Anti-aging luminescent inorganic coating for building exterior wall and preparation method thereof

Abstract

The invention discloses an anti-aging luminescent inorganic coating for building exterior walls and a preparation method thereof. According to parts by mass, the anti-aging luminescent inorganic coating for building exterior walls comprises the following raw materials: 20-30 parts of ceramic powder, 10-30 parts of modified epoxy resin 15 parts, 5-10 parts of hydroxyl silicone oil, 5-15 parts of luminescent powder, 10-15 parts of glass powder, 8.2-20.1 parts of mixing aid and 20-40 parts of water; the raw materials of modified epoxy resin include epoxy resin and A polyoxyethylene alkylphenol condensate, and according to the mass ratio, the mixing ratio of the epoxy resin and the polyoxyethylene alkylphenol condensate is (1.5-3):1. The anti-aging luminescent inorganic coating for building exterior walls proposed in this technical solution improves and optimizes the formulation of the luminescent coating, which helps to improve the anti-aging performance of the coating on the premise of ensuring the luminous effect of the coating. Furthermore, a preparation method of an anti-aging luminescent inorganic paint for building exterior walls is proposed, which has simple steps and strong operability, so as to overcome the shortcomings in the prior art.

Description

technical field [0001] The invention relates to the technical field of luminescent coatings, in particular to an anti-aging luminescent inorganic coating for building exterior walls and a preparation method thereof. Background technique [0002] Traditional coatings can be used as a decorative material for exterior walls and interiors of buildings, and can also play a role in waterproof protection on the exterior surfaces of buildings. [0003] In the field of architecture, the creation of artistic effects of building appearance through changes in light has developed into a trend. As a paint for building exterior wall decoration, pigments of different colors are usually added to change the color of the paint. It shows different decorative effects under the sunlight during the day. But when the natural light disappears, the decorative effect of traditional paint also disappears, and colors or other artistic shapes cannot be displayed. This means that traditional decorative ...

Problems solved by technology

[0005] However, the main components of traditional luminescent paints for exterior wall decoration are mostly organic substances such as resins, emulsions, and alcohols and lipids. They are prone to aging and deterioration under the long-term action of ultraviolet rays such as sun exposure, so it is easy to affect the luminous effect of the paint and reduce the paint. Decorative function, and the service life is short, the durability is poor
