Problems solved by technology

The resins currently used mainly include polyurethane, acrylic resin and polyester resin. Polyurethane fluorescent coatings contain solvents, which are harmful to the environment. Polyester resin has poor chemical resistance, while acrylic resin has limited thermoplastic properties, which makes it easy to stick back at high temperature. Sticky to dust, brittle at low temperature, limited use; organic fluorescent pigments have poor weather resistance, chemical resistance and heat resistance, and the luminous time is not long

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;

Abstract

The invention discloses a luminous epoxy paint and a preparation method thereof. The paint is obtained by compounding a component A and a component B, wherein the component A comprises the following components by weight percent: 40-55% of epoxy resin, 40-55% of fluorescent powder, 2-8% of thickening agent, 0.1-0.6% of defoaming agent and 0.1-0.6% of levelling agent; the component B comprises the following components by weight percent: 40-55% of curing agent, 40-55% of fluorescent powder, 2-8% of thickening agent, 0.1-0.6% of defoaming agent and 0.1-0.6% of levelling agent; and the component A and the component B are compounded according to the part ratio of 1:1) to 2:1) The paint has the following beneficial effects: the paint has longer luminescence time, the fluorescent effect is enhanced and the fluorescent powder is not easy to pulverize; and in the use process, the fluorescent paint has good yellowing and weather resistances and long service life.

Description

Technical field: [0001] The invention relates to the field of luminous coatings, in particular to an epoxy luminous coating and a preparation method thereof. Background technique: [0002] Fluorescent paint is a paint with a very strong color sense and can emit bright and dazzling colors under sunlight. It is mainly used in architectural paint, decoration design, railways, highways, artificial landscapes, billboards, etc., but the general fluorescent paint has poor adhesion. , It is easy to pulverize under sunlight exposure. The main film-forming substances of commercially available fluorescent paints are acrylic or modified acrylic resins, polyester resins, and polyurethane resins, while fluorescent pigments mainly use organic fluorescent dyes. The resins currently used mainly include polyurethane, acrylic resin and polyester resin. Polyurethane fluorescent coatings contain solvents, which are harmful to the environment. Polyester resin has poor chemical resistance, while ...
