Embodiment 1
[0018] A high-performance composite material filled with reinforced modified PTT polyester. Its components are proportioned by mass percentage: PTT 73%, composite filler 20%, polyethylene glycol 5%, light stabilizer 1.5%, perfluorobutyl Potassium sulfonate 0.1%, antioxidant 1076 0.1%, pentaerythritol stearate 0.3%, the PTT is polytrimethylene terephthalate with an intrinsic viscosity of 0.7 to 1.2 dL / g, and the composite filler is made of heavy A composite filler made of 50wt% calcium carbonate, 25wt% precipitated barium sulfate, 20wt% nano-montmorillonite and 5wt% aluminum-titanium composite coupling agent. The light stabilizer is a hindered amine light with a mass ratio of 1:1. A compound of stabilizer HS-944 and HS-622.
[0019] Preparation method: (1) Put the PTT in a forced air circulation oven and dry it at a temperature of 110℃~120℃ for about 6-8 hours, and then wait for use; (2) Prepare the composite filler: weigh it according to the weight ratio 50wt% calcium carbonate,...
