Description

Technical Field

[0001] The utility model relates to the technical field of knife scraping cloth design, and particularly relates to a new type of knife scraping cloth with flame retardant and fire prevention properties. Background Art

[0002] Knife scraping cloth, also known as spray painting cloth, is mainly a kind of spray painting material used for outdoor advertising spray painting production. It is widely used in coated canopies, light boxes, background boards, and wide-format advertising pictures in public places. Ink is sprayed on its surface to form its unique advertising display. Advertising devices are basically set outdoors and are relatively vulnerable to factors such as sunlight, rain, and day-night temperature differences, reducing their service life. Existing knife scraping cloth is usually fixed with a fixed bracket, and the structure of the fixed bracket is relatively bulky, easily causing friction with the fixed position of the knife scraping cloth, resulting in easy damage to the knife scraping cloth and affecting its service life. The advertising panel is easily affected by sunlight temperature and mirror refraction outdoors, posing a risk of spontaneous combustion or being ignited, creating a safety hazard for the use of the knife scraping cloth. Therefore, a new type of knife scraping cloth with flame retardant and fire prevention properties is proposed. Content of the Utility Model

[0024] Referring to Figures 1 to 4 , the embodiment of the present utility model provides a novel knife-coated fabric with flame retardant and fireproof performance, including a front fiber layer 1 and a back fiber layer 12. A first adhesive layer 3 is provided at the bottom of the front fiber layer 1. A first adhesive sheet 4 is provided at the bottom of the first adhesive layer 3. A transverse covering layer 7 is provided at the bottom of the first adhesive sheet 4. A second adhesive sheet 10 is provided at the bottom of the transverse covering layer 7. A second adhesive layer 11 is provided at the bottom of the second adhesive sheet 10. A flame retardant and wear-resistant layer 13 is provided at the bottom of the second adhesive layer 11. The front fiber layer 1 and the back fiber layer 12 are respectively set as the front and back contact fabrics of the knife-coated fabric structure. The first adhesive layer 3 and the second adhesive layer 11 are symmetrically arranged with respect to the transverse covering layer 7. The bottom of the front fiber layer 1 is bonded to the top of the first adhesive layer 3 to realize the structural setting of the front cloth surface of the knife-coated fabric. The bottom of the first adhesive layer 3 is adhered to the first adhesive sheet 4 to establish an adhesion with the front cloth surface of the transverse covering layer 7. The bottom of the transverse covering layer 7 is adhered to the second adhesive layer 11 through the second adhesive sheet 10 to establish a connection with the back fiber layer 12. The setting of the flame retardant and wear-resistant layer 13 can provide wear resistance and flame retardant performance for the knife-coated fabric, improve the safe use performance of the knife-coated fabric. The specific structure of the knife-coated fabric is composed of the pressing of multiple layers of fabrics, so that it has the use structural performance of the knife-coated fabric. With the setting of multiple layers of flame retardant materials, the protection of the knife-coated fabric structure is enhanced, so that it can reflect a good fire protection effect.

[0025] Referring to Figure 4, the horizontal covering layer 7 is made of a wavy fabric. The cavity between the horizontal covering layer 7 and the first adhesive sheet 4 is set as the first filling layer 5. A set of upper longitudinal skeletons 6 are respectively arranged in the troughs of the horizontal covering layer 7. The cavity between the horizontal covering layer 7 and the second adhesive sheet 10 is set as the second filling layer 8. A set of lower longitudinal skeletons 9 are respectively arranged in the peaks of the horizontal covering layer 7. By using the peaks of the wavy design of the horizontal covering layer 7 to accommodate multiple sets of lower longitudinal skeletons 9, and using the troughs of the wavy design of the horizontal covering layer 7 to accommodate multiple sets of upper longitudinal skeletons 6, the structural performance of the knife-coated fabric can be enhanced by setting the upper longitudinal skeletons 6 and the lower longitudinal skeletons 9, enhancing the toughness and strength of the fabric, avoiding tearing of the knife-coated fabric under stress, and extending the service life of the knife-coated fabric. The fabric structure of the first filling layer 5 realizes the control of the structural stability of the upper longitudinal skeletons 6 to avoid displacement of the upper longitudinal skeletons 6. The fabric structure of the second filling layer 8 realizes the control of the structural stability of the lower longitudinal skeletons 9 to avoid displacement of the lower longitudinal skeletons 9.

[0026] The first filling layer 5 and the second filling layer 8 are respectively filled with aerogel. The aerogel will only melt when the temperature reaches 1200 degrees Celsius, which can effectively enhance the support performance of the two filling layers.

The top surface of the first adhesive layer 3 is bonded to the adhesive layer 103 by means of the surface adhesive layer 301 to ensure the stability of the connection between the two groups of fabrics. The setting of the high-pressure polyethylene layer 302 can achieve the sealing setting of the knife-coated fabric, enabling the knife-coated fabric to be used in outdoor rainy and humid environments. The setting of the inner adhesive layer 303 realizes the connection to the first adhesive sheet 4.

[0031] A number of contact tentacles 304 are evenly provided at the bottom of the inner adhesive layer 303. The external contact tentacles 304 at the bottom of the inner adhesive layer 303 are connected to the first adhesive sheet 4 to prevent looseness between the first adhesive sheet 4 and the inner adhesive layer 303.
