Description

Paint containing a natural materials and producing method thereof

The present invention relates to a paint containing a natural material and a method of manufacturing the same, and more particularly, the natural pattern is alive by using a natural material of the natural material, and in particular, it is not only environmentally friendly by using a component harmful to the human body, The present invention relates to a paint containing a natural material having good resistance to scratches and excellent in concealment and coating appearance, and a method for producing the same.

The first use of paint was in the Stone Age, when the Cro-Magnon people painted charcoal or stone mixed with animal blood and tree essences and painted them on the walls. Afterwards, the Egyptians developed them and added various pigments to casein ( Casein) was used to prepare and use paints, and full-scale synthetic resin paint began after the 1920s industrial revolution.

These paints give a variety of colors and luster to the objects to beautify them in beautiful colors, as well as to provide the function of environmental protection, which protects the beauty of the object by the coating film. It also gives special functions such as fire protection and heat resistance. There are various types of paints, but they can be divided into water-based and oil-based paints, and both have unique characteristics and uses. By applying such paint to the surface of an object, the surface of the painted object is protected from fouling or corrosion and the beauty is doubled. In addition, compared to the surface treatment such as plating, such a painting can be easily used by anyone with a paint brush and paint is a situation that is used a lot in the home.

As such, paints and coatings thereof have been used in various fields for a long time because of simple and economical facilities and technologies, but recently, excellent synthetic resins corresponding to the purpose have been gradually developed and put into practical use, and their use in terms of chemical resistance and weather resistance. Is the increasing trend. In addition, according to this new painting method is progressed, the development of the coating technology such as automatic painting by the conveyor method using the electric or mechanical force or painting by the robot is remarkable. In this way, the painting helps to further increase the value of the product as the final finish of the article.

As described above, paints have been developed for a long time and have been developed in various compositions for various uses. In particular, water-based paints have conventionally coated paint compositions mainly composed of synthetic resins such as vinyl resin emulsions or acrylic resin emulsions on cement buildings, Easily detached or discolored to shorten the life, in particular, the waste of the synthetic resin has a disadvantage that it is not environmentally friendly to pollute the ambient air due to the various volatile components contained in the paint for a long time after coating.

Moreover, in the context of intensifying environmental regulations for volatile substances, the development of highly functional paints to solve these problems is required.

Meanwhile, a large amount of waste egg shells are generated in a food company. However, proteins such as residual egg white and egg film having high perishability among wastes discarded after using egg white and egg yolk, which are the contents of eggs, are used in food companies to recycle them. The egg shell membrane was separated and removed by centrifugation and alkali addition, and the egg shell membrane was used for livestock feed. However, the egg shell membrane was separated by centrifugation and alkali decomposition and then removed. In the use of calcite as a calcium for livestock feed, it is difficult to separate residual egg whites or eggs from egg shells and costs are excessive, so they are not economically viable due to problems such as secondary waste generation.

In order to solve this problem, Korean Patent Application No. 2001-0001951 discloses proteins used in natural wallpaper and natural paints with excellent preservation and physical properties by coordinating with egg complexes without separating egg whites, eggs and egg shells. Disclosed is a method for preparing a coordination polymer calsite compound, and Korean Patent Publication No. 1990-0006607 describes a printing agent composed of yellow and antiseptic low alcohol, colorant and varnish, and Korea Patent Publication No. 1989 -0012040 is a pattern of egg, paste, wax, and then placed in a drum cage and rotated with pumice immersed in sodium hypochlorite solution or calcium solution, and rotated together with the pumice for a certain period of time, and then with the denim product. Due to the mutual friction of pumice, the pattern part becomes dark blue with respect to the other part. Although the technology for such a method of creating a pattern's products, the conventional technologies, such as the circumstances are not a technology with the yolk of the egg, mainly itjineun give a big help, recycling of egg shells.

Therefore, the present invention is to provide an environmentally friendly paint and a method of manufacturing the same that can prevent the volatile components harmful to the human body after coating, which is a general problem of the conventional paint.

Still another object of the present invention is to provide a manufacturing method capable of mass-producing eco-friendly paints at low cost by using waste egg shells, which may cause environmental problems, as an easy paint material that does not separate egg whites and eggs from egg shells. It is to.
