Problems solved by technology

However, in the actual test, it is found that most of the warm baby products currently on the market do not match their labels, and their maximum temperature is much higher than the label temperature
This will bring certain safety hazards, such as continuous high temperature may cause burns to the skin

Abstract

The invention relates to the field of daily necessities, and discloses a two-component heating sticker with staged heating, which includes a waterproof outer packaging bag and a water storage bag adhered to one side of the inner surface of the waterproof outer packaging bag; There is a water injection hole, and a sealing plug is provided in the water injection hole, and a protrusion for extruding the sealing plug is provided on the inner surface of the water storage bag facing the water injection hole; the water storage bag is filled with water, and the waterproof outer packaging bag, The water storage bag is filled with quicklime microcapsules, vermiculite and water-absorbing resin; the quicklime microcapsules are quicklime powder coated with a modified N-isopropylacrylamide polymer, and part of the quicklime microcapsules are also coated with paraffin wax , and the paraffin wax melting points on the surface of different quicklime microcapsules are different. The heat preservation patch of the present invention adopts quicklime and water as heat sources, and compared with iron powder, it has a faster heating speed; and the quicklime powder is microencapsulated differently, so that the quicklime can react in stages, and the heat preservation time of the heat preservation patch is improved. more durable.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a two-component heating patch with staged heating. Background technique [0002] In recent years, especially in winter, baby warmers have become one of the necessary daily necessities for young people. At present, the reaction principle of most warm babies on the market is to use primary batteries to speed up the oxidation reaction and convert chemical energy into heat energy. [0003] Most of the existing baby warmers are mainly composed of a heating material layer based on iron powder, a gelatin layer, a non-woven bag with a microporous air-permeable film, and an airtight outer bag. When in use, the outer bag is removed, and the inner bag (non-woven bag) is exposed to the air, and the oxygen in the air enters the exothermic raw material layer through the gas-permeable film and reacts exothermicly with the iron powder. The principle of the reaction is to use the primary batter...
