Abstract

The invention discloses an automatic cleaning finish for exterior walls, and a preparation method thereof. The finish comprises, by weight, 30-60 parts of water, 0.1-0.5 parts of an antifoaming agent, 0.4-1.2 parts of an antifreeze agent, 30-60 parts of an emulsion, 0.8-2.0 parts of a film forming assistant, 0.1-0.4 parts of an antiseptic and 0.01-0.5 parts of an antistatic agent. The preparation method comprises the following steps: weighing above finish components according to above weight proportions; adding water to a finish preparation kettle; sequentially adding the emulsion, the antifoaming agent, the antifreeze agent and the film forming assistant while stirring; uniformly stirring above added components, and adding the antiseptic and the antistatic agent; and stirring above obtained components until uniformity to obtain the finished finish. The finish has exterior wall protection and decoration effects, has the advantages of excellent stain resistance, weatherability, low surface energy, high antistatic property and high light transmittance, can realize automatic cleaning of building exterior walls by using wind and rainwater in natural environment, solves the problems of easy pollution, easy efflorescence, color change and spalling of surfaces of buildings, and prolongs the service life of building exterior wall coatings.

Description

technical field [0001] The invention relates to the field of finish paint for exterior walls, in particular to a self-cleaning finish paint for exterior walls and a preparation method thereof. Background technique [0002] In recent years, building exterior wall coatings have been widely used in the decoration and beautification of building exterior walls due to their bright colors, convenient construction, and excellent decorative effects. Damaged by natural factors such as wind, sand and dust, and affected by environmental pollution, heavy metal particles and other suspended dust haze in the atmosphere will be more adsorbed and deposited on the paint coating with strong decorative texture and rough and uneven surface On the surface, it catalyzes and accelerates the pulverization, discoloration and peeling of the exterior wall paint coating, which affects the visual aesthetics and comfort of the overall exterior wall of the building. Therefore, sand wall texture coatings, ...
