Abstract

The invention relates to the technical field of chemical industry, in particular to a simple lamellar type self-heating element and a preparation method and application thereof. The simple lamellar type self-heating element is prepared from the following ingredients: pig iron powder, activated carbon, polypropylene fibers, xanthan gum, sodium carboxymethyl cellulose, sodium polyacrylate, industrial salt, vermiculite and water, wherein the sum of percentages of all the ingredients is 100%. The industrial salt and the water are mixed to form the simple lamellar type self-heating element, and the whole self-heating element is very thin and very small in size; meanwhile, a lamellar solid package is finally formed, and the problem of leakage of heating substances cannot be caused; and moreover, the content of the polypropylene fibers, the xanthan gum, the sodium carboxymethyl cellulose and the sodium polyacrylate in the self-heating element is low, so that the cost of the self-heating element is greatly reduced. The vermiculite is added, so that the heat preservation effect of the self-heating element is improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a simple sheet-type self-heating body and its preparation method and application. Background technique [0002] The self-heating body is a thermal paste (commonly known as "warm paste", "warm baby", "one paste heat", "warm baby", etc.) and is a key material for products used to keep the human body warm. Its basic principle is: put iron powder , charcoal powder, vermiculite, resin, salt, etc. are mixed in an appropriate proportion to make a self-heating body, which is put into a bag made of a microporous oxygen-permeable film covered with non-woven fabric, and an oxygen-insulating plastic is used externally. Outer bag packaging. When in use, tear off the plastic outer bag, and after the non-woven inner bag contacts the air, oxygen enters through the micropores of the non-woven fabric and oxidizes with the iron powder, thereby generating heat and achieving the effect of ...
