Specifically, as shown in fig. 2, in this step, the glass fiber cloth is a cloth to be rolled, and the glass fiber cloth after being glued is a finished cloth roll. The glass fiber cloth 1 is conveyed to a material groove 3 through a roller, the material groove 3 is soaked with the hanging glue, and the glass fiber cloth 2 after the glue is hung is obtained after the glass fiber cloth enters a high-temperature tunnel 4 for solidification and rolling after the glass fiber cloth is quantitatively extruded by the roller.

And 3, coating the two sides of the rubberized glass fiber cloth in the step 2 with the fireproof flame-retardant heat-insulating material prepared in the step 1 by adopting an extrusion casting method. Specifically, as shown in fig. 2, the glass fiber cloth coated with glue in this step is a feeding cloth roll, and the fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth is a finished cloth roll. And (3) quantitatively conveying the rubberized glass cloth 1 in the step (2) through a roller, then quantitatively extruding the fireproof flame-retardant heat-insulating material prepared in the step (1) by a die to cast the rubberized glass cloth, and finally, entering a high-temperature tunnel 4 for curing and rolling to obtain the fireproof flame-retardant heat-insulating explosion-proof cloth 2.

< Experimental example >

When the cable is used, the fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth is cut according to the diameter of the cable to be protected, and the cut fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth completely covers the cable and is fixed by the binding belt.

The fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth prepared in the five embodiments is cut according to the diameter of a cable to be protected, the cut fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth completely covers the cable and is fixed by a binding belt, and then a combustion experiment is performed on the cable covered with the fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth. The fire-resistant flame-retardant heat-insulating explosion-proof cloth prepared in the five examples is subjected to weather resistance experiments and aging experiments.

Experiments prove that the flame-retardant temperature of the flame-retardant cable can reach more than 350 ℃, and after the flame-retardant cable burns at the temperature of more than 350 ℃, the cable wrapped by the flame-retardant, heat-insulating and explosion-proof cloth is not damaged.

A large number of experiments prove that the fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth can be used at the temperature of-40-80 ℃, which shows that the fire-resistant, flame-retardant, heat-insulating and explosion-proof cloth has good weather resistance.

Experiments prove that the fireproof flame-retardant heat-insulating explosion-proof cloth can be used for more than 15 years under outdoor conditions and can be used for more than 20 years under indoor or buried conditions.

The fire-resistant flame-retardant heat-insulating material, the fire-resistant flame-retardant heat-insulating explosion-proof cloth and the preparation method are not limited to the scope of the specific embodiments. The above description is only a basic description of the present invention, and any equivalent changes made according to the technical solution of the present invention should fall within the protection scope of the present invention.
