ANTI-FREEZE AGENT FOR ROADS WITH CONTROLLED EMISSIONS CAPABLE OF STABLY PREVENTING FREEZING BY CONTROLLING EMISSION RATES OF A FREEZING POINT DEPRESSING AGENT BY AN ABSORBER AND TACKIFIER

摘要

PURPOSE: An anti-freeze agent for roads is provided to control emission rates of a freezing point depressing agent, thereby being fast-acting and durable.;CONSTITUTION: An anti-freeze agent for roads comprises: 35-75 weight% of C2-6 water-soluble polyhydric alcohol; 20-60 weight% of one or more kinds of porous adsorbent selected from a group consisting of activated carbon, zeolite, and activated alumina; and 0.01-10 weight% of a thickener selected from xanthane, acrylic polymer, or a mixture thereof. The water-soluble polyhydric alcohol is one or more selected from a group consisting of ethylene glycol, propylene glycol, glycerin, dimethylene glycol, sorbitol, isositol, and manitol.;COPYRIGHT KIPO 2012
