Abstract

The utility model discloses a 450-plus-750V environment-friendly fire-resistant electric wire for home decoration, which comprises a conductive material which is in accordance with GB/3956 and uses copper/aluminum as a medium, wherein a ceramic silicon adhesive tape layer is arranged outside the conductor, and heat-resistant 125 ℃ anti-cracking, rat-proof, termite-proof, low-smoke halogen-free and flame-retardant cross-linked polyolefin is arranged outside the ceramic silicon adhesive tape layer; the utility model has the advantages that: because the ceramic silica gel tape is adopted for insulation, the ceramic silica gel has good flexibility and tensile strength, and is suitable for high-speed winding. The ceramic silica gel tape generates ceramic after catching fire at high temperature and is converted into a rigid self-supporting ceramic product, so that the conductor can be effectively protected from being damaged.

Description

450-grade 750V fireproof/environment-friendly fireproof electric wire for home decoration

Technical Field

The patent relates to a 450-plus-750V environment-friendly fireproof, ratproof and termite-proof electric wire for home decoration, belonging to the field of electric wires.

Background

At present, the electric wires in the home decoration market are various, common flame-retardant electric wires are generally adopted for decoration, and along with the gradual national regulation of the building market, the requirements on the electric wires for home decoration are gradually improved from the safety perspective. Because the traditional home decoration electric wire in China adopts the phlogopite tape fireproof layer, the phlogopite has poor performance at normal temperature, is easy to generate embrittlement phenomenon during combustion, causes short circuit of the electric wire and is easy to cause safety accidents, and in addition, the common electric wire is easy to be bitten by termites and rats to influence the use and cause safety accidents due to various factors such as areas in the north and south and climate and the like.

In order to solve the problems, the utility model discloses a 450 supple with 750V environment-friendly fire-resistant electric wire for house ornamentation, fire prevention, protection against rodents, nontoxic, environmental protection, security height use under the illumination that still can last the circular telegram under the specific conditions, rescue, warning etc. is nontoxic nuisanceless.

The technical scheme of the utility model is that:

450-750V environment-friendly fire-resistant electric wire for home decoration comprises a conductor, a wrapping layer and an insulating layer. The conductor is a conductive material which conforms to GB/3956 and takes copper/aluminum as a medium; the wrapping layer is a ceramic silica gel tape which can be magnetized into crystals after being heated to high temperature and attached to the conductor, so that the integrity of the insulating layer is ensured; the insulating layer is made of low-smoke halogen-free flame-retardant cross-linked polyolefin which is resistant to cracking at 125 ℃, rat and termite, and the molecular structure of the insulating layer is changed from linear to network to generate cross-linking reaction through UVL ultraviolet irradiation equipment in the body at the high temperature of 350-420 ℃ after being heated and extruded and molded by a plastic extruding machine at 220-175 ℃, so that the weather resistance and the aging resistance of the insulating layer are improved.

The utility model has the advantages that:

1. the product has low price and can replace the common flame-retardant products

2. No moisture absorption and no water absorption, and the storage life can be as long as 1-30 years;

3. the fireproof grade is high and can reach A grade, and the fireproof grade of the fireproof wire and cable produced by the ceramic fireproof and fireproof composite belt can reach the A grade standard of GB12666.6 through a spraying and vibration experiment;

4. the safety is high, and the smooth circuit can be ensured under the condition of fire;

5. the flame retardant property is excellent, and the flame retardation is not delayed;

6. the mechanical property is excellent, and the electrical insulation property is excellent;

7. the used materials are harmless to human bodies, low smoke, halogen-free, phosphorus-nitrogen-free, heavy metal-free, nontoxic and harmless, and the safety level of the smoke toxicity reaches the safety level ZA1 level of the high polymer materials; no toxic smoke is generated after the combustion,

8. excellent high and low temperature resistance, ozone resistance and ultraviolet aging resistance; the use temperature is as follows: minus 70 ℃ to plus 200 ℃.

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.

Example 1

As shown in figure 1, the 450-charge 750V environment-friendly fire-resistant electric wire for home decoration comprises a conductor which is in accordance with GB/3956 and made of a conductive material with copper/aluminum as a medium, a ceramic silica gel band is arranged outside the conductor, and the ceramic silica gel band is externally provided with 125 ℃ heat-resistant, anti-cracking, rat-proof, termite-proof, low-smoke, halogen-free and flame-retardant cross-linked polyolefin.

The manufacturing method is the same as the traditional wire manufacturing process, ceramic silica gel tape double-layer winding covering is carried out on the cross section of the conductor, and then anti-cracking, anti-rat, anti-termite, low-smoke halogen-free and flame-retardant cross-linked polyolefin is used for extrusion molding.

According to the process requirements:
