Zeolite coated nasal mask and disposable particulate respirator filtration media

摘要

A method and use of Zeolite coated nasal mask and disposable particulate respirator filtration media that will absorb air pollutants such as NOx, Ozone, PM2.5 and radioisotopes of cesium, strontium and polonium (the progeny of radon gas) and protect the wearer from inhalation of said deleterious agents.

1. A Method of producing mechanical air filtration media and nasal mask and disposable particulate respirator filtration media containing absorbent materials such as Clinoptilolite or Phillipsite (Zeolite) as radiation, radioactive isotope and air pollution absorbing/trapping agents dissolved in de-ionized water along with a retention aid and a sealant polymer (Curie Formula) coated onto woven or nonwoven (polypropylene) fabric comprising:
a) the step of mixing radiation and air pollution absorbing materials ˜60-80% zeolite and correspondingly 40-20% boehmite (retention aid) binder in de-ionized water (5:1 ratio) at pH 8-9, specifically 8.5-8.9 at 28-30° C., specifically 28.8° C., and an organic polymer containing Hydroxypropylcellulose (HPC)+Ethoxylated Methyl Glucoside (EMG) (Methyl Gluceth-20)˜60%:40% (ratio) (sealant) (to minimize particle separation from the substrate creating dust), for two (2) minutes, then, b) the step of applying (spraying or dipping) or coating the absorbing material onto a woven or nonwoven (spunbond/meltblown polypropylene) fabric permanently sealing said material. This HEPA tested (0.3 microns) air filtration media maybe coated with a Mayer rod. The bottom (first layer) dry aim thickness is 1.8 mil and the top (or sealant) layer is 1.4 mil, air penetration is 0.001-0.003.
