[0023] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example 1

[0024] Please combine Figures 1-4 , a high-stability impregnated paper of this embodiment includes:

[0025] The impregnated paper body 1 is evenly provided with pores 2, the diameter of the pores 2 is 1-1.5 mm, and the inner wall of the pores 2 is provided with a waterproof membrane 3, which is a polytetrafluoroethylene microporous membrane, which has the advantages of chemical resistance, flame retardancy, high temperature resistance, strong acid and alkali resistance, and non-toxicity.

[0026] The impregnated paper body 1 is provided with a moisture-proof layer 101, an impregnated paper layer 102, a high-density fiber layer 103, a waterproof layer 104, a fire-proof layer 105, a kraft paper layer 106 and a wear-resistant layer 107 from bottom to top. The moisture-proof layer 101, the impregnated paper layer 102, the high-density fiber layer 103, the waterproof layer 104, the fire-proof layer 105, the kraft paper layer 106 and the wear-resistant layer 107 are bonded by epoxy resin adhesive, which increases the firmness between the layers. The fire-proof layer 105 is a multi-layer aluminum polyester film, which has good barrier properties, heat resistance and chemical stability, as well as excellent heat sealing properties. The waterproof layer 104 is a polyurethane waterproofing agent, which has excellent elasticity and ductility, seamless overall waterproofing and excellent chemical resistance. The moisture-proof layer 101 is a biomass carbon powder moisture-proof layer. Specifically, it is pressed by biomass carbon powder and epoxy resin adhesive. There are pores inside the biomass carbon powder, and its main function is to be moisture-proof. The impregnated paper layer 102 is melamine impregnated paper.

[0027] The implementation principle of a high-stability impregnated paper in the embodiment of the present application is as follows: the moisture-proof layer 101 can not only prevent the intrusion of moisture, but also cooperate with the wear-resistant layer 107 to protect the internal stress balance of the impregnated paper body 1; the high-density fiber layer 103 can improve the durability and moisture-proofness of the impregnated paper body 1; the waterproof layer 104 can increase the waterproof effect of the impregnated paper body 1; the fire-proof layer 105 can increase the fire-proof effect of the impregnated paper body 1; the kraft paper layer 106 can improve the physical properties of the impregnated paper body 1; the wear-resistant layer 107 can increase the wear resistance of the impregnated paper body 1; and by uniformly providing pores 2 on the impregnated paper body 1, gases generated by different factors can be discharged in a timely manner, thereby avoiding the problem of bubbles in the impregnated paper body 1 due to gas accumulation, effectively ensuring the quality and performance of the impregnated paper body 1. At the same time, by providing a waterproof membrane 3 inside the pores 2, it is possible to prevent moisture from entering and affecting the various layers of the impregnated paper body 1, thereby ensuring the stability of the performance of each layer of the impregnated paper body 1. Example 2

[0028] This embodiment is further improved on the basis of the embodiment 1 in that the surface of the wear-resistant layer 107 is sprayed with a matte frosted spray layer, thereby increasing the wear resistance of the impregnated paper. Example 3

[0029] This embodiment is a further improvement on the basis of the embodiment 1 in that, in order to better discharge the gas in a timely manner, three different types of pores 2 are evenly formed on the impregnated paper body 1. The diameter of the first type of pores is uniform from top to bottom, the diameter of the second type of pores gradually increases from bottom to top, and the diameter of the third type of pores gradually decreases from bottom to top.
