Description
Technical Field
The invention belongs to the technical field of energy storage high-voltage wire bundles, and particularly relates to a flame-retardant temperature-resistant ultraviolet-resistant energy storage high-voltage wire bundle and a preparation process thereof.
Background
With the increasing demand for electricity in today's society, high voltage wiring harnesses play a vital role in power transmission systems. However, conventional high-voltage wire harnesses often use silicone rubber as an insulating material, and although silicone rubber has a wide range of applications in many fields, silicone rubber has some significant drawbacks in terms of high temperature resistance, flame retardancy and ultraviolet resistance. These disadvantages limit the range of applications in harsh environments, making it impractical for use in certain applications. For example, under high temperature conditions, silicone rubber may soften or even melt, resulting in a decrease in its physical and mechanical properties and failure to continue to function properly. In addition, silicone rubber is also deficient in flame retardant properties and is easy to burn, which is a great risk in some environments where fire safety is required. Meanwhile, the silicon rubber has weak resistance to ultraviolet rays, and long-term exposure to ultraviolet rays accelerates the aging process of the silicon rubber, so that the service life of the high-voltage wire harness is shortened. Therefore, to overcome these deficiencies, it is desirable to modify silicone rubber or find other alternative materials to meet the needs of applications in harsh environments.
Disclosure of Invention
The invention aims to provide a flame-retardant temperature-resistant ultraviolet-resistant energy-storage high-voltage wire harness and a preparation process thereof, which are used for improving the flame-retardant temperature-resistant ultraviolet-resistant aging performance of silicone rubber.
The aim of the invention can be achieved by the following technical scheme:
The preparation process of the flame-retardant temperature-resistant ultraviolet-resistant energy storage high-voltage wire harness is characterized in that the flame-retardant temperature-resistant layer tightly wraps a modified silicone rubber material A outside the wire core in an extrusion continuous vulcanization mode, and the anti-aging sheath layer tightly wraps a modified silicone rubber material B outside the flame-retardant temperature-resistant layer in an extrusion continuous vulcanization mode to form the anti-aging sheath layer.
As a preferable technical scheme of the invention, the preparation method of the modified silicone rubber material A comprises the following steps:
A1, mixing 5,10,15, 20-tetra (4-vinyl phenyl) porphyrin, monovinyl end-capped polydimethylsiloxane and dibenzoyl peroxide, heating at 65 ℃ for 5-7h, and heating to 120 ℃ and preserving heat for 3-5h to obtain a material A;
