Problems solved by technology

Many civil air defense facilities are built with reinforced concrete. Since civil air defense projects are mostly built in underground environments, and the underground environment is usually poor in air permeability, humid and hot, it is easy to accelerate the aging speed of civil air defense facilities and reduce their corrosion resistance, especially for steel bars. Civil air defense facilities with concrete structures cause certain erosion, which leads to cracking of concrete properties and damage to the structure, failing to reach the expected life

Abstract

The invention provides a surface preservative for a civil air defense facility and a preparation method of the surface preservative. The surface preservative for the civil air defense facility is prepared from, by mass, 20-25 parts of rosin glyceride, 15-22 parts of polyurethane, 8-14 parts of modified nano diatomite in powder, 5-12 parts of micaceous iron oxide, 5-7 parts of sodium lauryl sulfate, 5-7 parts of titanium carbide, 5-7 parts of zirconium dioxide, 0.1-0.3 part of coupling agent, 0.2-0.3 part of adhesion promoters, 3-6 parts of pigments and 30-40 parts of water. The surface preservative for the civil air defense facility has the advantages of being good in acid, alkali, salt and gasoline corrosion resistance, resistant to freezing and melting, moisture, mildew, artificial climatic aging and the like, and capable of maintaining good weather resistance under various physicochemical erosion and effectively protecting the surface of the civil air defense facility.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a surface preservative for civil air defense facilities and a preparation method thereof. Background technique [0002] Civil defense is also known as civil defense. Civil defense is an international term. English CIVIL DEFENCE is an activity in which the government mobilizes and organizes the masses, adopts anti-airstrike, disaster relief measures, implements rescue operations, and prevents and mitigates disasters. Many civil air defense facilities are made of reinforced concrete. Since most civil air defense projects are built in underground environments, and the underground environment is usually poor in air permeability, humid and hot, it is easy to accelerate the aging speed of civil air defense facilities and reduce their corrosion resistance, especially for steel bars. Civil air defense facilities with concrete structures cause certain erosion, which ...
