Example Embodiment
[0020] Example 1
[0021] Such as figure 1 As shown, this embodiment 1 provides a polyvinylidene fluoride-polyethylene composite material, which consists of polyvinylidene fluoride: 10-50 parts by weight; polyethylene: 10-50 parts; compatibilizer: 1 -10 parts; compatibilizer: 1-10 parts; flame retardant: 5-35 parts; lubricant: 0.1-1 part; and antioxidant: 0.5-3 parts. Preferably, the polyvinylidene fluoride is 15-25 parts.
[0022] Melt flow rate (MFR) is the standard capillary tube where the resin melt passes through a standard capillary at a certain temperature and pressure, and the unit is g / 10min. The melt flow rate is an important reference for the selection of plastic processing materials and grades, which can make the selected raw materials better meet the requirements of the processing technology, and improve the reliability and quality of the products. Therefore, in plastic processing, by measuring the flow rate of the plastic, the structural factors of the polymer can b...
