Labor protection glove and production method thereof

Abstract

A labor protection glove includes a glove body including a glove liner and a back rubber protection layer disposed on a surface of a back of the glove liner. The glove liner includes a skin contact layer, a moisture absorption layer disposed outside the skin contact layer and a wear-resistant layer disposed outside the moisture absorption layer. The back rubber protection layer includes a finger rubber layer disposed at a back of a finger of the glove, a palm-back rubber layer disposed at a back of a palm of the glove body, and a root knuckle rubber layer disposed between the finger rubber layer and the palm-back rubber layer for protecting a knuckle. The finger rubber layer and the root knuckle rubber layer are independently formed by injection molding.

What is claimed is: 
     
         1 . A labor protection glove, comprising a glove body, wherein the glove body comprises a glove liner and a back rubber protection layer disposed on a surface of a back of the glove liner, the glove liner comprises a skin contact layer, a moisture absorption layer disposed outside the skin contact layer and a wear-resistant layer disposed outside the moisture absorption layer, the back rubber protection layer comprises a finger rubber layer disposed at a back of a finger of the glove, a palm-back rubber layer disposed at a back of a palm of the glove body, a root knuckle rubber layer disposed between the finger rubber layer and the palm-back rubber layer for protecting a root knuckle, and the finger rubber layer and the root knuckle rubber layer are independently formed by injection molding. 
     
     
         2 . The labor protection glove according to  claim 1 , wherein a plurality of grooves are disposed at a surface of the finger rubber layer. 
     
     
         3 . The labor protection glove according to  claim 1 , wherein a plurality of arc-shaped recesses are disposed at one side of the root knuckle rubber layer close to the finger rubber layer with openings of all the arc-shaped recesses facing the finger rubber layer. 
     
     
         4 . The labor protection glove according to  claim 3 , wherein a connection rubber layer is disposed at one side of the root knuckle rubber layer away from the finger rubber layer, and the connection rubber layer is integrally connected with the root knuckle rubber layer and the palm-back rubber layer by injection molding. 
     
     
         5 . The labor protection glove according to  claim 4 , wherein a pair of groove-shaped openings symmetrical with respect to the connection rubber layer are disposed between the root knuckle rubber layer and the palm-back rubber layer. 
     
     
         6 . The labor protection glove according to  claim 3 , wherein a first division groove is disposed at one side of the arc-shaped recesses of the root knuckle rubber layer close to the palm-back rubber layer. 
     
     
         7 . The labor protection glove according to  claim 1 , wherein a surface of the palm-back rubber layer is provided with a second division groove including a plurality of transversal division grooves and longitudinal division grooves which cross each other. 
     
     
         8 . The labor protection glove according to  claim 1 , wherein a wear-resistant rubber layer is disposed at one side of a palm of the glove body. 
     
     
         9 . A production method of the labor protection glove according to  claim 1 , the production method comprising the following steps:
 step 1, preparing the glove liner: weaving the skin contact layer and the moisture absorption layer to form the glove liner;   step 2, sewing the wear-resistant layer: sewing the wear-resistant layer on an outer surface of the glove liner; and   step 3, preparing the back rubber protection layer: wearing the glove liner on a hand model, placing the hand model with the glove liner into a rubber-injecting mould of an integrated injection molding machine, closing the rubber-injecting mould, injecting rubber onto an upper surface of the finger of the glove via a rubber-injecting hole located above the finger of the glove while injecting molten rubber into a rubber-injecting hole located at the root knuckle, and cooling to integrally form the root knuckle rubber layer and the palm-back rubber layer, so as to obtain the back rubber protection layer by rubber injection, wherein a rubber-injecting temperature is in a range of 180-220° C., and a rubber-injecting pressure is in a range of 15-22 MPa.   
     
     
         10 . The production method of the labor protection glove according to  claim 9 , wherein the molten rubber in the step 3 is one selected from a group consisting of TPE, TPR and TPU.
