Within silicone rubber formulations, aluminum hydroxide significantly impacts the product's mechanical properties, electrical performance, hydrophobicity, and flame retardancy. Years of research indicate that incorporating aluminum hydroxide fillers enhances silicone rubber's resistance to leakage, internal erosion, arcing, and flashover. However, significant differences in physical form and chemical structure between aluminum hydroxide, inorganic fillers, and the organic polymer matrix of silicone rubber result in poor affinity, limiting the amount of aluminum hydroxide that can be effectively added as a filler.

Effect of Aluminum Hydroxide Particle Size on Mechanical Properties of Silicone Rubber for Composite Insulators: Excessively fine particles fail to distribute uniformly within the silicone system, degrading mechanical properties. Conversely, overly coarse particles possess low specific surface area, also resulting in poor mechanical performance. Optimal mechanical properties are achieved only with appropriately sized particles.

Effect of aluminum hydroxide particle size on the flame retardancy of silicone rubber for composite insulators: Smaller particles make uniform distribution in the silicone rubber system difficult, reducing flame retardancy. Conversely, excessively large particles impair compatibility between aluminum hydroxide and the organic silicone rubber system, potentially diminishing flame retardancy.

Silicone rubber possesses properties such as high-temperature resistance, weather resistance, ozone resistance, corona resistance, and electrical insulation performance. In recent years, it has seen increasingly widespread application in electrical insulation systems. The development prospects for aluminum hydroxide remain promising.

Single Use

Single use is a recent emerging trend, primarily driven by safety concerns. While traditionally used flame retardants are effective, the significant hazard posed by their high smoke generation has prompted the development of single-use solutions. However, to establish aluminum hydroxide as the primary component, a series of formulation and processing challenges must be overcome. The foremost challenge is resolving the contradiction between high dosage requirements and processing difficulties.

Effective Measures for Achieving Aluminum Hydroxide Monocomponent Use

Particle Size Optimization: Similar to other powder materials, particle size is closely linked to the mechanical properties of the filled rubber. As particle size increases, both tensile strength and elongation at break improve.

Optimal Application: Within aluminum hydroxide monomer systems, the most suitable application depends on the binder when various properties achieve optimal balance.

Surface Treatment: Surface treatment is suitable for enhancing physical properties and processability (meaning uniform distribution within the rubber).
