Abstract

A silane cross-linked high-strength polymer film orientated by stretching has at least one layer of silane cross-linked polymer, and is prepared through stretching unidirectionally or bidirectionallyfor orientation, hydrolysis in wet and hot condition, and condensation and cross-linking reaction. It has high concave-convex reinforcing ribs for higher tension strength. Its advantages are high resistance to ageing and cracking, high strength and long service life.

Description

Technical field: [0001] The present invention relates to a polymer film, and more particularly to a silane crosslinked stretch oriented high strength polymer film. Background technique: [0002] High molecular polymers are extruded into films (sheets) through melt processing, and the products can be produced after uniaxial stretching or bidirectional stretching orientation at a suitable temperature range above its glass transition temperature and below the viscous fluid state temperature. The tensile strength is several times or even ten times higher than that of the original unstretched product, and it can also improve and improve other properties of the polymer film (sheet), such as modulus, elongation at break, impact strength, crack resistance, resistance Foldability, as well as thermal, electrical, optical, aging resistance and other properties of products, people use this processing characteristic of polymers to prepare various packaging films, industrial films and eng...
