Abstract

A modified ethane-vinyl alcohol copolymer composite material and a preparation technology thereof. The modified ethane-vinyl alcohol copolymer composite material comprises: by weight, 10 to 50% of calcium sulfate, 10 to 40% of maize starch, 20 to 60%of an ethane-vinyl alcohol copolymer, 1 to 10% of a stabilizing agent, 1 to 10% of an anti-oxidant and 1 to 20% of an eleaostearic acid. The invention also comprises the preparation technology of the modified ethane-vinyl alcohol copolymer composite material. The modified ethane-vinyl alcohol copolymer composite material has good mechanical properties, a low manufacturing cost and a good biodegradability, can replace natural for utilization in the fields of indoor and outdoor decoration, building industries and the like, and opens a new approach for reduction of waste and old plastic products and improvement of a calcium sulfate comprehensive utilization ratio.

Description

technical field [0001] The invention relates to an ethylene-vinyl alcohol copolymer composite material and a preparation process thereof, in particular to a modified ethylene-vinyl alcohol copolymer composite material and a preparation process thereof. Background technique [0002] Ethylene-vinyl alcohol copolymer (EVOH) has been the most widely used high barrier material. In addition to the non-stretched film, the film of this material also has a biaxial stretching type, an aluminum evaporation type, an adhesive coating type, etc. The biaxial stretching type also includes a heat-resistant type, which is mainly used for aseptic packaging products. [0003] The barrier properties of EVOH depend on the ethylene content. Generally speaking, when the ethylene content increases, the gas barrier properties decrease, but it is easy to process. [0004] The remarkable feature of EVOH is that it has excellent gas barrier and excellent processability. In addition, it has excellent tr...
