High efficiency flame retardant of epoxy resin
A lot of negative effects of epoxy resin flame retardant containing halogen on the social environment and our lives, the future of halogen containing flame retardant epoxy resin will be low smoke, low toxicity, no pollution, flame retardant epoxy resin is replaced, which is efficient flame retardant epoxy resin to the inevitable tendency of the development of flame retardant epoxy resin. The flame retardant agent will become the future development direction.
Flame retardant synergistic effect of antimony oxide flame retardant antimony oxide itself, the study found that the flame retardant effect is not very good, but with the halogen flame retardant and flame retardant synergism greatly, this is due to the burning of natural SbCl3 and SbBr3 antimony halide large proportion of polymer surface coverage effect, and capture free radicals the role in the gaseous state.
Synergistic effect of red phosphorus red phosphorus when used alone, the flame-retardant effect is not ideal, but when Al (OH) 3, Mg (OH) 2 with flame retardant, flame retardant has obvious synergistic effect, adding a small amount of red phosphorus can significantly improve the oxygen index, this is due to the burning of red phosphorus, with dehydration. Strong, prompting Al (OH) 3, Mg (OH) 2 dehydration crystallization heat, the flame retardant system of flame retardant effect.
Epoxy resin, flame retardant silicone is a new type of halogen-free flame retardant and smoke suppressant is a char type, it gives excellent flame retardant polymer type and mechanical strength can improve the processing performance and progress of materials, especially the low temperature impact strength. Has SFR100 silicone flame retardant silicone polymer market is a kind of transparent, viscous, and a variety of synergist (stearic acid salt, phosphoric acid and pentaerythritol amine mixture, aluminum hydroxide) and use, has been used for flame retardant polyolefin, low dosage can meet the general requirements of flame retardant, high dosage can be given excellent flame retardant material and smoke suppression.
Polyolefin containing 10%SFR100 can achieve the best balance among flame retardancy, activity and mechanical properties. Silicon processing additive for flame retardant system, reduce extrusion torque, but also a good dispersing agent, flame retardant progress in polymer dispersion, the mechanical properties of materials reduced; in addition, silicone is synergist flame retardant, the oxygen index can step in flame retardant system. Organosilicon has excellent thermal stability, which is determined by the nature of Si - O - bond which constitutes its main chain. The flash point of organic silicon is almost above 300 degrees, and it has flame retardancy.
In particular, the processing of silicone as long as the addition of general metal oxide, it can be made into UL - 94 grade silicone rubber. Due to the unique properties of silicone flame retardant, in 90s they will not use halogen flame retardant place to get more extensive application, with silicon compound flame retardant polymer will open new flame retardant materials market.
Flame retardant nano inorganic flame retardant compounds are generally high melting point, the processing temperature of synthetic materials, are based on the particle state in the system, in order to spread the progress of flame retardant, increase the fire retardant effect, general requirements for flame retardant particles as small as possible, a halogen-free flame retardant, superfine the surface modification of multi-component composite industry support, add low volume, high flame retardant efficiency.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
(A Small Cabinet Loaded With 16 Tons), 1000KG / IB Bucket (A Small Cabinet Installed 18 Tons) Or 23 Tons (1, 3-Dichloro-2-Propyl) Phosphate (TDCPP) Packing: Net Weight 200KG / ISOTANK.
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.
The particles of inorganic flame retardant are used generally in the micron level, filling a large amount of flame retardant, the flame retardant efficiency is not high, if the flame retardant nano particles as flame retardant, filling amount will be greatly reduced, the flame retardant efficiency will double the progress.
Nano materials with small size effect; surface and interface effect (with the decrease of nanometer size specific surface area increases rapidly, and the proportion of rapidly increasing number of surface atoms); quantum size effect and macroscopic quantum tunneling effect and other characteristics. Flame retardant polymers will be organic polymer, good flexibility, low density, easy processing and other advantages of inorganic filler strength and high hardness, good heat resistance, no deformation with height, has shown strong vitality.
Environmentally friendly flame retardant silicone rubber silicone rubber FR-103 environmental friendly flame retardant for the appearance of white powder, which is different from this type of flame retardant magnesium hydroxide, aluminum hydroxide, easy to add, high temperature resistance, light weight, less addition amount, high flame retardant efficiency; and will not affect the physical properties of silica gel, non stick rollers, no halogen, no corrosion of equipment and moulds, conform to the requirements of environmental protection. No need to add three antimony oxide two, high cost performance, low cost of flame retardant.
Flame retardant silicone rubber is widely used, can be used in silicone rubber, rubber, natural rubber, latex, fabric coating glue, liquid silicone rubber, polyester flame retardant, good thermal stability, flame retardant effect of high temperature vulcanized silicone rubber significantly. Packing: 20 kg / compound bag
Because the inorganic flame retardant mechanism by thermal decomposition to release steam to reduce the system of water vapor and temperature at the same time dilution of the combustible gas to the flame retardant effect which is based on the amount of water vapor to determine its flame retardant effect so the quantity is related to the flame retardant and flame retardant nano particles is generally independent of inorganic flame retardant the particle size distribution is enough in between.
