Inorganic flame retardant of polyethylene (PE)
Antimony oxide is one of inorganic flame retardants of polyethylene (PE). When used alone, antimony oxide has little flame retardancy, but it can improve the efficiency of halogenated flame retardants when used in combination with halogenated flame retardants. Therefore, it is an indispensable synergist for almost all halogenated flame retardants.
Although in recent years, non halogen flame retardant high voice, but because I could not find the ideal substitute of halogenated flame retardant flame retardant will still occupy the leading position in the field of quite a long time, so the antimony oxide is still some room for development, at present the modification and package processing, the United States, Britain, Switzerland, etc. China has developed antimony oxide flame retardant masterbatch, widely used in plastics, synthetic fibers, textiles and other fields.
However, due to the toxicity of antimony oxide, foreign alternative research has been carried out, currently can partially replace three antimony oxide two flame retardant zinc borate, zinc sulfide, zinc stannate, zirconium compounds and molybdenum compounds. Some inorganic compounds containing tin have been developed abroad, which have good synergistic effect on bromine and chlorine flame retardants, and their flame retardant efficiency is equivalent to that of antimony oxide, which can completely replace the application of antimony oxide in various fields, and the toxicity is very low.
Five antimony oxide two is an inorganic flame retardant of polyethylene (PE), and has excellent flame retardant properties. Because of its strong permeability, strong adhesion and long lasting flame retardance. Five oxidation of two antimony is mainly prepared by oxidation method, chlorination hydrolysis method, etc..
Inorganic phosphorus compounds inorganic phosphorus flame retardants include red phosphorus, phosphate and ammonium polyphosphate. Red phosphorus flame retardant is a kind of excellent performance, high efficiency, low toxicity and smoke suppression of fire retardant effect, but in the actual application of easy moisture absorption and oxidation, and emit toxic gases, dust explosive, and a deep red color, so the use is very limited. In order to solve the above problems, the surface treatment of red phosphorus is red phosphorus as the main direction of flame retardant. The microencapsulation technique is the most effective surface treatment.
China has done a lot of work to study the general use of encapsulated red phosphorus, aluminum hydroxide, metal sulfate, synthetic resin as wall material package, but the domestic market has not been widely applied in the future, to speed up efforts to research and promotion of the product, in addition to the research and application of material compatibility problems and to work hard.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
CAS No.:13674-87-8
HS: 29199000
Tax Rate (%): 9%
Tris (1,3-Dichloro-2-Propyl) Phosphate (TDCPP) Raw Materials: Phosphorus Oxychloride, Epichlorohydrin
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
Ammonium phosphate and ammonium polyphosphate and their corresponding intumescent flame retardants have become an active research field of inorganic flame retardants. With a long chain of ammonium polyphosphate (APP) based P2N flame retardant element content of the product is high, good thermal stability, the product almost neutral, can cooperate with other substances, flame retardant properties and lasting, it develops very rapidly in recent years, many countries have introduced a number of excellent performance APP.
Borate series products is a kind of polyethylene (PE) inorganic flame retardant, ammonium borate, boric acid with five ammonium, sodium metaborate, ammonium fluoroborate, barium borate, zinc borate. At present, the main use of zinc borate products, zinc borate the earliest product called FrieBrakeZB, therefore referred to as FB flame retardant, zinc borate can significantly improve the product's fire resistance.
Due to the relatively high price of borate flame retardants, the application of FB borate flame retardants is in the development stage, because the FB borate flame retardant has good performance, safety, non-toxic, low price, raw material source is easy to obtain.
Mainly used in high-rise buildings, elevator accessories, rubber products, plastic wire, cable sheath, temporary buildings, military products, plastics, TV shell and parts, ship paint and synthetic fiber products, but also has irreplaceable superiority in some areas, so the development prospect is widely optimistic, also rich in boron resources in China and domestic resources in the region, can accelerate the synthesis and development of borate fire retardant.
Fire smoke is molybdenum compound first and most easily fatal factors, contemporary flame retardant technology "flame retardant and smoke suppression". For some polymers, "smoke" is more important than the "flame", so the development of flame retardant and smoke suppression is very important, so far, people found that suppression the best is the smoke agent, molybdenum compounds, so the development and application of molybdenum compounds has become a hot research topic in the field of flame retardant.
The development of molybdate containing ammonium retardunt, capable of processing temperatures above 200 degrees, experts believe that the molybdenum zinc system will enable PVC to compete with the fluorinated polymer used in wire and cable fire retardant coating layer, especially for low smoke; other molybdenum compounds can be used with other flame retardants. At present, molybdenum compounds as flame retardants are still in their infancy in china.
