Problems solved by technology

Due to the complicated repair process and long construction period, it is best to complete the repair work at one time. In order to avoid the long-term erosion of rainwater and cause multiple repairs in the later stage, it is best to use water-resistant and environmentally friendly water-based paint, but it is currently used in ancient buildings. The water resistance and environmental performance of the repaired water-based paint are not too high, therefore, a new paint needs to be provided

Abstract

The invention discloses a water-resistant environment-friendly waterborne coating. The water-resistant environment-friendly waterborne coating comprises, by weight, 90-110 parts of modified polyurethane emulsion, 15-20 parts of pigment, 13-15 parts of filler, 2-4 parts of C-12 alcohol ester, 2-4 parts of tristearin, 0.2-0.4 part of flatting agent, 0.03-0.05 part of antifoaming agent, 0.1-0.3 part of wetting agent, 0.4-0.6 part of hydroxyethyl cellulose, 0.8-1 part of vinyl trimethoxy silane,0.2-0.4 part of mildew preventive and 10-15 parts of water. The water-resistant environment-friendly waterborne coating has the advantages of high resistance to water and corrosion, environmental friendliness and excellent anti-ultraviolet performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-resistant and environment-friendly water-based coating. Background technique [0002] Ancient buildings have extremely high historical, scientific and artistic value. If they are destroyed, they cannot exist anymore; and ancient buildings are old and will inevitably be damaged by nature or man-made. Therefore, we need to repair and maintain ancient buildings . Coatings are often used in the process of repairing ancient building rooms, door walls, inner and outer eaves, palms, floors, and walls. Due to the complicated repair process and long construction period, it is best to complete the repair work at one time. In order to avoid the long-term erosion of rainwater and cause multiple repairs in the later stage, it is best to use water-resistant and environmentally friendly water-based paint, but it is currently used in ancient buildings. The water resistance and environ...
