Description

technical field [0001] The invention relates to the technical field of printing rubber rollers, in particular to a sulfonated graphene-reinforced coating rubber material for printing rubber rollers and a preparation method thereof. Background technique [0002] Printing rubber roller is a composite of elastic rubber and metal roller core processed by a certain process. It is widely used in various printing industries. At present, there are many problems in the quality of printing rubber rollers, such as poor wear resistance. Abrasion and holes often appear, seriously affecting the printing quality, so how to improve the abrasion resistance and mechanical properties of printing rubber rollers is very necessary; [0003] The raw material of graphene oxide is easy to get and the price is low. It is an ideal filler for polymer nanocomposites. After the discovery of unsupported graphene oxide paper and graphene / polymer conductive nanocomposites, an upsurge in the application of ...

Problems solved by technology

However, it has been found that the main problem in the process of preparing graphene oxide / polymer composites is that graphene oxide is easy to agglomerate, and the dispersion in the polymer is not uniform, and the state of the interface between graphene oxide and polymer Poor, ultimately leading to low comprehensive performance of graphene oxide / polymer composites, which limits its further industrial application
