Title: Antifreezing agent and method for producing the antifreezing agent
Inventor: HANAMATSU NORIMITSU
IPC: C09K3/00
Filed: 2002-04-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide an antifreezing agent, making it possible that melting ability against a temperature condition of snow and ice is improved, even when a substance having comparatively low ability in antifreezing properties is used, and capable of being produced at a low cost.  <P>SOLUTION: This antifreezing agent is obtained by coating a granular core agent 1 used as a core with a coating agent 2 having the melting ability comparatively higher than that of the core agent 1. The core agent 1 preferably comprises calcium acetate, and the coating agent 2 preferably comprises potassium acetate. Because the potassium acetate is brought into contact with the snow and ice at an initial stage in melting the snow and ice, the antifreezing agent exhibits high melting properties even at a temperature of -20°C, and the snow and ice are melted to a certain extent. Then, the core agent comprising the calcium acetate is exposed, so that the core agent functions and the snow and ice is further melted to form water. Now, the function of the core agent is enough utilized due to action of formed water, etc., because the melting has proceeded to the certain extent by the coating agent, although the melting ability of the core agent is lower than that of the coating agent.  <P>COPYRIGHT: (C)2004,JPO
