Foamed Buffer Material Made from Fibers of Old Newspaper

Abstract

The foamed plastics are not bio-degradable and not readily recyclable. How to substitute new foamed buffer materials with lower pollution for foamed plastics became a popular research topic. The paper discussed the effects of microwave power, natural bonding agent, lubricating agent and crosslink agent on foamed buffer material with fibers of old newspaper and inorganic foaming agent. The result showed that increasing of microwave power could be beneficial to decrease the molded time and density of foamed buffer material with fibers of old newspaper. The best foamed properties were achieved with proper dosage of natural bonding agent like wheat flour, glyceryl monostearate sodium borate at the microwave power of 575W.
