Abstract

The invention discloses a stiffness and toughness balanced ternary blend alloy material which is prepared from the following components in parts by weight: 30-90 parts of POK polyketone, 5-30 parts ofnylon elastomers, 5-70 parts of PA6, 0.05-0.3 part of a nucleating agent, 0.05-1 part of a lubricating agent, 0.05-0.3 part of a primary antioxidant and 0.05-0.3 part of an auxiliary antioxidant. Theinvention further provides a preparation method of the ternary blend alloy material. The preparation method comprises the following steps: mixing the components in parts by weight, and performing melt extrusion granulating by a twin-screw extruder unit, thereby obtaining the ternary blend alloy material disclosed by the invention. Compared with ordinary POK or nylon, the ternary blend alloy material disclosed by the invention maintains low water-absorbing quality and high wear resistance of the POK material, the characteristics of the nylon material such as high modulus and excellent chemicalresistance are additionally increased, and another function that is not owned by the two is increased, namely, the excellent characteristic of high toughness.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to polymer plastic alloy composite materials, in particular to a ternary blend alloy material with balanced rigidity and toughness and a preparation method thereof. Background technique [0002] POK polyketone (polyketone) is a kind of crystalline engineering plastic with excellent comprehensive performance developed and produced by Korea Hyosung Group. material. [0003] The material has high heat distortion temperature, chemical resistance, hydrolysis resistance, fuel resistance, high friction resistance, low gas permeability, high barrier property, etc., and its wear resistance is more than 14 times that of POM. [0004] Polyketone POK was successfully developed by Hyosung for the first time. It mainly uses a new polymer material composed of carbon monoxide, which is a serious air pollutant, and petrochemical raw materials (ethylene, propylene). The advantages of polyketone are wear re...
