Unsaturated polyester coating flame retardant
2017-11-27 10:58:32
Unsaturated polyester coating flame retardant is an additive that can improve the flammability of unsaturated polyester coatings, prevent the unsaturated polyester coatings from being ignited and inhibit the flame spread. The research and development of fire retardant coating is closely related to the development of unsaturated polyester coating flame retardant. The choice of unsaturated polyester coating flame retardant and flame retardant system plays a key role in the performance of fire retardant coatings.
Unsaturated polyester resin products have the advantages of high strength, small proportion, corrosion resistance, good insulation properties, and can be processed under normal temperature and atmospheric pressure, and so on, and they are widely used in industrial production. Unsaturated polyester resin is also a solvent free paint, its film is hard, bright, no penetration, aging resistance, corrosion resistance, high resistance (low) temperature, generally used for sewing sewing machine bedplate, TV and radio shell, piano shell and all kinds of wooden furniture paint.
In 1990, the world's flame retardant dosage was about 500 thousand T, 85% of which was additive flame retardant, 15% was reactive flame retardant, and aluminum hydroxide accounted for about 50% of the total amount. In the United States all kinds of flame retardants, aluminum hydroxide flame retardant in recent years, the annual growth rate is higher than 30%.
In contrast, the development of magnesium hydroxide is late, in addition to the above advantages of aluminum hydroxide, it also has the characteristics of high decomposition temperature (its initial decomposition temperature is value=, "320" UnitName=, "temperature" >320 degrees Celsius). Magnesium hydroxide has been used in polypropylene, polyethylene and unsaturated polyester coatings abroad.
The by-product of seawater salt making in China, magnesium chloride and the newly discovered brucite in Liaodong area all provide abundant raw material sources for magnesium hydroxide. At the same time, the surface treatment technology in our country is also gradually strengthened, which will greatly promote the development of this kind of flame retardant.
Sb2O3 is one of the first inorganic flame retardants, and its use is only inferior to aluminium hydroxide. The amount of Sb2O3 used as flame retardant abroad accounts for about 1/2 of its total consumption. Antimony production in China ranks first in the world, and the amount of flame retardant is about 8000~8500t per year, of which Sb2O3 is 2500~3000t, while that of Sb2O3 used for flame retardants is only 300t.
Phosphorus and phosphorus compounds are the most important types of flame retardants. At present, the demand for halogen-free and phosphorus based flame retardants on the market is increasing rapidly. The flame retardant efficiency of phosphorus based flame retardant can be improved and the amount of use can be reduced. The new phosphorus containing flame retardant can minimize the mechanical strength loss caused by plasticizing effect of ordinary phosphate ester.
Such as two kinds of ammonium polyphosphate (APP), one of the APP compounds Exolit422 than the market all the products of high molecular weight, good thermal stability, low solubility, its whiteness coefficient is 90~95.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.
Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.
Another product, Exolit462, has the same chemical properties as Exolit422, but its surface is coated, which inhibits its chemical reaction with other additives and improves its moisture resistance, which is especially suitable for outdoor use.
Boron containing flame retardants mainly include zinc borate (ZB) and barium borate, which is non-toxic, low water solubility, high thermal stability, fine particle size, good dispersion characteristics, especially ZB, as a kind of multifunctional additives, flame retardant, carbonization, smoke suppression and other performance, the use of a very widely.
MoO3 and sodium molybdate can be combined with Al (OH) 3 and Sb2O3 to produce synergistic flame retardancy and smoke suppression effect. Other inorganic compounds, such as three hydrate aluminum (ATH), magnesium and boride, which are mainly used in flame retardant, smoke abatement and corrosion resistance systems, have a tendency of narrow particle size distribution and tend to be tiny or submicroscopic. By treating ATH, the size range of particles was reduced to improve its rheological properties. At present, 0 - 25 m ultrafine varieties are being developed.
Ultrafine zinc borate (ZB) Flamtardz series product, whose particle size is less than 1 m, can be used as a good flame retardant and smoke suppressant. By increasing the purity of natural magnesium hydroxide, its cost can compete with that of ground ATH, and now there are varieties with average particle size less than 3 m. In addition, the development of coating technology improves the wettability and impact resistance of flame retardant additives.
The research and production of flame retardant started late in China, but it developed rapidly. The flame retardant system has formed from scientific research to production, from inorganic to organic, from single type to compound type.
The flame retardant finishing of polyester fabric with IFR, PEL and MEL of APP, 4A zeolite and aqueous polyacrylate (PA) as flame retardant has good flame retardant effect. It has better handle, low smoke and color difference during combustion, better than brominated flame retardant, poor water resistance and brominated flame retardant. There are Exolitap, IFR, Budit and Spinltam MF series intumescent flame retardants for phosphorus and nitrogen compounds used in plastics abroad.
