The invention relates to the field of papermaking, and discloses a high-strength insulating steel paper and a preparation method thereof. The insulating steel paper is formed by gluing and bonding several layers of base paper; it is prepared from the following raw materials in parts by weight: 140-160 parts of wood pulp, 4-6 parts of sisal fiber, 300-500 parts of reinforced dipping emulsion, swelling 200-400 parts of gelling solution, 8-12 parts of cellulose gas phase gel particles, 4-6 parts of fish bone meal, 0.5-1.5 parts of ethylene glycol diglycidyl ether, and 4-6 parts of fish bladder extract gel. The insulating steel paper of the invention has high tensile strength and high interlayer peeling strength, and can meet the current market demand; and the material is green and environmentally friendly, and the preparation process is simple and reasonable, and is suitable for large-scale production. |
