Low-tightness non-carbonization solid electrolytic capacitor paper and preparation method thereof

The invention belongs to the field of electrolytic capacitor paper, and particularly relates to low-tightness non-carbonization solid electrolytic capacitor paper and a preparation method thereof. Theelectrolytic capacitor paper comprises the following raw materials by dry mass: 10-80% of jute pulp and 20-90% of chemical fiber, the pulping degree of the jute pulp is 10-30 degrees SR, the wet weight of the jute pulp is 10-40g, the length of the chemical fiber is 1.5-15 mm, and the fineness of the chemical fiber is 0.1-3 dtex. The low-tightness non-carbonization solid electrolytic capacitor paper provided by the invention has good adsorbability to conductive polymer monomers, and can reduce side reactions during polymerization of the conductive polymer monomers, and the low-tightness non-carbonization solid electrolytic capacitor paper has low tightness, so that the monomers can be uniformly distributed in the paper. Therefore, the capacitor paper does not need to be subjected to carbonization treatment in the
