Description
Technical field
This utility model belongs to rubber soles field, specifically, relates to a kind of sheet rubber for being combined with polyurethane.
Background technology
At present, due to the raising day by day of people's living standard, shoes be not only one be through on foot be easy to our walking
Thing, people propose the newest requirement to shoes, such as fashionable appearance, slim and graceful, the anti-skid wearable of quality etc..Therefore, at footwear
In the design process at the end, can utilize the combination of material to improve the performance of sole, as by lighter to wear-resisting rubber and quality poly-
Urethane combines, and sole will have anti-skid wearable and the slim and graceful characteristic of quality.
In the technique that rubber is combined with polyurethane, it is necessary first to make the sheet rubber for being combined with polyurethane, so
After sheet rubber embedded polyurethane mould in be irrigated, ultimately form the integrative-structure of rubber and polyurethane.But, existing
Manufacturing process has following defects that 1, from theory, the sheet rubber that design produces should with the convex tendon on polyurethane mould
Fit like a glove, but in actual production process, owing to sheet rubber mould and polyurethane mould are not that same technique makes
, add mold temperature, the factor such as sheet rubber shrinks, sheet rubber releasing process and ambient temperature, all can cause sheet rubber with
There is gap between convex tendon on polyurethane mould, when carrying out Polyurethane Perfusion, polyurethane stock solution will be pierced by gap
Bottom sheet rubber, cause the generation of flash phenomena, so can increase the percent defective in production process；2, the edge of sheet rubber is perpendicular
Straight, so not only result in the generation of flash phenomena, increase percent defective, but also be easily caused the generation of phenomenon of coming unglued.
Summary of the invention
The purpose of this utility model is to provide a kind of sheet rubber for being combined with polyurethane, and its technique is simple, it is possible to
Effectively solve the flash phenomena during Polyurethane Perfusion, and be not easy to come unglued.
The technical scheme that this utility model is used by solving technical problem is as follows: a kind of rubber for being combined with polyurethane
Film, it mainly includes that patterned surface and rubber edge, described patterned surface are provided with decorative pattern, and described rubber edge is arranged on patterned surface
Outside, be provided with groove between rubber edge and patterned surface, the width of described groove is less than or equal to convex tendon on polyurethane mould
Width, the distance of the bottom of described rubber edge to groove upper surface is less than the height of convex tendon on polyurethane mould.
Preferably, two sides of described groove are 90 ° with the angle of the angle that upper surface is formed.
Preferably, the bottom of described rubber edge is 1.5mm～3mm to the distance of groove upper surface.
Preferably, the width of described rubber edge is 2mm～4mm.
Preferably, the width of groove is equal to the width of convex tendon on polyurethane mould.
Preferably, the cross section of described rubber edge is triangle or trapezoidal.
The utility model has the advantage of:
1, technique of the present utility model is simple, adds rubber edge and groove, utilizes rubber edge and groove by polyurethane mould
Convex tendon on tool embeds in sheet rubber so that sheet rubber is connected more tight with the joint portion of polyurethane mould, thus avoids overflowing
The generation of material phenomenon, reduces the percent defective in production process；
2, this utility model adds rubber edge in the outside of patterned surface, and when Polyurethane Perfusion, polyurethane can be by rubber
While be wrapped in inside so that sheet rubber is more firm with the combination of polyurethane, it is not easy to phenomenon of coming unglued.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is this utility model structural representation after the sheet rubber being combined with polyurethane embeds polyurethane mould；
In figure: 1, polyurethane mould；2, convex tendon；3, patterned surface；4, rubber edge.
Detailed description of the invention
Embodiment 1
As it is shown in figure 1, a kind of sheet rubber for being combined with polyurethane, it mainly includes patterned surface 3 and rubber edge 4, institute
The patterned surface 3 stated is provided with decorative pattern, and described rubber edge 4 is arranged on the outside of patterned surface 3, sets between rubber edge 4 and patterned surface 3
