There is therefore a need for a flame retardant cable that can solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, solve traditional flame retarded cable that proposes among the above-mentioned background art and bring the problem of certain hindrance for the rescue in the burning.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a flame retarded cable, includes the cable body, the cable body includes the cable core, the outside parcel of cable core has the parcel layer, and parcel layer outer wall parcel has fire-retardant layer, fire-retardant layer outer wall parcel has the isolation layer, and the isolation layer outer wall is connected with the waterproof layer through strengthening the subassembly.
Preferably, the flame-retardant layer is made of cross-linked polyethylene, the insulating layer is made of a metal compound, and the waterproof layer is made of rubber.
Preferably, the specific material of the insulating layer is copper oxide or iron oxide.
Preferably, strengthen the subassembly and include interior enhancement layer, buffer layer and outer reinforcement layer, interior enhancement layer and outer reinforcement layer all are metal mesh grid, and the buffer layer is the rubber material.
Compared with the prior art, the utility model has the advantages and positive effects that,
the utility model discloses in, through being provided with fire-retardant layer, it has good heat resistance, insulating properties and resistant chemical characteristic, can guarantee fire-retardant effect to its combustion products mainly are water and carbon dioxide, and is less to the harm of environment, satisfies modern fire control safety's requirement.

Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations set forth in the following description of the specific embodiments.
As shown in fig. 1 and fig. 2, in the embodiment of the present invention: the utility model provides a flame retarded cable, includes cable body 110, and cable body 110 includes cable core 111, and the outside parcel of cable core 111 has parcel layer 112, and parcel layer 112 outer wall parcel has fire-retardant layer 113, and the parcel of fire-retardant layer 113 outer wall has insulating layer 114, and insulating layer 114 outer wall is connected with waterproof layer 118 through strengthening the subassembly.
The flame retardant layer 113 is made of cross-linked polyethylene, the insulating layer 114 is made of metal compound, and the waterproof layer 118 is made of rubber.
Crosslinked polyethylene has the advantage that,
heat resistance: the XLPE with the net-shaped three-dimensional structure has excellent heat resistance. It will not decompose and carbonize under 200 deg.C, its long-term working temp. can be up to 90 deg.C, and its thermal life can be up to 40 years.
Insulating property: XLPE keeps the original good insulation characteristic of PE, and the insulation resistance is further increased. The dielectric loss tangent value is very small and is not greatly influenced by temperature.
Mechanical properties: because a new chemical bond is established among macromolecules, the hardness, rigidity, wear resistance and impact resistance of the XLPE are all improved, thereby making up for the defect that PE is easy to crack due to environmental stress.
Chemical resistance characteristics: the environment-friendly flame-retardant rubber has strong acid and alkali resistance and oil resistance, combustion products of the rubber are mainly water and carbon dioxide, the environment is less damaged, and the requirements of modern fire safety are met.
Meanwhile, the isolation layer 114 controls the burning substances by the non-burning characteristic thereof, and prevents the fire from spreading.
The specific material of the isolation layer 114 is copper oxide or iron oxide.
The reinforcing component comprises an inner reinforcing layer 115, a buffer layer 116 and an outer reinforcing layer 117, wherein the inner reinforcing layer 115 and the outer reinforcing layer 117 are all metal woven meshes, and the buffer layer 116 is made of rubber.
Through the design of the inner reinforcing layer 115, the buffer layer 116 and the outer reinforcing layer 117, the overall strength of the cable body 110 is improved, and the impact on the cable body 110 can be buffered to protect the cable core 111.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiments into equivalent variations to apply to other fields, but all those persons do not depart from the technical contents of the present invention, and any simple modification, equivalent variation and modification made to the above embodiments according to the technical matters of the present invention still belong to the protection scope of the technical solution of the present invention.
