Embodiment

[0034] The polyamide 6 / fluorescein composite material provided in this example is prepared by in-situ polymerization. During the preparation process, fluorescein is used as a filler and adipic acid is used as a catalyst. The specific preparation process is as follows:

[0035] (1) Add 100 g of ε-caprolactam, 2 mL of distilled water, 1.0 g of adipic acid, and fluorescein (0.1 g, 0.3 g, 0.5 g, 0.7 g, and 0.9 g of fluorescein) into a three-necked flask, and heat Melt magnetic stirring, raise the system from room temperature to 190°C, and reflux for 3 hours;

[0036] (2) After the reaction in step (1) is completed and the water vapor is released, the temperature of the system is raised to 230°C within 0.5 hours, and then the temperature of the system is gradually raised to 260°C within 1.5 hours;

[0037] Keep this temperature, vacuumize gradually to -0.08MPa, vent, and cast into dumbbell-shaped samples while hot to test the tensile strength of the material, and cast into "V"-shap...

Abstract

The invention belongs to the technical field of polymer compound materials in material science, and particularly relates to a polyamide 6/fluorescein compound material and a production method thereof.The material is produced by adopting an in-situ polymerization method, in a production process, fluorescein is used as filler, and adipic acid is used as a catalyst. During production, firstly, a system is heated to 190-210 DEG C, and reflux reaction is carried out after heating and melting are conducted; after the reaction is completed, vapour is released, then system temperature is elevated to210-230 DEG C, and then the system is gradually heated to 260 DEG C; and finally, vacuumizing is conducted to make pressure reduced gradually to -0.08 MPa. According to the polymer compound material,by adding and using the fluorescein, on one hand, the polymer material performance is greatly improved, and on the other hand, the application range of the polyamide polymeric material is broadened byadding the fluorescent material, so that the polyamide 6/fluorescein compound material has good practical values and application and popularization significance.

Description

technical field [0001] This application belongs to the technical field of polymer composite materials in material science, and specifically relates to a patent application for a polyamide 6 / fluorescein composite material and its preparation method. Background technique [0002] Polymer composite materials are one of the research hotspots in the field of material science. Since this type of material has the characteristics of organic and inorganic materials, and through the interaction between the two, more new and excellent properties can be produced. Performance, multifunctional composite materials are an important way. [0003] In the prior art, there are many methods for preparing polymer composite materials, among which there are four commonly used methods: melt blending method, sol-gel method, intercalation polymerization method and in-situ polymerization method. However, due to the different applicable materials and performance requirements for polymer composites, dif...
