Abstract

The invention provides a super-tough polyketone (POK) material. The super-tough POK material is prepared from the following components in parts by weight: 70-90 parts of POK, 5-25 parts of an impact modifier, 0.05-0.5 part of a nucleating agent, 0.05-1 part of a lubricant, 0.05-0.2 part of a heat stabilizer, 0.05-0.2 part of a main antioxidant and 0.05-0.2 part of an auxiliary antioxidant. The invention further provides a preparation method of the super-tough POK material. The preparation method comprises the following steps: mixing the raw materials according to the weight parts, and then carrying out melt extrusion granulation by using a double-screw extruder to prepare the super-tough POK material. The super-tough POK material provided by the invention has the characteristics of low specific gravity, high wear resistance, ultrahigh toughness, environmental friendliness and the like, and can be applied to the fields of toy dolls, automobiles, electronics and the like.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to polymer material technology, in particular to a POK polyketone material, in particular to a super-tough POK polyketone material and a preparation method thereof. Background technique [0002] POK is a kind of engineering plastic with extremely excellent comprehensive properties. It belongs to polyketone materials. It is a new type of green polymer material formed by coordination polymerization of CO, ethylene and propylene. Self-lubricating, impact resistance and many other excellent properties, compared with polyoxymethylene (POM) material, this material has the characteristics of low specific gravity, higher impact resistance toughness, green environmental protection and so on. The wear resistance of POK is 14 times that of POM, which is the best wear-resistant material at present, and it can be used almost permanently without change. Usually PA66 has high tensile strength, but low im...
