Description

Non-slip holder for finger and its manufacturing method {FINGER HOLDER FOR PREVENTING SLIP AND METHOD FOR THE PREPARATION THEREOF}

The present invention relates to an anti-slip holder, in particular a non-slip holder that can effectively control the slip when handling fishing lures and a method of manufacturing the same.

Fishing lures are mainly chosen as worms, shrimps, loach or insect larvae, depending on the ocean or freshwater fishing and species of fish. In particular, the lure in sea fishing is used lugworm, loach or shrimp, etc. In inserting the bait into the fishing hook, there are many difficulties due to the discharge from the fishing bait. In other words, due to the secretion from the fishing bait slippery hands difficult to insert correctly into the hook, it takes a lot of time to insert the fishing bait slippery hands are often injured by the hook. These baits also cause disgust when touched directly by hand.

In order to solve the above problems, conventionally, palms of cotton gloves have been coated with rubber or rubber gloves, natural leather gloves or artificial leather gloves have been used. However, such cotton gloves, rubber gloves, natural leather gloves or artificial leather gloves are very thick and swollen, there is a problem that the movement of the finger is not flexible and difficult to operate fishing bait when fitted to the finger.

Accordingly, it is an object of the present invention to provide a non-slip holder for a finger and a method for manufacturing the same, which have good adhesion to a hand, are easy to wear, and are non-slip.

In order to achieve the above object, the present invention provides a non-slip holder and a method for manufacturing the finger, characterized in that the sand is coated on the outer surface of the thimble tube of the size of the finger.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a non-slip holder for a finger and a method for manufacturing the same, wherein the sand is coated on the outer surface of a finger-sized tube (thimble). Can be prepared by:

Iii) first coating an adhesive on an outer surface of a tube (thimble) whose one end is clogged with a size to which a finger can be inserted;

Ii) coating sand on the tube and drying at a temperature of 60 to 90 ° C. for 10 to 30 minutes; And

Iii) a second coating of an adhesive on the adhered sand of the tube, drying at a temperature of 60-90 ° C. for 10-30 minutes.

The tube according to the present invention is preferably made of a material selected from the group consisting of natural rubber, synthetic rubber, plastic elastomer resin and cotton fiber.

In addition, the adhesive used in the present invention is preferably selected from the group consisting of a urethane resin, an epoxy resin, a polyester resin and a natural or synthetic rubber-based adhesive excellent in adhesion, and particularly preferably a urethane resin.

The method of coating the adhesive on the tube is most commonly an impregnation coating method, and in each of the adhesive coating steps, the adhesive is used in an amount of 0.3 to 1.0 g / tube.

When the adhesive is coated on the tube, the thixotropic agent can be added to adjust the viscosity of the adhesive. Such thixotropic agents include, for example, whitecarbon (degussa, aerosil-200), clay (engelhards, attagel-50) and the like. The viscosity of the adhesive adjusted by the addition of the thixotropic agent is preferably 400 to 700 cP (centipoise) when the tube is made of cotton fiber in the case of the primary coating, such as natural rubber, synthetic rubber or plastic elastomer resin. In the case of rubber material, 100 to 300 cP is preferable, and in the case of secondary coating, 200 to 600 cP is preferable regardless of the type of tube.

The sand according to the present invention is silica, iron oxide, garnet, aluminum oxide, silicon oxide, calcium carbonate, magnesium oxide, glass, dolomite; Inorganic composites such as alumina silica gel; Hardened | cured material of thermosetting resins, such as a phenol resin or a melamine resin; It is preferred to be selected from the group consisting of metal oxides and other organic compounds, in particular silica gel. In addition, the particle size of the sand according to the present invention is preferably 200 to 500㎛, particularly preferably 350 to 400㎛. If the particle size of sand is less than 200㎛, the coefficient of friction is low and the anti-slip effect is small.If the particle size of sand is more than 500㎛, it hurts the material (e.g. bait) and handles the hand. There is an inflexible problem.

The sand is used in a coating amount of 0.5 to 1.5 g / tube.

In the production of a non-slip holder for a finger according to the invention, the coating of the sand can be made by an electrodeposition spray (electro-coating) method, for example as schematically shown in FIG. That is, the tube is inserted into a mold into which the rubber tube can be fitted, and the sand provided through the hopper is transferred through the conveyor belt to coat the sand on the outer surface of the tube. Other coating methods include a drop or spray coating method using a mixture of an adhesive and sand.

Hereinafter, the present invention will be described in more detail with reference to the following examples.

The insert was impregnated and applied in an amount of 0.55 to 0.60 g / tube. Subsequently, silica gel having a particle size of 250 to 400 µm was sparged in an amount of 1.0 to 1.5 g / tube using an apparatus such as shown in FIG. 3, and then dried at a temperature of 60 to 90 ° C. for 30 minutes. The urethane resin adhesive (molecular weight 8000 to 12000) having a viscosity of 300 to 500 cP was coated and coated on the sand-fixed tube in an amount of 0.6 to 0.8 g / tube, and then dried at a temperature of 60 to 90 ° C. for 30 minutes. An anti-slip holder for fingers was prepared. The holder was aged at room temperature for one week.
