Abrégé
(EN)
The invention relates to a water-based environment-friendly anti-corona tape. An electrician impregnates an alkali-free glass filament braid or polyester non-woven fabric tape in a glue solution, andthe alkali-free glass filament braid or polyester non-woven fabric tape is dried and cured to acquire the anti-corona tape. The glue solution comprises a mother solution. By taking the total mass of the mother solution as 100%, the raw material ratio of the mother solution is 18% to 45% water-based resin and 55% to 82% water. According to the invention, water-based resin and water are used to replace solvent-type resin and a volatile solvent, which greatly reduces the amount of volatile organic compounds discharged from a product, and minimizes physical injury to workers; the problem that theenvironmental protection property of anti-corona glue used by a traditional anti-corona tape is not up to the standard is solved; the water-based environment-friendly anti-corona tape has the advantages of environmental protection, low VOC content, low toxicity, small odor and convenient use; and production equipment can be washed with water, which saves a lot of solvents.
