Description
Technical Field
The invention relates to the technical field of cultural relics reinforcing agents, in particular to a ceramic colored drawing cultural relics reinforcing agent.
Background
Ceramic colored drawing cultural relics contain rich information such as science and technology, culture, customs, religious beliefs and the like in various periods of human development, so that the ceramic colored drawing cultural relics become an important component of Chinese civilization. When the ceramic colored drawing cultural relics are buried underground, the cultural relics are in a constant-temperature and constant-humidity, anoxic and light-resistant antibacterial environment, and after the cultural relics are unearthed, diseases such as warping, crisp powder, cracking and falling of the colored drawing layer can occur due to abrupt change of temperature and humidity, so that the ceramic colored drawing cultural relics are damaged.
Crisp powder is one of the most common diseases in ceramic colored drawing cultural relics, and the existence of soluble salt and micro-capacitive salt is one of the important reasons for causing salt damage. Because of the self void structure of the ceramic colored drawing cultural relics, the soluble salt and the slightly soluble salt are migrated into the void of the ceramic colored drawing cultural relics along with migration of groundwater, and the ceramic colored drawing cultural relics are in a high-humidity state of a deep underground layer before soil emergence, and the soluble salt and the slightly soluble salt are in a dissolved state all the time. After the ceramic colored drawing cultural relics are unearthed, the process of 'dissolving-crystallizing-dissolving' repeated circulation of soluble salt and slightly soluble salt in the ceramic colored drawing cultural relics occurs along with the change of the external temperature and humidity, and the salt can generate crystallization pressure in the crystallization process, so that the physical structure and the mechanical property of the ceramic colored drawing cultural relics with a void structure are changed, and finally the crisp powder disease is caused. The crisp powder can seriously damage the original appearance of the ceramic colored drawing cultural relics, endanger to destroy, and even disappear forever. Therefore, the reinforcing agent with water and salt permeable functions is necessary to be used for curing the colored drawing layer and the ceramic tire of the surface crisp powder of the ceramic colored drawing cultural relics.
Patent CN 103992729 discloses a crisp ceramic colored drawing cultural relic reinforcing agent, which is prepared by dissolving ADM-Z719 aqueous polyurethane resin, ZB-F600 two-component FEVE aqueous fluororesin and water-soluble epoxy resin B-63 in distilled water, dissolving C8-10 fatty alcohol polyoxyethylene ether JFC-6 in ethanol, and then uniformly mixing with methanol. However, in the crisp ceramic colored drawing cultural relic reinforcing agent of patent CN 103992729, methanol and ethanol account for more than 70% of the composition of the raw materials, methanol is easy to volatilize in use, and the reinforcing agent is inflammable, so that the cultural relic has the hidden trouble of ignition and damage.

In order to prove the beneficial effects of the invention, the inventor tests the transmittance of the ceramic colored cultural relic reinforcing agent after film formation, adopts the ceramic colored cultural relic reinforcing agent prepared in the embodiment 1 to reinforce a ceramic colored simulation sample, and performs various characterizations on the sample before and after reinforcement, and the specific conditions are as follows:
1. transmittance of reinforcing agent after film formation
The reinforcing agent was put into a Lambda9500 ultraviolet near infrared spectrophotometer after film formation for transmittance test, and the result is shown in fig. 1. The transmissivity of the reinforcing agent in the visible light range of 390-800 nm after film formation is 91.96%, which indicates that the reinforcing agent has better transparency after film formation, and the appearance of the reinforced cultural relics can not be covered by the reinforcing agent.
2. Reflectivity analysis before and after reinforcement of ceramic colored drawing simulation sample
And uniformly smearing the stone green on the fired ceramic blocks to serve as a ceramic colored drawing simulation sample. The ceramic colored drawing simulation sample is reinforced by the reinforcing agent, and the reflectivity of the ceramic colored drawing simulation sample before and after reinforcement is tested by a Lambda950 ultraviolet near infrared spectrophotometer, and the result is shown in figure 2. As can be seen from fig. 2, the reflectivity of the ceramic colored drawing simulation sample before and after reinforcement is almost similar, which indicates that the reinforcing agent does not substantially change the appearance of the cultural relics and does not affect the appearance of the cultural relics.
3. Microcosmic morphology change before and after reinforcement of ceramic colored drawing simulation sample
The microscopic morphology of the ceramic colored drawing simulation sample before and after reinforcement is tested by using an SU3500 tungsten filament scanning electron microscope, the microscopic morphology before reinforcement is shown in fig. 3, and the microscopic morphology after reinforcement is shown in fig. 4. As can be seen from fig. 3, the surface of the non-reinforced ceramic colored drawing simulation sample is loose particles and has more cracks; as can be seen from fig. 4, the cracks on the surface of the sample simulated by the ceramic colored drawing after reinforcement are filled with the reinforcing agent, and the reinforcing agent forms a film on the surface of the sample, so that loose particles on the surface of the sample are wrapped inside, the microscopic morphology is greatly improved, and the excellent reinforcing effect is achieved. The ZB-F600 double-component FEVE aqueous fluororesin in the reinforcing agent has good film forming property, the S-1430B silica sol has good dispersibility and strong permeability, and the reinforcing agent has good film forming property, adhesiveness and permeability after being mixed with poly (2-ethyl-2-oxazoline), so that the microscopic morphology of the surface of the colored drawing simulation sample is greatly improved.
4. Color difference change before and after reinforcement of ceramic colored drawing simulation sample
The ultraviolet aging and freeze thawing aging test is carried out on ceramic colored drawing simulation samples before and after reinforcement, and the specific test method comprises the following steps:
ultraviolet aging: respectively placing ceramic colored drawing simulation samples before and after reinforcement into an ultraviolet aging test box, setting the ultraviolet power to be 60W, the vertical irradiation distance to be 5cm, and the aging time to be 72 hours;
freezing, thawing and aging: and respectively placing ceramic colored drawing simulation samples before and after reinforcement into a freeze thawing test box, setting the high temperature to 40 ℃ and the low temperature to-40 ℃ and 12 hours as one cycle, and carrying out six-cycle test.
The X-RiteVS-450 spectrophotometer is adopted to carry out color difference test on the ceramic colored drawing simulation samples before and after the reinforcement without aging, the ceramic colored drawing simulation samples before and after the reinforcement with ultraviolet aging and the ceramic colored drawing simulation samples before and after the reinforcement with freeze thawing aging respectively, and the test results are shown in Table 1.
TABLE 1 color difference values before and after reinforcement aging of ceramic colored drawing simulation samples
As can be seen from Table 1, the color difference of the simulation samples before and after the reinforcement aging is less than 5, and the color difference is slight in color change, which indicates that the reinforcement agent has small influence on the color of the ceramic colored drawing cultural relics. The silica sol in the reinforcing agent is nano SiO 2 Colloidal dispersion of (2) nano SiO 2 The particles are colorless and transparent, have better dispersibility and transparency, and do not influence the natural color of the ceramic colored drawing cultural relics.
5. Contact angle test before and after reinforcement of ceramic colored drawing simulation sample
The ceramic color painting simulation samples before and after reinforcement were tested for hydrophilicity and hydrophobicity by using an HRUSS-DSA100 optical contact angle measuring instrument, and the test results are shown in Table 2.
TABLE 2 contact angle of ceramic colored drawing simulation sample before and after reinforcement
The results show that the average contact angle of the simulation sample before reinforcement is 66.7 degrees, the average contact angle of the simulation sample after reinforcement is 85.1 degrees, and the hydrophobicity of the ceramic colored drawing simulation sample is greatly improved. The improved hydrophobicity is beneficial to the subsequent desalination of the ceramic colored drawing simulation sample, and damage to the crisp powder cultural relics during desalination is reduced.
In the reinforcing agent of example 1, the ZB-F600 two-component FEVE aqueous fluororesin increases the hydrophobicity of the reinforcing agent. The silica sol has good dispersibility and extremely strong permeability, and the poly (2-ethyl-2-oxazoline) can improve the flexibility and the permeability of the reinforcing agent, so that the ZB-F600 two-component FEVE aqueous fluororesin has a synergistic effect under the condition that the silica sol and the poly (2-ethyl-2-oxazoline) exist, and the dispersibility and the permeability are higher than those of the ZB-F600 two-component FEVE aqueous fluororesin which exists alone and the ZB-F600 two-component FEVE aqueous fluororesin which is mixed with other components. Therefore, the contact angle after reinforcement can reach 87.2 degrees at most, and the average contact angle reaches 85.1 degrees. By contrast, the reinforcing agent prepared in patent CN 103992729B had a contact angle of 82.5 ° which was significantly lower than that of the reinforcing agent of example 1.
6. Ceramic colored drawing simulation sample adhesion change before and after reinforcement
The adhesion test was performed on ceramic colored drawing simulation samples before and after reinforcement aging according to GB/T5210-2006 adhesion test by the paint and varnish pull-off method, and the test results are shown in Table 3.
TABLE 3 adhesion of ceramic colored drawing simulation samples before and after reinforcement aging
In GB/T5210-2006 adhesive force grade of the adhesive force test of the color paint and varnish pulling-off method, the grade C is worse, and the grade A is best. Under the three conditions of unaged ceramic colored drawing simulation samples, namely unaged ceramic colored drawing simulation samples, freeze thawing aging ceramic colored drawing simulation samples and ultraviolet aging ceramic colored drawing simulation samples, the adhesion of the ceramic colored drawing simulation samples is C grade, and the adhesion is poor; the adhesive force of the reinforced ceramic colored drawing simulation sample before and after aging is A grade, the adhesive force is good, the breaking strength is 2.27-3.06MPa, and the reinforcing effect and the aging resistance of the reinforcing agent are obvious.
