<p>A method of processing fire-resistant plastic molded products used in discarded TV casings or the like to reuse them as recycled fire-resistant plastics. A method of reprocessing fire-resistant plastics comprising the steps of pulverizing fire-resistant plastic molded products recovered from wastes containing fire-resistant plastic molded products, and surface-grinding the obtained pulverized products to scrape off 3-30 wt.% of the surface layer. The surface grinding can employ a dry cleaning process for scraping off the surface layer by allowing pulverized products or pulverized products and container walls to collide to one another. Recycled fire-resistant plastics obtained by this method can be used singly or by being blended with unused fire-resistant plastics similar to or dissimilar from the recycled fire-resistant plastics at a weight ratio of 5-95:95-5, and satisfies a UL standard V-0 or V-2 grade.</p> |
