Description
Technical Field
The invention relates to the technical field of cement additives, in particular to the field of IPC (IPC) 04, and more particularly relates to a synthetic cement raw material additive, a preparation method and application thereof.
Background
Cement is one of the most important basic raw materials in building materials, and the cement production process comprises the production links of 'two grinding and one burning', namely raw material grinding, kiln returning calcination and clinker grinding, wherein raw materials mainly comprise lime, clay, mineralizer and correction raw materials, and the raw materials are crushed, ground and mixed into cement raw materials according to a specific proportion. As a process auxiliary agent in the processing process of the cement raw material, the cement raw material auxiliary agent can also obviously improve the mixing uniformity of raw material particles, and excite the hydration activity of the mixed raw materials, thereby improving the service strength of cement at each age. Meanwhile, the method can effectively improve the combustibility of the cement raw material by reducing the coarse particle content, improving the structure of ore materials and improving the high-temperature reaction activity of raw material components in the grinding stage of the cement raw material, thereby reducing the energy consumption of the subsequent clinker sintering.
At present, most of existing cement raw material additives are directly purchased chemical waste liquid or are prepared by simply mixing industrial raw materials, so that the usage amount of the cement raw material additives cannot be determined and the effect is unstable. CN114477844B discloses a cement raw material grinding aid, a preparation method and application thereof. The cement raw material grinding aid provided by the invention is prepared from the following components in percentage by mass: 10-25% of organic acid salt; 11% -24% of polymeric ester; 9-16% of polyalcohol; 2% -5% of rare earth stabilizer; 45-60% of deionized water. The prepared cement raw material grinding aid can reduce grinding energy consumption and clinker burning coal consumption, but has insufficient performance, and the required addition amount of the cement raw material grinding aid is higher in actual use; CN113800796a discloses a cement raw material auxiliary agent and a preparation method thereof, the raw material composition comprises: 10 to 17 percent of raw material decomposition accelerator, 13 to 16 percent of coal saving agent, 6 to 9 percent of grinding aid reinforcing agent, 10 to 14 percent of desulfurization active agent and 0.1 to 0.3 percent of dispersing agent; the balance of water, and the total amount is 100 percent. The method has the advantages of good energy-saving, coal-saving, yield-improving and reinforcing effects, durable and high-temperature-resistant effect, more convenient liquid use and more environment-friendly desulfurization effect, but cannot ensure that the prepared raw material auxiliary agent can effectively improve the quality of cement clinker at the same time, so that development can obviously improve the grinding efficiency of cement raw material, effectively improve the calcination performance of cement additive auxiliary agent raw material and ensure the quality of cement clinker.
