Embodiment 1

[0030] In the embodiment of the present invention, a kind of preparation method of ultrafine activated clay comprises the following steps:

[0031] (1) Add modified clay and activator in deionized water, stir and ultrasonically disperse for 10 minutes in a water bath at 50°C, add borax, and stir for 5 minutes to obtain a clay emulsion;

[0032] (2) Add shell powder and sodium dodecylbenzenesulfonate to the clay emulsion, stir evenly, and after standing for 30 minutes, filter the filter residue and dehydrate the filter residue to make the water content of the filter residue 50%. According to 1h, drying until the water content of the filter residue is 1%, to obtain activated clay;

[0033] (3) Put the activated clay into the counter-jet jet mill for ultra-fine grinding until the particle size of the activated clay is 2-10 μm to obtain ultra-fine activated clay.

Abstract

The invention relates to the technical field of inorganic filling materials, in particular to a preparation method of superfine activated clay, comprising the steps of adding modified clay and an activator into deionized water, stirring under water bath for ultrasonic dispersing, adding borax, and stirring to obtain clay emulsion; adding shell powder and sodium dodecyl benzene sulfonate into the clay emulsion, stirring well, allowing standing, filtering, collecting filter residue, dewatering the filter residue, irradiating with gamma ray, and drying to obtain activated clay; micronizing the activated clay in a spray jet mill to obtain superfine activated clay. The preparation method of the superfine activated clay helps effectively improve mechanical properties and aging resistance of clay, and reduce production cost.

Description

technical field [0001] The invention relates to the technical field of inorganic fillers, in particular to a preparation method of ultrafine activated clay. Background technique [0002] Clay is very rich in reserves in our country. It mainly refers to clay that contains iron and has yellowish-brown, off-white, red-purple hues, and has good plasticity. The mineral composition is mainly montmorillonite and kaolin, which belong to the layer Crystalline aluminosilicate is an important inorganic filler. It is widely used in the filling of polymers such as plastics and rubber. With the rapid development of the composite material industry, people have higher and higher requirements for material performance. As a reinforcing filler for composite materials, the performance requirements of clay are gradually increasing. Ordinary clay can no longer meet people's needs. [0003] Studies have shown that refining the particle size of clay can effectively improve the performance of clay...
