Problems solved by technology

For the unavoidable friction, collision and bump in the process of loading and unloading and transportation, the traditional method is to thicken the packaging material to form a giant and transitional packaging, resulting in difficulty in loading and unloading, huge waste of packaging materials and consumption of resources.
The emergence of paper skins has alleviated the problem, but it is accompanied by pollution in paper mills and long recycling chains
The emergence of plastic packaging has further solved the problem of lightness, and there are also good solutions for wear resistance and high impact resistance, but solutions that combine wear resistance and high impact resistance are relatively rare

preparation example Construction

[0023] The present invention also proposes a preparation method of a POK / PCTG wear-resistant high-impact composite material, comprising the following steps:

[0024] (1) Take POK resin, PCTG resin, toughening agent, compatibilizer, lubricant, antioxidant, and wear-resistant synergist according to the requirements of the proportion and add them to the mixer for mixing, and the temperature is controlled at 45-75°C;

[0025] (2) Add antioxidant and other processing aids and continue mixing, the temperature is controlled at 55-65°C;

[0026] (3) Add the uniformly mixed material from the main feeding port of the twin-screw extruder, melt and extrude to granulate, and set the temperature of each section of the extruder to 200°C, 240°C, 2350°C, 240°C, 240°C, 245°C, head temperature 245°C, screw speed 400 rpm.

Embodiment 1

[0029] Take 10 parts of polyketone POK, 40 parts of highly transparent copolyester plastic PCTG, 4 parts of toughening agent, 2 parts by weight of compatibilizer, 0.2 part of lubricant, 0.2 part of antioxidant, 0.5 part of wear-resistant synergist share.

[0030] Since tougheners, compatibilizers, lubricants, antioxidants, and wear-resistant synergists are all routinely used substances in this field, and the physical and chemical indicators of the listed and similar substances are similar, and they are highly interchangeable, so they are no longer List and explain one by one. The preparation method is also a common method in this industry, so it will not be described repeatedly. The same below.

Embodiment 2

[0032] 35 parts of polyketone POK, 65 parts of highly transparent copolyester plastic PCTG, 14 parts of toughening agent, 5 parts by weight of compatibilizer, 0.7 part of lubricant, 0.5 part of antioxidant, and 1.7 parts of wear-resistant synergist.

Abstract

The invention provides a POK / PCTG composite packaging material with resistance to wear and high impact and a preparation method of the POK / PCTG composite packaging material. A flexibilizer, a compatilizer, an antioxidant and a wear resisting synergist which are properly proportioned are added to POK and PCTG as matrix resin materials, all the materials are mixed in a high-speed mixer, the mixtureis subjected to a series of follow-up treatment including mixing, cooling and granulation in a twin-screw extruder, then the composite packaging material is obtained, the surface of the composite packaging material has excellent wear resistance and good resistance to low-temperature impact, and the application field of POK and PCTG is expanded, especially in the aspect of high-end packaging materials.

Description

technical field [0001] The invention relates to a wear-resistant and high-impact composite packaging material, in particular to a POK / PCTG wear-resistant and high-impact composite packaging material and a preparation method thereof. Background technique [0002] With the rapid development of the logistics industry, the requirements for packaging materials are also getting higher and higher. For the unavoidable friction, collision and bump in the process of loading and unloading and transportation, the traditional method is to thicken the packaging material to form a giant and transitional packaging, resulting in difficulty in loading and unloading, huge waste of packaging materials and consumption of resources. . The emergence of paper skins has alleviated the problem, but it is accompanied by pollution in paper mills and excessively long recycling chains. The emergence of plastic packaging has further solved the problem of lightness, and there are also good solutions for ...
