Embodiment 1

[0023] The first step is to calcinate 120g of raw materials at 600°C for 3h;

[0024] Step 2 Add 2g of aluminum titanate to the slurry, keep at 90°C, and stir for 2 hours;

[0025] The third step obtains 102g product, modified calcined superfine kaolin filler.

[0026] Example 1 product application: after adding 6.4%wt of the above-mentioned filler in the PVC wire and cable material, the volume resistivity of the wire and cable material is 3.1g×10 12 Ω m, exceeding the requirements of first-class products.

Embodiment 2

[0028] The first step is to calcinate 120g of raw materials at 680°C for 2h;

[0029] Step 2 Add 3.5g of aluminum titanate to the slurry, keep at 85°C, and stir for 1.5h;

[0030] The third step obtains 103.5g product, modified calcined superfine kaolin filler.

[0031] Example 2 product application: After adding 12.0%wt of the above-mentioned filler in the PVC wire and cable material, the volume resistivity of the wire and cable material is 3.10×10 12 Ω m, exceeding the requirements of first-class products.

Embodiment 3

[0033] The first step is to calcinate 120g of raw materials at 750°C for 1h;

[0034] Step 2 Add 5g of aluminum titanate to the slurry, keep at 80°C, and stir for 1 hour;

[0035] The 3rd step obtains 105g product, modified calcined superfine kaolin filler.

[0036] Example 3 product application: After adding 17.0%wt of the above-mentioned filler in the PVC wire and cable material, the volume resistivity of the wire and cable material is 2.10×10 12 Ω·m, exceeding the requirements of first-class products.

Abstract

The invention is a manufacturing method of modified calcuination superfine kaolinsol filler, which beongs to the manufacturing technique field of inorganic material, it uses superfine slice kaolinsol or superfine kalolinsol as the material, through low temperature calcuination and organic modified process, the filler can be produced. It has the advantage of simple process, convenient in manufacturing, the temperature is low, and the electricity performance of the product is good. The product applies to PVC wire and cable; it has excellent electricity insulation. It can decrease the cost of the PVC wire and cable.

Description

technical field [0001] The invention relates to a preparation method of modified calcined superfine kaolin filler, which belongs to the technical field of preparation of inorganic materials. Background technique [0002] Kaolin is a very important non-metallic mineral. With the development of science and technology, its application is becoming more and more extensive. Mainly used in papermaking, plastics, rubber, ceramics, pigments, building materials and other industries. The yield and comprehensive economic benefits of ultrafine kaolin can be improved by exfoliation or ball milling. Patent No. 03115823.4 proposes a preparation method of ultrafine kaolin lamella material. This method processes kaolin through an exfoliation process, and can prepare ultrafine lamella kaolin with excellent properties. In addition, ultra-fine kaolin can also be produced by processing kaolin through ball milling, but its kaolin lamella structure is destroyed. [0003] Cal...
