Application of Modified Kaolin

Application of Modified Kaolin

After being modified, kaolin has improved its chemical cross-linking with organic polymer raw materials, improved its dispersibility, and improved the reasonable cross section for bearing external loads, thus improving the Structural mechanics properties of organic polymer raw materials. At the same time, it has greatly improved the versatility of raw materials and expanded the application scope of kaolin. The application of modified kaolin is very common, especially in the fields of building coatings, plastics, vulcanized rubber, etc., occupying a certain influence.

Application of Modified Kaolin in Architectural Coatings

In the coating industry, there are two types of kaolin that are often used: one is water cleaning of extremely fine kaolin, and the other is calcination of extremely fine kaolin. Because the modifying agent of modified kaolin has high-quality properties such as high and low temperature resistance, UV light resistance, air oxidation dissolution resistance, and insulation, combined with the organic chemical characteristics of calcined kaolin, it can be used in weather resistance, high temperature resistance, insulation, protective building coatings, and interior wall coatings, and can have certain effects on the unique performance of this product. Applied in other architectural coatings, it can also have very good effects on improving the quality of its products.

Application of Modified Kaolin in Plastics

Kaolin can replace high-quality CaCO3 as a filler for plastics such as polyethylene, polypropylene, polyester, polyester, urea formaldehyde resin, etc. in the plastic industry production, and is used for the production of plastic water pipes, plastic wooden floors, etc.

Kaolin as a filler for plastic can improve the glossiness of the plastic surface, improve specification accuracy, and resist solvent corrosion. Especially when kaolin is used as a filler for high insulation wire plastic, it can increase its resistance, which is unparalleled by other inorganic fillers. The application of modified calcined kaolin in other plastic products can improve its impact compressive strength, reliability, and thermal deformation temperature, while also increasing the amount of filling material and controlling costs. In thermosetting plastics, modified kaolin is particularly reasonable for improving the thermal expansion coefficient, tensile strength, and strain rate of plastics; In thermosetting plastic, modified kaolin has the effect of improving the plastic and preventing chemical fiber "frost" and exposure on the surface of the mold.

Application of 3 modified kaolin in vulcanized rubber

Kaolin as a filler can improve the grade of rubber and plastic products. This is because after adding powdered kaolin into vulcanized rubber, organic chemical polymer Inorganic compound composite material is produced, which can improve the physical properties of rubber and plastic products. How to improve the Structural mechanics compressive strength, wear resistance, corrosion resistance, reliability of rubber and plastic products, and improve the production and processing performance of plastic particles. While improving performance, it can significantly reduce the cost of rubber and plastic products and increase economic benefits.

After many years of product development, the surface modification of kaolin has achieved fruitful results, especially in the reinforcement of vulcanized rubber layers with silane coupling agent surface modified kaolin.
