Abstract

A raw material for water electret melt-blown cloth, comprising 120-130 parts of polypropylene resin, 3-5 parts of zirconium dioxide powder, 1-2 parts of light calcium carbonate, and 0.5-1 part of polyvinylamine in parts by weight , 5-7 parts of anionic polyacrylamide, 3-5 parts of oxidized polyethylene wax, 2-4 parts of volcanic stone powder; the one-step production process of the water electret melt-blown cloth includes the production of melt-blown cloth, the preparation of electret water, Electret process, drying process. The advantages of the water electret melt-blown cloth of the present invention include: it can guarantee that no electrostatic decay will occur within 5 years; no discoloration and mildew will occur after 100 standard washings; the moisture content of the melt-blown cloth after drying can be controlled to 5%‑6%; the filtration efficiency is 98.9%‑99.5%, and the filtration efficiency can still reach 98.5%‑99.1% after 100 standard washings.

Description

One-step production process of water electret meltblown cloth technical field The present invention relates to the production field of meltblown cloth, especially relate to the one-step production technology of water electret meltblown cloth. Background technique The difference between water electret melt-blown cloth and the melt-blown cloth of traditional process manufacturing is: what traditional melt-blown cloth uses is corona It shows significantly stronger stability and comprehensive benefits; and water electret meltblown cloth is prepared by high-pressure water pump Pure water is delivered to the nozzle, and the melt-blown cloth is sprayed by the fan-shaped nozzle, and static electricity is generated by friction between the two. Water electret meltblown The performance of the cloth is that the amount of static electricity is saturated, but the attenuation is faster, and the water electret meltblown cloth is compared with the traditional electrostatic electret me...
