In the following examples, glycerol-modified PVA was obtained by adding 10 to 50% by mass of glycerol to PVA and sufficiently impregnating the PVA.
Example 1
The firmware material of this embodiment has the following composition in mass percent:
TABLE 1 formulation of PVA-based firmware Material
The firmware material prepared in this example was used in a Vicat thermal deformation tester (Meter industries, inc., china), DSC8500 (Perkin Elmer, USA), TA Q5000IR thermo-analyzer (TA Instruments Inc., U.S.) to test its Vicat softening temperature, DSC, TG and DTG, as follows:
vicat softening temperature test method: placing the sample into a high-temperature silicone oil heat transfer medium, heating at a heating rate of 50 ℃/h, placing a weight of 50N, and testing the sample by 1mm 2 The temperature at which the needle is pressed into the cavity of the needle is 1mm, namely the Vicat softening point. The sample size was 10mm×10mm×3mm, and the number of stacked layers was 1.
DSC test method: the samples were ground to a powder and tested under nitrogen atmosphere at a heating rate of 20 c/min.
TG and DTG test method: the samples were ground to powder and tested in an air atmosphere at a heating rate of 20 ℃/min to 800 ℃.
Vicat softening temperature test results: the vicat softening temperatures of the firmware materials based on PVA are shown in table 2. As can be seen from table 2, the vicat softening temperature of PVA is lower as the amount of glycerol added is greater, so that screening out an effective glycerol addition ratio is a key step in balancing the processability and heat resistance of PVA heat resistant composite materials. Through the Vicat softening point test, when the glycerol addition amount is 10%, the Vicat softening temperature of the composite material prepared from jute fibers and bamboo powder with different addition amounts is almost above 100 ℃. A composite of 20% glycerol swollen PVA with a vicat softening temperature up to 60% jute fiber.
TABLE 2 Vicat softening temperature of firmware Material with PVA as the main matrix
DSC test results: the DSC curves of samples No. 11-15 are shown in FIG. 1, and the DSC curves of samples No. 16-20 are shown in FIG. 2. It can be seen that no significant melting peak and no phase transition occurs for all samples nor does a significant chemical reaction occur. The existence of glycerin obviously damages the crystallization property of PVA, and reduces the processing temperature of PVA, so that the PVA is feasible to be filled with the temperature-resistant filler. As can be seen from fig. 2, the PVA composite material having 20% glycerol content shows a phenomenon of crystallization melting at 105 ℃, which means that there is still a part of PVA not swollen by glycerol and thus there is still crystallized PVA, which has an influence on the melt processability of PVA, thus resulting in insufficient dispersion of filler in the PVA composite material. It can also be seen from the DSC curve that the PVA composite with 20% glycerol content shows some degree of side group elimination and main chain decomposition around 160 ℃. Thus, the PVA composite having a glycerol content of 30% is most practical.
TG and DTG test results: the thermal gravimetric analysis results of samples No. 11-15 are shown in fig. 3, and the thermal gravimetric analysis results of samples No. 16-20 are shown in fig. 4 for the barrier firmware material with PVA as the main substrate. Because the samples No. 11-15 are PVA with 30% of glycerol content, in PVA composite materials with different glycerol contents, the average Vicat softening temperature is higher (94.9 ℃) and the hardness is lower on average, the average heat conductivity coefficient is lowest, the Vicat softening temperature is higher than 80 ℃, and the PVA is the maximum proportion of swellable glycerol. Samples 11-15 were therefore selected for thermogravimetric analysis. As can be seen from fig. 3, the thermal decomposition of PVA with 30% glycerol content is mainly divided into four stages: desiccation (room temperature-100 ℃ C.), glycerol overflow (100-261 ℃ C.), elimination of pendant groups of PVA (261-400 ℃ C.), and decomposition of the main chain of PVA (400-600 ℃ C.). The 30% glycerol PVA without filler has a second stage weight loss of 33%, a peak weight loss rate of 0.44%/min, a third stage weight loss of 37%, a peak weight loss rate of 42%/min, a fourth stage weight loss of 19%, and a peak weight loss rate of 0.28%/min. It can be seen that the peak weight loss rate temperature at each stage decreases with the addition of filler. The weight loss of the second stage of the filled PVA composite is lower than the 30% glycerol content PVA without filler. The peak weight loss rate in the third and fourth stages of the filled PVA composite is higher than that of the filled 30% glycerol content PVA.
Samples 16-20 were all PVA with 20% glycerol content, with an average Vicat softening temperature of 94℃C (No. 16 without filler removed) lower than the average Vicat softening temperature of the composite material with 30% PVA glycerol content (94.9 ℃). As can be seen from fig. 4, the decomposition of the composite material of pva with 20% glycerol content is mainly divided into two parts: the pendant groups of PVA eliminate most of the main chain decomposition (280-400 ℃) and the rest of the main chain decomposition (450-600 ℃). It can be seen that the 20% glycerol addition PVA composite has a lower thermal stability than the 30% glycerol addition PVA composite, and the main chain has been substantially completely decomposed before 400℃and the filler-free 30% glycerol addition PVA composite has 19% of its non-decomposed at 400 ℃.
Through DSC analysis, the PVA modified by the glycerol has relatively lower temperature processing performance, and then the heat resistance of the PVA is obviously improved through the addition of the heat-resistant filler, and the improvement of the Vicat softening point means that the prepared material can play a supporting role after being heated and does not collapse. Analysis of TG and DTG demonstrated good thermal stability of the material, with only glycerol volatilizing off at 20% glycerol swollen PVA below 280 ℃, and only glycerol volatilizing off at 30% glycerol swollen PVA below 261 ℃.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
