Problems solved by technology

With the development of global industrialization, carbon dioxide, nitrogen dioxide and other substances in the atmosphere continue to increase, resulting in increasing acidity in rainwater. The currently known acid rain pollution can cause damage to the ecological environment, human health, building materials, etc. In particular, acid rain can cause accelerated corrosion and aging of buildings, causing huge economic losses. The concrete exterior walls of buildings will expand and contract with changes in ambient temperature. Cracking, and under the condition of acid rain, the surface coating of the concrete exterior wall building is easily corroded by acid rain, resulting in discoloration of the coating, reduced adhesion, blistering, peeling and other disadvantages

Description

technical field [0001] The invention relates to the technical field of acrylic exterior wall paint, in particular to an acid rain-resistant acrylic exterior wall paint. Background technique [0002] Acid rain is mainly caused by human production activities and life, and the harm to human beings will also increase day by day. With the development of global industrialization, carbon dioxide, nitrogen dioxide and other substances in the atmosphere continue to increase, resulting in increasing acidity in rainwater. The currently known acid rain pollution can cause damage to the ecological environment, human health, building materials, etc. In particular, acid rain can cause accelerated corrosion and aging of buildings, causing huge economic losses. The concrete exterior walls of buildings will expand and contract with changes in ambient temperature. Cracking, and under acid rain conditions, the surface coatings of concrete exterior walls are easily corroded by acid rain, result...
