The sizing material is prepared from the following raw materials in parts by weight: 0.3-1 part of methyl tin mercaptide, 2-4 parts of dodecenylsuccinic acid, 10-14 parts of graphene oxide, 6-7 parts of N-hydroxysuccinimide, 10-12 parts of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, 7-9 parts of sulfanilic acid, 30-40 parts of styrene, 0.1-0.2 part of potassium peroxodisulfate, 0.3-0.4 part of lanthanum chloride, 2-3 parts of ethylene diamine tetraacetic acid, 1.7-2 parts of carbon fibers, 50-67 parts of ammonium hydroxide having a concentration of 20-25 percent, 1-2 parts of accelerant TL, 1-2 parts of an anti-aging agent DOD, 100-130 parts of natural rubber, 2-3 parts of calcium palmitate, 6-8 parts of dioctyl sebacate, 0.6-1 part of diacetone alcohol, 1-2 parts of aluminum dihydrogen phosphate, 0.4-1 part of diallylamine, 10-14 parts of sepiolite powder, 1-2 parts of ammonium molybdate and 0.8-1 part of sulphur. The lamination adhesive sizing material has the advantages of good stability, long service life, high comprehensive performance, acid and alkali resistance, ink proofing and strong humidity resistance.

Description

technical field [0001] The invention relates to the technical field of printing rubber rollers, in particular to a long-lasting and stable 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 graphen...

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
