Description

Steam eye mask for preventing low-temperature scalds and preparation method thereof Technical Field The invention relates to the technical field of eyeshields, in particular to a steam eyeshield for preventing low-temperature scalding and a preparation method thereof. Background The birth and development of the steam eyeshade come from the increasing importance of modern people on eye health and comfort. With the popularization of electronic devices and the acceleration of the pace of work and life, problems such as asthenopia, dryness, acid swelling and the like caused by long-time eye use are more common, and especially, the problems of late executive, student groups and staff frequently using electronic screens become main stranded people with eye problems. Although the traditional relieving modes such as cold compress and eye drops have certain effects, the traditional relieving modes have the limitations of inconvenient use, short effect and the like, and a convenient, safe and efficient eye care scheme is urgently needed in the market. In this context, vapor masks have evolved. The design sense integrates hot compress therapy and modern portable technology, and the self-heating temperature control material releases warm steam at 40-50 ℃ for 15-30 minutes when worn, so as to form a local constant-temperature damp-heat environment. The mild physical effect can promote the blood circulation of eyes, relieve the tension of muscles, moisten the skin around the eyes through steam, improve the dry symptom, and simultaneously help relax the mind and body by means of shading design, and has the function of helping sleep. Early vapor eyewear represented by japanese brands quickly occupied the market with fine temperature control technology and comfortable use experience, and subsequently developed hot flashes around the world. In technical iteration, the material is upgraded from the traditional polypropylene non-woven fabric to the more skin-friendly medical fabric, the heating element is developed from the iron powder oxidation type to the more stable sheet type, and the safety and the stability are obviously improved. Nowadays, steam eyeshields extend from single functional products to add diversified products such as herbal essence, fragrance adjustment and the like, meet individual demands of different people, and become necessary single products for daily eye protection and travel relaxation of modern people. The popularization of the health care product not only reflects the upgrade of the health consumption concept, but also reflects the deep fusion of science and technology and human care in life details. The core principle of the steam eyeshade is the controllable oxidation reaction of iron powder and oxygen. After the package is opened, air enters the inside of the eyeshade through the precise ventilation film, contacts with components such as iron powder, active carbon and the like, generates uniform heat and releases trace steam. The process is strictly regulated and controlled by the oxygen permeation rate of the breathable film, so that scalding caused by overhigh temperature or influence on the effect caused by overlow temperature is avoided. For example, sheet-type designs press the heater into a uniform sheet 1 mm thick, ensuring stable and durable heating, while early powder-type products may be locally overheated due to uneven material distribution. At present, a plurality of researches are carried out on a steam eyeshade, as patent number CN116785060B discloses a high-moisture-retention steam eyeshade and a preparation method thereof, the steam eyeshade is obtained by adopting a sericin cotton layer, a polypropylene non-woven fabric layer, a heating sheet, a polyethylene layer, an ear hook and essence as raw materials and adding traditional Chinese medicine components and hydrogel into the heating sheet for lamination, and the steam eyeshade can relieve symptoms such as dry eyes, pain and the like generated after excessive or ultraviolet light stimulation, and the essence can be rapidly absorbed by skin to moisten the skin. Also, as disclosed in patent number CN110652394a, "double-layer steam eyeshade and method for producing the same," comprising eyeshade body and double-layer medicine bag, the steam eyeshade has the effects of promoting blood circulation of eyes, improving eyesight and refreshing, and the like, and has simple process and high production efficiency. However, most of the vapor eyeshade in the market is unstable in temperature control, and the mixing uniformity of heating materials is not high, and meanwhile, the problem of low-temperature scalding exists, so that it is highly desirable to develop a vapor eyeshade which can generate heat uniformly and prevent low-temperature scalding effectively. Disclosure of Invention The invention aims to provide a low-temperature scald preventing steam eyeshade and a preparation method thereof, which are used for solving the problems tha
