Abstract

The disclosed acrylate-organosilicon -epoxy resin is prepared by butyl acrylate, hydroxyethyl beta-methacrylate, maleic acid, KH570 and KH550, ethyl silicate, and epoxy resin E44; wherein, is applies ethyl acetate as solvent, azo-bis-iso-butyronitrile as initiator, and selects free radical copolymerization and sol-gel method. This organic/inorganic hybridized material has well transparency and thermal stability and fit to site protection.

Description

1. Technical field [0001] The invention relates to butyl acrylate, β-hydroxyethyl methacrylate, maleic anhydride, silane coupling agents KH570 and KH550, tetraethyl orthosilicate, epoxy resin E44 as basic raw materials, and ethyl acetate as solvent 1. Azobisisobutyronitrile is used as an initiator, and an acrylate-organosilicon-epoxy resin organic / inorganic hybrid material is synthesized by free radical solution copolymerization and sol-gel method, which belongs to the field of composite materials. The acrylate-organic silicon-epoxy resin organic / inorganic hybrid material prepared by the invention is suitable for reinforcement and protection of the surface layer of earthen ruins in a humid environment. 2. Technical background [0002] The use of chemical materials to reinforce and protect the surface of earthen sites is an important means to prevent the weathering of earthen sites [Zhou Shuanglin, Yuan Sixun. Preparation of non-aqueous dispersion of organosilicon-modified ac...
