Description
Technical Field
The invention relates to the field of fluorescent materials, in particular to a composite fluorescent material, a preparation method thereof and a prepared fluorescent PVC material.
Background
Fluorescent polyvinyl chloride (PVC) materials generally fall into two broad categories: intrinsic fluorescent PVC material and additive fluorescent PVC material. The intrinsic fluorescent PVC material is prepared by adding a molecular P electron conjugated system, such as compounds containing pi bonds such as aromatic rings, into a PVC matrix and carrying out block polymerization to form a corresponding PVC polymer. The additive fluorescent PVC material is prepared by adding inorganic fluorescent powder into a PVC matrix, wherein the inorganic fluorescent powder is sulfide or sulfate of heavy metal.
Chinese patent application CN108178809A discloses a master batch of indole functionalized polyvinyl chloride, which prepares a modified polyvinyl chloride material with good fluorescence function by carrying out Friedel-Crafts alkylation reaction on indole micromolecules with aromaticity. However, the intrinsic fluorescent PVC material has a light-emitting principle that P electrons in a conjugated system are recovered from s2 state to s1 state, so that the fluorescent efficiency is low, and double bonds are easily isomerized during the copolymerization with a polymer, and the fluorescent property is lost.
Chinese patent application CN 109795143 a discloses a color fluorescent light-storing and light-emitting PVC plate, which is made by mixing PVC material with luminescent powder (i.e. inorganic fluorescent powder) and extrusion molding, so that the PVC plate can store light and emit light. However, the inorganic fluorescent powder has poor compatibility with PVC, is not easy to disperse, is unstable in a damp and hot environment, is easy to decompose into acid sulfate, and damages the PVC matrix.
Fluorescent plastic markers used in coastal areas or mine roadway pipes generally require high fluorescence efficiency and have strong resistance to damp-heat environments. Therefore, there is a need to develop a composite fluorescent material with high fluorescence efficiency and stability, and a fluorescent PVC material resistant to a damp-heat environment.
Disclosure of Invention
In order to overcome the defects of poor fluorescence efficiency and poor humidity and heat environment resistance in the prior art, the invention provides a composite fluorescent material which has high and stable fluorescence efficiency.
The invention also aims to provide a preparation method of the composite fluorescent material.
The invention also aims to provide a fluorescent PVC material resistant to damp and hot environments, which comprises PVC and the composite fluorescent material.
The invention also aims to provide a preparation method of the fluorescent PVC material.
In order to solve the technical problems, the invention adopts the technical scheme that:
the composite fluorescent material comprises the following components in parts by weight:
2-10 parts of cerium nitrate,
10-18 parts of lanthanum nitrate,
5-20 parts of acetic acid,
20-60 parts of pyromellitic dianhydride,
20-60 parts of ethylene diamine,
0.05-0.6 part of manganese sulfate catalyst.
The polymer-inorganic composite fluorescent material with the block characteristic is prepared by combining the light-emitting mechanism of the organic fluorescent material and the inorganic fluorescent material. Acetic acid, pyromellitic dianhydride and ethylenediamine are heated under the action of a manganese sulfate catalyst to generate Polyimide (PI), and the PI can effectively improve the stability of PVC, so that chloride ions in PVC are not easy to overflow, and lanthanum ion or cerium ion poisoning is avoided. Although a variety of organic polyacids and polyamines can undergo amidation reactions to form polymers, there are great differences in the properties of the various polymers. The polymer generated by the reaction of pyromellitic anhydride and ethylenediamine has high mechanical property and good compatibility with PVC.
Cerium nitrate and lanthanum nitrate have high-efficient fluorescence efficiency as rare earth metal salt, and lanthanum ions and cerium ions simultaneously react and combine with acid groups in pyromellitic dianhydride in the reaction process, so that the fluorescent substance is more stable and difficult to decompose in a damp and hot environment, the high-efficient fluorescence efficiency is maintained, and the PVC substrate is not damaged.
If only lanthanum nitrate is used as the rare earth metal salt, or the weight of lanthanum nitrate is less than that of cerium nitrate, the composite fluorescent material with good fluorescence efficiency cannot be obtained. The inventor researches and discovers that although lanthanum nitrate and cerium nitrate have certain fluorescence performance, a higher luminous effect can be achieved only when the lanthanum nitrate and the cerium nitrate are compounded and used, and lanthanum nitrate is used as a matrix, and the cerium nitrate is uniformly dispersed in the lanthanum nitrate matrix. If the weight of the cerium nitrate is too much, the cerium nitrate is easy to agglomerate and reduce the light sensitivity, and light particles are easy to absorb or scatter, thereby influencing the luminous efficiency and the fluorescence efficiency.
Preferably, the weight ratio of the cerium nitrate to the lanthanum nitrate is (1-3) to (9-7).
Preferably, the weight ratio of the pyromellitic dianhydride to the ethylenediamine is (2-3) to (3-2)
The inventor researches and discovers that when the weight ratio of cerium nitrate to lanthanum nitrate is (1-3) to (9-7) and the weight ratio of pyromellitic anhydride to ethylenediamine is (2-3) to (3-2), the fluorescence efficiency of the composite fluorescent material is better.
Preferably, the weight ratio of the cerium nitrate to the lanthanum nitrate to the weight ratio of the pyromellitic dianhydride to the ethylene diamine is (1-5) to 10.
The invention also provides a preparation method of the composite fluorescent material, which comprises the following steps:
s1, dissolving cerium nitrate and lanthanum nitrate in an acetic acid solution to obtain a first mixed solution; dissolving pyromellitic dianhydride, ethylenediamine and a manganese sulfate catalyst in a monohydric alcohol solution to obtain a second mixed solution;
s2, uniformly mixing the first mixed solution and the second mixed solution, heating for reaction, and cooling to obtain the composite fluorescent material.
Preferably, the monohydric alcohol solution is a methanol solution, an ethanol solution or a propanol solution.
Preferably, the heating reaction in step S2 is carried out at 100-120 ℃ for 30-90 min.
The invention also discloses a fluorescent PVC material capable of resisting the damp and hot environment, which comprises PVC and the composite fluorescent material.
The polymer-inorganic composite fluorescent material with the block characteristic, which is constructed by the invention, contains a fluorescent polymer chain segment and has good compatibility with a PVC matrix; the rare earth luminescent element synthesized in situ is used as a luminescent center, so that the fluorescent efficiency is high; the rare earth luminescent element is combined with the acidic group reaction of the organic matter, so that the material has better adaptability to the damp and hot environment, is not easy to decompose, and has high fluorescence efficiency. The prepared fluorescent PVC material has excellent fluorescence efficiency, is resistant to damp and hot environments, and still keeps good fluorescence performance in the damp and hot environments.
Preferably, the PVC is powdered PVC.
Preferably, the weight ratio of the PVC in the fluorescent PVC material to the composite fluorescent material is (1-5) to (99-95).
The invention also provides a preparation method of the fluorescent PVC material, which comprises the following steps:
and blending the composite fluorescent sample with PVC, and performing extrusion forming to obtain the fluorescent PVC material with the damp-heat resistant environment.
Preferably, the composite fluorescent sample is crushed and then blended with PVC.
The comminution may be carried out using conventional comminution equipment. Optionally, the crushing plant is a jaw crusher or a roll crusher.
The extrusion molding can use extrusion molding equipment commonly used for PVC materials. Optionally, the extrusion molding uses a twin screw extruder.
Preferably, the average particle size of the powder composite fluorescent sample is 30-50 μm.
Compared with the prior art, the invention has the beneficial effects that:
the polymer-inorganic composite fluorescent material with the block characteristic is constructed by combining the light-emitting mechanism of the organic fluorescent material and the inorganic fluorescent material, and the polymer-inorganic composite fluorescent material has good compatibility with a PVC matrix due to the existence of the fluorescent polymer chain segment; the rare earth luminescent element synthesized in situ is used as a luminescent center, so that the fluorescent efficiency is high; the rare earth luminescent element is combined with the acidic group reaction of the organic matter, so that the material has better adaptability to the damp and hot environment, is not easy to decompose, and has high fluorescence efficiency.

The test results of examples 1 to 8 and comparative examples 1 to 5 are shown in Table 1.
TABLE 1 test results of examples 1 to 8 and comparative examples 1 to 5
| Initial fluorescence efficiency | Fluorescence efficiency after salt spray test treatment | |
| Example 1 | 69％ | 68％ |
| Example 2 | 65％ | 63％ |
| Example 3 | 63％ | 62％ |
