Surface modification refers to the adsorption or coating of one or more layers of substances on the surface of aluminum hydroxide particles to change their surface properties and enhance their compatibility and interfacial bonding with the matrix material..
Surface modification methods are mainly divided into physical and chemical methods.:
1. Physical law:UseSurfactants such as higher fatty acids, alcohols, amines, esters and the like are subjected to surface coating treatment. These surfactants can increase the distance between the aluminum hydroxide particles, hinder the agglomeration between the particles, and improve the affinity between the aluminum hydroxide and the organic polymer. This modification method helps to improve the processing technology, improve the flame retardant performance, and enhance the impact resistance of organic polymers.
2. Chemical method:Surface modification of aluminum hydroxide with coupling agent The coupling agent molecules can chemically react with the surface of aluminum hydroxide to form chemical bonds, which are firmly bonded to the surface of aluminum hydroxide particles. Because the coupling agent molecules have affinity for organic matter, the modified aluminum hydroxide can better combine with organic polymer materials and improve the performance of composite materials.
3.Macromolecular bonding is a modification method of combining macromolecular substances with aluminum hydroxide particles by chemical bonding. This method can significantly reduce the surface tension of aluminum hydroxide particles and improve the mechanical properties of the polymer after filling. At the same time, the macromolecular bonding can also enhance the interfacial bonding force between aluminum hydroxide and the matrix material, and improve the overall performance of the composite material.
4. The modification equipment is the most critical part of the modification process, and the use of the appropriate modification machine can ensure the quality of the product.Honeycomb mill A mechanical mill, modified process is an air-swept system, is specifically designed for the production of ultrafine powders with strict requirements for particle size distribution. Simultaneously realize the grinding, drying, sorting, and surface chemical treatment of the powder, while drying and depolymerization of the wet mill filter cake and slurry. According to the diversity of materials, different materials can be used inside the honeycomb mill, which has the ability to retain the chromaticity, purity, etc., and the coating rate can reach99.2%, the activation rate was 99.8%.Very suitable for industrial mass production.

The modification of aluminum hydroxide can significantly improve its application performance in various fields. For example, in the field of flame retardancy, the modified aluminum hydroxide can play a more effective role in flame retardancy and improve the flame retardancy of the material.In the fields of plastics, coatings, polyurethane elastomers and rubber products, modified aluminum hydroxide can improve the processing and mechanical properties of materials; in the fields of food packaging materials and building materials, modified aluminum hydroxide can also meet specific safety and environmental requirements.
