Problems solved by technology

[0007] The first method is to carry out special treatment on the inner surface of the formed container product, such as fluorination or sulfonation treatment, to improve its barrier performance to organic solvents, such as the CN200410083959.2 patent, but the method of surface treatment, the investment cost High, and the fluorinating agent or sulfonating agent is toxic, which will have adverse effects on the human body and the environment
[0008] The second method is to use a multi-layer co-extrusion process to form a multi-layer structure in the container wall to improve the barrier performance. Patents such as CN201020101787.8 and CN201020625545.9 provide a multi-layer co-extrusion process to prepare high barrier properties. Polymer materials, but the above-mentioned patented production process is complex, high cost, difficult to recycle scraps, easy to prepare film products, difficult to prepare containers

Abstract

The invention discloses a preparation method of high-density polyethylene / polyamide 66 laminar barrier materials using an in-situ reactive compatibilization method. By the preparation method, compatibility between the high-density polyethylene and the polyamide 66 is improved. The high-density polyethylene / polyamide 66 laminar barrier materials comprise, by weight, 65-95 parts of high-density polyethylene, 5-35 parts of polyamide 66, 0.01-1 part of initiator, 0.1-4 parts of maleic anhydride, and 1-7 parts of montmorillonite. The high-density polyethylene / polyamide 66 laminar barrier materials are evident in compatibilization, high in interface adhesion, excellent in barrier performance, applicable to hose packing of pesticide bottle production, paint bucket and diluent bottle production, and cosmetic production or to packing films or hose packing of food production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-density polyethylene (HDPE) / polyamide 66 (PA66) laminate barrier material prepared by an in-situ reaction compatibilization method. Background technique [0002] With the development of science and technology and the enhancement of environmental protection awareness, the use of polymer materials to replace existing packaging materials is the development direction. Polymer materials occupy an increasingly important position in the packaging field. Compared with traditional packaging materials such as metal and glass It has the advantages of light weight, easy processing and molding, and not easy to break. [0003] As a general packaging material, high-density polyethylene is used in many places.
