Abstract

The invention relates to an adhesive reinforcing agent for a building inorganic coating material and a preparation method of the adhesive reinforcing agent. The adhesive reinforcing agent for the building inorganic coating material is prepared by mixing a permeable reactive component, an inorganic dense component, a polymer-modified component, a nano-reinforced component, a surface tension-reducing component and a coupling agent component. By the adhesive reinforcing agent, the property of the interface between a cement-based composite material and the inorganic coating material can be effectively improved, the acting force of a surface-active substance and the surface of the cement-based composite material is significantly increased and by the preparation method, the environment-friendly building inorganic coating material which has the advantages of high density and high adhesion is prepared.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a bonding enhancer of an inorganic coating material for building and a preparation method thereof. Background technique [0002] Concrete and reinforced concrete structures are often vulnerable to the intrusion of aggressive media due to the porous structure of the concrete itself (CO 2 , Cl - , SO 2- etc.), corrosion is very common, and the corrosion damage of concrete structures has attracted more and more attention. Coating protection is a simple and efficient protective measure, which can improve the durability of concrete by coating a certain material to form a protective layer on the surface of concrete that can prevent water-soluble media from entering the interior of the concrete. Coating protection technology has become increasingly mature, and new materials and technologies are constantly emerging, which provide new ideas for the corrosion prot...
