Detailed ways

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Example 1

As shown in Figure 1-2, the utility model provides a new type of fireproof cable harness, which includes a harness body 1, and a number of pressing pieces 2 are arranged at both ends of the harness body 1, and the pressure pieces 2 are evenly spaced. Notch grooves 3 are provided, and cutting lines 4 are set between the notch grooves 3. Several fireproof strips 5 are attached to the surfaces on both sides of the wire harness body 1, and a base plate 6 is arranged in the middle of the wire harness body 1. The outer surface of the substrate 6 is wrapped with an airgel felt layer 7 , and the outer surface of the airgel felt layer 7 is wrapped with a refractory layer 8 .

Further, the fireproof strip 5 is mainly made of magnesium hydroxide flame retardant material, the substrate 6 is mainly made of memory metal, and the magnesium hydroxide in the fireproof strip 5 is a new type of filled flame retardant, which can be decomposed by heat When it releases bound water, it absorbs a large amount of latent heat to reduce the surface temperature of the synthetic material it fills in the flame, which can inhibit the decomposition of the polymer and cool the combustible gas produced, which can effectively flame-retardant and further prolong To ensure the service life of the harness body 1, the substrate 6 is mainly made of memory metal, which is an alloy, which can be made into a shape at a low temperature, and then can be changed after heating. It returns to the original shape, has memory, is widely used in all walks of life, and is easy to use and operate.

The refractory layer 8 is mainly made of unsaturated resin material. The unsaturated resin has good properties of heat resistance, water resistance, dilute acid and dilute alkali, and is convenient for production and processing.

The surfaces of the fire strip 5 and the refractory layer 8 are all coated with flame retardant paint, double-layer secondary fire prevention, effective flame retardancy, and further prolonging the service life of the wire harness body 1 .

Specifically, both ends of the wire harness body 1 are provided with a number of pressing pieces 2, which are convenient for pressing and transporting, and there are notch grooves 3 between the pressing pieces 2, which are convenient for cutting and cutting according to the consumption requirements. There are cutting lines 4 between the notch grooves 3, which not only facilitates cutting, but also make the appearance of the wire harness cut by the cutting lines 4 beautiful, and at the same time do not damage the performance of the wire harness body 1, the two sides of the wire harness body 1 There are a number of fireproof strips 5 attached to the surface, among which the fireproof strip 5 is mainly made of magnesium hydroxide flame retardant material, which has good fireproof and flame retardant properties and can also cool down, protecting the service life of the cables inside the wire harness. There is a substrate 6 in the middle of the inside of the body 1. The substrate 6 is mainly made of memory metal and has good restorative properties. The memory shape of the substrate 6 can be produced and processed according to the type of cable required. The outer surface of the substrate 6 is wrapped with Airgel felt layer 7. The heat insulation effect of airgel felt is 2-5 times that of traditional heat insulation materials. Airgel felt is absolutely water-repellent, which can effectively prevent moisture from entering the interior of pipes and equipment, and has A1-level fireproof performance in buildings , and the unique three-dimensional network structure of airgel avoids the obvious decline in the insulation effect of other insulation materials such as sintering deformation and settlement during long-term high-temperature use. Pipes and equipment of different shapes are insulated, and the time and manpower required for installation are less. It is convenient to use and further ensures the service life of the cables inside the wire harness and the life of the wire harness.
