Abstract

The invention relates to a preparation method of a high-strength graphene expandable polystyrene board. The prepared product has the mechanical strength higher than that of other existing expendable polystyrene boards. The method comprises the several steps as follows: preparing a modified graphene pre-dispersion liquid; adding an oily dispersant to prepare an oily mixed liquid; preparing graphene polystyrene particles through suspension polymerization in a reaction kettle; finally, measuring mechanical properties after molding with pre-expansion, curing and board making processes. The prepared graphene expandable polystyrene board has excellent mechanical properties, has the tensile strength 400% higher than the national standard and has the compressive strength 200% higher than the national standard. With the adoption of the method, the application of expandable polystyrene in the packaging industry is expanded, expandable polystyrene is suitable for packaging industries with higher mechanical properties, such as packaging of precise instruments, packaging of spaceflight navigation parts and the like, and the advantages of polystyrene as a packaging material are played.

Description

technical field

[0001] The invention belongs to the technical field of packaging materials, and relates to a preparation method of a high-strength graphene expandable polystyrene board. Background technique

[0002] Graphene is a carbon atom with SP 2 The honeycomb planar thin film formed by the hybrid method is closely packed with carbon atoms, which is a quasi-two-dimensional material with a thickness of one atomic layer. Because of its unique structure and excellent electrical, mechanical, optical, chemical and thermal properties, it has become a research hotspot for many people.

[0003] Expandable polystyrene (EPS) is an important packaging material. With the continuous research and development of high-end new products, people's requirements for the strength of packaging materials are also getting higher and higher. Usually, the method of improving the strength of expandable polystyrene packaging materials is mainly to increase the molecular weight of polystyrene, spe...
