 Further, the present invention aims at solving the problem of short pot life in use by using a reaction retarder as a silicone treating agent.

In order to accomplish the object of the present invention as described above, the present invention provides a polymer electrolyte membrane comprising 100 parts by weight of a base polymer solution mixed with a polymer resin and a solvent;

There is provided a composition containing a silicone rubber hardener, a reactive additive, a reaction retarder and an auxiliary additive to provide a silicone natural leather texture imparting and gloss controllable silicone surface treatment agent.

It is preferable that at least one polymer resin selected from the group consisting of silicone polyol, silicone polymer, silicone intermediate elastomer silicone rubber curing agent is used.

It is preferable that at least one solvent selected from silicone solvents (Dow Corning Inc. (DC-245)), E-A (Ethyl Acetate), IPA (Isoprooyl Alcohol) and Ethyl Alcohol Methanol is used.

It is also preferable to use modified dimethylsiloxane and / or hydroxy silicone modified polyacrylate as the reactive additive.

As an auxiliary additive, at least one of silica, a dispersant, a silicon bead, a UV absorber and an antioxidant may be selected and used.

In addition, manufacturing cost loss and housework time due to short usage time, which has been problematic in use, can solve processing problems.

Hereinafter, the present invention will be described in more detail with reference to preferred embodiments. The following description is intended to assist in the understanding and understanding of the present invention, but is not to be construed as limiting the invention thereto. It will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention as set forth in the following claims.

In order to carry out the present invention, firstly, 3 to 80% by weight of a polymer resin selected from silicone polyol, silicone elastomer, silicone polymer and silicone rubber curing agent is added to polymer molecules; A base polymer solution having a ratio of one or more solvents selected from a silicone solvent (DC-245), E-A, IPA, ethanol and methanol at a ratio of 20 to 97 wt% is prepared.

3 to 30 parts of a silicone rubber curing agent serving as a curing agent for controlling the tacky on the basis of 100 parts of the basic polymer solution, 1 to 5 parts of hydroxy silicone modified polyacrylate as a silicone reactive additive for imparting a surface tacky and natural texture effect , And a mixture of 0.01 to 3 parts of a reaction retarding agent (Cyclopentanone: chemical name) is added to increase the pot life and to easily control the workability.

0.1 to 16 parts of an auxiliary additive may be added to the mixture based on 100 parts of the polymer solution. Preferably, 100 parts of the base polymer solution is added to 0.1 to 5 parts of a UV absorber to prevent surface discoloration by ultraviolet rays, 0.1 to 5 parts of an antioxidant, 1 to 3 parts of silica to adjust surface gloss, 1-5 parts of silicone beads and 0.1 to 5 parts of a dispersing agent.

In the practice of the present invention, the reason why one or more polymer resins selected from silicon polyol, silicone polymer, silicone elastomer, and silicone rubber curing agent is used as the main polymer for use in the silicone surface treatment agent of the present invention is that the present invention The weight ratio between the compositions is not limited. However, the reason for using 3 to 80 wt% of the whole base polymer solution is that the coating process (application amount) is easy This is to maintain the proper ratio with other additives.

In addition, the solvent is used for controlling the viscosity for ease of the coating process and for obtaining a stable solution of the polymer. The reason for setting the content of the solvent to 20 to 97 wt% is that when the content is 97 wt% or more, The coating amount is too small to achieve the object of the present invention.

The reason for not using a non-polar solvent (TOL, XYLENE) having good compatibility with a silicone elastomer is that it is a harmful substance for furniture, shoes and mat, and regulates the use thereof.

The reason for using the silicone rubber curing agent as a curing agent is to maximize the crosslinking density to prevent surface tackiness. The reason for using the silicone rubber curing agent is to provide a natural texture, gloss control, This is because it is necessary to obtain the naturalness, and the curing agent is silicone to achieve the object of the present invention.

The reason why the addition amount is set as described above is that it is difficult to obtain the effect of the present invention sufficiently when the amount is less than the above amount, and the degree of the effect is not further increased and the price increase is caused.

The reason why the amount of the UV absorber to be used for preventing discoloration of the surface due to ultraviolet rays is 0.1 to 5 parts is because the effect is insufficient when the amount is less than 0.1 part and the compatibility with the silicone resin is more than 5 parts, In order to prevent the occurrence of shocking during storage, the antioxidant and the silica used as a surface gloss regulator are preferably used in the above-mentioned amounts for the same reason.

The silicone-based reactive additive used for controlling the surface energy is used for minimizing the surface energy of the coating film surface through reaction with silicon. The amount of the silicone-based reactive additive is 1 to 5 parts. If the amount is less than the above range, The effect of the present invention is not increased any more, and it is because of the compatibility with the silicone elastomer, and in order to obtain the rationality of the manufacturing cost.

The reason for using at least one of silicone solvent, EA, IPA, ethanol and methanol for viscosity and solids control is that the viscosity is lowered and the volatilization rate is faster, to be.

Also, silicone beads can be added for imparting natural leather texture, gloss control, and tannery improvement. The reason why the content is as described above is that it is difficult to expect the effect when the addition amount is less than the above amount, The effect can not be expected.

The antioxidant, antifoaming agent, anti-settling agent and the like in the present invention may be any conventional ones.
