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,...

Abstract

The invention discloses a high-performance filling enhanced modified PTT polyester composite material. The composite material comprises the following ingredients, by weight, 70%-90% of PTT, 5%-20% of composite filling materials, 2%-5% of polyethylene glycol, 0.5%-2% of light stabilizing agents, 0.1%-1% of potassium Perfluorobutanesulfonate, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The composite filling materials are composite filling materials composed of 50wt% of heavy calcium carbonate, 25wt% of precipitated barium sulphate, 20wt% of nano montmorillonite and 5wt% of aluminum titanium composite coupling agents. The beneficial effects are that the composite material has excellent heatproof stability and flame retardation performances, the enhanced modified effects are good through preparation of the composite filling materials, the intensity is high, the chemical resistance is strong, the dimension stability is good, surfaces of products are bright and clean, the ageing resistance is good, the cost is low, and popularization is easy.

Description
