Method for reinforcing silicate cultural relics through hyperbranched polysiloxane and application
The invention discloses a method for reinforcing silicate cultural relics through hyperbranched polysiloxane and application. The hyperbranched polysiloxane takes a Si-O-Si chain as a skeleton, and has a chemical structure as shown in a formula I, wherein M and H are same or different functional end groups; and preferably, M and H are independently selected from one of hydroxyl, amino, epoxy group, methyl and methoxyl. According to the method and the application, the appearance of the silicate cultural relic reinforced by using hyperbranched polysiloxane is hardly changed, and compared with the traditional linear organic silicon material reinforcement, the silicate cultural relic reinforced by using the hyperbranched polysiloxane has a better reinforcement effect and particularly has high compressive strength, good storage stability and excellent air permeability.
本发明公开一种超支化聚硅氧烷加固硅酸盐质文物的方法和应用。所述超支化聚硅氧烷以Si‑O‑Si链为骨架，具有式I所述的化学结构：其中，M和H为相同或不同的功能性端基；优选地，M、H独立地选自羟基、氨基、环氧基、甲基、甲氧基中的一种。所述方法和应用使用超支化聚硅氧烷加固后的硅酸盐质文物外观几乎没有变化，相比传统的线性有机硅材料加固具有更好的加固效果，尤其是具有高抗压强度、良好的储存稳定性和优异的透气性。
