Detailed Description
In order to make the description of the present invention more complete and thorough, illustrative descriptions are provided below for embodiments and specific embodiments of the present invention, but this is not the only form in which embodiments of the present invention may be implemented or utilized. The various embodiments disclosed below may be combined with or substituted for one another where appropriate, and additional embodiments may be added to one embodiment without further recitation or description. In the following description, numerous specific details are set forth to provide a thorough understanding of the following embodiments. However, embodiments of the invention may be practiced without these specific details.
Fig. 1 is a schematic perspective view illustrating a flame retardant composite fabric 100 according to an embodiment of the present invention. Referring to fig. 1, a flame retardant composite fabric 100 includes a base fabric 110 and a flame retardant polyurethane film 120.
The base fabric 110 may serve as a base material of the flame-retardant composite fabric 100. In more detail, when the flame retardant composite fabric 100 is applied to an end textile, the base fabric 110 may be, for example, a base material of the end textile. In some embodiments, the base fabric 110 may be, for example, a hump-resistant base fabric, and thus the flame-retardant composite fabric 100 may be applied as life-saving medical supplies, such as medical beds, life rafts, Avalanche bags (Avalanche bags), and the like. The manufacturing method of the base fabric 110 may be, for example, weaving, injection molding, etc., and in some embodiments, the fabric weight of the base fabric 110 may be, for example, 50 to 150 g/m.
The flame-retardant polyurethane film 120 is disposed on the base fabric 110, and the flame-retardant polyurethane film 120 has a thickness of 0.1 to 0.2 mm. The flame-retardant polyurethane film 120 may provide the base fabric 110 with a flame-retardant effect. In other words, the flame retardant polyurethane film 120 can provide the flame retardant composite fabric 100 and the end product to which the same is applied with a flame retardant effect.
In some embodiments, the flame retardant polyurethane film 120 may include 89.5 to 92.5 parts by weight of polyurethane and 1.5 to 4.5 parts by weight of a phosphorus-based flame retardant. The polyurethane can be, for example, a thermoplastic polyurethane (ThermoplasticPolyurethane), which is suitable as an adhesive and has a flame-retardant effect. Therefore, when 89.5 to 92.5 parts by weight of polyurethane is used as the material of the flame-retardant polyurethane film 120, the flame-retardant polyurethane film 120 and the base fabric 110 have excellent interfacial compatibility, so that the flame-retardant polyurethane film 120 can be fixed on the base fabric 110. In addition, since polyurethane itself has a flame retardant effect, it can provide basic flame retardancy to the flame retardant polyurethane film 120. The phosphorus-based flame retardant contains phosphorus (P) and has a flame-retardant effect. More specifically, when the phosphorus-based flame retardant is burned by heat, it may generate metaphosphoric acid to cover the surface of the burning object to isolate the external oxygen from entering and prevent the internal combustible gas from escaping, thereby achieving the flame retardant effect. Therefore, when 1.5 to 4.5 parts by weight of the phosphorus-based flame retardant is used as an additive for the flame-retardant polyurethane film 120, the flame retardancy of the flame-retardant polyurethane film 120 can be further improved.
It is worth noting that, since the flame-retardant polyurethane film 120 includes 89.5 to 92.5 parts by weight of polyurethane and 1.5 to 4.5 parts by weight of phosphorus-based flame retardant, the flame-retardant polyurethane film 120 can be regarded as an intrinsic flame-retardant film material and has good adhesion with the base fabric 110. Therefore, when the flame retardant composite fabric 100 includes the base fabric 110 and the flame retardant polyurethane film 120 well adhered thereto, the flame retardant composite fabric 100 has better washing fastness compared to the conventional flame retardant textile directly coated with the flame retardant. In addition, the flame retardant polyurethane film 120 does not contain halogen and is a halogen-free flame retardant film material compared to the conventional halogen-containing flame retardant material, so the flame retardant composite fabric 100 including the flame retardant polyurethane film 120 is an environment-friendly fabric.
In some embodiments, the flame retardant polyurethane film 120 may further include 0.1 to 0.5 parts by weight of a synergistic flame retardant and 3 to 4.5 parts by weight of a char-forming agent. The synergistic flame retardant can improve the flame retardant effect of the phosphorus flame retardant. In detail, the synergistic flame retardant may include a catalyst of a phosphorus-based flame retardant, which can improve the flame retardant efficiency of the phosphorus-based flame retardant, thereby improving the flame retardant effect of the phosphorus-based flame retardant. On the other hand, the char-forming agent can increase the char formation amount during the combustion reaction to form a more compact char layer on the surface of the combustion product, thereby facilitating the improvement of the flame retardant effect.
In some embodiments, the flame retardant polyurethane film 120 further includes 0.1 to 0.5 parts by weight of a dispersant or an antioxidant. The dispersing agent can improve the dispersibility of the phosphorus flame retardant, the synergistic flame retardant and the char-forming agent in the flame-retardant polyurethane film 120, so that the additives are more uniformly distributed in the flame-retardant polyurethane film 120. The antioxidant mainly functions to maintain the physical properties of the polyurethane in the flame-retardant polyurethane film 120 when the film is formed, for example. Specifically, since the film-forming process of the flame-retardant polyurethane film 120 may include a step of heating the polyurethane film 120, and the step of heating the polyurethane film may cause the polyurethane in the flame-retardant polyurethane film 120 to lose its original physical properties by oxidation, the addition of the antioxidant can prevent the above-mentioned phenomenon, and the polyurethane can maintain its original physical properties after the flame-retardant polyurethane film 120 is formed.
In some embodiments, the flame retardant polyurethane film 120 may be formed by subjecting flame retardant polyurethane particles and pure polyurethane particles to a hybrid curtain coating process. The pure polyurethane particles are understood to mean virgin polyurethane particles, i.e. particles which do not contain further additives and are formed from pure polyurethane. Conversely, the flame retardant polyurethane particles may include other additives such as phosphorus flame retardants, synergistic flame retardants, char formers, dispersants, antioxidants, and the like. In some embodiments, it is preferable to use a ratio of 3: 7, and forming the flame-retardant polyurethane film 120 by a film-coating molding process.
It is worth mentioning that, the utility model discloses a when fire-retardant polyurethane film 120 is through polyurethane, phosphorus system flame retardant, synergistic flame retardant, char-forming agent, dispersant and/or the antioxidant including above-mentioned part by weight, can make fire-retardant polyurethane film 120's primary material have better film forming property when drenching membrane shaping processing procedure to make fire-retardant polyurethane film 120 have good surface uniformity. Preferably, in one embodiment, the flame retardant polyurethane film 120 includes 92.5 parts by weight of polyurethane, 2.4 parts by weight of a phosphorus-based flame retardant, 0.3 parts by weight of a synergistic flame retardant, 4.5 parts by weight of a char-forming agent, and 0.3 parts by weight of an antioxidant. In yet another embodiment, the flame retardant polyurethane film 120 preferably includes 92.5 parts by weight of polyurethane, 3.9 parts by weight of a phosphorus-based flame retardant, 0.3 parts by weight of a synergistic flame retardant, 3 parts by weight of a char-forming agent, and 0.3 parts by weight of an antioxidant.
To sum up, the utility model provides a fire resistance composite cloth, it includes base cloth and fire-retardant polyurethane film, wherein fire-retardant polyurethane film has specific proportion's polyurethane, phosphorus flame retardant, synergistic flame retardant, char former, dispersant and antioxidant, therefore base cloth and fire-retardant polyurethane film have good adhesion, so the utility model discloses a fire resistance composite cloth has good washing fastness. In addition, based on the specific weight ratio of the components, the flame-retardant polyurethane film has good film forming property and surface uniformity. Moreover, the flame-retardant polyurethane film does not contain halogen, so the flame-retardant composite fabric is an environment-friendly fabric.
