Abstract

The present invention relates to a preparation method of inorganic-organic high-molecular composite particle and its special-purpose equipment. The inorganic particle can be directly reacted with organic high-molecular compound in a reactor still, under the action of mechanical energy and heat energy provided by reactor still the inorganic particle is reacted with organic high molecular to make chemical linkage, and one layer or several layers of organic high-molecular membranes can be formed on the surface of the particle so as to obtain the invented hydrophobic inorganic-organic high-molecular composite particle which can have an affinity for organic high-molecular material. Its special-purpose equipment is formed from horizontal reaction still with jacket, motor and control cabinet, etc.

Description

technical field [0001] The invention relates to a preparation method and equipment for compounding inorganic-organic materials, more precisely, relates to a preparation method and special equipment for inorganic-organic polymer composite particles. Background technique [0002] Inorganic-organic polymer composite particles are widely used as additives and modifiers in rubber, plastics, and building materials, which can improve the performance of products and reduce costs. At present, the main method for preparing inorganic-organic polymer composite particles is emulsion polymerization. This method has high requirements for equipment and preparation technology, high production cost, and no special equipment, which cannot meet the needs of practical applications. The equipment used is composed of a rotary heating kiln, a mixing kettle and a collector. The equipment manufacturing cost is high, the floor area is large, the energy consumption is high, the process conditions are ...
