Abstract

The invention discloses the method for preparation of polyurethanes shoe-pad with breather, comprising the following steps: preparing a forming die with cloth layer and boring unit, on the bottom of the cloth layer coating a isolated layer to form base material, fixing the base material on the bottom of the forming die, pouring polyurethanes into the bottom seat of the forming die, closing the forming die, making the boring unit pass the polyurethanes raw material and base material, after the exothermal reaction of polyurethanes raw material and base material, opening the forming die, getting the half-finished product, and cutting it and getting the product.

Description

technical field [0001] The invention relates to an insole made of polyurethane material, in particular to a method for manufacturing a polyurethane insole with air holes. Background technique [0002] like figure 1 Shown, there is a kind of manufacture method of the polyurethane insole with air vent, comprises the following steps: [0003] Step 1: Prepare a cloth layer and a forming mold, the forming mold has a lower mold base and an upper mold base corresponding to the lower mold base. [0004] Step 2: Coating an isolation layer such as viscose on the bottom surface of the cloth layer to form a base material. [0005] Step 3: Fix the base material on the bottom surface of the upper mold base, and pour the polyurethane raw material into the lower mold base of the forming mold. The polyurethane raw material is made of isocyanate, multi-component It is made by mixing two liquids such as alcohol. [0006] Step 4: Close the upper and lower mold bases of the forming mold, and...
