Embodiment 1
[0033] This example provides four preparation methods for LCP / HBN composite materials.
[0034] According to the formula of Sample 1 and Comparative Samples 1 to 3 shown in Table 1, the ingredients were mixed and mixed in a high-speed mixer of 35000 r / min for 5 minutes, and then melt-blended using a polymer material plasticization and transportation equipment based on extensional rheology. , the temperature of each section is 230-300-310-310 ° C, the rotor speed is 45 rpm, extrusion molding, cooling, drying, that is, four kinds of LCP / HBN composite materials are obtained.
[0035] The above materials were dried in a vacuum drying oven at 130° C. for 6 hours, and the dried LCP / HBN composite sheets were arranged in a fixed direction, which was consistent with the melt flow direction during extrusion. The samples were prepared by hot pressing with a flat vulcanizer, the temperature was 300 °C, the preheating time was 15 min, the hot pressing was 3 min, and the cold pressing was 5...
Embodiment 2
[0039] This embodiment provides 6 kinds of LCP / HBN composite materials and preparation methods thereof.
[0040] According to the formulas of samples 1 to 3 and comparative samples 1, 4 and 5 shown in Table 2, the ingredients were mixed, mixed in a 35000r / min high-speed mixer for 5 minutes, and then plasticized and transported using an extensional rheology-based polymer material. The equipment is melt-blended, the temperature of each section is 230-300-310-310°C, the rotor speed is 45 rpm, extrusion molding, cooling and drying, that is, 6 kinds of LCP / HBN composite materials are obtained.
[0041] The above materials were dried in a vacuum drying oven at 130° C. for 6 hours, and the dried LCP / HBN composite sheets were arranged in a fixed direction, which was consistent with the melt flow direction during extrusion. The samples were prepared by hot pressing with a flat vulcanizer, the temperature was 300 °C, the preheating time was 15 min, the hot pressing was 3 min, and the co...
