Description

Novel self-heating eye patch and preparation process thereof

Technical Field

The invention relates to the technical field of eye shield manufacturing, in particular to a novel self-heating eye shield and a preparation process thereof.

Background

With the advancement of science and technology and the acceleration of life rhythm, people often need to face computers or read data for a long time and use eyes in close range for a long time, so that ciliary muscles are in a contraction state for a long time, continuous congestion, increased intraocular pressure and eye fatigue in eyes are caused, the problems of dry eyes, heavy eyelids, eye socket pain, double shadows and the like are caused, and symptoms such as dizziness, headache, nausea and the like are caused seriously. In addition, with the pressure from work, academic and life increasing, many people are in an insomnia state, and the eyes are lack of water due to local blood supply difficulty caused by insufficient sleep.

In order to solve the problems, a series of steam eye mask products appear on the market in recent years, which care the eyes by a self-heating principle, wherein a heating body arranged in the eye mask reacts with oxygen in the air to generate heat, water in the heating body is evaporated to form water vapor, and the blood circulation and cell activity around the eyes can be accelerated, so that the effects of relieving eye fatigue, moistening the eyes, enhancing the blood circulation of the eyes, removing black eyes and eye bags and the like are achieved. The vapor eye mask originally originated in japan, and the lightweight, environmentally friendly eye protection product quickly received the popularity of consumers.

To enable longer and more constant temperatures, steam eye mask products use very precise oxygen permeable bags. The bag material is particularly desirable because the product does not react until use, and is typically formed from a composite of multiple layers. When in use, the outer bag is removed, and after the product is exposed in the air for 30 seconds, oxygen in the air enters the inner bag through the micro oxygen permeable bag. The time and temperature of the released heat are controlled by the oxygen transmission rate of the oxygen transmission bag. If the oxygen permeation is too fast, the heat generated along with the oxygen permeation is too much, and the skin is possibly scalded; if the oxygen permeation is too slow, the temperature is too low. The heating element in the steam eye shield is black brown solid after use, and contains ferric oxide, carbon powder, etc.

The heating sheet of the existing eye patch comprises tablets and powder, the heating time of the tablets is short, and the heating time of the powder is long but the powder has the problem of heating and falling.
