Embodiment 1

[0038] 45g of maleic anhydride grafted polypropylene (MAPP) and 5g of graphene oxide (MLGO) were melt blended in an internal mixer to obtain a composite material MAPP / 10%MLGO with uniform dispersion of graphene oxide, and the blending temperature was 120 ℃~140℃, the rotation speed is 50 rpm, the blending time is 10-15min, and granulate after blending evenly;

[0039] 4g of the prepared composite material MAPP / 10%MLGO was kneaded in an open mill to form a thin film with a thickness of less than 100 μm, folded in the same direction and then kneaded repeatedly for about 5 times. The kneading temperature was 148°C. Oriented graphene oxide composite film material with a thickness of about 40 μm;

[0040] Stack four films, heat them to 120°C in a flat vulcanizer, apply 10MPa, keep for 2min, and after cooling, a MAPP / 10%MLGO sheet of about 160μm is obtained.

[0042]45g of maleic anhydride grafted polypropylene (MAPP) and 5g of graphene oxide (MLGO) were melt blended in an internal mixer to obtain a composite material MAPP / 10%MLGO with uniform dispersion of graphene oxide, and the blending temperature was 120 ℃~140℃, the rotation speed is 50 rpm, the blending time is 10-15min, and granulate after blending evenly;

[0043] 4g of MAPP was kneaded in an open mill to form a film below 100 μm at a temperature of 150 °C; 4 g of the prepared composite material MAPP / 10%MLGO was kneaded in an open kneader to form a film below 100 μm. Two pieces of 2g MAPP film and 1g MAPP / 10%MLGO film are stacked in a "sandwich" structure (the MAPP film is the inner and outer layers, and the MAPP / 10%MLGO film is the middle layer), and they are kneaded in an open mill to form The film below 100 μm is folded in the same direction and then kneaded repeatedly for about 10 times. The kneading temperature is 148°C, and the graphene oxide composite film material MA...

Abstract

The invention discloses a graphene oxide composite film material, and a preparation method and an application thereof. The method comprises the following steps: carrying out melt blending on maleic anhydride grafted polypropylene and graphene oxide to obtain a graphene oxide uniformly-dispersed composite material, adding the composite material into an open mill, and carrying out open milling and repeated open milling treatment to prepare the graphene oxide composite film material having fixed orientation. The graphene oxide composite film material has certain orientation, and can effectively prolong the path of small molecules passing through a polymer film, so a graphene oxide composite film has a high barrier performance; and the maleic anhydride grafted polypropylene used as a matrix material is used in the barrier layer of an oil tank, and has good cohesiveness with inner layer polypropylene and outer layer nylon, and is hopeful to substitute a bonding layer, so the layer number ofthe fuel tank is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of graphene oxide modified materials, in particular to a graphene oxide high-barrier nanocomposite material and its preparation method and application. Background technique [0002] With the continuous improvement of environmental protection and safety requirements, the barrier performance requirements of fuel tanks in various countries are becoming more and more stringent. Since the pure high-density polyethylene single-layer fuel tank can no longer meet the current barrier performance standards, modified high-density polyethylene fuel tanks and multi-layer plastic fuel tanks have emerged. [0003] Existing multi-layer plastic fuel tank materials include: inner layer polypropylene, first adhesive layer, barrier layer ethylene-vinyl alcohol copolymer, second adhesive layer and outer layer of high-strength nylon 6 or Nylon 66. However, the ethylene-vinyl alcohol copolymer used as a barrier layer restricts the develop...
