Method of manufacturing shoe insoles and shoe insole

Abstract

A method of manufacturing shoe insoles, comprises steps of: step 1, making a resin mixture by mixing a resin and a hardening agent in a container; step 2, impregnating a glass fiber cloth with the resin mixture in step 1; step 3, cutting the glass fiber cloth impregnated in step 2 according to a pre-determined shape of a half insole or of an insole; step 4, hot-press forming a product by adding the glass fiber cloth cut in step 3 to a pre-heated mold, and heat pressing the glass fiber cloth to obtain the product of a shoe insole. A shoe insole manufactured according to the above method and a shoe comprising the same are also disclosed, involving high strengths, small thicknesses, light weights, resistances to moisture as well as hydrolysis, longtime molding effects, a strong weatherability and a good balance, and facilitating the standardization of shoe manufacturing.

1 . A method of manufacturing shoe insoles, wherein, the method comprises steps as follows:
 step 1, stirring a resin mixture, wherein, the resin mixture includes resin, 0.1%-80% of hardening agent, 1%-30% of low shrinkage agent, 0.5%-10% of thickening agent and 0.5%-10% of releasing agent, the resin is any of unsaturated resin, epoxy resin, vinyl resin and phenolic resin, and the resin is stirred to mixed with the hardening agent, low shrinkage agent, thickening agent and releasing agent in a container;   step 2, impregnating a glass fiber cloth by saturating the glass fiber cloth with the resin mixture stirred in step 1;   step 3, trimming the glass fiber cloth by cutting the glass fiber cloth impregnated in step 2 according to a pre-determined shape of a half insole or of an insole;   step 4, hot-press forming a product by adding the glass fiber cloth cut in step 3 to a pre-heated mold, and heat pressing the glass fiber cloth cut in step 3 to obtain the product of a shoe insole.   
     
     
         2 . The method of manufacturing shoe insoles according to  claim 1 , wherein, the method also includes step 5, burrs removing; via a rubbing device to remove burrs. 
     
     
         3 . The method of manufacturing shoe insoles according to  claim 1 , wherein, the glass fiber cloth of step 2 includes any of glass fiber cloth woven roving, single direction glass fiber cloth, twill glass fiber cloth, and tricot-knitted glass fiber cloth. 
     
     
         4 . The method of manufacturing shoe insoles according to  claim 1 , wherein, the glass fiber cloth of step 2 is glass fiber cloth woven roving with a areal density of 200 g/m2-1200 g/m2. 
     
     
         5 . The method of manufacturing shoe insoles according to  claim 1 , wherein, the glass fiber cloth of step 3 has a multilayered composite structure. 
     
     
         6 . The method of manufacturing shoe insoles according to  claim 1 , wherein, the mold of step 4 is provided with a pre-heating temperature of 100-108° C., a heating pressure of 10-180 kg/cm2, and a heat pressing time of 80-240 s, and in step 4, the glass fiber cloth cut in step 3 and a soft midsole are heat pressed. 
     
     
         7 . A shoe insole, wherein, the shoe insole is manufactured according to  claim 1 , the shoe, insole includes a soft midsole and a glass fiber layer-on-layer molded midsole configured on a upper side of the soft midsole, and herein the glass fiber layer-on-layer molded midsole is manufactured through heat pressing a plurality layers of glass fiber cloth impregnated by the resin mixture. 
     
     
         8 . A method of manufacturing shoe insoles, wherein the method comprises steps of:
 step  1 , stirring a resin mixture, wherein, the resin mixture includes materials of resin which is any of unsaturated resin, epoxy resin, vinyl resin and phenolic resin, and also includes 0.1%-80% of hardening agent, 1%-30% of low shrinkage agent, 0.%-10% of thickening agent and 0.5%-10% of releasing agent; and all the materials are stirred to mixed together in a container;   step 2, impregnating a glass fiber cloth by saturating the glass fiber cloth with the resin mixture already stirred in step 1;   step 3, trimming the glass fiber cloth already impregnated in step 2 according to a pre-determined shape of a half insole or of an insole cleaving a back part of a paperboard or of a cloth board, and sandwiching the already cut glass fiber cloth into the cleaved paperboard or into cloth board;   step 4, hot-press forming a product by adding the paperboard or the cloth board of step 3 into a pre-heated mold, which is provided with a pre-heating temperature of 100-108° C.; a heating pressure of 10-180 kg/cm2, and a heat pressing time of 80-240 s;   step 5, burrs removing, via a rubbing device to remove burrs so as to obtain a product of the shoe insole;   and herein, the glass fiber cloth of step 2 includes any of glass fiber cloth woven roving, single direction glass fiber cloth, twill glass fiber cloth, and tricot-knitted glass fiber cloth.   
     
     
         9 . A shoe insole, wherein, the shoe insole comprises a paperboard or a cloth board, and the shoe insole is obtained in such a way that: except afore part of the paperboard, the paperboard or the cloth board is cleaved at a back part, the rest part of the paperboard, is cleaved; a lass fiber cloth which has been impregnated with a resin mixture, is inserted into the cleaved back part; and finally a process of heat pressing is carried out. 
     
     
         10 . A shoe insole, wherein, the shoe insole comprises two pieces of cloth, a fore portion of the two pieces of cloth is bonded together, a glass fiber cloth impregnated by resin mixture is inserted into and sandwiched between un-bounded part of the two pieces of cloth, and the shoe insole is obtained by heat pressing the two pieces of cloth and the a glass fiber cloth.
