Description

Technical Field

[0001] The utility model relates to the field of composite profiles, in particular to a high-performance flame-retardant composite profile. Background Art

[0002] Composite profiles are made from a combination of two or more different materials. Their structure and properties offer significant advantages, combining the strengths of various materials to create a new type of functional material. Composite profiles offer advantages such as high strength, light weight, corrosion resistance, and environmental friendliness. Composite profiles are widely used in a variety of fields, including construction, transportation, aerospace, electronics, and sports equipment, and are a vital component of modern industrial and technological development.

[0003] In the existing composite profile structure, the profile adopts a single-layer flame retardant structure, which has a good flame retardant and heat-insulating effect on the outer surface of the profile. For the inner surface, the flame retardant and heat-insulating property is poor, which affects the flame retardancy of the entire profile. In addition, in the existing composite profile, a straight plate is set as the longer side of the profile, and the supporting effect of the straight plate is poor, resulting in average strength of the entire profile. At the same time, only one circular hole is set in the middle position of the profile structure, which is prone to deformation under the action of external force, thereby affecting normal use.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 3 As shown, a high-performance flame-retardant composite profile includes a profile fixing strip 1, to which a corrugated connecting plate 2 is connected. A circular tube 3 is provided in the space between the two corrugated connecting plates 2, and a fixed connecting plate 4 is provided on the circular tube 3. An elliptical tube 5 is provided in the space between the two corrugated connecting plates 2, and a first support plate 6 and a second support plate 7 are provided on the elliptical tube 5. The profile is composed of a supporting base layer 10, a flame-retardant and heat-insulating layer 11, a reinforcing layer 12, a first surface layer 13, and a second surface layer 14. A first through hole 8 is provided in the profile fixing strip 1, and a second through hole 9 is provided in the profile fixing strip 1 near the first through hole 8. The fixed connecting plate 4 is fixedly connected to the profile fixing strip 1, and a support strip is provided on the fixed connecting plate 4, which is fixedly connected to the corrugated connecting plate 2.

[0019] The corrugated connecting plate 2 is fixedly connected to the profile fixing strip 1, the first support plate 6 is fixedly connected to the fixed connecting plate 4, the second support plate 7 is connected to the profile fixing strip 1, and the elliptical tube 5, the first support plate 6 and the second support plate 7 are symmetrically arranged relative to the circular tube 3.

[0020] During the use of the profile, the profile fixing strip 1 cooperates with the circular tube 3 and the fixed connecting plate 4 to provide basic support, while the elliptical tube 5, first support plate 6, and second support plate 7 arranged between the two corrugated connecting plates 2 provide further support. When the profile is subjected to external force, the corrugated connecting plate 2 can absorb the external load, thereby dispersing the stress and making the stress distribution more uniform, avoiding stress concentration and reducing deformation and damage of the profile caused by excessive local stress. At the same time, the first support plate 6 and the second support plate 7 transfer part of the force to the elliptical tube 5, while the fixed connecting plate 4 and the support strip transfer part of the force to the circular tube 3. The circular tube 3 and the elliptical tube 5 further disperse the force, making the force more uniform, improving the strength of the entire composite profile, making the profile less prone to deformation and damage under stress, and extending its service life. The first through hole 8 and the second through hole 9 set on the profile fixing strip 1 can reduce the weight of the profile while also allowing for the insertion of related connecting structures, improving the use effect of the profile.

[0021] Through the above embodiment, two layers of flame-retardant and heat-insulating layers 11 are symmetrically arranged on the supporting base layer 10, and the flame-retardant and heat-insulating layers 11 are fixedly connected to the supporting base layer 10. Glass fiber and flame-retardant cotton are embedded in the flame-retardant and heat-insulating layers 11, and carbon fiber is provided in the reinforcement layer 12, and the reinforcement layer 12 is fixed to the flame-retardant and heat-insulating layers 11 on the upper surface of the supporting base layer 10. The first surface layer 13 is fixed to the flame-retardant and heat-insulating layers 11 on the lower surface of the supporting base layer 10, and the second surface layer 14 is arranged on the reinforcement layer 12, and the second surface layer 14 is fixedly connected to the reinforcement layer 12.

[0022] During the use of the profile, the supporting base layer 10, as the main component of the profile, provides basic support in the various layered structures that make up the profile, ensuring the profile's strength in use. The flame-retardant and heat-insulating layers 11 on both sides of the supporting base layer 10 act as flame-retardants and insulation, ensuring that the entire composite profile has good flame retardancy and will not deform or damage in high-temperature environments, thus ensuring the effectiveness of use. Carbon fibers are arranged within the reinforcing layer 12 to increase the strength of the composite profile, ensuring that the profile is lightweight while maintaining good strength. The first surface layer 13 and the second surface layer 14, as the outermost parts of the profile components, protect the internal layered structure and have high wear resistance, allowing the profile to be used for a long time, with a simple structure and good performance.

[0023] It should be noted that the wave connecting plate 2 is provided, and the wave-shaped structure can well absorb external loads, making the stress distribution more uniform, and there will be no stress concentration, reducing the risk of excessive local stress, and increasing the strength of the entire composite profile. In addition, the wave-shaped structure has a strong ability to absorb energy, and the composite profile is not easy to deform when subjected to stress. The elliptical tube 5 is provided, and is used in conjunction with the first support plate 6 and the second support plate 7. When the composite profile is subjected to stress, it can further disperse the force, improve the use strength of the composite profile, and extend the service life of the composite profile. Flame-retardant and heat-insulating layers 11 are provided on both sides of the supporting base layer 10, which improves the flame-retardant and heat-insulating effect of the entire composite profile, ensures that the composite profile is non-flammable, and increases the use effect. Carbon fibers are provided in the reinforcing layer 12 to ensure the strength of the profile, and the first surface layer 13 and the second surface layer 14 have high wear resistance, so that the profile can be used for a long time.
