Abstract

The invention discloses a water-based carbonizing resistance coating which is prepared from, by weight, 27-29 parts of deionized water, 10-12 parts of dispersing and wetting agents, 354-356 parts of fillers, 549-551 parts of special modified acrylic resin, 10-11 parts of water repellent agents, 40-41 parts of functional auxiliaries and 4.1-4.3 parts of sterilizing preservatives. The water-based carbonizing resistance coating has excellent weather resistance, chalking resistance, stain resistance, alkali resistance, acid rain resistance, water resistance and scrub resistance. Owing to unique normal-temperature curing self-crosslinking performance, additional crosslinking agents and high-temperature baking are omitted, mass production is facilitated, and the coating is simple in process, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of anti-carbonization coating materials for building facades, in particular to a water-based anti-carbonization coating. Background technique [0002] Concrete carbonation refers to the reaction in which CO2 in humid air diffuses into concrete and reacts with calcium hydroxide to form calcium carbonate, also known as carbonation. Carbonation in a broad sense is also called neutralization: anything that can be neutralized with Ca(OH)2 All acidic gases such as SO2, SO3, H2S and even gas phase HCL, etc., can carry out the above neutralization reaction and reduce the alkalinity of concrete. [0003] The carbonization protective agent is applied on the surface of concrete, masonry and other structures, penetrates and diffuses into the structure, blocks the water passage, and plays an ideal waterproof role. At the same time, it can also protect the structure from the erosion of acid, alkali, various types of oil,...
