Polyurethane foam (PUF) used flame retardant
Polyurethane foam (PUF) were also involved with flame retardants add type and reaction type in gathered in phosphonic acid ester, phosphate ester, phosphate ester, phosphonic acid ester, phosphorus - nitrogen reactive phosphonic acid ester and a lot of new compound with flame retardant system. In this paper, some of the low - core polyurethane foam plastics (PUF) with flame retardant are described in detail.
In recent years, development and production of polyurethane foam (PUF) with flame retardant (FR), most of them is halogen-free, model, and the high efficiency and low fog value and low VOC (VolatileOrganicContent), comply with the environmental protection and flame retardant laws increasingly stringent requirements.
Polyurethane foam (PUF) were also involved with flame retardants add type and reaction type in gathered in phosphonic acid ester, phosphate ester, phosphate ester, phosphonic acid ester, phosphorus - nitrogen reactive phosphonic acid ester and a lot of new compound with flame retardant system. In this paper, some of the low - core polyurethane foam plastics (PUF) with flame retardant are described in detail. In addition, the paper also discusses the changes that PUF currently faces with FR.
Hard and soft polyurethane foam (RPUF and FPUF) is one of the largest users of halogen-phosphor flame retardant (FR), which is mainly additive. At present, the most dosage is still three (beta-chlorisopropyl) phosphate (TCPP) and 3 (beta, beta '-dichloro-propyl) phosphate (TDPP).
This is because of their rich raw material source, manufacturing and use of mature technology, low price, in adding appropriate amount of polyurethane foam (PUF), they can satisfy users of PUF flame retardancy and other comprehensive performance of the basic requirements, also can through the fog value.
Regarding the impact of TCPP and TDPP on ecology and human health, the eu is evaluating [2] and has not yet published its final report. According to the existing experimental results, and from "substitute must mature in technology, and feasible in economy" principle, the authors estimate, in a relatively long period of time, and TDPP TCPP in many application areas, also will be temporarily allowed. But in some applications, there may be limits, and the total amount will be reduced.
Of course, it is imperative to include TCPP and TDPP in the emission reduction plan, namely, to minimize and control their emissions to the environment, while closely monitoring their retention in the environment. Another double phosphate ester containing halogen, i.e., 2, 2 - (methyl chloride) 2-1, 3 - and propyl four double phosphate (beta - ethyl chloride), commonly known as V6, it is applied in the PUF, its influence on the ecological environment and human health is also under the eu evaluation.
The main problem facing V6 is to minimize the content of three (beta - chloroethyl) phosphate (TCEP). In PUF, other types of halogen-phosphorus, halogen, phosphorus, nitrogen and other FR were also available, but their dosage was lower than TCPP and TDPP. In the long term, the unhalogenation of FR is the development trend and the target of people's pursuit. Therefore, some halogenated FR (including TCPP, TDPP, V6) of PUF should be treated with caution.
This article does not discuss the FR that is being used in PUF in the above mentioned, but only in recent years has industrialized production been used for the new type FR of PUF. Most of them is halogen free, many of which are oligomer, with high efficiency and low VOC (VolatileOrganicCompound, low volatile organic compounds), the characteristics of low fog value.
Tris(2-chloroisopropyl)Phosphate(TCPP)
Cas No:13674 -84-5
HS Code HS: 29199000
The most important indicator of product:
colorless transparent liquid, moisture ≤ 0.1, Acid value ≤ 0.1, Chroma ≤ 50, the phosphorus content: 9.4 ± 0.5
Raw materials: phosphorus oxychloride and epichlorohydrin.
Belong to several categories of dangerous goods:
Currently Tris(2-chloroisopropyl)Phosphate TCPP general cargo exports are not dangerous.
The product is used for the soft / hard polyurethane foam, with thermal and hydrolytic stability good, especially suitable for ASTME84 (Level 11) foam, with low viscosity unsaturated polyester resin in low temperature application and phenolic plastics at. This product is also used to grab the foam sealant and sheet production. For polyvinyl chloride, polystyrene, phenolic resin, acrylic resin and rubber, coating, flame retardant, also used for soft and hard polyurethane foam, epoxy resin, polystyrene, cellulose acetate, ethyl cellulose tree and phenolic plastics, polyvinyl acetate and gun type foam sealant production. Particularly recommended for rigid polyurethane foam has excellent thermal and hydrolytic stability is particularly suitable for ASTM84 (II), compound for polyurethane foam and unsaturated resin and phenolic plastics.
In recent years, RPUF and FPUF have faced some important changes in FR:
(1) as chlorofluorocarbons (CFC) foaming agent disabled, pentane types of foaming agent (including cyclopentane, isopentane, are pentane and their mixture are PUF (especially RPUF) used as the substitutes of CFC. Obviously, the category of pentane than CFC foaming agent of high flammability, new foaming agent to compensate for this defect, need to increase dosage of PUF FR, or improve the isocyanate index of PUF, which formed in PUF more isocyanate structure unit. Therefore, PUF expects more efficient FR.
(2) due to the banning of pentabromodiphenyl ether (PeBDPO), the PUF of a new low-fired core needs to be opened with FR. Sales in the market a few years ago with isopropyl PeBDPO three aryl phosphate mixed FR, used to burn with FPUF core is low, very user welcome, but since 2004, due to the disabling of PeBDPO stop production.
(3) due to the increasingly stringent requirements of environmental protection, PUF manufacturers and users prefer FR without halogen, low VOC, low fog value. Low-poly or reactive FRS can solve this problem well and have been introduced in recent years.
(4) introduction of new flame retardant regulations. In the United States, for example, the FPUF CAL117 test standard for mattresses is currently being revised. If the revised flame retardant requirement is higher, it is possible to influence the flame retardant pathway of the mattress, such as the use of an anti-flammable lining, rather than flame retardant FPUF. Polyimide, polyaromatic amide, polybenzimidazole fabric and glass cloth can be used as the lining for the flame retardant of mattresses.
Polyurethane foam is the most important part of all kinds of polyurethane products. Its main feature is that it is porous and therefore relatively low in density and high in strength. According to the different raw materials and formula changes, it can be made into soft, semi-rigid and hard polyurethane foam. The varieties of polyols used in the classification can be classified into polyester, polyether and castor oil polyurethane foam. If according to its foaming methods classification has a block, molding and spraying polyurethane foam plastic and other types.
