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;
[0046] Step 3: Add 6 parts of red long-lasting luminescent material CaS:Eu,Dy to the above catalytic reaction, and continue the heat preservation reaction for 1.8 hours to obtain a single-component light-storing polyurethane luminescent material.
