Abstract

The invention relates to a method for preparing a self-heating material for a central heating unit.A high-polymer material and distilled water are added into a reaction kettle according to a certain mass ratio, heated to 80-100 DEG C and stirred to be completely dissolved, and a product A is obtained; the product A, electrolyte, a foaming agent and iron powder are mixed according to a certain mass ratio for granulation, the mixture is cooled into the gel state, and a product B is obtained; the product A, electrolyte, a foaming agent and iron powder are mixed according to a certain mass ratio for granulation, the mixture is cooled into the gel state, and a product C is obtained; the self-heating material is obtained by mixing the product B and the product C according to a certain mass ratio when used.The self-heating material has the advantages that heat can be emitted immediately without making contact with outside air or outside moisture and continuous heating can be achieved, and use requirements of the central heating unit can be well met.

Description

technical field [0001] The invention relates to a preparation method of a self-heating material used in a central heating unit. Background technique [0002] Self-heating products have been widely used in daily life and industrial fields, such as in medical care, heating and cooking, bringing convenience to people's lives. Existing self-heating products generally require contact with air or water to generate heat, and the heat release is slow. Most of them are disposable products with a short service life, so they cannot be applied to central heating units. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing self-heating materials used in central heating units. It has the characteristics of releasing heat without contacting outside air or outside moisture, and can continue to generate heat, so as to meet the needs of central heating units. [0004] In order to solve the above technical proble...
