Process for manufactuing a filled polymeric materials with modified filler particles
View Patent ↗The invention pertains to filler modified with functional particles in a dry-blending process through collisions of sufficient energy to bound, adhere, or otherwise associate the pigment particles to the filler, and a filled polymeric material manufactured with the modified filler.
1. A process for manufacturing filled polymeric materials comprising: mixing modified filler particles comprising filler particles blended with discreet functional particles in a high energy mixer until said discreet functional particles are bound to said filler particles and remain associated during manufacturing steps employed in manufacturing filled polymeric materials during liquid prepolymer processing, with a liquid prepolymer mixture, and curing the prepolymer mixture.
2. The process of claim 1 wherein the high energy mixer is a high shear blender.
3. A process for manufacturing filled polymeric materials comprising: mixing modified filler particles comprising filler particles blended with discreet functional particles in a high energy shaker until said discreet functional particles are bound to said filler particles and remain associated during manufacturing steps employed in manufacturing filled polymeric materials during liquid prepolymer processing, with a liquid prepolymer mixture, and curing the prepolymer mixture.
4. The process of claim 1 wherein the prepolymer mixture is an acrylic.
5. The process of claim 4 wherein the filler particle is alumina trihydrate.
6. The process of claim 5 wherein the pigment particle is carbon black.
7. The process of claim 5 wherein the pigment is an iron oxide.
