Abstract
The invention relates to the technical field of shoe materials and manufacturing methods, in particular to a tough PU thin film-coated shoe material and a manufacturing method thereof. The shoe material comprises a tough PU thin film layer and a shoe material body, wherein the tough PU thin film layer is coated at the bottom and the periphery of the shoe material body and is a colored layer or a transparent layer, and the surface of the tough PU thin film layer has textures and patterns. The manufacturing method of the shoe material comprises the following steps of: laying a thin film layer of a PU material in a lower mould for manufacturing the shoe material; heating the mould for manufacturing the shoe material at the temperature of 50-150 DEG C for 2-15 seconds so that the tough PU thin film layer is softened and laid on the inner surface of the cavity of the mould; injecting the liquid-state PU material into the mould so that the shoe material is formed in the mould, wherein the PU material is sufficiently jointed with the tough PU thin film layer so as to be integrally formed; and opening the mould, taking the mould out and clearing up scraps. The formed shoe material has smoothness, a good aesthetic effect and low production cost.
Description
Technical field:
The present invention relates to footwear material technical field and preparation method, refer in particular to a kind of footwear material and preparation method of utilizing toughness PU film to coat.
Background technology:
In shoe-making field, the processing method of sole footwear material is as follows: spray mould release earlier in the die cavity of mould; In mould, inject PU (polyurethanes is called for short polyurethane) material again, make the footwear material at in-mold molding; Take out the footwear material of moulding at last and repair, as the tonifying Qi bubble and the mouth of filling a vacancy, the pit on polishing footwear material surface, but also must be through repeatedly carrying out the light face footwear materials such as just can making the different big end of moulding and decorative pattern, the middle end that sprays paint.
There is following subject matter in its processing method: need vacuumize and mould that needs are special, production cost is very high; Form easily bubble, breach, pit on the PU sole, and unevenly wait the defective that influence is attractive in appearance and use, must drop into great amount of manpower and carry out methods such as repeatedly light face sprays paint and repaired the easy flavescence of color after spraying paint; Simultaneously also can produce a large amount of defective products, cause the waste of material and human cost.
Also have, avoid waterproof and hydrolysis, must adopt polyether material in a large number, this material is not easy hydrolysis, easily environment is polluted after discarded, is unfavorable for protecting environment.
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, and a kind of footwear material and preparation method of utilizing toughness PU film to coat is provided, the sliding aesthetic feeling of the bright sensitization of moulding footwear material is good, and production cost is low.
For achieving the above object, the present invention adopts following technical scheme: it comprises toughness PU thin layer, footwear material body, and toughness PU thin layer is coated on the bottom and the periphery of footwear material body.
Described toughness PU thin layer is painted or transparent any one, and its surface has decorative pattern, pattern.
The preparation method of footwear material may further comprise the steps:
(1), at the film of counterdie upper berth one deck PU material of making the footwear material;
(2), carry out 50 ℃-150 ℃ and heat, 2-15 second, make toughness PU thin layer softening and apply in the surface of die cavity to making the footwear timber die;
(3), in mould, inject the PU material of liquid, make the footwear material at in-mold molding, the PU material fully engages with toughness PU thin layer, is shaped to one;
(4), open mould, taking-up footwear material, arrangement rim charge.
Beneficial effect of the present invention is: the present invention adopts the PU film to carry out 50 ℃-150 ℃ and heats, 2-15 second, make toughness PU thin layer softening and apply in the surface of die cavity, liquid PU material is combined as a whole with the PU film in die cavity, can avoid generation of defects such as bubble, breach, pit, has strengthened the smooth aesthetic feeling of moulding footwear materials, the floral designs molding effect is clearly demarcated, outward appearance does not need to spray paint, and, easier and mold separation; The PU film also can strengthen the anti-hydrolysis performance of footwear material in addition.

The specific embodiment:
See that Fig. 1 is to shown in Figure 7: the present invention adopts following technical scheme: it comprises toughness PU thin layer 1, footwear material body 2, and toughness PU thin layer 1 is coated on the bottom and the periphery of footwear material body 2.
Described toughness PU thin layer 1 is painted or transparent any one, and its surface has decorative pattern, pattern.
The preparation method of footwear material may further comprise the steps:
(1), the film 1 in counterdie upper berth one deck PU material of making the footwear material, and thin layer 1 is fixed on the upper surface of counterdie A with the fixing hole C on the counterdie A;
(2), the footwear timber die is moved on to the high temperature furnace 3 times (also can use stove) of illumination, high temperature furnace 3 uses electrically heated mode, the footwear timber die is carried out 50 ℃-150 ℃ heat, 2-15 second, make toughness PU thin layer 1 softening and apply in the surface of die cavity, as shown in Figure 4;
(3), injector 4 injects the PU material of liquid in mould, allow counterdie A and patrix B close, and as shown in Figure 6, makes the footwear material at in-mold molding, the PU material fully engages with toughness PU thin layer 1, is shaped to one;
(4), open mould, take out the footwear material, the arrangement rim charge, as shown in Figure 7.
The shiny surface of described toughness PU thin layer 1 contacts with the inwall of counterdie die cavity, is convenient to the demoulding, and toughness PU thin layer 1 is an one with described liquid PU forming materials.Like this, on the one hand toughness PU thin layer 1 is combined better with liquid PU material, can realize combination more closely and can not produce bubble;
Do not need to vacuumize, also do not need special mould, production cost reduces greatly; Carry out 50 ℃-150 ℃ and heat making the footwear timber die, 2-15 second, make toughness PU thin layer 1 softening and apply in the surface of die cavity; Solved on the sole and to have formed bubble, breach, pit easily, and unevenly waited the defective that influence is attractive in appearance and use, made its surface more smooth, opened mould, take out the footwear material after, only need be to the footwear rim leftover, removing is repaired and is got final product.
The above only is preferred embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
