Coating rubber material for composite fiber modified printing rubber roll and preparation method of coating rubber material

Abstract

The invention discloses a coating rubber material for a composite fiber modified printing rubber roll. The coating rubber material is prepared from, by weight, 0.1-0.2 part of sodium dimercaptosulphonate, 10-14 parts of graphene oxide, 6-7 parts of N-hydroxy succinimide, 10-12 parts of 1-ethyl-(3-dimethyl amino propyl) carbodiimide hydrochloride, 7-9 parts of sulfanilic acid, 0.1-0.2 part of potassium persulfate, 0.3-0.4 part of lanthanum chloride, 2-3 parts of ethylenediamine tetraacetic acid, 1.7-2 parts of carbon fibers, 50-67 parts of 20-25% ammonia water, 100-130 parts of natural rubber, 4-6 parts of ethyl cellulose, 1-2 parts of carboxymethyl cellulose, 0.7-1 part of n-salicylanilide, 0.6-1 part of dialkyl p-dihydroxybenzene, 2-3 parts of isopropyl palmitate, 30-40 parts of styrene, 0.8-1 part of sulfur, 1-2 parts of accelerant BZ, 10-15 parts of light calcium carbonate and 1-2 parts of anti-aging agent 688. The ethyl cellulose and the carboxymethyl cellulose are added in the coating rubber material, so that the toughness of the finished rubber material is effectively improved.

Description

technical field [0001] The invention relates to the technical field of printing rubber rollers, in particular to a coating rubber compound for composite fiber modified 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 graphe...

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
