From the detection results of the above examples, it can be seen that with the increase of the relative proportion of bisphenol a diglycidyl ether and sebacic acid, the ultimate tensile strength of the prepared glass-like polymer material is continuously increased, but the breaking strain thereof shows a significantly decreasing trend. When the TBD content is 0.05 percent, the reaction efficiency is relatively high and sufficient. However, when the ultimate tensile strength reaches 12.69MPa, namely the proportion of the experimental group 6, the fracture strain value is close to the typical value of the existing material, and when the fracture strain value is lower than the typical value, the application range of the material is narrow, so that the material cannot be applied to many fields. Meanwhile, although the experimental groups 10-14 have better ultimate tensile strength, the ultimate tensile strength is not obvious and is slightly increased compared with the experimental group 6, but the catalyst content is higher and the production cost is greatly increased, so that the catalyst proportion reaches 0.05, and the catalyst proportion is an optimal catalyst proportion of the application. Since the ultimate tensile strength value of the material is a more important influencing factor than the fracture strain value of the glass-like polymer material in the present application, it can be known from the above-mentioned detection results that the ratio of bisphenol a diglycidyl ether in experimental group 6: sebacic acid: TBD =1:0.75:0.05 is the optimal proportion of the composition. The ultimate tensile strength reaches 12.69MPa, the breaking strain reaches 107 percent, the standard value of the breaking strain is met, and the ultimate tensile strength is obviously improved. Compared with the prior art and other proportioning embodiments, the material has obvious substantive characteristics and remarkable progress.
Analysis may be caused by the fact that different molecular chains of glass-like high molecular materials are generated due to different reactant ratios of bisphenol a diglycidyl ether and sebacic acid in the reaction process and different catalyst contents, so that in different bisphenol a diglycidyl ethers: under the matching of sebacic acid, glass-like high polymer materials with great difference in performance are generated. When the proportion is 1: at 0.75, the ultimate tensile strength and the breaking strain both reach the optimum requirements, and if the breaking strain value is too low, the ultimate tensile strength is insufficient. Meanwhile, when the TBD is in a proportion of less than 0.05, the product performance is obviously lower, and the product cannot be used at all, when the TBD exceeds 0.05, the product performance is stable, and when the TBD exceeds 0.05, the material performance is slightly improved, but the difference is not large, and the bisphenol A diglycidyl ether and the sebacic acid can be fully reacted possibly by the proportion of 0.05. In addition, the raw materials with different proportions can cause the glass-like polymer material to contain certain impurities after reaction, and simultaneously, the overall performance of the product has larger difference due to different impurity components. The test results of the application show that bisphenol a diglycidyl ether: sebacic acid: TBD =1:0.75: when the weight is 0.5, the product performance is optimal, and the method is also an optimal embodiment of the application. The glass polymer material produced according to the proportion has the advantages of optimal performance and lowest production cost.
Through the combination of bisphenol A diglycidyl ether, sebacic acid and TBD, the preparation method is simpler in process, higher in preparation efficiency, capable of realizing batch production, and capable of effectively eliminating the release of toxic substances in the preparation process of the glass-like high polymer material, so that the prepared glass-like high polymer material has higher ultimate tensile strength and better fracture strain parameter values.
While the invention has been described in terms of its preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
