- Abstract:
- The conservaney agent for historical bricks was prepared by using (3-glycidyloxypropyl) methyldie.thoxysilane, (3-aminopropyl) triethoxysilane, water, and HCl as reactants. The elfeet of reaetive formula oncure time and membrane performanee was investigated and the optimum fomula V( KH560 ): V(KH550 ): (H,0)=10: 1: 2.4,196 HCl) was obtained. The conservaney performanee of the oplimum formula was valuedon unearthened fragments of brick reliels. Through the comparision of some performanee parameter such as waterabsorplion, salt absorplion, thaw-freeze eycle, and salt resistanee before and after conservalion, it was foundthat the porousness and hydrophilieity of the bricks were still maintained and the thaw-freeze cyele and salt re.sistanee inereased about 2 times, meanwhile the strength and weather resistanee were enhaneed signifieanlly.
