Advantages of Modified Aluminum Hydroxide
Enhanced dispersibility
Surface modification can improve the dispersibility of ATH in the polymer matrix, reduce agglomeration, and make it evenly distributed in the substrate, which helps to improve the overall performance and stability of the material.
Improved mechanical properties
Modified ATH can improve the mechanical strength of the material, such as tensile strength and impact resistance, thereby improving the durability and structural stability of the composite material.
Improve compatibility with the matrix
Through surface modification, the hydrophilicity of ATH can be converted into lipophilicity, enhancing its compatibility in non-polar polymers (such as PP, PE). This modification can reduce the viscosity of the material and improve processing performance.
Improved flame retardant properties
Modified ATH can release water during combustion, play a cooling role, inhibit the generation of smoke, and has the advantages of low smoke and low toxicity, meeting the requirements of halogen-free flame retardant, and is suitable for strict flame retardant requirements such as electronics and construction.
Application of Modified Aluminum Hydroxide
Plastics & polymers:
Used as a flame retardant additive in electrical cables, automotive parts, and household appliances. It improves fire resistance without compromising mechanical strength.
Rubber products:
Incorporated into tires and seals to enhance fire safety while maintaining flexibility and durability.
Coatings & paints:
Added to decorative and protective coatings to provide fire retardancy, especially in public infrastructure and commercial buildings.
Construction materials:
Used in fire-resistant panels, insulation, and sealants, helping to meet stringent safety standards.
Surface Modifier Commonly Used For Ultrafine Aluminum Hydroxide
Silane coupling agent
There are more than one hundred kinds of silane coupling agents, among which the monolayer – functional group silane coupling agent is the most stable.The stability of the -functional group silane coupling agent is between steel and metal. In addition to enhancing the mechanical properties of the products, the -functional group silane coupling agent can also improve the electrical properties and moisture resistance of the products.
Zirconium coupling agent
Class zirconium coupling agent containing zirconium aluminate low relative molecular mass of inorganic polymer in the main chain of the molecule on the complexation of two kinds of organic ligand subunits, a dentate with coupling agent good hydroxyl stability, another dentate to coupling agent good organic reactions, the aluminum hydroxide superfine aluminum hydroxide powder has good modified effects.
Higher fatty acids and their salts
In the molecular structure of higher fatty acids and their salts, one end is a long-chain alkyl group, and the other end is a carboxyl group and its metal salt which can react with the surface functional groups of aluminum hydroxide.Treating ultrafine aluminum hydroxide powder with high fatty acid and its salt can improve the affinity between ultrafine aluminum hydroxide powder and polymer molecule, and improve the mechanical and processing properties of the product.
Unsaturated organic acids
Common unsaturated organic acids are: acrylic acid, methacrylic acid, cinnamic acid, etc.Generally speaking, the stronger the acid, the easier to form ionic bond, so choose more: acrylic acid and methacrylic acid.
A variety of organic acids can be used alone, can also be mixed use, treatment of alkali metal ions containing mineral ultrafine aluminum hydroxide powder, the effect is better.
Organosilicon
Macromolecule organosilicon, also known as silicon oil, is a kind of polymer which is connected with organic group on silicon atom by silicon oxygen bond chain (si-o-si) as skeleton.Commonly used are hydrogen-containing polymethylsiloxane, hydroxyl-terminated polydimethylsiloxane, etc.
