Embodiment 1
[0018] Embodiment 1: A kind of epoxy luminescent paint, its composition is by mass percentage: A component includes: bisphenol A type epoxy resin 40%, fluorescent powder 55%, thickener 4%, defoamer 0.4%, Leveling agent 0.6%; B component includes: alicyclic amine curing agent 40%, fluorescent powder 55%, thickener 4%, defoamer 0.6%, leveling agent 0.4%; when using, make A and B groups Composite according to 2:1 evenly, and troweled on the surface of the product to be coated. After using the epoxy luminescent paint of the present invention, the coating film of the product has a longer luminous time of more than 8 hours, the surface of the coating film is smooth, and the adhesion is less than grade 1.
[0019] The preparation method of epoxy luminescent paint in this example is as follows: Preparation of component A: add bisphenol A epoxy resin, fluorescent powder and thickener to reaction vessel A, stir evenly, heat up to 75°C, wait for thickening After the agent is fully disso...
Embodiment 2
[0022] Embodiment two: a kind of epoxy luminous paint, its composition is by mass percentage: A component comprises: bisphenol A type epoxy resin 55%, fluorescent powder 40%, thickener 4%, defoamer 0.4%, Leveling agent 0.6%; component B includes: curing agent 55%, fluorescent powder 40%, thickener 4%, defoamer 0.6%, leveling agent 0.4%; among them, when components A and B are used in combination, The share ratio of the two is A:B=1:1. The luminous time of the coating film of the product is more than 8 hours, the surface of the coating film is smooth, and the adhesion is less than grade 1.
[0023] The preparation method is the same as in Example 1.
Embodiment 3
[0024] Embodiment three: a kind of epoxy luminous coating, its composition is by mass percentage: A component comprises: bisphenol F type epoxy resin 41%, fluorescent powder 50%, thickener 8%, defoamer 0.4%, Leveling agent 0.6%; component B includes: alicyclic amine curing agent 41%, fluorescent powder 50%, thickener 8%, defoamer 0.6%, leveling agent 0.4%; among them, components A and B are combined When used, the ratio of the two is A: B = 2:1. The luminous time of the coating film of the product is more than 8 hours, the surface of the coating film is smooth, and the adhesion is less than grade 1.
[0025] In this example, the epoxy luminous coating is prepared as follows: Preparation of component A: add bisphenol F epoxy resin, fluorescent powder and thickener to reaction vessel A, stir evenly, heat up to 85°C, and wait for thickener After fully dissolving, cool down to normal temperature, add defoamer and leveling agent to the reaction vessel, and stir evenly;
