Mask

Abstract

The creation provides a mask having the function of heat preservation. The mask includes an outer layer, an inner layer, and an intermediate layer. The inner layer is in contact with the user's face. The intermediate layer is located between the outer layer and the inner layer. The intermediate layer contains a base layer and a coating layer located on the base layer. The coating layer includes a paraffin particle and a first polymer, wherein the paraffin particle is dispersed in the first polymer.

What is claimed is: 
     
         1 . A mask, comprising:
 an outer layer;   an inner layer in contact with a user's face; and   an intermediate layer located between the outer layer and the inner layer,   the intermediate layer contains a base layer and a coating layer located on the base layer, the coating layer comprises a paraffin particle and a first polymer, wherein the paraffin particle is dispersed in the first polymer.   
     
     
         2 . The mask of  claim 1 , wherein the coating layer is formed by applying a coating solution on the base layer and then drying, and the coating solution comprises the paraffin particle, the first polymer, and a solvent. 
     
     
         3 . The mask of  claim 2 , wherein a thickness of the coating layer is 10 μm to 30 μm. 
     
     
         4 . The mask of  claim 1 , wherein a diameter of the paraffin particle is 80 nm to 200 nm. 
     
     
         5 . The mask of  claim 1 , wherein the paraffin particle comprises a paraffin core portion and a cladding layer covering a surface of the paraffin core portion. 
     
     
         6 . The mask of  claim 5 , wherein the paraffin core portion is formed by a C 8  to C 30  hydrocarbon compound. 
     
     
         7 . The mask of  claim 5 , wherein the paraffin core portion comprises a straight-chain hydrocarbon compound, a branched-chain hydrocarbon compound, a cyclic hydrocarbon compound, or a combination thereof. 
     
     
         8 . The mask of  claim 1 , wherein the first polymer comprises polymethylmethacrylate, polyurethane, or a combination thereof. 
     
     
         9 . The mask of  claim 8 , wherein the polyurethane is aqueous polyurethane. 
     
     
         10 . The mask of  claim 1 , wherein based on a total amount of 100 wt % of the paraffin particle and the first polymer, a content of the paraffin particle is 20 wt % to 60 wt % and a content of the first polymer is 40 wt % to 80 wt %. 
     
     
         11 . The mask of  claim 1 , further comprising two straps, wherein the outer layer, the inner layer, and the intermediate layer form a mask body, and the two straps are respectively located at two sides of the mask body.
