The co-effect of flame retardants is used
Let us know with some flame retardant association effect, which is composed of two or more components of flame retardant system, should choose only proper, the sum of the flame retardant effect will be better than that of the flame retardant effect of components.
In flame retardant technology, more and more manufacturers choose synergistic flame retardant, because of the synergistic flame retardant is not merely to improve the flame retardant efficiency of polymer, and can reduce the content of some components in the flame retardant system under the premise of meet the requirements of flame retardant and can be a very good cost control.
At present, the most common use of flame retardant association effect is the phosphorus-containing compounds and antimony trioxide of flame retardant system, but in some flame retardant materials, antimony trioxide can be composed of ferric oxide, zinc oxide, zinc borate and other to replace, they in chlorine flame retardant polyamide and special effect in the epoxy resin, this kind of association effect agent can not only capture free radicals in gas phase, and also can play a role in the condensed phase, the flame retardant material surface to form carbon layer.
According to past experience, the association effect of flame retardants in for aliphatic chlorine flame retarding agent, is the most effective coordinated effect agent ferric oxide, which is in some plastic association effect even better than antimony trioxide. With zinc oxide as some halogen flame retardant, the CTI (leakage track index) of flame retardant base can be given. Will stannate zinc, zinc molybdate and zinc silicate and zinc borate compounds used as the association effect of phosphorus-containing flame retardant agent, will improve some plastic UL94 level of flame retardant and CTI value two aspects, are better than that of antimony trioxide.
By using zinc trioxide and zinc borate, it can slow down the smoldering of flame retardant materials and improve the color of flame retardant materials.
Flame-retardant polystyrene, ABS and some other halogen flame retardants in plastic can be used as a synergetic agent using antimony - inorganic silicate complex, not only low cost, but also low tone intensity. In addition, antimony compounds and magnesium compound compounds can improve the flame retardant effect as well as the smoke suppression.
Trixylyl Phosphate(TXP) Use
Phosphate Trisphenylene Phosphate Is Low, Resistant To Hydrolysis, Good Flame Retardant Can Be Used As Vinyl Resin, Cellulose Resin, Natural And Synthetic Rubber Plasticizer, Low Volatility, Good Water Resistance, Flame Retardant. Trichenylene Phosphate Use For Use In Combustible Turbine Oils, With Good Flame Resistance And Good Thermal Oxidation Safety, Good Lubricity, Extreme Pressure Antiwear Additives For Lubricants, Thickeners. Also Used For Fire-Resistant Turbine Oil, With Good Thermal Oxidation Stability, Lubricity, As A Lubricant Anti-Wear Additives, Plasticizers, But Also For Flame Retardant, Wear-Resistant, Resistant To The Mold Of The Cable, Ethylene Conveyor Belt, Artificial Leather, Foam, Flooring Materials, But Also In Metallurgy, Electricity, Mechanical Engineering And Other Aspects As A Fire-Resistant Hydraulic Oil.
Zinc stearate/talc/iron compound is a kind of low smoke agent association effect, adding suitable amount of this association effect, can make some initial 4 min containing halogen flame retardant plastic smoke density decreased from 300 to 300, light transmittance increased from 0.01% to 0.1%.
Some plastic HIPS and ABS, bromine flame retardants and there are synergies between chlorine flame retardants, for example, using aliphatic chloride series flame retardant with a mixture of ten pbdes to flame retardant ABS, the ratio of 1:1, ABS oxygen index reached more than 40.
Because many kinds of phosphorus compounds have flame retardant effects, the researchers have done a lot of research on the actual application and mechanism of phosphorus compounds as flame retardants. Many patents say that phosphorus and bromine have synergies, but careful studies have shown that the use of phosphorus compounds with bromine compounds does have good effects, but not necessarily synergies.
Some reports indicate that as reactive flame retardant organic phosphorus diglycol or ternary alcohol and brominated flame retardants can be used to get a significant effect. In the case of the whole reaction type flame retardant using low growth rate. The reaction type flame retardant of the phosphorus-bromide system has its obvious advantages when used in the printed circuit board of epoxy resin: it has good dimensional stability. Good heat resistance. It can also drastically reduce the amount of bromine.
For example. It turns out that 52 doses of tetrabromobisphenol A, which can be reduced to 28 copies, can be reduced to the requirements of UL - 94V - 0 due to the addition of 35 phosphorous diglycol or diglycol. Under the welding temperature (300 ℃) of thermal stability can be increased to 5.0 from 2.5 min min.
Synergistic effect is a physical and chemical phenomena, also called synergy, refers to two or more components together or mixing together, the effects of greater than the sum of various components of separate application effect. And the substance that produces this effect on the mixture is called synergist. The synergistic effect is often used to guide the composition of chemical products in order to obtain the final product performance enhancement.
