Influence of Aluminum Hydroxide Particles on the Properties of Modified Unsaturated Polyester
The performance of the modified unsaturated polyester was improved by aluminum hydroxide filler in the research. Studies found that the viscosity of the resin system, mechanical properties, thermal stability and electrical insulativity of final materials were affected by the filling content and particle sizes of aluminum hydroxide directly. With proper particle diameter and filling content, aluminum hydroxide particles could apparently improve the mechanic property, thermal stability and electrical insulativity of corresponding materials in sone extent, meanwhile the viscosity of the resin system would keep low. The mechanism of the influence of aluminum hydroxide on the performance of modified unsaturated polyester was studied by the fracture morphology of samples scanned by scanning electron microscopy.
