Abstract
The invention relates to a manufacturing method of a polyurethane inner sole and is characterized in that the manufacturing method comprises the following steps in sequence: materials are prepared: a component a and a component b are prepared and are respectively placed; a polyurethane film which meets the requirement is laid on the inner surface of a lower die body (22); an upper die body (21) is covered; an aspirating hole is used for vacuumizing so as to lead the polyurethane film to be adhered on the corresponding inner surface of the lower die body (22); the component a and the component b are mixed; the mixed mixture is injected into a die by a die filling port (24) till the mixture appears at a flash gate (25) of a die (2) and then stands for 2 to 30 minutes; and a polyurethane inner sole (1) with rough edges is taken out for carrying out trimming so as to obtain a finished product. The method has the advantages that the polyurethane surface of the back surface of the inner sole is a non-film surface; and the inner sole can be adhered with the bottom surface of shoes when in use, thus eliminating the problem that the change of the origin of force of the sole of a foot can cause the sliding of the inner sole easily when people walk.
Description
Technical field
The present invention relates to a kind of preparation method of polyurethane insole.
Background technology
The Chinese invention patent that existing a kind of application number is called " manufacturing approach of permeable shoe pads " for the CN200510008635.7 name has proposed a kind of preparation method of shoe-pad; This method is injected a foamed material in one die cavity of one bed die; Again with the closed die cavity of one first backform and heat, in die cavity, builds bridge, foam and constitute one polyurethanes/polyurethane body to touch foamed material, follow under the still uncolled state of this polyurethanes/polyurethane body; Open first backform; Utilize the closed die cavity of one second backform then, make the fibrous material and the adhesion material that are arranged on this second backform insert this die cavity in the lump, and control this second backform and be not less than under the melt temperature of this adhesion material one and heat; This adhesion material of fusion and produce caking property, finally demould just obtains a shoe-pad.The permeable shoe pads that uses this method to make has the advantage of gas permeability, strength of connection and good looking appearance preferably.But its shortcoming is, the shoe-pad that this method makes, and after shoe-pad placed on the sole face, when the people was stepping on shoe-pad and walks, because sole impetus conversion and shoe-pad is slided, it was very inconvenient to cause walking, also uncomfortable, so its method awaits to improve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of making to have the pure preparation method that ammonia does not have the shoe-pad of face of gathering to above-mentioned prior art present situation, makes the shoe-pad of processing be difficult in use sliding.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the preparation method of this polyurethane insole is characterized in that: in turn include the following steps:
One, batching: the raw material that can be made into polyurethane after preparation mixes;
Two, satisfactory polyurethane film on auxilliary pad on the lower mold body inner surface of mould, being evacuated and polyurethane film inhaled through aspirating hole is attached on the inner surface of die body;
Three, will prepare burden and inject mould through the mould inlet, to batching the flash mouth of mould appear as to, wait for 2～30 minutes;
Four, with moulds open, take out the polyurethane insole of band burr, carry out deburring, be finished product.
As improvement, said batching is selected to be made up of component a and components b, and the component a after will disposing and components b are placed respectively; Basic composition is of component a wherein: PPG 40～70%; PEPA 25～55%; Butanediol or/and ethylene glycol or/and the propane diols neopentyl glycol or/and hexylene glycol or/and diethylene glycol or/and DPG 0.1～5%, the inferior tin of octanol or/and dibutyl tin two laurate or/and isooctyl acid bismuth 0.09-1.5%; Basic composition is of components b wherein: PPG 30～60%; PEPA is or/and PCDL 5～30%; Isocyanates 0～60%, hexanedioyl chloride be or/and phosphoric acid or oleic acid 0.001～0.1%, butanediol or/and neopentyl glycol or/and hexylene glycol 0.3～5%; The mixing ratio component of component a and components b is 3:2～7:3, above-mentioned being weight percentage.
Improve again, in step 2, also include the upper die body that can be laminated with mutually with said lower mold body, and on this upper die body inner surface, be sprayed with releasing agent; Its preparation temperature of said component a and components b may be selected to be 0 ℃～80 ℃; And described component a and the components b component liquid temp when mixing may be selected to be 20 ℃～60 ℃.
Improve, the temperature of mould is chosen as 0 ℃～100 ℃ in step 2 and the step 3 again, and this mould can come heating mould through steam pipe or the electrothermal tube that is installed on the mould.
Improve, its deburring can be carried out deburring in the said step 4 on trimmer again, the polyurethane insole of band burr is positioned in the bottom trim mode of trimmer, again with the extruding downwards of top trim mode and with the burr excision of polyurethane insole.
Improve, its kind of said shoe-pad may be selected to be sole-shaped shoe-pad or heel shoe-pad again.
Compared with prior art; The invention has the advantages that satisfactory polyurethane film on auxilliary pad on the lower mold body inner surface of mould; Be evacuated and polyurethane film inhaled through aspirating hole and be attached on the inner surface of die body; The polyurethane surface of its reverse side of shoe-pad of processing like this is the pure ammonia face that gathers of no film, because the surface of its no film of character of polyurethane itself can produce certain viscosity, so work as shoe-pad in use; Shoe-pad just can stably stick on sole face, thereby has eliminated the problem that owing to the conversion of sole impetus shoe-pad is slided when the people walks.Also have, the cushion course structure of the shoe-pad of processing with this method, make the people step down on the shoe-pad vibrationproof better and soft feel comfortable, and intensity is good, it is also convenient to make.
