IFR) is a kind of flame retardant with C, N and P core components. The IFR is mainly composed of three parts: (1) carbon source (carbonaceous) : generally carbon rich and multi-functional group, such as starch, pentaerythritol and diacyl alcohol; (2) acid source (dehydrating agent) : generally inorganic acid or salt, such as phosphoric acid and ammonium polyphosphate, can be formed in situ during heating. (3) air source (foaming agent) : generally polycarbon containing nitrogen, such as urea, melamine, dicyandiamide and derivatives.
