Abstract
The present invention discloses a handling method of a non-thermoplastic soft foaming shoe midsole, which aims to enable the non-thermoplastic soft foaming shoe midsole (with the C-type surface hardness of less than 40) to contain no water and to maintain the original softness of shoe material and surfaces suitable for various grain structures and surface spraying; by utilizing non thermoplastic soft foaming products, the present invention comprises: first, constructing a base film in a mould in the molding process, and putting shaping elements in case of deformation in subsequent processing; then, carrying out foam molding; finally spraying, soaking and coating various colors or printing patterns on the base film.
Description
Technical field
The present invention relates to the processing method at the end in the flexible foamed footwear of a kind of non-thermal plasticity, belong to the sole manufacture field.
Background technology
The non-thermal plasticity soft foamed material has water imbibition or surface irregularity and difficult spraying, especially in footwear market, non-thermal plasticity soft foamed material soft originally, light specific gravity is the good material of correlated activation waterborne, but because of the microporosity of the flexible foamed product of non-thermal plasticity causes easy suction, and wear also uncomfortable, or micro porous out-of-flatness causes rough beautifully, makes a lot of producers abandon this soft on-deformable good material.
The processing method of non-thermal plasticity foaming body is to utilize rubber to make at foam-in-mould at present, promptly be attached in advance on the single surface mold and aftershaping, but may change the hardness or the water proofing property of product like this, more uncontrollablely be, the spray of foaming product under high adhesion force requires, be coated with, soak, all deformation problems can take place in the brush process, even adopt the heat shrink films mode to do surface coating, but because of no adhesive effect can not be combined into one with foaming body, so do not accepted by market.
Summary of the invention
The processing method that the purpose of this invention is to provide the end in the flexible foamed footwear of a kind of non-thermal plasticity, the microporosity that it can overcome the footwear material makes the visual level and smooth and free of pinholes phenomenon of basal surface in the footwear, and product (the C-TYPE case hardness is below 40) energy waterproof, and the surface is fit to various texture structure and external appearance spray finishing.
As shown in Figure 1, the end, be meant that sole is stepped on the position of touching in the footwear construction in the footwear, base film layer is to have elasticity and change the glued membrane that case hardness is no more than 5 degree, this glued membrane can be the diaphragm of moulding before producing, it also can be the glue of not moulding, can reach the function the same after being sprayed in the mould, construction base film layer and to control deformation be technology of the present invention place with the diaphragm of moulding.Concrete execution scheme is as follows:
In process of production, elder generation is at mould inside surface coating one base film layer, and the typing element can be put before the encapsulating foaming or after the foaming; According to footwear type needs, this typing element can be used in the reinforcement in the shoemaking flow process originally base plate and paste on base film layer or insert the iron wire analog, removes after waiting moulding.
The non-thermal plasticity foaming body divides outer foaming of mould and foam-in-mould method.Be illustrated in figure 2 as the outer foaming of mould: glue is latex (LATEX) foam, base film layer is affixed in the mould encapsulating moulding more earlier; Be illustrated in figure 3 as the foam-in-mould method: glue is polyurethane (POLYURETHANE) class, and base film layer can place Mo Nei in advance or abundant glue amount is injected at mould in the back of taking measurements in advance, can be in the foam-in-mould process abundant expansion molding, as shown in Figure 4.
After base film layer is coated on the foaming body periphery, can spray brushing shades of colour or print stamps at its skin, reach aesthetic effect, and skin sprays and still can have elasticity after the brushing and do not peel off.

The specific embodiment
The concrete execution scheme of coating base film layer and typing is as follows:
In process of production, elder generation is at mould inside surface coating base film layer, and the typing element can be put before the encapsulating foaming or after the foaming, so finished size can be controlled in advance; According to footwear type needs, the typing element can be used in the reinforcement in the shoemaking flow process originally base plate and paste on base film layer or insert the iron wire analog, removes after waiting moulding.
The non-thermal plasticity foaming body divides outer foaming of mould and foam-in-mould method.
Be illustrated in figure 2 as the outer foaming of mould: glue is latex (LATEX) foam, base film layer is affixed in the mould encapsulating moulding more earlier.
Be illustrated in figure 3 as the foam-in-mould method: glue is polyurethane (POLYURETHANE) class, and base film layer can place Mo Nei in advance or abundant glue amount is injected at mould in the back of taking measurements in advance, can be in the foam-in-mould process abundant expansion molding, as shown in Figure 4.After base film layer is coated on the foaming body periphery, can spray or print its outer selection, reach aesthetic effect.
