Description

TECHNICAL FIELD [0001] The present invention relates to an ink composition having a multi-purpose slip prevention function, and a method of producing a sheet having a slip prevention function using the composition. [0002]

The present invention relates to a printing ink composition having a multipurpose slip prevention function and a method for producing a sheet having a slip prevention function using the same.

Conventional anti-slip sheets have used a technique of preventing slip by urethane and acryl adhesive materials and solvent dilution such as toluene, methyl ethyl ketone, ethylene acetate and the like, and the non-slip technique using paper, , PE, PP wax, and silicate-based compounds to minimize friction between materials in contact with each other, and silicone-based anti-slip papers through a solvent-based coating solution.

However, in the case of a silica-like piece, there is a disadvantage that scratching of the contact material can occur. In the case of PE, PP wax and silicate-based compound, the slip prevention efficiency is inferior. In the silicone system using a solvent, And there is a problem in the workability hazard part. In addition, there is an inconvenience that it is difficult to cut a non-slip sheet using rubber or plastic as a material in a desired size or shape.

Accordingly, the present inventors intend to produce an ink composition using a silicone resin and a slip prevention sheet using the ink composition. It requires an environmentally friendly sheet that can be attached and detached from a place, such as a cell phone and a writing instrument, on a vehicle or a desk in a narrow space. Currently, in the case of an airplane seat for domestic and foreign airlines, PE lamination is applied to paper, There is a problem that the slip of the food container and the glass caused by the slip can cause danger. In addition, in order to prevent slippage of the ground used for loading pallets of large capacity, one side is coated on the kraft paper to minimize the slip of the ground due to shaking when transporting the forklift, thereby reducing the risk and the environmentally harmless environmentally friendly ink composition, It is necessary to develop an environmentally friendly ink composition which is versatile for preventing the loss of the product value due to sliding of the paper.

Kraft paper is made up of two kinds of products. The paper with a yellow color (UKP) is called kraft paper and the paper with white color is called a back kraft paper. Pulp raw materials used in the production of kraft paper are mixed with UKP and old corrugated containers (OCC). OCC raw materials are mixed with various foreign substances such as wax, hotmelt, asphalt, styrofoam. The wax contained in the wax is a direct cause of the slip of the product and requires a process of raising the coefficient of friction by completely removing the wax.

In the case of kraft paper which is used to transport rice, flour, sugar, cement, etc., it is necessary to accumulate a lot of paper in order to increase the amount of the warehouse. If the kraft paper is slippery, Also, the coefficient of friction is one of the important quality factors because it is directly related to the breakage of the product during transportation.

Kraft paper is manufactured through paper manufacturing, surface label printing and wrapping paper manufacturing process. In order to prevent the slip of conventional kraft paper, it is necessary to use silica / binder in the production process or to increase the content of UKP which is high- The coefficient is improved, but there is a problem that the process is complicated, high cost, low efficiency and productivity. Accordingly, in a kraft paper wrapping paper manufacturing method in which a high friction coefficient acts as an important quality, it is intended to provide a simple and economical method of greatly improving the friction coefficient in the surface paper label printing process of the wrapping paper.

Specifically, in the case of UKP increase or silica / binder coating, the friction angle exhibits a friction coefficient of 10 to 20 degrees, whereas the kraft paper provided with the slip prevention function by the manufacturing process according to the present invention has a much higher friction coefficient of 48 to 51 degrees . In addition, it is possible to increase the OCC content, which is a low cost raw material, and the friction coefficient can be easily adjusted by adjusting the amount of coating (printing pattern) according to the quality level of the user, so that the defective product due to the friction coefficient can be minimized. Therefore, it is possible to simplify the process that can improve the friction coefficient and reduce the cost of the pulp raw material.

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

Examples.

A solventless liquid silicone rubber resin having a double bond capable of addition reaction with a pigment and a crosslinking agent, a reactive diluent of a silicone compound having an unsaturated hydrocarbon having a low viscosity and a low molecular weight (3-methacryloxypropyl-tris ), A leveling agent, a hydrogenpolysiloxane crosslinking agent containing -Si-H bonds, and a platinum catalyst were mixed in a blending ratio (weight) as shown in Table 1 below to prepare a multipurpose slip Resistant ink composition was prepared.

Thereafter, as shown in FIG. 1, the paper was printed using the pattern printing method so as to have a nonslip pattern using the slip inhibiting ink composition. As a result, it was confirmed that the friction coefficient could be maintained while greatly reducing the coating amount according to the printing pattern . Only about 8% of the printed area was coated with the ink composition for preventing slip, which was similar to the coefficient of friction applied on the entire surface. Accordingly, it can be seen that the anti-slip ink composition according to the present invention has a nonslip directly applied to various printing patterns such as a dot, a company logo, and a trademark as shown in FIG. 1, thereby reducing a cost and a coating process.

In addition, kraft paper was printed with the slip control ink composition prepared above, and a kraft paper wrapping paper used as an industrial paper used for cement wrapping paper was produced. As a result, a high coefficient of friction of 48 to 51 degrees was obtained.

The mixing ratio of Examples 1 to 5 was superior in blocking property, and in Example 1, the friction angle was greatly decreased due to an increase in the amount of reactive diluent used. Good results were obtained in the mixing ratios of Examples 1 to 6 in the process viscosity and the viscosity.
