Abstract
The invention discloses painted clay sculpture in a kind of ancient times to gild surface contaminant abluent, this abluent is by deionized water, ammonium citrate, dehydrated alcohol is mixed, gained abluent is nontoxic, cleaning performance is good, cleaning process is to native gold not damaged, can effectively remove clay sculpture to gild the pollutant on surface, pollutant clearance rate is up to more than 95%, especially for having ftractureed, fragile surface of gilding, the native gold under it is not destroyed while removing surface contaminant of gilding, because cleaning process need not manual intervention, only need to constantly change the purpose that adsorbing material rice paper (raw a surname) i.e. reaches to clean.
Description
Technical field
The present invention relates to painted clay sculpture in ancient times surface gild the cleaning of pollutant, specifically tradition is gilded technique native gold table
The removal of the gold lacquer that face is weathered.
Background technology
Gild is that one of long traditional decoration technique is spread in China.It is with the coating being rich in caking property, such as the system of tempering
The boiled wood oil (being commonly called as gold size) obtained, pastes metal or nonmetal implements, building, leatherware, paper and weaving by native gold
The surface of product, to increase exterior decorative effect.The main material gilded is native gold, and ancient times, native gold was called " gold is thin ".Tang and Song Dynasty time
The heavy construction that method is later age that heap mud or heap powder are gilded occur, the construction such as palace temple and woodcarving, the clay sculpture figure of buddha rises
Particularly important effect.China's Dunhuang, Gansu Province Mogao Grottoes, sky and water Maiji mountain, Huayan Temple, Datong, Shuanglin Temple, Pingyao etc., all
There is the substantial amounts of painted sculptures figure of buddha of gilding.Gilding painted sculptures, i.e. in addition to face, extremity, first one layer of Resina Toxicodendri verniciflui of brush on clay sculpture, waits to paint ninety percent dry
Time, stick native gold successively, the most again at one layer of gold lacquer of native gold face cap.But due to of the remote past, the surface gold at position of gilding
Paint the many factors such as aging, surface laying dust make to gild area discoloration, ftracture, warp, owing to native gold is relatively thin, as light as a feather, Bao Ru
Cicada's wings, thickness is less than 0.12 micron, and after surface gold lacquer is aging, native gold is torn into the fritter differed in size by cracking, carries out at clay sculpture
Needing before Conservative restoration to clean out gold lacquer weathered for surface of gilding, historical relic's protection is repaired in specification and is defined as table
Surface pollution thing.
Being presently mainly the pollutant using mechanical means i.e. to reject surface of gilding with bamboo let, the method is difficult to clean up totally
Gild the pollutant on surface, and fragile native gold can be caused secondary damage.Cleaning conventional during historical relic's protection
Agent has dehydrated alcohol, acetone, or any one mixture in deionized water and dehydrated alcohol, acetone, and mentioned reagent is independent
Or compounding use is limited to the dissolving power of aging gold lacquer, it is necessary to artificial mechanical removes and could remove, and due to native gold and lacquer
In conjunction with very firm, secondary certainly will be caused to destroy native gold, therefore many native golds preserve the historical relic differed from and have to use and again paste
The method of gold.And using the conventional organic solvents such as ethyl acetate, petroleum ether, Oleum Terebinthinae, chloroform, aging paint film is the most insoluble, clearly
Wash effect excessively poor.
Summary of the invention
The technical problem to be solved is to overcome existing painted clay sculpture in ancient times surface to gild pollutant cleaning side
The shortcoming that method exists, it is provided that one easily operates, nontoxic, cleaning performance good and cleaning process abluent undamaged to native gold.
Solve above-mentioned technical problem and be employed technical scheme comprise that this abluent is made up of the raw material of following proportion by weight:
Deionized water 100 parts
Ammonium citrate 5～12 parts
Dehydrated alcohol 60～150 parts.
Above-mentioned painted clay sculpture in ancient times surface contaminant abluent of gilding preferably is made up of the raw material of following proportion by weight:
Deionized water 100 parts
Ammonium citrate 6～10 parts
Dehydrated alcohol 100～140 parts.
Above-mentioned painted clay sculpture in ancient times surface contaminant abluent of gilding most preferably is made up of the raw material of following proportion by weight:
Deionized water 100 parts
Ammonium citrate 8 parts
Dehydrated alcohol 134 parts.
The gild preparation method of cleaning agent for pollutant of present invention painted clay sculpture in ancient times surface is: according to the quality of above-mentioned raw materials
Per distribution ratio, is dissolved completely in ammonium citrate in deionized water, is subsequently adding dehydrated alcohol, stirs to solution achromaticity and clarification,
I.e. can get painted clay sculpture in ancient times surface to gild cleaning agent for pollutant.
The gild using method of cleaning agent for pollutant of present invention painted clay sculpture in ancient times surface is: takes the abluent prepared and uses
Wool brush is coated in surface of gilding uniformly, and after 30 seconds, aging gold lacquer i.e. softens dissolving, and then life rice paper stick on place of gilding, and 10
Removing rice paper after Miao, repeat above step, until surface aging gold lacquer is all removed, rice paper sticks appropriate to the occasion banister brush and gently sweeps,
Must not press...with one's finger and touch, with antisitic defect native gold.
Historical relic non-renewable determines the minimum of interference during historical relic's protection, and the present invention is according to table of gilding at present
The shortcoming that face is cleaned, compounds dehydrated alcohol, ammonium citrate and deionized water, and the pH value of the compounding abluent obtained is 7.5 left sides
The right side, uses this abluent the most aging gold lacquer in surface of first being gilded by the figure of buddha to dissolve, and repeatedly changes suction with raw rice paper after dissolving
The attached purpose that i.e. can reach cleaning, cleaning process reaches more than 95% to native gold not damaged, surface contaminant clearance rate.
Abluent of the present invention is nontoxic, cleaning performance good, especially for having ftractureed, fragile surface of gilding, is removing
Do not destroy the native gold under it while aging gold lacquer, because cleaning process need not manual intervention, only need to constantly change enclosure material
Rice paper (raw a surname) i.e. can reach the purpose of cleaning.
