Abstract

The invention discloses a bonding resin with high resistance to oxygen and water vapor. The bonding resin comprises the following raw material components and parts by weight: 60-80 parts of polyethylene grafted maleic anhydride, 3 parts of organically modified nano-montmorillonite ~12 parts, polyvinyl alcohol 8~20 parts, polyvinylidene chloride 5~15 parts, polyamide 1~7 parts, composite stabilizer 0.1~4 parts. The bonding resin with high oxygen and water vapor resistance disclosed in the present invention has excellent bonding performance under the condition of ensuring oxygen and water vapor barrier, and the processing technology is easy to control.

Description

technical field [0001] The invention relates to a bonding resin, in particular to a bonding resin with high oxygen resistance and water vapor resistance. Background technique [0002] Plastic containers have unique advantages such as light weight, good toughness, large volume, and are easy to make into various shapes and specifications, which gradually expands their application fields and are widely used in food, beverage and pesticide packaging. Simple single-layer barrier bottles such as PP, PE, and PVC have many defects, such as high permeability of oxygen and water vapor, and poor barrier performance, which greatly restricts their use in fields with high air tightness requirements. The development of squeezed barrier bottles has been paid more and more attention, and multi-layer barrier bottles are compounded with adhesive resin. In the field of multi-layer co-extrusion barrier, in order to enhance the barrier ability to oxygen and water vapor, at present, the inner and...
