Abstract

The invention discloses a high weather resistance polysiloxane type luminous paint and a preparation method thereof. A high-weather-resistant polysiloxane type luminous paint, in parts by mass, comprising the following components: 100 parts of methyl vinyl silicone oil, 10-20 parts of methyl hydrogen-containing silicone oil, and 30-60 parts of methyl MQ resin , 5-10 parts of vinyl MQ resin, 5-15 parts of luminous powder, 0.01-0.06 part of inhibitor and 0.1-0.2 part of curing agent. The polysiloxane matrix selected for the luminous paint prepared by the invention has a moderate viscosity, which can effectively prevent the luminous powder from settling after the viscosity is too low, so as to achieve uniform distribution of the luminous powder in the coating layer, so that the luminous intensity of the luminous paint film after molding has consistency.

Description

technical field [0001] The invention relates to the technical field of luminous paint, in particular to a polysiloxane-type luminous paint with high weather resistance and a preparation method thereof. Background technique [0002] Luminous powder is aluminate activated by a variety of rare earth ions. After being excited by light, it can continue to glow in the dark for a long time. Adding luminous powder to polymers makes luminous paint, which has bright colors, long luminous time, and high brightness. High, widely used in architectural decoration, artificial landscape, outdoor signs and other fields. At present, luminous paints are generally divided into two types: oil-based paints and water-based paints. The former is prepared by dispersing luminous powder and polymer matrix in an organic solvent. During construction, the solvent evaporates to form a paint film. This process pollutes the environment, so It is restricted in many occasions and gradually replaced by water-...
