Publication number: 20130081770Abstract: A method is provided for manufacturing eco-friendly inorganic paper, which has a composition comprising inorganic glass powder that is greater than 51% but not greater than 75%, 25-40 wt % bonding substance comprising polypropylene (PP) (comprising mixture of polylactic acid (PLA) or PP and polyethylene (PE)), and 1-5 wt % assisting agents, through a process of continuous compression molding that includes step one to step six. As such, the paper so made, after being disposed of can be subjected to incineration of the constituent of PP, which is of a minor fraction, so as not to generate high temperature, smoke, and toxicant gases and to allow the inorganic powdery residuals of the incineration to be returnable to the earth and the nature.Type: ApplicationFiled: September 29, 2011Publication date: April 4, 2013Inventors: CHUN-TENG HUANG, Chun-Ming Huang
