Cellulose and wool flame retardants
Melting and/or degradation and/or dehydration require a large amount of heat (for example, the preparation of inorganic and organic phosphorus in the back coating, aluminum hydroxide or hydrated alumina). Usually not used for cellulose and wool flame retardants; It is more common in natural refractory and heat-resistant fiber (such as aromatic polyamide fiber).
Most of the phosphorous and nitrogen containing flame retardants of cellulose and wool; The heavy metal complex in wool. Hydrated and certain flame retardant can release water; Halogen halogen can be released by halogen flame retardant. Halogen flame retardant, often combined with antimony oxide. As can be seen from the above, certain cellulose and wool flame retardants can be used in a variety of ways, most effective examples. In addition, some of the flame retardant fiber and wool can produce liquid medium, the intermediate can be wet fiber surface, thus become the insulation and oxygen barrier - widely accepted boric acid salt - mixture of boric acid can play a role in this way.
In addition, it can also promote carbon. To simplify the classification of chemical flame-retardant behaviors, the term 'condensing' is used to distinguish them from 'gas or steam' phase activities. Both are compound items, which include the above (a ~ c) methods, which include (d) and (e) methods. Physical mechanism usually work at the same time, these include mechanism formed by coating to eliminate oxygen and/or heat (d), increase the heat capacity (a) and use the flammable gas dilution or override the flame (d).
Whether the fiber can be soft and/or melt determines whether it is thermoplastic. Thermoplastic due to its related physical changes can seriously affect the behavior of flame retardants. Traditional thermoplastic fibers (for example, polyamides, polyesters and polypropylene) shrink away from the flame and thus avoid being ignited: this makes them appear to be flame-retardant on the surface.
In fact, if contractions are blocked, they burn. This so-called stenting effect can be seen on polyester cotton and similar blends, i.e. molten polymer melts to non-thermoplastic cotton and is ignited. Similar effects can be seen on composite textiles composed of thermoplastic and non-thermoplastic components.
Isopropylphenyl Phosphate(IPPP35) Use
The Product Is Used For Rubber Products And PVC Plastic Flame Retardant Conveyor Belt, Cable, Chloroprene Rubber, Rubber And Other Synthetic Rubber Flame Retardant Plasticizer, Isopropylphenyl Phosphate Flame Retardant IPPP35 Use Also Applies To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin, And Other Fields.
Isopropylphenyl Phosphate Flame Retardant IPPP35 Halogen-Free Phosphate Flame Retardant Plasticizer, Which Does Not Pollute The Environment Twice. It Is The Lowest In The Phosphate Species And Has The Highest Phosphorus Content. This Product Is Colorless And Transparent, Good Compatibility, The Use Of Both Flame Retardant And Plasticizer, In The Flame Retardant And Plasticizer To Play A Balance Between The Role, But Also To Make The Processing Of The Same Material And Its Physical Properties.
As the effect of molten drops (usually with flame drop), although the drip drip can remove heat and flame front flame (and therefore can 'through' vertical flame test), but it can make in its surface (such as carpet or skin burn or secondary lit.
Most during mass production or as a finishing agent on the use of traditional synthetic fiber flame retardants are usually by enhancing melting drip drip and/or for help with flame drop out play a role in one of two ways. So far, nothing has been done to reduce thermoplastic and to promote a large amount of carbon, as is the case with the flame retardant cellulose (including viscose fiber).
Urea and the role of softening agent: structure contains high amount of urea nitrogen, and flame retardant fiber and wool coordinating role, thus improve the flame retarding performance and reduce the dosage of the flame retardant fabric. However, the amount of urea should be adjusted to the amount of flame retardant.
Fiber and wool flame retardants suitable baking for: temperature 150 ℃, 3 ~ 4 minutes. After baking, oxidized by a moderate amount of water to wash, can be flame retardant polymer may contain all of the condition of low phosphorus oxide into a + 5 price high phosphorus, and can improve the flame retardant fiber and wool washing resistance and flame retardant properties of the fabric after processing.
After treatment of fabric with cellulose and wool flame retardant, their residual and smoldering time were 0. This indicates that phosphoric nitrogen flame retardant has good synergistic effect. Because of the relatively small element structure of cellulose and wool flame retardants, it has good permeability and easy to penetrate into the fiber, so it is easy to produce polymers with fabrics.
The increase of fabric is less important than the cellulose and wool flame retardants, indicating that the flame retardant may be attached to the fiber surface. After 20 washes, the damage length of cellulose and wool flame retardants has not changed significantly. This also reflects their good washing resistance.
