Aqueous dispersions, a process for their preparation and the use of the dispersions as sizing agents. |
摘要 |
<p>Aqueous cationic or anionic dispersions of rosin and certain synthetic sizing agents, carbamoyl chlorides, ketene dimers or acid anhydrides. The particles in the dispersed phase contain a mixture of rosin and synthetic sizing agent and the dispersions are prepared by homogenisation of a homogeneous mixture of the rosin material and the synthetic sizing agent in the presence of a dispersing agent. The dispersions are used as sizing agents in the production of paper, paper board, board and similar products. </p> |
