Technical Field
[0001] The utility model relates to the technical field of polyester cloth, in particular to a high-efficiency fireproof polyester cloth. Background Art
[0002] Polyester fiber, also known as polyester, is a man-made synthetic fiber made from polyester compounds. Polyester has some remarkable characteristics, such as durability, wrinkle resistance, ironing resistance, and non-stickiness. These characteristics make polyester fiber widely used in textiles, home furnishings, automobiles and other fields.
[0003] Current polyester fibers themselves do not have fire-resistant properties, which means that clothing made of polyester fibers cannot be used in some special scenarios and has a relatively limited range of wear. Polyester fibers melt easily at high temperatures, which increases the risk of rapid combustion in a fire. During the combustion process, polyester fibers will emit smoke and produce toxic gases, which may pose a threat to personal safety. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-3 As shown, a high-efficiency fire-resistant polyester cloth comprises a polyester cloth base 1, a fire-resistant coating 2, a fire-resistant film 3, a heat-resistant film 4 and an anti-ultraviolet film 5. The fire-resistant coating 2 is arranged above the polyester cloth base 1, the fire-resistant film 3 is arranged on the surface of the fire-resistant coating 2 away from the polyester cloth base 1, the heat-resistant film 4 is arranged between the fire-resistant film 3 and the anti-ultraviolet film 5, and the anti-ultraviolet film 5 is arranged above the heat-resistant film 4; the utility model has excellent flame retardancy. When encountering a fire source, it can quickly extinguish the flame and effectively prevent the spread of fire, thereby protecting people's lives and property. Moreover, the polyester cloth can still maintain stable performance in a high-temperature environment, is not easy to deform or melt, and is suitable for various high-temperature working environments. This feature makes the high-efficiency fire-resistant polyester cloth have broad application prospects in the fields of chemical industry, petroleum, medicine, etc.
[0019] The polyester cloth base layer 1 includes polyester fiber 11 and polyphenylene sulfide fiber 12, and the polyester fiber 11 and the polyphenylene sulfide fiber 12 are blended with each other. The polyphenylene sulfide fiber 12 is a fiber material with excellent flame retardant properties. It itself has good flame retardant properties, can maintain stability at high temperatures, is not easy to burn, and produces less smoke and toxic gases when burned. After the polyester fiber 11 and the polyphenylene sulfide fiber 12 are blended, the polyester fiber 11 can enhance the overall strength and wear resistance of the fabric, and at the same time complement the polyphenylene sulfide fiber 12 to jointly improve the comprehensive performance of the fabric, thereby improving the fire resistance of the entire fabric.
[0020] The fire-retardant coating 2 is a halogen flame retardant fire-retardant coating, and the fire-retardant film 3 is an acrylic fire-retardant film. The halogen flame retardant fire-retardant coating can decompose at high temperature to produce inert gases such as hydrogen halide, thereby diluting the oxygen concentration in the combustion area to achieve a flame retardant effect. The acrylic fire-retardant film is made of acrylic ester as the main raw material and is prepared by polymerization. The film has both high fire resistance and good mechanical properties and processing properties.
[0021] The heat-resistant film 4 is a polytetrafluoroethylene film, and the anti-ultraviolet film 5 is a PMMA anti-ultraviolet film. The polytetrafluoroethylene film has excellent heat resistance and can improve the overall heat resistance of the fabric so that the fabric can be used in a high temperature environment. Long-term exposure to ultraviolet rays may reduce the flame retardant properties of the polyester cloth. The PMMA anti-ultraviolet film is set to improve the anti-ultraviolet ability of the fabric.
[0022] An anti-tear layer 7 is provided above the polyester fabric base layer 1, and a fire retardant coating 2 is coated on the surface above the anti-tear layer 7. The anti-tear layer 7 is nylon fiber, which improves the overall toughness of the fabric.
[0023] The surface above the anti-ultraviolet film 5 is coated with a chemical-resistant coating 6, and the chemical-resistant coating 6 is a polyurethane coating, which not only has good chemical resistance, but also can improve the warmth and comfort of the fabric, further improving the practicality of the polyester cloth.
[0024] Working principle: When the polyester cloth is in use, the polyphenylene sulfide fiber 12 inside the polyester cloth and the set fire-retardant coating 2 and fire-retardant film 3 make the polyester cloth have good fire-retardant performance. When a fire occurs, the polyester cloth can effectively resist the flame. In addition, a heat-resistant film 4 is provided inside the polyester cloth, so that the polyester cloth can be used in a high-temperature environment. When the polyester cloth is placed in the sun, the anti-ultraviolet film 5 can effectively resist ultraviolet rays and effectively protect the fire-retardant coating 2 and fire-retardant film 3 inside the polyester cloth to avoid a decrease in fire-retardant performance. The chemical-resistant coating 6 on the surface of the anti-ultraviolet film 5 can block external chemical corrosives, further improving the service life of the polyester cloth.
[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
