Embodiment 1

[0035] Embodiment 1: A method for preparing a rural experience-type light-storing luminescent material, the preparation method includes the following specific steps:

[0036] Step 1: Mix 16 parts of polyether diol 2000 and 6 parts of polyether triol 3000 into the reactor, and dehydrate for 4 hours at 105°C and 0.1MPa vacuum;

[0037] Step 2: Add 30 parts of acetone solution and 0.01 part of dibutyltin dilaurate solution to the alcohol solution after dehydration, mix, heat to 75°C, add 6 parts of triphenylmethane triisocyanate, and keep warm at 75°C for 2 hours;

[0038] Step 3: After the NCO value in the above solution reaches the theoretical value, add 4 parts of red long-lasting luminescent material CaS:Eu, Dy, and continue the heat preservation reaction for 1.5 hours to obtain a single-component light-storing polyurethane luminescent material.

Embodiment 2

[0039] Embodiment 2: A method for preparing a rural experience-type light-storing luminescent material, the preparation method includes the following specific steps:

[0040] Step 1: Mix 12 parts of polyether diol 2000 and 4 parts of polyether triol 3000 into the reactor, and dehydrate for 3.5 hours at 103°C and 0.05MPa vacuum;

[0041] Step 2: Add 20 parts of acetone solution and 0.01 part of dibutyltin dilaurate solution to the dehydrated alcohol solution, mix, heat to 70°C, add 4 parts of triphenylmethane triisocyanate, and keep the reaction at 70°C for 1.5h ;

[0042] Step 3: Add 2 parts of red long-lasting luminescent material CaS:Eu,Dy to the above catalytic reaction, and continue the heat preservation reaction for 0.8h to obtain a single-component light-storing polyurethane luminescent material.

Embodiment 3

[0043] Embodiment 3: A method for preparing a rural experience-type light-storing luminescent material, the preparation method includes the following specific steps:

[0044] Step 1: Mix 20 parts of polyether diol 2000 and 8 parts of polyether triol 3000 into the reactor, and dehydrate for 4.5 hours at 108°C and 0.2MPa vacuum;

[0045] Step 2: Add 35 parts of acetone solution and 0.1 part of dibutyltin dilaurate solution to the dehydrated alcohol solution, mix, heat to 78°C, add 8 parts of triphenylmethane triisocyanate, and keep the reaction at 78°C for 2 hours;

Abstract

The invention provides a preparation method of a rural experience type light-storing luminescent material. The preparation method comprises the following specific steps: dehydrating a mixed solution of dihydric alcohol and trihydric alcohol at 100-110 DEG C under the vacuum condition of 0.05-0.2 MPa for 3-5 hours; adding an aliphatic ketone solution and an organic tin solution into the dehydratedalcohol solution, mixing, heating to 70-80 DEG C, adding triphenylmethane triisocyanate, and carrying out heat preservation reaction for 1.5-2.5 hours at 70-80 DEG C; and adding the light-storing luminescent material into the catalytic reaction, and continuing the heat preservation reaction to obtain the single-component light-storing polyurethane luminescent material. According to the luminescentmaterial prepared by the method, the light-storing and light-emitting functions of the coating are improved, the problems of the traditional fluorescent coating are solved, and the obtained luminescent material has the advantages of increased light-emitting stable strength, difficulty in migration, lasting and stable maintenance of a light-emitting group, excellent glossiness and weather resistance, difficulty in quenching and typical light-storing and light-emitting enhancement effect.

Description

technical field [0001] The invention relates to the field of luminescent paints, in particular to a method for preparing a rural experience-type light-storing luminescent material. Background technique [0002] In recent years, the country has vigorously implemented the strategy of rural revitalization, and rural tourism has continued to prevail, and there is still a lot of room for development of the rural night economy. In the night economy of the tourism industry, it is often necessary to use a large number of lights to create experience scenes, and the use of a large number of lights makes the rural environment urbanized and loses its rural characteristics, and the use of a large number of lights will cause light pollution to the rural environment, which is not in line with the national concept of ecological environment construction. [0003] Light-storing self-luminous material is a new type of environmentally friendly material that can absorb light energy by itself dur...
