Description

Natural coating compositions comprising lacquer and glue or glue, and methods of making the same,

The present invention relates to a natural coating composition comprising lacquer, glue and / or lacquer and a process for its preparation.

The lacquer obtained from Rhus verniciflua is a natural resin which is not corroded by various acids and alkalis and has excellent properties such as heat resistance, waterproofness, preservation and insect proof. Since ancient times, in Asia, especially in Korea, China, and Japan, a unique lacquer culture has been developed using lacquer. The lacquer coating on the living tools and the weaponry has been recognized as a natural coating with excellent durability because it does not change even when used for a long time because it forms a solid and hard film on the surface as well as luster (National Science Museum, 1995). Recently, it has been confirmed that lacquer has been used for the durability and repairs needed from the ancient times by detecting the fresh ingredients in the joint part of the large pavilion excavated from the Daejungri site of Pyeongtaek excavated from the Pyeongtaek Daechuri site. In addition, it is not known exactly the timing of the preservation, but it has been confirmed that it has been used for restoration of joints in many pottery that have been preserved in the past (Yang Phillian et al., 2005).

Studies on hardening of lacquer are proceeding in various ways at home and abroad. In Korea, there is a case study of drying condition of lacquer using lacquer on a test plate of pine wood and then using chilmate surface (Shin, Sungpil, 2008). In this paper, proper drying conditions were suggested through surface observation and curing rate of lacquer coatings dried at room temperature 25 ± 2 ℃, relative humidity 55%, 75%, 85%. In a humid environment, the cured film showed a slower curing rate than a dried film in a high humidity environment and showed less loss or damage before and after drying of the film. Studies on the physical properties of lacquer are going on overseas. In particular, Japan has made a lacquer culture in the west with black lacquer and lacquer adhesive, and has been conducting various studies and seminars on lacquer. Among them, Professor Miyakosi's team at Meiji University has been conducting research on room temperature hardening of lacquer using enzymes oxidation through repetition of the Kurome process (Lu et al., 2004, Lu et al., 2005a, Lu et al., 2005b, Lu , 2006).

Lacquer has the characteristic of hardening only in high temperature or high humidity environment. The drying time is required to be about 5 hours at a high temperature of 100 ° C or more, and the drying time is more than 1 to 2 hours at a temperature of 200 ° C or higher (Yang Phillian et al., 2009). At room temperature, it takes about 6 hours to 24 hours at relative humidity of 70 ~ 80%, and does not cure at humidity below 50% (Lu et al., 2004).

Accordingly, the present inventors have found that natural coating compositions including lacquer, glue or glue have a suitable viscosity and can be dried even under an environment of room temperature and relative humidity of 50 ± 5% unlike conventional lacquer, Confirming that the surface is smooth, the present invention has been completed.

In mixing the glue or the lacquer according to the present invention with the lacquer, the quality and characteristics of the lacquer deteriorate as the ratio of the lacquer added to the lacquer is higher. When the amount of the lacquer or the lacquer added exceeds 30% The mixing ratio can be mixed in a weight ratio of lacquer with lacquer in a ratio of 1: 5 to 20, and preferably in a weight ratio of 1: 6 to 19 , And in the case of glycols, they may be mixed in a weight ratio of 1: 2 to 20, and preferably in a weight ratio of 1: 2 to 19.

The natural coating composition according to the present invention can be preferably used for preserving artifacts. The artifacts may include, but are not limited to, soft pottery, hard pottery, ceramics, wood artifacts, metal artifacts, tiles, and the like.

In one embodiment of the present invention, it has been confirmed that the natural coating composition according to the present invention has a suitable viscosity. The natural coating composition according to the present invention exhibited a constant tendency according to the ratio of the addition of bridges and bridges to the natural bristles, and the viscosity of all the samples increased more than that of the natural bristles. As the viscosity increases, it can compensate the problem that the viscosity can be easily lowered when the lacquer is used.

The natural coating composition of the present invention is prepared by mixing (1) a fish meal or glue with water at a weight ratio of 1: 4 to 10, then at 40 to 70 ° C, glue for 20 minutes to 1 hour, step; And (2) mixing the solution of the superabsorbent of step (1) with lacquer at a weight ratio of 1: 2 to 20, or a solution of superabsorbent lacquer to lacquer at a weight ratio of 1: 5 to 20 .

Gelatin, which is the main component of the glue, can be refrigerated for 12 to 48 hours since the swelling speed is the best at 4 to 5 캜 before the glue is soaked in step (1).

In step (1), the fish or glue may be mixed with water in a weight ratio of 1: 4 to 12, preferably 1: 4 to 10, more preferably 1: 4, 1: 7 or 1:10 Lt; / RTI > The bath temperature can be 40 to 70 캜, preferably 60 to 70 캜. The bath time may be 20 minutes to 1 hour for glue, and 4 to 12 hours for glue, preferably 8 hours.

In step (1), after the fish is soaked in water, the balloon that has escaped from the slime can be filtered with the gauze to remove the residue. Since the bridges are neutral and have acid or alkali properties, the adhesive strength is lowered. Therefore, the pH of the bridged brine solution may be measured to confirm that the bridges have a neutrality of 6 to 7.

In the step (2), the solution of the superheated glue may be mixed with the lacquer in a weight ratio of 1: 2 to 20, preferably 1: 2 to 19, or the solution of glutinous glue is mixed with the lacquer in a ratio of 1: 20, and preferably from 1: 6 to 19. Since the quality and quality of the lacquer are decreased as the amount added to the lacquer is higher, it is preferable that the lacquer is mixed with 5-15% by weight of the lacquer and 5-30% by weight of the lacquer.

The present invention also provides a method for preserving artifacts comprising the step of applying a natural coating composition according to the present invention to an artifact. The natural coating composition according to the present invention has a suitable viscosity and can be dried under ordinary conditions of room temperature and relative humidity of 50 5%, and thus can be usefully used for preserving artifacts.

This peak is considered to be a peak near 1720 cm ^{- 1} indicating carbonyl (C = O) bond, and it is a peak that increases as curing proceeds due to bonding with oxygen. Therefore, as the addition rate of glue increased, the amount of carbonyl bond increased and the drying rate rapidly increased. Unlike the cured state of the lacquer and refinement coating near the carbonyl bond of the specimen in which the lacquer has been crosslinked, additional peaks can be identified. It appears that the concentration producing a protein peak found in a result of IR analysis of the NH eogyo glue bond of 1640cm ^-1 to 1540cm ^-1 are more clearly separated from the high tenets formulation.

< Experimental Example  6> Surface observation after drying of the compounded sample

The coated samples were applied to the coating samples and the drying time was measured. The surface of the completely dried coatings was observed using a stereomicroscope.

As a result, the surface of the coating film mixed with the lacquer was hardened smoothly irrespective of the type of lacquer, the production ratio of the lacquer, and the addition ratio. As a result of magnification observation with a stereoscopic microscope (see Fig. 3), the coating film of lacquer and lacquer had a relatively long curing time but had a characteristic of being hardened without wrinkling as applied. On the other hand, it was found that the coating film mixed with the fish paste on the fresh surface had some impurities mixed on the surface of the coating film, It is judged to be an impurity inside the fresh green.

The specimens mixed with lacquer and glue showed differences in the surface properties depending on the quality and refinement (see FIG. 4). In other words, the sample mixed with glue on the right side had a very long curing time at 5% but had well-cured properties without wrinkles, and 10 to 15% showed a rough surface with many wrinkles and impurities. However, the curing time was shorter in the refinish coat than in the fresh coat. The addition of glue showed shorter curing time and smooth surface condition in refinish coat than in fresh coat.

<Experimental Example 7> Analysis of chromaticity characteristics of the compounded sample

The natural paint composition prepared in Example <1-1> was applied to a coating film sample, and the color difference was measured using a portable colorimeter on the surface of the coating film after drying completely. Specifically, the apparatus used for chromaticity measurement was measured by using a portable colorimeter (BYK Gardner), and the color difference was measured. The measurement criterion was L ^* a ^* b ^* table coloring method in which L is a vertical axis and colors are represented by orthogonal coordinates a and b. L represents the brightness, and the higher the value, the higher the brightness. a and b each represent the saturation.

As a result, it was found that the mixture of fresh and mixed fishes had similar or slightly lower brightness value (L) than that of fresh fish, but it was not visually recognizable. Saturation a and b were slightly lower than those of fresh fish, (See Table 5). Refinement and crosslinking mixtures also had a similar brightness value to that of refined paint, and there was almost no difference in brightness, and saturation a and b were somewhat lower than those of refined paint, but there was no difference in chromaticity due to difficulty in visual recognition.

There was a slight difference in brightness between greenish and glutinous mixtures compared to fresh ones, but the change in saturation was less noticeable than the mixture of glycosides (see Table 6). In addition, the refinement and glue mixture showed almost similar brightness and saturation as the refinement, and there were no visual differences.

< Comparative Example  1> Fresh  And As a fish  And Tongue  Single character comparison

The viscosity of the natural coating composition of Example <1-1> was compared with the use of a water-soaked fish starch (gum: water = 1: 4) in the same manner as in Example <1-1>.

The natural coating compositions and Charismatic  compare sample Mixing ratio Viscosity( Pa .s) Fresh fish + fish (Kyou: water = 1: 4) 10% 1.64 Fresh fish + fish (Kyou: water = 1: 10) 10% 1.17 Kyo (school: water = 1: 4) - 0.23

As can be seen from Table 7, it can be seen that the viscosity of the natural paint composition blended with freshness and texture is remarkable as compared with the use of alone. In addition, as the ratio of water increased in the sole use of the fish, there was a cracking phenomenon (Kyo: water = 1:10). When the ratio of fish was increased, contraction and bowing occurred (Kyo: water = 1: 4 ), And natural creams and mixtures thereof.

< Comparative Example  2> Fresh  Comparison of the properties of a natural paint composition composed of glue and glue alone

The viscosity of the natural coating composition of Example <1-2> was compared with the use of glue alone (gum: water = 1: 4), which was immersed in water in the same manner as in Example <1-2> above.

Comparison of the natural coating compositions and glue of the present invention sample Glue mixture ratio Viscosity ( Pa . S ) Fresh green + glue (gyo: water = 1: 4) 15% 2.54 Fresh green + glue (gyo: water = 1: 10) 15% 1.89 Glue (gyo: water = 1: 4) - 0.09

As can be seen from the above Table 8, it can be seen that the viscosity of the natural paint composition blended with the sunscreen and glue is remarkably higher than that of the glue alone. Also, as in Comparative Example 1, when the ratio of water was increased in the use of glue alone, cracking occurred (Kyou: water = 1:10). When the ratio of glue increased, shrinkage and bending phenomenon appeared : Water = 1: 4), and the natural coating composition blended with sunshine and glue showed no such phenomenon.
