Abstract

The invention discloses micro-nano composite particles and a preparation process thereof. The micro-nano composite particles are characterized in that nano and sub-nano particles with diameters smaller than micropore diameters of the porous micro-nano particles are inserted into the porous micro-nano particles to form three-dimensional porous and / or spiny micro-nano composite particles; the single-pore embedding quantity of the three-dimensional porous and / or spiny micro-nano composite particles is 1%-100% of the pore volume. The high-speed airflow kinetic energy embedding preparation processis easy to operate, and the prepared micro-nano composite particles have good dispersibility, are not easy to agglomerate, and can be applied to polymers and polymer products. The micro-nano compositeparticles have good reinforcement effect in rubber and rubber products, show excellent mechanical properties, and show synergistic promotion effect of reinforcement, low heat generation and wet skidresistance in tire rubber.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a novel micro-nano composite particle and its preparation process and device. Background technique [0002] At present, micro-nanoscale (10-1000nm) particles have already played an important role in modern industry, medicine, bioengineering and other fields. There are obvious surface interactions between the particles and the polymer matrix. Therefore, the performance of the material can be improved to a certain extent by selecting the appropriate particles and polymer resin matrix and using a certain material composite process. [0003] The shape of particles directly affects the cohesiveness, mechanical strength, transparency and other properties of materials, and is directly related to the compatibility of fillers and matrix in composite materials and the effective dispersion of nanometer and sub-nanometer particles. Therefore, most studies have focused on how to obtain...
