Waterborne polyamide and their chain extension with isocyanates to form cationic waterborne polyureas dispersions

An improved process for forming polyamide dispersions in water utilizing carbon dioxide to facilitate dispersion of the polyamide is disclosed. The polyamides are generally below 30,000 or 40,000 g/mole molecular weight when dispersed, but can be chain extended with polyfunctional species such as polyisocyanates after dispersion. The dispersions are useful in coatings, adhesives, and inks. Composites and hybrids of these other polyamides with vinyl polymers are also disclosed and claimed.

Sprint car safety block
10604187 · 2020-03-31 ·

Safety blocks can provide two points of contact for a torque tube of a sprint car if it breaks free and begins to move. During impact, safety blocks absorb and transfer energy from the torque tube to the sprint car frame located on the outer face of the safety blocks. Each face of the safety blocks can be manufactured to accommodate any surface irregularity within the sprint car frame. The safety blocks may be inserted into the sprint car from the rear of the sprint car towards the front of the sprint car.

THREE-DIMENSIONAL POROUS POLYUREA NETWORKS AND METHODS OF MANUFACTURE

Porous three-dimensional networks of polyurea and porous three-dimensional networks of carbon and methods of their manufacture are described. In an example, polyurea aerogels are prepared by mixing an triisocyanate with water and a triethylamine to form a sol-gel material and supercritically drying the sol-gel material to form the polyurea aerogel. Subjecting the polyurea aerogel to a step of pyrolysis may result in a three dimensional network having a carbon skeleton, yielding a carbon aerogel. The density and morphology of polyurea aerogels can be controlled by varying the amount of isocyanate monomer in the initial reaction mixture. A lower density in the aerogel gives rise to a fibrous morphology, whereas a greater density in the aerogel results in a particulate morphology. Polyurea aerogels described herein may also exhibit a reduced flammability.
