Portable exothermic agent and preparation method thereof

The invention discloses a portable exothermic agent which is prepared from the following raw materials in parts by weight: 4-6 parts of expanded vermiculite powder, 3-4 parts of water, 10-12 parts ofactivated carbon, 73.9-89.9 parts of iron powder, 1 part of table salt and 1-5 parts of ionic liquid. In addition, the invention also provides a preparation method of the portable exothermic agent, which comprises the following steps: 1) mixing water, table salt and ionic liquid to form a mixed solution; and 2) adding expanded vermiculite powder, activated carbon and iron powder into the mixed solution, and uniformly mixing all the components to obtain the heat generating agent. The components of the heat generating agent provided by the invention contain less water, so that the heat generating temperature can reach 91 DEG C, and the heat generating time can reach more than 30 minutes. 本发明公开了一种便携式发热剂，按重量份数计，其原料组成包括：膨胀蛭石粉4～6份，水3～4份，活性炭10～12份，铁粉73.9～89.9份，食盐1份，离子液体1～5份。此外，本发明还提供了一种便携式发热剂的制备方法，包括以下步骤：1)将水、食盐、离子液体混合形成
