Abstract

The invention discloses a special sizing material for a foaming rubber sole, which utilizes natural rubber, a physical foaming agent and various compounding agents to be effectively matched to produce the sizing material for producing a foaming sole by an upper-joint glue injection process, so that the error of expansion ratios of different parts of a de-molded sole is obviously reduced, the appearance quality of the foaming sole is improved, and the sole qualified rate and the appearance grade are improved; and the sizing material produced by the invention is used when the foaming rubber sole is machined, so that the problems that the size stability of the foaming rubber sole is not good when a shoe is produced by using the upper-joint glue injection process and the appearance is rough are solved. The special sizing material is applicable to preparing the foaming soles of shoes including fashion shoes, winter heat-preservation shoes and the like.

Description

technical field

[0001] The invention belongs to the technical field of shoemaking, and in particular relates to a rubber material specially used for foaming rubber soles. Background technique

[0002] At present, the foamed rubber soles basically use a chemical foaming agent to cooperate with the corresponding foaming aids, and decompose at a suitable temperature to generate gas, form cells inside the rubber, and finally produce foamed rubber soles. Before the introduction of continuous side glue injection vulcanization process, rubber foam soles were produced through flat vulcanization process. After the foam soles were released from the mold, they were modified in appearance and then used in shoe production. In the production of continuous side glue injection vulcanization process, the following problems mainly exist in the production of rubber foam soles:

[0003] (1) The produced sole has a very irregular shape: the foamed rubber is constrained by the mold cavity in the...
