80-120nm is suitable, the application of nano-calcium carbonate in rubber, the finer the particles, the larger the specific surface area infiltrated with the rubber, so that the dispersion of calcium carbonate particles becomes more and more difficult, especially when the surface is below 80nm, due to the surface The increase in energy is likely to cause heat generation during rubber mixing and cause sticking.

As a filler for rubber, when the moisture content of the nano calcium carbonate is lowered, the scorch time of vulcanization is shortened, which is advantageous for increasing the vulcanization speed, and is generally required to be less than 0.5%.

The effect of the pH of nano-CaCO3 in rubber applications is mainly due to its vulcanization rate. Generally, the pH value of the nano calcium carbonate is 9-10.5. If the pH value is too low, the vulcanization rate is slow and the scorch time is long, thereby prolonging the processing time and increasing the energy consumption.
