Abstract

The invention provides a water-based anti-carbonization coating and a preparation method thereof. Mass percent, the water-based anti-carbonization coating comprises the following components: 30 to 40%of fluorocarbon emulsion, 10 to 15% of a carbonization inhibitor; 0.3 to 0.5% of a film forming auxiliary agent; 0.3 to 0.5% of an ultraviolet light absorber, 0.5 to 1% of an anti-freezing agent, 0.5to 0.8% of a dispersing agent, 0.1 to 0.2% of a wetting agent, 0.3 to 0.5% of a defoaming agent, 0.2 to 0.3% of a pH regulator, 0.2 to 0.6% of a preservative, 20 to 25% of pigment and filler, 0.2 to0.5% of a thickening agent and 20 to 30% of water. And the coating has excellent weather resistance, corrosion resistance, low temperature resistance, ultraviolet resistance and the like.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a water-based anti-carbonization coating and a preparation method thereof. Background technique [0002] Concrete structure is one of the most widely used structures. In my country, 70% of house construction and 50% of bridge structures use concrete structure. With the increase of the service time of these engineering structures, more and more attention has been paid to the durability damage of concrete materials and structures. Many engineering structures often cause functional degradation or even structural damage due to durability, which brings unnecessary costs to the society. loss. [0003] Concrete carbonation is one of the important durability indicators of concrete. Calcium hydroxide will be generated after the cement of the mixed concrete is hydrated. Most of the calcium hydroxide exists in the concrete in a crystalline state and becomes a reserve for the interstiti...
