In order to reduce the heat dissipation on the heating mantle 3 and to increase the heat transfer efficiency and the heating rate of the gas in the cavity 31, the side of the heating mantle 3 remote from the heat conducting means 1 is coated with a layer of composite insulating material 32, the composite insulating material 32 typically being 1-3cm thick. The composite heat-insulating material 32 comprises the following components in parts by weight: 2-4 parts of epoxy resin, 5-8 parts of Fe2O3-HNTs (hydrogenated nitrile butadiene styrene) hybrid material, 12-14 parts of asbestos powder, 0.1-0.3 part of polyphenylene sulfide, 0.2-0.3 part of m-cresol, 0.1-0.3 part of dopamine, 0.1-0.3 part of early strength agent, 3-5 parts of steel fiber, 0.3-0.5 part of dimethyl silicone oil and 0.2-0.4 part of toughening agent.

As the HNTs halloysite nanotubes contain a large number of cavities, asbestos powder can be filled into the nanotubes, thereby generating a heat insulation effect. The epoxy resin is matched with the polyphenylene sulfide, the m-cresol and the dopamine to seal the asbestos powder in the nano tube, so that the asbestos fiber is effectively prevented from drifting into the air in the use process, and the environmental pollution is avoided.
Example 2:

The composite heat insulating material 32 was prepared in the following weight fractions and coated on the back surface of the heating mantle 3 to prepare a sample ii:
2 parts of epoxy resin, 8 parts of Fe2O3-HNTs (hydrogenated nitrile-butadiene rubber) hybrid material, 14 parts of asbestos powder, 0.1 part of polyphenylene sulfide, 0.3 part of m-cresol, 0.1 part of dopamine, 0.2 part of early strength agent, 4 parts of steel fiber, 0.5 part of dimethyl silicone oil and 0.2 part of toughening agent.

In addition, the three samples are placed in an environment of 100 ℃ for long-term experiments, and the results show that the composite heat-insulating material 32 can be continuously used for at least ten years in the environment of 100 ℃ without cracking, falling off or serious oxidative denaturation, and when the environmental temperature is lower than 100 ℃, the service life of the composite heat-insulating material is further prolonged.
