Abstract

The invention discloses a nanometer functional material composition. The nanometer functional material composition comprises the following raw materials in parts by weight: 30 to 50 parts of modified nanometer bentonite, 10 to 20 parts of nanometer wollastonite powder, 5 to 10 parts of nanometer calcium carbonate, 20 to 30 parts of medium liquid and 1 to 5 parts of a viscosity reducer. According to the nanometer functional material composition, the nanometer wollastonite powder, the nanometer calcium carbonate and other raw materials are combined, the modified nanometer bentonite is modified through variable temperature and active liquid, and the active performance of a bentonite material is improved; the bentonite is of a lamellar structure, so bonding between the raw materials can be blocked, and therefore, the dispersing capacity of a product is improved; and an ammonium sulfate solution in the viscosity reducer is matched with Tween 60, so the raw materials can be further subjected to repulsion treatment, and the dispersing capacity of the product is further improved.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a nanometer functional material composition and a preparation method thereof. Background technique [0002] A dispersant is a chemical that is added to water to increase its ability to remove particles. The function is to use the wetting and dispersing agent to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modify the surface properties of the pigment particles, and adjust the mobility of the pigment particles. There are few nano-material combinations in the market. Dispersants, based on this need to study treatment. [0003] Due to the small particle size of the existing nanomaterials, there is a ball effect, and the combination and dispersibility of the raw materials is poor, which leads to the unity of the raw materials, and the reaction reduces the overall performance of the functional material....
