Abstract
To prevent the occurrence of easy separation between an outsole and an FRP resin sheet for the reinforcement thereof by applying polyurethane resin to the outsole, and forming the FRP resin sheet with a fabric layer and a resin layerselected from a group of polyamide resin, polyolefine resin and a mixture thereof. An outsole 4 is formed together with a resin section occupying a major sole portion and an FRP resin sheet 3. Also, the sheet 3 is formed with a fabric layer l and resin layers 2 laid so as to clamp the layer 1. The layer 2 is made of resin selected from a group of polyamide resin, polyolefine resin and a mixture thereof. In this way, a part of the outsole 4 is replaced with the sheet 3, thereby reinforcing the outsole 4 and providing a high quality sole. As a way of the replacement, the sheet 3 may be used for the upper section of the toe of the outsole 4. Also, the center of the outsole 4 or the bottom section thereof may be replaced with the sheet 3. In this case, an integral molding process is used, or the outsole 4 and the sheet 3 are separately molded and, then, bonded to each other with an adhesive or via fusion or the like.
Description
Technical field
The present invention relates to a kind of sole, its part is substituted by fibre-reinforced resin plate.
Background technology
So far, the sole of footwear is strengthened with various reinforcing materials.For example, reinforcing material is a kind of fibre-reinforced resin plate, and it is made with thermosetting resin such as epoxy resin, mylar, phenolic resins etc., and strengthens with fabric or by the non-woven pad that carbon fiber is made.This reinforcing material can be embedded in the sole, or by adhesion means as sticking on the sole with adhesive.
But because the rigidity modulus of fibre-reinforced resin plate is higher than main polyurethane resin or polyamide as sole body, therefore it has hindered the flexible of sole, and fibre-reinforced plastic material is out of shape because of crooked, and may cause and the sole body unsticking.
In order to improve fiber-reinforced resin plate and sole body to be total to capacitive, carried out multinomial research, for example Japanese Utility Model publishes 62 (1987)-119804, but above-mentioned the fiber-reinforced resin material and the interface unsticking problem between the sole body that cause because of bending fully do not solve.
Summary of the invention
The inventor has studied the combined situation of the resinous type of fiber-reinforced resin plate and sole body and has carried out various tests, for example peel strength.The result finds that unexpectedly the specific combination of some resin can improve above-mentioned interface unsticking greatly.
Therefore the invention provides a kind of sole that is made of TPU, wherein a part is substituted by the fiber-reinforced resin plate, and this plate contains the resin that one deck fiber and one deck are made of thermosetting polyurethane resin.
The present invention also provides a kind of sole that is made of TPU, and wherein a part is substituted by fibre-reinforced resin plate, and this plate contains the resin that one deck fiber and one deck are made of the resin that is selected from polyamide, polyolefin and its mixture.
The present invention also provides a kind of sole that is made of the thermoplastic polyamide resin, and wherein a part is substituted by the fiber-reinforced resin plate, and this plate contains the resin that one deck fiber and one deck are made of the resin of the mixture that is selected from polyolefin or polyolefin and polyamide.
Description of drawings
Fig. 1 represents to be used for the sectional view of the fiber-reinforced resin plate of sole of the present invention.
Fig. 2 to 4 has shown the placement location of fiber-reinforced resin plate 3 in sole of the present invention.Fig. 2 display fibers strengthens the top that resin plate 3 is placed on sole toe portion, and sole body is represented with 4.Fig. 3 display fibers strengthens resin plate 3 and is embedded among the toe portion of sole.Fig. 4 display fibers strengthens the bottom that resin plate 3 is placed in sole toe portion.
The specific embodiment
In this manual, sole is strengthened with a kind of reinforcing material, but the part except that reinforcing material in the sole is referred to as " sole body " or " body of sole ".
The invention provides following three kinds of combinations of the resin of the resin of sole body and fiber reinforced plastic resin plate.
| The sole body resin | The resin of fiber-reinforced | |
| ① | Thermoplastic polyurethane | Heat- |
| ② | Thermoplastic polyurethane | Polyamide, polyolefin or polyamide and polyolefinic mixture |
| ③ | Polyamide thermoplastic | The mixture of polyolefin or polyolefin and polyamide |
In last table, term " thermoplasticity " refers to a kind of performance of resin, and resin is softening or mobile when promptly heating, and then solidifies during cooling.Term " thermosetting " refers to a kind of performance of resin, promptly the hardening of resin reaction can take place during heat treated.In the situation of heat-curable urethane, the cure reaction occurs between isocyanate group and the oh group, causes three-dimensional cross-linked.Thermoplastic polyurethane mainly contains a linear polymer with urethane bonds, but does not have active group when heating.
Polyamide is a kind of resin that can obtain from many suppliers, and wherein representational example is a nylon, nylon-6 for example, nylon-66, nylon-6 9 etc.Polyamide has amido link on its main polymer chain, get by diamines and binary acid reaction usually.
Polyolefin is a kind of with ethylenic unsaturation hydro carbons monomer such as ethene, propylene, the resin that butylene etc. get by polymerization.
If select above-mentioned resin combination, then can improve the interfacial adhesion between sole body and the fiber-reinforced resin plate greatly, the fiber-reinforced resin plate has obtained sufficient improvement, and the fiber-reinforced resin plate provides outstanding sole to strengthen effect.
Fibrage in the fiber-reinforced resin plate can be long stapled yarn fabric, also can be the short fiber that is scattered in the resin base.Fiber can be any fiber that is used for the fiber-reinforced resin field, for example natural fiber such as cotton, wool; And synthetic fibers such as carbon fiber, aromatic polyamide fibre, aliphatic polyamide fibre, polyethylene fibre, boron fibre, polyester fiber, acrylic fiber etc.Fiber is preferably crossed with adhesive treatment.Consider carbon fiber most preferably, for example carbon fiber-5T347 that can obtain from Japanese Toray Industries Inc. based on intensity and elasticity.
The preparation of fiber-reinforced resin plate can perhaps will be with fibrolaminar resin plate to press mutually with another piece resin plate by fibrage being sticked at resin plate by above-mentioned fibrage being placed compacting then between resin plate then.When the resin that is used for the fiber-reinforced resin plate is liquid, liquid infiltration can be gone into fibrage and be solidified then.Preferably, the weight ratio of the resin fibre of fiber-reinforced resin plate is 5/95-90/10.
A representation example of fiber-reinforced resin plate of the present invention is shown in Fig. 1.Fig. 1 is the sectional view of fiber-reinforced resin plate, and wherein 1 represents fibrage, and 2 is the two layers of resin layer, and they have clamped fibrage 1.
Fig. 2 to 4 has shown the placement location of fiber-reinforced resin plate 3 in sole of the present invention.Fig. 2 display fibers strengthens the top that resin plate 3 is placed on sole toe portion, and sole body is represented with 4.Fig. 3 display fibers strengthens resin plate 3 and is embedded into sole toe portion.Fig. 4 display fibers strengthens the bottom that resin plate 3 is placed on sole toe portion.
Sole of the present invention can be produced with methods known in the art.For example, can make the fiber-reinforced resin plate in advance, be placed in the mould then, thereby the resin that adds sole body in mould makes sole of the present invention (a slice method of forming).Perhaps, can be molded as fiber-reinforced resin plate and sole body respectively, bond them together with adhesive or fusion-bonding process then.A slice method of forming preferably.
