Fluorescent material can be obtained by dispersing organic fluorescent pigment in acrylic resin.
This kind of fluorescent material has relatively high light retention and weather resistance. However, this kind of fluorescent material has a great disadvantage, such as its thermoplasticity will lead to return adhesion at high temperature and brittle crack at low temperature.
These problems greatly limit the use of fluorescent materials.
Some researchers will modify acrylic emulsion through organosilicone, and use the modified material as a film-forming material, and then disperse ordinary solid pigments in the modified material to make high-quality coatings.
For the newly made coatings, because of its strong application advantages, is favored by people.
For example, the construction is convenient, low cost, with a certain dustproof.
In addition, some researchers obtained high-performance fluorescent coatings by analyzing fluorescent pigment emulsion in silicone modified acrylic resin base material.
According to the specific research results, it is necessary to control the pH of the resin at 6~7 and the reaction temperature at 62~64℃ in the process of preparing resin.
Then the fluorescent pigment emulsion is added to the substrate emulsion to make a new fluorescent coating.
