The present invention is a coating composition for a high-elasticity plastic material comprising a water-dispersible acrylic urethane resin (hereinafter referred to as 'AUD') and a water-dispersible polyurethane resin (hereinafter referred to as 'PUD') and its It relates to a manufacturing method. More specifically, the present invention improves the working environment by replacing the conventional oil-soluble paint composition used in shoes or golf balls, and does not use an organic solvent, and is environmentally friendly, minimizing the stress of the plastic material by the organic solvent, the defective rate AUD and PUD designed to reduce the coating failure rate due to the prevention of coating dust scattering, to provide excellent coating properties of the coating film, to ensure high reliability, and to improve productivity by shortening the drying process. A top coat composition for a high elastic plastic material and a method for producing the same.

Due to the diversification of designs and colors from everyday life products such as shoes, sports equipment, and protective equipment to sports goods, the necessity of painting on the exterior is indispensable, thus minimizing the influence of paint on the applied materials (during painting Product due to material deformation caused by erosion Preventing the occurrence of defects is urgently required in the industrial field. As a way to meet the needs of the industrial field in terms of paint, there is a method such as minimizing or non-solvent and paint solubilization of the solvent contained in the paint. In particular, when painting on high-elastic plastic material is required, the color topologies used should have excellent adhesion with the high-elastic plastic, which is the target material, and the coating film flexibility and flexibility, which is a required property according to the material properties and application, It should be excellent, and the color realization and holding power of the coating film itself should also be excellent.

Color coating paints currently applied in the high-elastic plastic material coating process in the domestic footwear and sports equipment industry, for example, usable paints, the characteristics and application conditions of the general coating composition are summarized as shown in Table 1 below. Can be represented.

Item shape Content (% by weight) Paint Composition Suzy Acrylic urethane resin 20 to 30 solvent Ketones and Aromatic Organic Solvents 50 to 60 Pigment Oil-soluble dyes and pigments 5 to 10 additive Surface conditioner, etc. 5 to 10 Dryer Room temperature drying or forced drying (80 ℃ * 40 minutes) Film thickness 15 to 20 μm

Some multinational companies have applied water-soluble color coats in high-elastic plastic coatings, but now rely entirely on imports. In the case of the useful color topologies currently used, the solid content of the paint is 20 to 30% due to the characteristics of the paint, and the wetting and etching effect on the material surface by the large amount of solvent components contained in the paint It is excellent in adhesion and compatibility with materials, but deterioration of product structure design quality due to deformation of materials due to excessive erosion of the material surface by a large amount of solvent components contained in paint. There is a problem in that the incidence of defective products is high.

In particular, as long as an oil-soluble paint is used as the color coat for the high-elastic plastic material, problems such as erosion of the high-elastic plastic material by the solvent contained in the paint and deformation of the material may not be solved. In order to overcome these technical limitations, researches are being conducted mainly on domestic paint companies and related industries, but at present, no differentiated technology has been published for color coating of plastic materials for high elasticity.

In developed economies such as Europe, almost all oil-soluble paints have been replaced by water-soluble paints in terms of environmental preservation.In addition, paints containing water-soluble resins with excellent film properties such as AUD and PUD and excellent coating properties It is a state. In the case of water-soluble paints, various applications are applied from industrial sectors to bottom coats, color coats, and transparent coats. However, industrial sectors related to high-elasticity plastic materials such as shoes are environmental pollution-inducing industries, and most production bases include China. As it is being transferred to India and Southeast Asia, it is a general reality that the research and development of the coating for the high elastic plastic material is not a challenge.

As mentioned earlier, China and Southeast Asia, which attract most of the industrial pollution-causing industries in developed countries, already have many social problems due to severe environmental pollution. The legalization and enforcement of strong regulatory policies on pollution are being reviewed and implemented. The active and efficient response to this is the acceptance of paints and the promotion of research and development.

In Korea, from July 2007, regulations on volatile organic compounds (VOCs) targeting industrial companies that emit air pollutants are expected to be implemented in full scale. Voluntary organic compounds are regulated or planned to be implemented in response to environmental preservation. In particular, in the developed countries, the development and application of environmentally-friendly products through the acceptance of paints at the environmental preservation level have reached a considerable stage. However, in Korea, active legal regulations at the national level Despite its anticipation, product applications on industrial sites are still small. In order to prevent air pollution, it is essential to apply eco-friendly materials that do not generate harmful chemicals and gases, and as a fundamental solution, development of water-soluble paints is urgently required.

Therefore, the object of the present invention is to replace the conventional oil-soluble paint composition used in shoes, golf balls, etc. by using an organic solvent to improve the working environment, environmentally friendly, minimize the stress of the plastic material by the organic solvent to reduce the defective rate AUD and PUD are designed to reduce the paint failure rate due to the prevention of paint dust scattering, to provide excellent coating properties, to ensure high reliability, and to improve productivity by shortening the drying process. It is to provide a top coat composition for an elastic plastic material and a method of manufacturing the same.

Another object of the present invention is to cope with the regulation of volatile organic compounds according to environmentally friendly paint formulation design, to minimize the stress and failure rate of plastic materials by paint-containing solvents, and to prevent paint dust scattering (painting gas) It is possible to reduce paint defect rate and improve working environment, secure adhesion of coating material and reliability, and improve productivity by reducing paint usage and improving productivity by shortening drying process. It is to provide a top coat composition for an elastomer plastic material and a method of manufacturing the same.
