Method for manufacturing environmental protection insole

Abstract

A method for manufacturing insole uses used footwear and recycled wooden articles are primary ingredients, which are pulverized to form particles of the recycled materials. The recycled wood, taking a ratio of weight of 15-35%, is uniformly mixed with matrix rubber that functions to adjust physical properties and foaming agent, and then pressed to form an insole material in a sheet form, which is deposited in a mold to be heated and pressurized for curing and setting thereby forming an insole featuring proper resilience and anti-bacteria and deodorization. The use of the insole is thus completely sanitary and comfortable and also features pollution- and nuisance-free use by repeated use in the sense of environment conservation.

1 . A method for manufacturing insole, comprising mixing a raw material that is made of used footwear and matrix rubber to form a mixture and subjecting the mixture to depositing in a mold for shaping, curing and setting, and edge trimming, characterized in that used wooden material is pulverized to form particles and flakes having a size less than 5 mmf and mix, at a ratio of weight of 15-35%, with tiny particles that is formed by pulverizing the used footwear, which takes a ratio of 5-60%, and further added with the matrix rubber taking a ratio of 5-75%, and afterwards, deposited in a processing machine and further added with a predetermined amount of foaming agent, followed by uniformly stirring with the processing machine and subsequently subjected to sheeting, the sheet being then molded and shaped by being pressed by closing an insole mold and heated and pressurized inside the mold for curing and setting, whereby an insole having proper softness and flexibility and featuring anti-bacterial and deodorizing functions is obtained. 
     
     
         2 . The method according to  claim 1 , wherein in the step of mixing, fragrance is added, including a bamboo vinegar solution or essence oil that is added in a ratio of 1-2% to assist anti-bacteria and aromatic smell. 
     
     
         3 . The method according to  claim 1 , wherein the matrix rubber comprises a combination of natural rubber, artificial rubber, filler, additives, and process oil in predetermined ratios. 
     
     
         4 . The method according to  claim 1 , wherein a sheet obtained through the sheeting operation has a thickness of 1-50 mm. 
     
     
         5 . The method according to  claim 1 , wherein the foaming agent is added with a ratio of 1-2% of the mixed material.
