Process for vulcanizing natural rubber by using composite zinc oxide

Номер: CN116178807A
Принадлежит:

The invention provides a process for vulcanizing natural rubber by using composite zinc oxide, and relates to the technical field of natural rubber vulcanization. The process for vulcanizing the natural rubber by using the composite zinc oxide comprises the following steps: S1, adding the natural rubber into an open mill for mixing at the roller temperature of 50-60 DEG C until the roller is wrapped by a rubber material; s2, sequentially adding sulfur, a sulfur accelerator, composite zinc oxide, polyaniline nanofibers, stearic acid, sodium stearate, lignin powder, silicon carbide powder, aluminum hydroxide powder and an anti-aging agent into the open mill, mixing for 35-60 minutes, and standing for 6-10 hours to obtain a rubber compound. According to the process, the sulfur, the accelerant NS, the accelerant TMTD, the composite zinc oxide and the stearic acid are adopted to form a vulcanization system, the anti-aging agent 4020 is adopted as an anti-aging system, the mechanical property ...

Preparation method of titanate/graphite phase carbon nitride/titanium dioxide composite nanomaterial

Номер: CN116550364A
Принадлежит:

The invention discloses a preparation method of a titanate/graphite-phase carbon nitride/titanium dioxide composite nano material. The preparation method comprises the following steps: preparing a titanate nano material through a high-pressure hydrothermal method; preparing a graphite-phase carbon nitride nano material through a thermal polycondensation method; and adding tetra-n-butyl titanate, the prepared titanate nano material and the graphite phase carbon nitride material into a mixed solution of ethylene glycol and hydrochloric acid, and carrying out pressurized hydrothermal treatment to obtain the titanate/graphite phase carbon nitride/titanium dioxide composite nano material. The obtained composite product is light brown and has the advantages of stable properties, difficulty in discoloration, high degradation efficiency and the like. The method is low in cost, simple to operate, wide in parameter adjustable range and high in repeatability, and can be used for large-scale production ...
