Description
Technical field
The present invention relates to industrial coating technical field, it is related to using Thief zone concrete protection coating to solve existing coagulation
Native coating protection and the poor technical problem of permeability resistance, specifically, be it is a kind of there is high osmosis, can reinforced concrete knot
Structure, the cement-based penetrant type Polyaspartic Ester-Based Coatings simultaneously with good weather resistance and anti-fouling performance.
Background technique
China's industrialization and urbanization construction iterative method have developed rapidly, in recent years, urban water conservancy construction, underground structure
And domestic waste, industrial refuse problem have been to be concerned by more and more people.The engineering in general of the above-mentioned type belongs to extraordinary work
Journey, they are very high to the anti-corrosion waterproof requirement of concrete, thus need it is a kind of can reinforce concrete structure binding force and
The coating for having water-proof function and impermeable function protects the structure of engineering.In the construction of above-mentioned engineering, as can having
Effect ground, which improves concrete density, also can inherently solve the problems, such as the waterproof and anticorrosion anticracking of structure.And currently, conventional
Epoxy coating (epoxy resin paint film) can reinforce the protection to the concrete, still, the epoxy coating to a certain extent
Over time can gradually dusting and cause protective performance to reduce；And the high polyurethane resin of weatherability due to molecular weight compared with
Greatly, and the combination of concrete is weaker, and the resistance to concrete alkalinity performance of its paint film is bad, therefore, the high polyurethane tree of weatherability
Rouge is also more difficult directly to be applied on concrete.Polyaspartic ester is a kind of novel weather resistant materials, it has good
Toughness and mechanical performance, meanwhile, its own molecular weight is smaller, good penetrability, and alkaline resistance properties might as well；Therefore, people incite somebody to action in research
It is assisted as matrix resin, then using other high osmosis and corresponding high barrier material, it is applied to concrete
Protection.
Summary of the invention
