Coating rubber material for high-polymer printing rubber rollers and preparation method thereof

Abstract

The invention discloses a coating rubber material for high-polymer printing rubber rollers. The coating rubber material is prepared from the following raw materials in parts by weight: 2-3 parts of polyoxytetramethylene glycol, 0.6-1 part of anti-aging agent SP, 1-2 parts of accelerator TTTE, 1-2 parts of saturated octadecacarbamide, 10-14 parts of graphene oxide, 6-7 parts of N-hydroxy succinimide, 10-12 parts of 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride, 7-9 parts of sulfanilic acid, 30-40 parts of styrene, 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 fiber, 50-67 parts of 20-25% ammonia water, 100-130 parts of natural rubber, 0.3-0.4 part of N,N-diethylaniline, 10-13 parts of scolecite, 1-2 parts of polycarbodiimide, 2-4 parts of polyacrylamide, 2-3 parts of phthalate and 0.8-1 part of sulfur. The polyoxytetramethylene glycol, polyacrylamide and other high-polymer raw materials are added to effectively enhance the dispersity of the raw materials in the rubber and enhance the stability of the finished product.

Description

technical field [0001] The invention relates to the technical field of printing rubber rollers, in particular to a coating rubber material for polymer 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 graphene oxide has been...

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
