Flame retardant of polyolefin resin
Currently on the market a lot of inorganic flame retardant polyolefin resin varieties, common market can really play a role alone is the main flame retardant magnesium hydroxide, aluminum hydroxide, zinc borate, such as three, two oxidation of antimony, brucite series, and organic soil can only be regarded as flame retardant synergist, their main role is to help other organic flame retardant synergistic flame retardant polyolefin resin, the other flame retardant efficiency can be improved.
The type of nitrogen and phosphorus matching polyolefin resin flame retardant is a hot spot in the market, including intumescent flame retardants composed of melamine, pentaerythritol, ammonium polyphosphate (APP) and so on.
The market and application of different flame retardant and its flame retardant material characteristics, the application effect of the best, the largest amount of application in polyolefin flame retardant varieties are halogen containing flame retardant, the bromine series flame retardant, in particular to DecaBDE such as the most widely used, because the European market introduced environmental protection directive RoHS, the life cycle of the near end of decabromodiphenyl oxide, decabromodiphenyl oxide and is replaced by bromine content and thermal stability, the molecular structure is similar to the ten bromo two benzene ethane flame retardant, ten bromo two benzene ethane combustion does not produce carcinogenic dioxin and flame retardant efficiency and suitable resin and process and DecaBDE is almost the same, and the cost of raw materials, with other flame retardants do not have the advantage, therefore it is widely spread.
The specific application of the process, bromine series flame retardant ten bromo two ethyl benzene represented in a thermoplastic resin with high flame retardant efficiency, the mechanical properties of materials prepared, the requirements of the production process is not complicated, easy processing, good compatibility with plastic resin, can be relatively simple by adding flame retardant agent melt blending produce good flame retardant performance, and material properties not changed much of the flame retardant materials. In addition, the biggest advantage of bromine series flame retardants lies in its high cost performance and recyclability, and long-lasting flame retardancy. In contrast, it is more suitable for electrical appliances, automobiles, interior decoration and other high-grade materials flame retardant.
Of course, bromine series flame retardant also has its own weaknesses, such as the burning of black smoke, have certain corrosive, even some products also have toxicity and so on, but in the current process conditions and technical conditions, it is still the most common market, especially engineering plastics and plastic thermoplastic resin to the processors the product.
Triphenyl Phosphate (TPP)
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.
Brominated flame retardants include a variety of brominated organic compounds, which are used in various plastics and other materials to prevent burning and fire spread. Currently, PBDEs, HBCD, TBBA are the three most brominated compounds used most. Most brominated flame retardants are stable in the environment, especially the accumulation of PBDEs in some organisms.
Long term exposure can interfere with brain and skeletal development, which can lead to permanent effects on the nervous system and behavioral abilities, such as learning and memory decline. Brominated flame retardants also harm the hormonal system, which is also a potential endocrine barrier in the estrogen channel. Through animal experiments found that certain brominated flame retardants will lead to growth retardation, delayed puberty and adverse effects on the liver and fetal development and immune system. All brominated flame retardants produce dioxins and furans when they are incinerated. They are serious carcinogens.
Most brominated flame retardants are fat soluble and easy to accumulate in the human body. The use of the European Union have restricted part of brominated flame retardants, polybrominated diphenyl ether (PBDE) in two of the five bromo two phenyl ether (PentaBDE) and eight bromo two phenyl ether (OctaBDE) has been banned in 2004, on the restriction of Hazardous Substances Directive (RoHS), polybrominated biphenyls (PBB) and two polybrominated diphenyl ether (PBDE) and the maximum allowable amount is 0.1%.
At present, more and more people prefer green flame retardants, because brominated flame retardants will produce toxic smoke when burning. Therefore, halogen free flame retardants are vigorously implemented, so halogen free flame retardants are environmentally friendly and safe. Research institutions believe that brominated flame retardants can significantly reduce the burning of toxic gases in polymer combustion, which is conducive to the protection of the environment. In the two voices, bromine flame retardant application prospect is controversial, the future trend is to let the industry deeply puzzled.
The tungsten complex flame retardant can be used directly to treat all kinds of wool fabrics, and the wool fabric can also be treated by flame retardant dyeing in one bath. Features: high flame resistance, strong washing resistance, color, hand feel, strength remain unchanged, smoke less. Sodium phosphotungstate - organic acid system of flame retardant finishing on wool, sodium 7% phosphotungstic acid solution respectively with oxalic acid, malonic acid, succinic acid mixed with acetic acid and pH was adjusted to 3, from 80 to 90 DEG C, stirring heating for an hour, and then the wool blended yarn was immersed into the 10min solution removed, washed drying.
