Abstract
The present application relates to the field of molecular sieve preparation, discloses a kind of molecular sieve matrix pellet strength improver and its preparation method and application and the preparation method of molecular sieve matrix pellet, the preparation method of molecular sieve matrix pellet strength improver includes: 1) clay mineral aggregate is mixed with sodium source, and clay base material is obtained;2) after being pulverized treatment, clay base material is calcined with hole expansion aid;Wherein, the clay mineral aggregate is the mixture of halloysite, kaolinite and montmorillonite, the water content of the clay mineral aggregate is 20-40wt%, the Fe2O3 content in the clay mineral aggregate is 0.01-0.1wt%, in the mixture of the clay mineral aggregate and the hole expansion aid, the particle size of 300-600 mesh accounts for more than 98%, and the sodium source is Na2O.The strength improver prepared by the method has high viscosity and hygroscopicity, and good plasticity.
