Abstract

The invention belongs to the technical field of material processing and particularly relates to a polymer nano calcium carbonate composite preparation method which enables nano particles to be scattered uniformly. The polymer nano calcium carbonate composite preparation method includes the steps: 1, preparation of nano calcium carbonate suspension liquid; and 2, preparation of composite.

Description

Technical field: [0001] The invention belongs to the technical field of material processing, and more specifically relates to a preparation method of a polymer nanometer calcium carbonate composite material. Background technique: [0002] Inorganic particle-filled polymer modification methods are usually used to prepare composite materials with specific mechanical properties, electrical conductivity, and magnetic properties. With the realization of industrial production of ultrafine particles, especially nanoparticles, the compounding of these particles with special physical and chemical properties and polymers has attracted more and more attention. [0003] Due to the small size of nanoparticles and many unpaired atoms on the surface, they have a strong ability to bind to polymers and have special effects on the physical and chemical properties of the polymer matrix. The dispersion state in the material, and the dispersion state is closely related to the preparation method...
