Abstract

The invention discloses a high-barrier HDPE (high-density polyethylene) membrane production process which comprises the steps: blending of a bottom coating solution, unreeling, corona treatment, bottom coating, drying, surface coating, surface coating drying, and reeling. By adopting the manner, the high-barrier HDPE membrane production process disclosed by the invention has the advantages of good barrier property, simple production process, high chemical stability, long service life, good temperature resistance, and high membrane strength; a release member is effectively prevented from yellowing, and the problem of catalyst poisoning during production is solved.

Description

technical field [0001] The invention relates to the field of film manufacturing, in particular to a high barrier HDPE film production process. Background technique [0002] High-density polyethylene is a highly crystalline, non-polar thermoplastic resin. PE has excellent resistance to most domestic and industrial chemicals. The polymer is non-hygroscopic and has good water vapor resistance for packaging purposes. HDPE has good electrical properties, especially the high dielectric strength of the insulation, making it very suitable for wires and cables. The existing HDPE black and white two-color and other colored membranes, in the production and use of waterproof membranes, the yellow waste engine oil in the asphalt penetrates into the surface of the HDPE membrane, making the membrane yellow and affecting the appearance. At the same time, there is nitrogen in production. Catalyst poisoning caused by silicone oil process. Contents of the invention [0003] The technical...
