Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for anti-slip and waterproof treatment of leather used for grip surface materials of golf gloves, tennis rackets, etc. to obtain anti-slip and waterproof effects.

Prior Art A method has already been devised in which leather is impregnated with silicone rubber in order to provide it with anti-slip and waterproof effects.

Problems to be Solved by the Invention However, when treated using this method, the pliability peculiar to leather is lost and the leather becomes hard and stiff to the touch.

Therefore, the present invention was devised for the purpose of providing a processing method that provides anti-slip and waterproof effects without losing the suppleness of leather.

Means for Solving the Problems The present invention provides low-temperature or room-temperature curing liquid rubber.
Add oil and thinner, and if necessary, add an oil-based colorant and mix. Dip the leather into this mixed solution while stirring to impregnate the leather with this solution. After this, take out the leather and allow it to be impregnated. This is an anti-slip and waterproof treatment method for leather, which is characterized by curing liquid rubber.

The present invention will be described in detail below.

First, oil and thinner are added to liquid rubber, and if necessary, an oil-based colorant is added to prepare a liquid.

The liquid rubber used here may be urethane-based or the like, but silicone rubber with excellent cold resistance is suitable. In addition, when curing to form a rubber elastic body after impregnation, in order to avoid damaging the leather, we use a low-temperature curing type that does not require too high a temperature and can be heated to around 100 to 150°C, or a room-temperature curing type that cures at room temperature. use something

The oil is impregnated into the leather together with rubber to reduce the stiffness of the leather, and any type of oil may be used, including mineral, vegetable, and animal oils. However, it is desirable to use a stable and odorless material, and silicone oil or the like is suitable.

The thinner is used to lower the viscosity of the liquid mixture and facilitate impregnation, and when a colorant is used, it serves as a solvent for the colorant. This thinner can be used as is for ordinary paints, such as toluene.

The ratio of liquid rubber, oil, and thinner varies depending on the thickness of the leather and the degree of softness desired, but approximately 1 part liquid rubber to 0.3 to 2 parts oil and 2 to 6 parts thinner (both by volume). Bye.

Anti-slip and waterproof treatment can be performed using a mixture of the three above-mentioned liquids, but since this mixture contains oil and thinner, the leather to be treated may be dyed in advance. It is difficult to color the leather after it is bleached, and even if it is colored after this treatment, the colorant does not penetrate into the leather and is easily peeled off. Therefore, when coloring leather, a coloring agent is added in addition to the three liquids mentioned above, and the coloring process is performed at the same time as this treatment. This coloring agent is suitably oil-based such as synthetic resin paint, and the amount should be determined as appropriate depending on the desired color depth, etc., and should be approximately 0.5 to 2 (volume ratio) to 1 part liquid rubber. .

Next, the leather is immersed in this mixed solution while stirring to impregnate the leather with this solution.

The components of this liquid mixture, except for the coloring agent, do not dissolve in each other and are easily separated due to the difference in specific gravity, so stirring must be carried out constantly during dipping.

The leather used for this treatment may be either natural leather or artificial leather, and even if it is in the form of a sheet,
It may also be a sewing agent.

For impregnation, if it is a thin shape such as a sheet or a glove, wring it out in the liquid and knead it by hand for 5 to 10 minutes, or 30 to 60 minutes.
It may be sufficient to leave it for a minute, or for thick leather, etc., a device for impregnating castings or the like with plastic may be used, the pressure may be reduced to remove the air in the leather, and then the leather may be immersed in a liquid and pressurized.

After impregnation, the leather is removed from the liquid and the liquid rubber is cured to complete the process.

For this curing, if the rubber is a room-temperature curing type, it is sufficient to simply leave it, and if the rubber is a low-temperature curing type, it is sufficient to heat it using hot air or the like.

Example Room temperature curing liquid rubber (SE9140, manufactured by Three Bond Company) 1 containing reactive polysiloxane as the main ingredient, dimethyl silicone oil (Three Bond Company, Ltd.)
Add SH200) 1, then add 4 parts thinner and 1 part synthetic resin paint and mix. Dip the cowhide for gloves into this, stir the solution with your hands and squeeze it for 10 minutes, take it out and about 3 I dried it in the shade for a while.

The leather treated in this way had a supple feel, was well colored, and had sufficient anti-slip and waterproof effects.

Effects of the Invention According to the treatment method of the present invention, the treated leather has no stiffness and has a supple feel, and can be well colored by using a colorant. Furthermore, the treated leather has an anti-slip and waterproof effect due to the impregnated rubber, and this effect does not diminish even when the leather surface is abraded.

Therefore, this treatment method can be widely used for leather used in sports gloves such as golf and baseball, grip surface materials for golf clubs and tennis rackets, and leather clothing such as bags and jumpers.
