Embodiment 1

[0016] A nano-bamboo carbon PTT reinforced masterbatch, its components are proportioned by mass percentage: PTT resin 28%, glass fiber 20%, nano-bamboo carbon 25%, ACR 15%, E-MA-GMA 6%, Shuangma 3.5% imide, 2.5% TAF, the glass fiber is an alkali-free chopped glass fiber whose surface is modified by a silane coupling agent and has an average diameter of 8-15 μm, and the nano-bamboo carbon is a surface treated with a nanometer Nano-bamboo carbon modified by titanium dioxide with a particle size of 20-80nm.

[0017] Preparation method: Weigh each component according to the weight ratio, and add PTT resin, nano bamboo carbon, ACR, E-MA-GMA, bismaleimide and TAF into a high-speed mixer and mix for 3 to 15 minutes. After fully mixing evenly, the material is discharged into the main feeding port of the twin-screw extruder, and at the same time, the glass fiber weighed according to the weight ratio is added from the side feeding port of the twin-screw extruder, and melted and mixed by...

Abstract

The invention discloses a nano bamboo carbon PTT enhanced master batch. The nano bamboo carbon PTT enhanced master batch comprises the following ingredients, by weight, 15%-50% of PTT resins, 10%-30% of glass fibers, 15%-40% of nano bamboo carbon, 10%-25% of ACR, 3%-8% of compatibilizers, 2%-5% of heat resistant agents and 0.5%-3% of dispersants. The beneficial effects are that the enhanced master batch has functions of no pollution, high dispersion, high intensity, and strong adsorption, sterilization, deodorizing, purifying and anti ultraviolet functions, when 5%-15% of the enhanced master batch is added in PTT production, good sterilization, toughening, reinforcing and anti-ultraviolet modification effects are achieved, the heat resistance, processing properties and appearance quality of the material are raised obviously, the production cost is lowered, and the production efficiency is raised.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a nano bamboo carbon PTT reinforced masterbatch. Background technique [0002] Polytrimethylene terephthalate (PTT) is a kind of poly(ethylene terephthalate) (PET) and polybutylene terephthalate obtained by polycondensation of terephthalic acid and 1,3-propanediol. Alcohol ester (PBT) is a new type of polyester polymer material, and PTT is more excellent than PET and PBT in terms of mechanical properties, weather resistance, heat aging resistance and hydrolysis resistance. Due to its excellent comprehensive properties, PTT is widely used in the fields of fibers, films, engineering plastics, etc. However, when PTT is used alone, it has the defects of low notched impact strength and high notch sensitivity, which will greatly limit the application of PTT in various fields. Contents of the invention [0003] The object of the present invention is to provide a kind of na...
