Preparation method of polyvinylidene fluoride (PVDF)/ethylene-butyl acrylate-glycidyl methacrylate copolymer (PTW) alloy

The invention discloses a preparation method of a polyvinylidene fluoride (PVDF)/ethylene-butyl acrylate-glycidyl methacrylate copolymer (PTW) alloy. The copolymer alloy comprises the following raw materials in parts by weight: 50-70 parts of PTW, 30-50 parts of PVDF, 1-7 parts of poly(butylene succinate), 0.1-5 parts of free radical stabilizer, 0.05-1 part of antioxidants, 0.1-3 parts of anti-aging agents and 1-20 parts of plasticizers. A compatibilization modification method can achieve the effects of not only effectively improving the properties of the PVDF/PTW alloy material but also enabling the PVDF/PTW alloy material to be mixed more uniformly, the phase shape to be more stable and the PVDF/PTW alloy material to be more favorable to form and can also achieve the effects of well solving the problem that the PVDF/PTW alloy material undergoes extrudate swelling and melt cracking in the extrusion processing process and improving the tensile strength, elongation at break, and the like of the PVDF/PTW alloy material. At the same time, the method has great significance in expanding the application of the PVDF material.
