Abstract
The invention relates to the technical field of facial masks, and discloses a sandwich facial mask capable of producing hydrogen, generating heat and preserving heat, which aims at the problems that the sealing performance of the existing heating facial mask is higher due to the fact that a heating material reacts with air, and the heating material is exposed in the air and the heat is quickly dissipated, and comprises a surface base material layer, a water-permeable bottom surface base material layer and a hydrolysable hydrogen-producing material arranged between the surface base material layer and the bottom surface base material layer; the outer surface of the surface base material layer is also provided with a heat-insulating layer; the hydrolysable hydrogen production material is solid powder and comprises 10-90 parts by weight of at least one of sodium borohydride and metal hydride, 5-60 parts by weight of a neutralizing agent and 5-50 parts by weight of an adsorbing material. The sandwich facial mask disclosed by the invention can generate hydrogen production reaction after contacting with water, releases heat, is low in heat loss and high in storage stability in air, and the hydrogen production material is independently arranged between the bottom surface base material layer and the surface base material layer, so that other nutrient components can be prevented from being polluted and prevented from being polluted.
Description
Technical Field
The invention relates to the technical field of facial masks, in particular to a sandwich facial mask capable of producing hydrogen, heating and preserving heat.
Background
The mask on the market is mainly formed by tightly packaging mask cloth soaked in a large amount of nutrient solution at present. However, when the mask made of cold ice is used in cold seasons, pores of facial skin of a user can be shrunk, so that the purpose of absorbing nutrient solution cannot be achieved, and discomfort of the user can be increased.
Chinese patent CN201810358280.1, the patent name "spontaneous heating facial mask and its preparation method" discloses a spontaneous heating facial mask consisting of a nutrition layer, a heat conduction layer and a heating layer, wherein the heating layer faces to the air, and the heating purpose is achieved by utilizing the contact oxidation reaction of the heating active material of the heating layer and the air to generate heat. However, the heating mask requires that the heating layer needs to be stored in an air-isolated manner, and the vacuum sealing performance of the mask is relatively high; and the heating layer is exposed in the air, so that the heat loss is large. Meanwhile, the nutritional layer of the mask usually contains various essences including a moisturizing agent, an antioxidant, an anti-aging moisturizing agent, an anti-inflammatory agent and the like, and as the heating layer and the nutritional layer are integrated on one mask base material, nutritional ingredients, water and other liquid ingredients are easy to permeate into the heating layer, so that the heating active material is deteriorated and gradually loses activity, and the heating effect is reduced; meanwhile, active materials in the heating layer can pollute essence, easily cause skin allergy or other skin diseases, and bring bad experience to users.
The existing research shows that hydrogen can eliminate active free radicals and improve oxygen free radicals and energy metabolism level, so that the hydrogen has good improvement and control effects on various diseases in vivo, such as cardiovascular and cerebrovascular diseases, diabetes, high uric acid and the like. Meanwhile, hydrogen has small molecular volume, can easily enter cells such as cell nucleuses, mitochondria and other parts, has extremely strong penetrability, so the administration route is very wide, and the hydrogen can be directly taken into human bodies through breathing, drinking, skin and injection, and has wide medical hydrogen demand prospect. The hydrogen production mask in the market at present is mainly prepared by mixing hydrogen production materials into a paste and then coating the paste on the face, so that burning feeling can be generated on the face skin during use to cause skin irritation, and the hydrogen absorption efficiency is low.

Disclosure of Invention
Aiming at the problems that the sealing performance of the existing heating facial mask is higher due to the fact that a heating material reacts with air, and the heat of the heating material exposed in the air is rapidly dissipated, the invention aims to provide the sandwich facial mask capable of producing hydrogen, generating heat and preserving heat, which generates heat in the hydrogen production process, has good stability when placed in the air and high heat preservation performance.
The invention provides the following technical scheme:
a sandwich facial mask capable of producing hydrogen, generating heat and preserving heat comprises a surface base material layer, a water-permeable bottom base material layer and a hydrolysable hydrogen production material arranged between the surface base material layer and the bottom base material layer;
the outer surface of the surface base material layer is also provided with a heat-insulating layer;
the hydrolysable hydrogen production material is solid powder and comprises 10-90 parts by weight of at least one of sodium borohydride and metal hydride, 5-60 parts by weight of neutralizing agent and 5-50 parts by weight of adsorbing material.
Compared with the prior art, the facial mask is provided with the surface base material layer and the water-permeable bottom base material layer, the hydrolysable hydrogen production material is arranged between the surface base material layer and the bottom base material layer, the heat insulation layer is arranged on the outer side of the surface base material layer, the hydrolysable hydrogen production material can contact with water or alcohol to react to generate hydrogen and generate heat, and when the facial mask is used, one side of the bottom base material layer of the facial mask is wetted or the face is coated with water and then wetted to provide water required by the reaction. Therefore, the hydrolyzable hydrogen-producing material needs to react with water or alcohol, the stability of the mask in the air is improved, the sealing process requirement is reduced, the hydrolyzable hydrogen-producing material is positioned in the middle, the heat dissipation to the air is slow, the heat loss is low, and the heat loss of heat generated by the reaction of the hydrolyzable hydrogen-producing material is further reduced by the heat-insulating layer.
As the improvement of the invention, the metal hydride is at least one of calcium hydride, lithium hydride and sodium hydride with the grain diameter of 0.5-500 μm. The specific surface area of the powdered metal hydride contacted with water is large, and the efficiency of hydrogen production by hydrolysis can be improved.
As the improvement of the invention, the neutralizing agent is at least one of citric acid, oxalic acid and phosphoric acid solid powder with the grain diameter of 1-500 mu m; the adsorbing material is at least one of diatomite with the particle size of 1-500 mu m, a molecular sieve, zeolite, active carbon and foamy carbon solid powder. Citric acid and the like can neutralize alkaline substances generated by the reaction of metal hydride or sodium borohydride, maintain the neutral environment of the mask and reduce the reaction irritation of the mask. The adsorbent material provides reaction sites and can adsorb and remove the smell in the hydrogen gas.
As a modification of the invention, the hydrolyzable hydrogen production material also comprises 2 to 5 parts of hydrophilic fumed silica with the particle size of 20 to 100 nm. The hydrophilic nano silicon dioxide has extremely strong hydrophilic performance, can assist water capture, enhances the water capture and wetting capacity of the hydrolysable hydrogen production material, and improves the reaction efficiency. Meanwhile, the hydroxyl on the surface of the hydrophilic nano silicon dioxide has low activity and is not enough to react with sodium borohydride or metal hydride, so that the stability of the hydrolyzable hydrogen production material is ensured.
As an improvement of the invention, the metal hydride or the sodium borohydride is used after being treated by the following processes: adding hydrophilic fumed silica with the particle size of 20-100 nm into an acetone solution with the concentration of 10-40 g/L of polyethylene glycol to uniformly disperse, wherein the dispersion concentration is 10-25 g/L, then dispersing metal hydride or sodium borohydride into the acetone solution with the dispersion concentration of 50-450 g/L, standing, evaporating, dissolving, drying and crushing to obtain the treated metal hydride or sodium borohydride. The hydroxyl contained in the polyethylene glycol has low reaction activity and cannot react with sodium borohydride or metal hydride, but the polyethylene glycol has good hydrophilic performance and is beneficial to enhancing the water capturing capacity of the hydrolysable hydrogen production material. The inventor finds that the stability of the hydrolyzable hydrogen production material treated by the process is obviously enhanced within a period of time, probably because the polyethylene glycol has a long-chain structure and is fully dissolved in acetone, the long-chain structure of the polyethylene glycol is wound with the hydrophilic nano-silica and the hydrogen-containing compound and generates a synergistic effect with the three-dimensional network structure of the hydrophilic nano-silica, so that the bonding strength of the hydrophilic fumed silica and the metal hydride or the sodium borohydride is improved, and meanwhile, the effects of water accumulation and water accumulation (lake formation) are achieved in the presence of a large amount of water, and the hydrogen production reaction is promoted; in a dry air environment, the metal hydride or the sodium borohydride and the hydrophilic nano silicon dioxide jointly play a role in water binding, and the contact reaction of the metal hydride or the sodium borohydride and water is prevented. However, as the standing time is increased, water accumulation and water accumulation are increased, and when water absorption reaches a certain degree, the contact chance of the metal hydride or sodium borohydride and water is increased, so that the stability is reduced after the proper standing time is exceeded, and the hydrogen production effect is reduced.
As the improvement of the invention, the surface substrate layer is one of non-woven fabric, plastic film and cotton cloth; the bottom surface base material layer is one of a non-woven fabric, a cotton cloth and a permeable film with water permeability; the heat-insulating layer is made by coating aluminum powder or silver powder on the outer side surface of the surface substrate layer. The heat-insulating layer is made of aluminum powder or silver powder, cannot be consumed along with reaction, and is stable in heat-insulating capacity.
As the improvement of the invention, the bottom surface substrate layer and the surface substrate layer are correspondingly jointed at the outer edge, the edge of the eye hole, the edge of the nose hole and the edge of the mouth hole respectively; the bottom surface base material layer and the surface base material layer are uniformly distributed with a plurality of joints at respective non-edges; and the mutually corresponding joint of the bottom surface base material layer and the surface base material layer is pressed to form a pattern consisting of pressing lines and/or pressing surfaces.
A method for preparing the sandwich facial mask comprises the following steps:

The use of sandwich masks containing the hydrolyzable hydrogen-producing material of the above example was tested.
The method of the sandwich mask containing the hydrolysable hydrogen-producing material of the above example is as follows:
(1) A layer of water is uniformly sprayed on the outer side of the bottom surface base material layer of the sandwich facial mask,
(2) Attaching the outer side surface of the bottom surface base material layer of the sandwich facial mask sprayed with water to the face;
(3) And (4) keeping the sandwich facial mask for 10-15 minutes, then taking off the sandwich facial mask, and washing the face with clear water.

(II) Effect of use
The sandwich mask containing the hydrolysable hydrogen-producing material of the above example was used in 55 female volunteer testers aged 28-33 years according to the above water spray application method, and was randomly divided into 11 groups, and the anti-wrinkle efficacy was evaluated after continuous use for 4 weeks, 6 weeks, and 8 weeks, and evaluated for one week, three weeks, and six weeks, in combination with canthus wrinkle visualization and photo display. Another random search was conducted for 5 female testers of the same condition as a control group using a mask pack without a layer of hydrolyzable hydrogen-producing material. The judgment basis of the smoothness of the fine lines of the skin is divided into 7 grades, which are respectively as follows: 0, no wrinkles; 1 slightly less visible shallow wrinkles; 2 slightly visible and noticeable shallow wrinkles; 3 obvious shallow wrinkles can be seen; 4 slightly visible and distinct shallow wrinkles with slightly deeper wrinkles; 5, slightly deep wrinkles can be seen; 6 visible and obvious deep wrinkles; very pronounced deep wrinkles were visible 7. The testers of both the experimental group and the control group were in grade 5 status before the experiment. The verification test was conducted to observe that the smoothness of fine lines of the user could be reduced by several grades after using the mask of the above examples and the control mask for a period of time, and generally, the more the grade was reduced, the better. The results are shown in Table 1.
As can be seen from the table below, a 1-grade reduction in fine grain smoothness was achieved substantially after 4 weeks of use, but with continued use for 6 weeks or more, the mask of the present invention achieved a 2-grade reduction in fine grain smoothness of even greater effectiveness, whereas the conventional water mask did not remain much reduced. The inventor believes that this should be the control group absorbing much more water floating on the skin surface and really absorbing very little; due to the effects of heating and hydrogen production, the mask disclosed by the invention can enable the skin to absorb more water and nutrients, and can further improve the reduction of the smoothness of fine lines of the skin.
