Abstract

The invention discloses a weather-proof self-cleaning copper gold lacquer which comprises a component A and a component B, wherein the ratio of the component A to the component B in parts by weight is (10-12.5):1, the component A comprises 65-75wt% of resin solution, 15-25wt% of bronze powder, 5-10wt% of solvent, 2-5wt% of dispersing agent, 1-3wt% of defoaming agent and 1-3 wt% of ultraviolet absorbent; and the component B comprises the ingredients of 50-90 wt% of curing agent and 10-50wt% of solvent. The invention also discloses a preparation method of the weather-proof self-cleaning copper gold lacquer. During the use, the component A and the component B are mixed uniformly according to a proportion and are cured so that coating construction can be carried out. The weather-proof self-cleaning copper gold lacquer related in the invention can be used in protection and appearance decoration of outdoor buildings, sculptures and the like, has a long-term gold color and a metal texture, does not need to be frequently cleaned in a coating service process so that manpower and material resources are saved, and provides the convenience for corrosion-prevention and decoration industries.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a weather-resistant self-cleaning copper-gold paint and a preparation method thereof. Background technique [0002] At present, when carrying out gold decoration treatment on small items such as plaques and handicrafts, most of them adopt gold paste or gold plating treatment processes, which are either expensive or unsuitable for outdoor construction. Therefore, the golden lacquer treatment process is mostly used for the gold decoration treatment of large buildings and outdoor statues. The advantage of this process is that it is convenient for construction and relatively cheap in cost. However, gold lacquer also has poor metal texture and is prone to uneven discoloration under light. , loss of light and other shortcomings, in addition, under the action of rain and polluting gases, ordinary gold paint is easy to form stains, affecting the look and feel.
