Abstract
Disclosed herein are processes for production of a cured polymeric product which processes include using rubber particles to form a rubber layer, applying liquid binder to form a bound layer from the rubber layer, and curing, whereby repetition of steps allows for formation of additional layers and ultimately production of the cured polymeric product.
Claims24
A process for producing a cured polymeric product by additive manufacturing, comprising:
- providing an additive manufacturing device comprising a source of actinic radiation, a tank capable of containing a binder, and a support structure;
- forming rubber particles into a first rubber layer upon the support structure, wherein the rubber particles comprise at least one conjugated diene-monomer containing polymer and reinforcing filler, wherein the rubber particles are in paste form, comprise uncured rubber, or are in paste form and comprise uncured rubber;
- applying liquid binder to the first rubber layer to form a first bound layer, wherein the liquid binder comprises a curable polymeric mixture and optionally a cure package;
- sequentially forming additional rubber layers upon the first bound layer and applying liquid binder to at least some of the additional rubber layers to form additional bound layers;
- and
- effecting curing by applying actinic radiation, heat, or a combination thereof to one or more of the bound layers,
- thereby producing a cured polymeric product.
