Abstract

The invention discloses highly-elastic waterproof coating used for a metal roof. The coating is prepared by adding propylene glycol, powder, a filling material and other auxiliary agents into pure acrylic acid emulsion adopted as the base. The coating comprises the following materials by weight: 30-60 parts of the pure acrylic acid emulsion, 1-3 parts of the propylene glycol, 30-50 parts of the powder, 1-5 parts of the filling material and 0.1-4 parts of the auxiliary agents. The coating has an integral protection function for the metal roof so as to prevent water leakage. In addition, integral construction of the roof makes the coating whitened and the coating has certain reflection effects for solar heat and ultraviolet ray, thus playing a function of energy conservation.

Description

technical field [0001] The invention discloses a high-elastic waterproof coating for metal roofs, which belongs to the technical field of construction engineering protection. Background technique [0002] With the rapid development of my country's economy, steel structure buildings are widely used in machinery due to their light weight, high strength, good plasticity and toughness, superior seismic performance, high degree of industrial assembly, significant comprehensive economic benefits, and environmental protection. , light industry, textile, clothing, chemical industry, warehousing and logistics industries, as well as industrial and civil buildings such as commerce. [0003] Leakage of steel structure metal roof is also an indisputable fact. Although roof leakage will not immediately cause a major building accident, it will seriously affect the function of the building and potentially affect the service life of the building. It is understood that it is not uncommon for...
