[0007] The patent with the application number 201010299679.0 titled "A Two-Component Environmental-Friendly Inorganic Polymer Coating Material and Its Preparation Method" is a typical formula of alkali-activated inorganic polymer materials. Since alkali-activated inorganic polymer materials are Hydrophilic materials will produce a large number of penetrating capillary pores during the hardening process, forming channels for water penetration, so the coating cannot block the invasion of water. From the test point of view, it is even inferior to cement-based materials. Body protection is poor
The accumulation of moisture inside the coating has several hazards: one is that the protected structure will be attacked by water, and the durability will be reduced; Lose

Embodiment 1

[0066] 45 grams of potassium silicate solution (concentration 30%, modulus 2.0), 2.5 grams of sodium hydroxide, 20 grams of metakaolin, 25 grams of slag, 6 grams of mica powder, 3 grams of chopped glass fiber, 2 grams of methyl silicate Potassium solution (content 20%), 0.02 grams of sodium borate, 3 grams of redispersible latex powder.

[0067] The above proportions can be packed in two components, and component A includes potassium silicate solution and potassium methyl silicate solution. The rest is B component.

[0068] The above coating can be used as a protective coating for concrete surfaces, and is especially suitable for surface protection of bridges and tunnels.

Embodiment 2

[0070] 42 grams of lithium silicate solution (concentration 30%, modulus 2.0), 3.2 grams of sodium carbonate, 10 grams of metakaolin, 15 grams of slag, 5 grams of fly ash, 6 grams of mica powder, 5 grams of glass fiber cloth, 2 grams Silicone water repellent, 0.03g citric acid, 0.02g sodium borate, 10g redispersible latex powder, 3g calcium carbonate, 2g aluminum hydroxide.

[0071] The above ratio can be packaged in three components, and component A includes: lithium silicate solution, silicone water repellent, sodium carbonate, and sodium borate. B components are: glass fiber cloth, and the rest are C components.

[0072] Mix component A and component C before construction, and start construction after aging for 1 hour. During construction, stick glass fiber cloth on the painted surface, which can effectively prevent cracking of the coating.

[0073] The above-mentioned paint can be used as a protective paint on the wall, and can also be used for repairing concrete, because...

Abstract

The invention relates to a hydrophobic modified alkali-activated inorganic polymer coating restoration material, and belongs to the field of building materials. The hydrophobic modified alkali-activated inorganic polymer coating restoration material is used for the surface restoration and protection of building engineering, and is especially suitable for the restoration and protection of concrete of walls, water conservancy engineering, tunnels, bridges, roads, docks and water pools. The hydrophobic modified alkali-activated inorganic polymer coating restoration material comprises water, an alkali activator, a gelling base material, a water repellent and an assistant.

Description

technical field [0001] The invention relates to a hydrophobic modified alkali-excited inorganic polymer coating repair material, which is used for surface repair and protection of construction projects, and is especially suitable for concrete repair of walls, water conservancy projects, tunnels, bridges, roads, wharves and pools And protection, belonging to the field of building materials. Background technique [0002] Geopolymer cement is a new type of alkali-excited cementitious material developed by French J. Davidovits in the late 1970s. formed under the action of the agent. The silica-alumina oxy-compounds in the minerals of geopolymeric cement raw materials have undergone a process from depolymerization to repolymerization, forming a structure similar to some natural minerals in the earth's crust, which is a new type of cementitious material with excellent durability. Many minerals or mineral mixtures have pozzolanic activity or latent hydraulic properties after high...
