Problems solved by technology

Currently known acid rain pollution has caused damage to the ecological environment, human health, building materials, etc., especially acid rain can cause accelerated corrosion and aging of buildings, resulting in huge economic losses
[0004] On the other hand, the concrete exterior wall of the building will expand and contract with the change of the ambient temperature. This thermal expansion and contraction will cause the surface coating of the building to crack easily. The surface coating is easily corroded by acid rain, resulting in discoloration of the coating, reduced adhesion, blistering, peeling and other disadvantages
The existing building surface coating materials, on the one hand, do not have a good barrier and mitigation effect on the corrosion of acid rain; on the other hand, the temperature resistance is not good, and it is easy to crack and fall off under the change of temperature difference

Abstract

The invention discloses an acid rain corrosion resistant exterior wall paint. The exterior wall paint is composed of the following components: a main paint containing 40.0-55.0% of hydroxyl acrylic resin, 0.1-0.8% of a dispersing agent, 0.1-0.8% of a flatting agent, 0.1-1.0% of a defoaming agent, 0.1-1.0% of a foam removal agent, 0.01-25.0% of titanium dioxide, 10.0-40.0% of a filler, 0.5-2.0% of an anti-settling agent, 2.0-10.0% of xylene and 2.0-10.0% of high boiling point DBE; a curing agent containing 30.0-55.0% of an isocyanic acid vinegar curing agent, 10.0-30.0% of xylene and 10.0-50.0% of butyl acetate; and a diluent containing 10.0-90.0% of xylene and 10-90% of butyl acetate. A construction ratio of main paint to curing agent to diluent is 100:20:20. The exterior wall paint provided by the invention can reduce and mitigate damages on external walls of buildings due to acid rain and cracking of concrete wall.

Description

technical field [0001] The invention relates to a coating for building exterior walls, in particular to an acid rain-resistant polyurethane exterior wall paint suitable for protecting and decorating the surface of concrete building exterior walls in acid rain areas. Background technique [0002] With the development of global industrialization, the carbon dioxide, nitrogen dioxide and other substances in the atmosphere continue to increase, resulting in the continuous increase of acidity in rainwater, forming acid rain. Acid rain refers to atmospheric precipitation such as rain, freezing rain, snow, hail, and dew with a pH value between 4.3 and 5.6. Carbon dioxide and nitrogen dioxide in the atmosphere are the main substances that form acid rain. Among the components of acid rain, sulfuric acid accounts for 60%, nitric acid accounts for 32%, hydrochloric acid accounts for 6%, and the rest is carbonic acid and a small amount of organic acids. [0003] Acid rain is mainly cau...
