| Abstract: |
| Natural emulsion / silica hybrid liquid jet atomization is processed by high pressure spray atomization device, research on Effect of injection pressure on properties of composite materials. The results showed that the injection pressure is too large or too small can not make silica reached good dispersion in the rubber matrix, and the curing behavior and physical properties of size were not to achieve the best value; when the injection pressure is 1.5MPa, silica dispersion reached optimal quality, Mooney viscosity 、 curing properties and the main physical properties of vulcanizate, such as tensile strength, tear strength, abrasion are optimal, and the composite material is the lowest loss factor in the temperature range of 40 ~ 60. |
