Abstract

The invention discloses a high temperature resistant composite calcium carbonate and a preparation method thereof, which comprises the following raw materials: calcium carbonate, polyimide, polyether ether ketone resin, perlite powder, sodium diacetate, polyester resin, xylene, diacetate Alcohol ether, n-butanol, modifying agent, and appropriate amount of water; the preparation method comprises the following steps: (1) preparing a premix for use; (2) preparing a mixed solution; (3) preparing a modifying agent; (4) Mix the premix, the mixed liquid and the modifier, stir evenly, grind, dry and crush into superfine powder. The present invention improves the production process by combining calcium carbonate with sodium diacetate, polyimide, polyether ether ketone resin, polyester resin and other materials with better comprehensive properties, and effectively increases the composition by using modifiers and the like. Excellent high temperature resistance; its production process is simple, the production cycle is short, the quality is stable, the production cost is low, and the application value is high.

Description

technical field [0001] The invention relates to the field of industrial fillers, in particular to a high-temperature-resistant composite calcium carbonate and a preparation method thereof. Background technique [0002] Calcium carbonate is an inorganic compound, CaCO 3 Commonly known as: limestone, limestone, stone powder, marble, etc., which are formed by the combination of calcium ions and carbonate ions, are an important class of functional inorganic fillers. It is easy to process and non-toxic, and can significantly improve the processing performance and physical properties of materials and reduce production costs. It is widely used in plastics, rubber, coatings, papermaking and other fields. [0003] In the application field of calcium carbonate, most of the products belong to the category of polymers. However, the surface of calcium carbonate particles is distributed with strong hydrophilic hydroxyl groups, which is alkaline, and the interface properties of organic po...
