Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is such that when walking in a place where oil is scattered, such as a rainy mud road or a factory, dirt such as mud 6, water, and oil adheres around the outsole 2 of the footwear, and the dirt is removed even when washed. It proposes a structure of footwear with antifouling property that overcomes the difficult and extremely unsightly situation.

[0002]

[Prior art]

 As a footwear material for antifouling property, there is a product in which the cloth 3 is processed with a fluorine-based or silicon-based resin, but the footwear outsole 2 composed of rubber or resin, the tape 4 around the footwear 4, and the toe guard. No. 5 and the like are liable to get dirt and are hard to remove.

[0003]

[Problems to be solved by the device]

 Footwear with fluorine or silicon resin coated on the upper cloth 3 has a structure that easily repels dirt such as mud 6, water, and oil on the upper cloth 3, but the outsole 2, tape 4, toe guard. Since there is no antifouling measure around the bottom of 5 etc., there is a problem that dirt is conspicuous conversely compared with Kofu 3.

In the present invention, the combination of the upper cloth 3 coated with fluorine or silicon resin, the outsole 2 coated with fluorine or silicon resin oil, the tape 4, the toe guard 5, etc. It enables the construction of dirty footwear.

[0005]

[Means for solving problems]

 The present invention coats the surface of the outsole 2 of footwear, the surrounding tape 4, the toe guard 5 and the like with fluorine or silicone resin oil to protect a place where rainy mud or a place where oil is scattered in a factory. Even when walking, due to the water-repellent, oil-repellent, and antifouling effect of the coating material 1 on the outsole 2, the tape 4, and the toe guard 5, the outsole 2 and the surrounding area are protected from dirt such as mud 6, water and oil. As well as repelling, you can easily remove stains once attached.

[0006]

[Work]

 The surface of the outsole 2, which is made of rubber or resin, the tape 4, the toe guard 5, etc., has an adhesive property against dirt such as mud 6, water and oil. It is easy to get the dirt that occurs in, and it is very easy to get dirty. The surface of the outsole 2, the tape 4, the toe guard 4, etc. of footwear composed of such rubber or resin is chemically inert, non-adhesive, and has excellent releasability By coating with oil, it is difficult for dirt to adhere, and even if it adheres, it can be easily removed.

[0007] The antifouling mechanism of the present invention is explained by the chemical structure of silicone resin oil, because silicon has a helix structure (coil shape) and the methyl group located outside the coil structure can rotate freely. Exhibits unique interface properties such as water repellency and releasability.

[0008]

【Example】

 The structure of the footwear having antifouling property according to the present invention will be described in detail. The surface of the outsole 2, the tape 4, and the toe guard 5, which are made of rubber or resin, are spray-coated with fluorine or silicone resin oil or By dipping and coating, the structure of footwear with antifouling properties is possible.

The materials of the coating material 1, the outsole 2, the tape 4, and the toe guard 5 according to the present invention will be described in detail below. The coating material 1 is chemically inert and has excellent non-adhesiveness and releasability. Fluorine-based or silicone-based resin oil with a viscosity in the range of 0.5 to 100 Pa · S can be used. In the present invention, the coating material 1 having a viscosity in the range of 1 to 5 Pa · S is used for coating workability and protection. It had excellent stain resistance.

Next, the materials of the outsole 2, the tape 4, the toe guard 5, and the coating material 1 will be described. The rubber compounding materials of the outsole 2, the tape 4, and the toe guard 5 are rubber, natural rubber, styrene-butadiene rubber, Polybutadiene rubber, nitrile butadiene rubber, chloroprene rubber, isoprene rubber, ethylene vinyl acetate rubber, urethane rubber, etc. are used.Sulfur, fillers, vulcanization accelerators, antioxidants, softeners, etc. are used as compounding agents. The rubber and the compounding agent are kneaded with a closed kneading machine or an open roll, and the sheet is cut to a certain thickness, cut, or vulcanized and molded with a hot press.

In the case of resin, polychlorinated thermoplastic elastomer, polystyrene thermoplastic elastomer, polyurethane thermoplastic elastomer, ethylene vinyl acetate thermoplastic elastomer, polyamide thermoplastic elastomer, 1,2-polybutadiene elastomer A thermoplastic elastomer is used, and the outsole 1 is molded by a transfer molding machine.

The antifouling mechanism of footwear according to the present invention will be described with reference to the drawings. In the embodiment shown in FIG. 1, the state in which mud 6 adheres to the surface of the tape 4 is shown. Since it is chemically inert and non-adhesive, it is difficult for mud to adhere, and even if it adheres, it has antifouling properties that can be easily removed by washing with water.

As an example of a method of adhering the outsole 2 and the instep cloth 3 using the coating material 1 which is an embodiment of the present invention, the adhesive surface of the outsole 2 is buffed, urethane-based or A chloroprene-based treatment agent is applied, then a urethane-based or chloroprene-based adhesive agent is applied beforehand, and the urethane- or chloroprene-based treatment agent is also applied to the adhesive surface of the upper cloth 3, and then a urethane-based or chloroprene-based adhesive agent is applied. Apply a chloroprene-based adhesive and attach the outsole 2 and upper 3 together.

[0014]

[Effect of device]

 In the antifouling footwear structure according to the present invention, the coating material 1 used on the surface of the outsole 2, the tape 4, and the toe guard 5 prevents dirt such as mud 6, water and oil, and at the same time It also has the feature that stains attached to it can be easily removed, and the stainproofing effect will last long even after repeated washing.
