Abstract
The invention provides a toe box and heel cap material for shoes and a method of manufacturing the toe box and heel cap material for shoes. The toe box and heel cap material for shoes comprises a sandwich layer and a surface layer wrapping the same, wherein the sandwich layer is made of 100 parts of polyurethane, 60 parts of low-temperature polyester, 5 parts of triethylene diamine, 3 parts of stannous octoate, 5 parts of 1,4-Butanediol, and 6 parts of trimethylolpropane, and the surface layer is made of 100 parts of hot melt glue level polyurethane and 30 parts of thermoplastic elastomer. The hardness and strength of the toe box and heel cap material for shoes are improved further, the toe box and heel cap material is easy to trim and excellent in bending resistance, the toe box and heel cap material is active at low temperature and free of glue overflow, opening time is shortened so that the material can be shaped quickly, and the toe box and heel cap material has high bonding power. Leftover obtained by trimming the material can be recycled and reused. By the method of manufacturing the toe box and heel cap material for shoes, manufacturing procedures are simplified for enterprises, operation is facilitated for shoe makers, and production efficiency and labor intensity are reduced for the shoe makers.
Description
Technical field
The present invention relates to a kind of interior material for increasing shoes intensity and hardness of shoes that is placed on, more specifically refer to heel and toe stiffener material and manufacture method thereof for a kind of footwear.
Background technology
The heel and toe stiffener of shoes is the reinforcing devices for toe-cap and heel inside, they be placed on the inner surface of shoes and inside between, object is to keep the profile of shoes, and increases intensity and the hardness of shoes.What shoemaking circle at present generally adopted is solvent-borne type chemistry sheet or heat setting film for making the heel and toe stiffener material of shoes, in the concrete process of using, need long time sizing, and due to the restriction of material, shoemaking personnel are in the process of manufacturing, need too much operation, not only strengthen shoemaking personnel's labour intensity, be also unfavorable for improving the production efficiency of enterprise.
Summary of the invention
Main purpose of the present invention is to provide a kind of footwear heel and toe stiffener material, it further promotes footwear by hardness, the intensity of heel and toe stiffener material, and chamfered edge is easy, and resistance to tortuous performance is fabulous, make footwear material low-temperature activation, excessive glue, shorten open hour fast shaping, there is very strong cohesive force.The recyclable recycling of leftover pieces after cutting.
Another object of the present invention is to provide the manufacture method of a kind of footwear with heel and toe stiffener material, and it simplifies the operation of enterprise in manufacturing process, facilitates shoemaking personnel's operation, improves its production efficiency and reduces its labour intensity.
The technical solution used in the present invention is: a kind of footwear heel and toe stiffener material, it comprises sandwich of layers and the top layer that this sandwich of layers is wrapped up, wherein, this sandwich of layers by the polyurethane of 100 parts, 60 parts low temperature polyester, 5 parts triethylenediamine, 3 parts stannous octoate, 5 parts 1,4-bis-butanols, the trimethylolpropane of 6 parts form, and to be the PUR level polyurethane of 100 parts, 30 parts of thermoplastic elastomers form on this top layer.
The manufacture method of heel and toe stiffener material for a kind of footwear, comprise: step 1, make sandwich of layers, the polyurethane of 100 parts is mixed with the low temperature polyester of 60 parts, then add 5 parts triethylenediamine, 3 parts stannous octoate, 5 parts 1,4-bis-butanols, the trimethylolpropane of 6 parts, mix by by extruding after an extruder melting;
Step 2, makes top layer, after sandwich of layers as above is extruded after extruder melting, at the PUR level polyurethane of 100 parts of its surface coverage and the mixture of 30 parts of thermoplastic elastomers.
Step 3, the material of step 1 and step 2 melt extrudes through major-minor extruder, by certain speed ratio, is rolled into certain thickness even sheet material.
Beneficial effect of the present invention is: the present invention further promotes footwear by hardness, the intensity of heel and toe stiffener material, and chamfered edge is easy, and resistance to tortuous performance is fabulous, and footwear material can low-temperature activation, the glue that do not overflow, shorten open hour fast shaping, has very strong cohesive force.The recyclable recycling of leftover pieces after cutting.
It simplifies the operation of enterprise in manufacturing process the present invention, facilitates shoemaking personnel's operation, improves its production efficiency and reduces its labour intensity.
The specific embodiment
A kind of footwear heel and toe stiffener material, it comprises sandwich of layers and the top layer that this sandwich of layers is wrapped up, wherein, this sandwich of layers by the polyurethane of 100 parts, 60 parts low temperature polyester, 5 parts triethylenediamine, 3 parts stannous octoate, 5 parts 1,4-bis-butanols, the trimethylolpropane of 6 parts form, and to be the PUR level polyurethane of 100 parts, 30 parts of thermoplastic elastomers form on this top layer.
These footwear are included as by the manufacture method of heel and toe stiffener material:
Step 1, make sandwich of layers, the polyurethane of 100 parts mixed with the low temperature polyester of 60 parts, then add 5 parts triethylenediamine, 3 parts stannous octoate, 5 parts 1,4-bis-butanols, the trimethylolpropane of 6 parts, mix by by extruding after an extruder melting;
Step 2, makes top layer, after sandwich of layers as above is extruded after extruder melting, at the PUR level polyurethane of 100 parts of its surface coverage and the mixture of 30 parts of thermoplastic elastomers.
Step 3, the material of step 1 and step 2 melt extrudes through major-minor extruder, by certain speed ratio, is rolled into certain thickness even sheet material.
Footwear of the present invention are cut into after required type body with heel and toe stiffener material, after sewing up in shoes, need in hot-die vapor (steam) temperature, be 120～130 ℃ by the present invention, activate 15～20 seconds (temperature and time need be adjusted according to facial material and the variation of material inside); After having toasted, enter immediately cold forming tightening type, in 0～4 ℃, keep 15～20 seconds, can make shoes there is profile attractive in appearance, can play good protection and supporting role.
