Embodiment 1

[0016] An antistatic polytrimethylene terephthalate resin, its components are proportioned by mass percentage: PTT 76%, glass fiber 12%, glycidyl methacrylate grafted ethylene-octene copolymer 8%, fatty acid Polyethylene glycol ester 2%, 2-hydroxy-4 n-octyloxy-benzophenone 1.5%, antioxidant 1010 0.2%, modified ethylene bis fatty acid amide 0.3%, the PTT is an intrinsic viscosity of 0.7~ 1.5 dL / g of polytrimethylene terephthalate, the glass fiber is an alkali-free glass fiber whose surface is modified by a silane coupling agent, with a diameter of 8-12 μm and a length of 3-6 mm.

[0017] Preparation method: Weigh each component according to the weight ratio, and mix PTT, glycidyl methacrylate grafted with ethylene-octene copolymer, fatty acid polyethylene glycol ester, 2-hydroxy-4 n-octyloxy-di Add benzophenone, antioxidant 1010, and modified ethylene bis fatty acid amide into a high-speed mixer and mix for 3 to 15 minutes. Add the glass fiber weighed according to the weight r...

Embodiment 2

[0019] An antistatic poly(trimethylene terephthalate) resin, whose components are proportioned by mass percentage: 85% PTT, 8% glass fiber, 5% glycidyl methacrylate grafted ethylene-octene copolymer, poly 1% of ethylene glycol alkyl ether, 0.5% of 2,4-dihydroxybenzophenone, 0.1% of the compound of antioxidant 1076 and antioxidant 168, and 0.4% of modified ethylene bis-fatty acid amide. PTT is poly(trimethylene terephthalate) with an intrinsic viscosity of 0.7-1.5dL / g, and the glass fiber is a glass fiber whose surface is modified by a silane coupling agent, with a diameter of 8-12μm and a length of 3-6mm.

Abstract

The invention discloses an antistatic PTT resin, which comprises the following components by mass: 75%-85% of PTT, 8%-12% of glass fiber, 4%-8% of a toughening modification agent, 1%-3% of an antistatic agent, 0.5%-2% of a light stabilizer, 0.1%-0.5% of an antioxidant, and 0.1%-1% of a lubricant. The toughening modification agent is a glycidyl methacrylate grafted ethylene-octene copolymer, and the antistatic agent is one of fatty acid polyethylene glycol ester, polyethylene glycol alkyl ether, and glycerol monostearate. The antistatic PTT resin provided by the invention has excellent antistatic performance and good impact resistance, and also has high strength, strong aging resistance, smooth and clean product surface, and good appearance, thus being easy to popularize.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antistatic polytrimethylene terephthalate resin. Background technique [0002] Polytrimethylene terephthalate (PTT), as a new type of polyester polymer material with excellent comprehensive properties, has been widely used in the fields of fibers, films, engineering plastics, etc., but unmodified PTT has low notched impact strength, The defects of large notch sensitivity and insufficient antistatic property greatly limit the wider application of PTT in various fields. Contents of the invention [0003] The object of the present invention is to provide a kind of antistatic polytrimethylene terephthalate resin. [0004] The technical solution adopted by the present invention to solve the technical problem is: an antistatic poly(trimethylene terephthalate) resin whose components are proportioned by mass percentage: PTT 75%-85%, glass fiber 8%-12% , toughening modifi...
