| titleOfInvention | Particle foam stabilizer and preparation method and application thereof |
| abstract | The invention discloses a particle foam stabilizer, and a preparation method and application thereof. The particle foam stabilizer comprises hydrophilic solid particles with the particle size of 0.1-5 mu m, and hydrophobic molecular chains are modified on the surfaces of the hydrophilic solid particles through physical adsorption. The preparation method comprises the following steps: adding hydrophilic solid particles into an ethanol-water solution to prepare a solid particle suspension; then adding a modifier containing a hydrophobic molecular chain, and stirring to modify the hydrophobic molecular chain to the surface of the hydrophilic solid particles; and finally, carrying out suction filtration and separation on the obtained product, and drying the solid-phase material to obtain the particle foam stabilizer. The particle foam stabilizer can effectively improve the foam stability, and has the advantages of good stability, convenient preparation, no pungent smell and environmental protection; the particle foam stabilizer is used in a polyurethane foaming coating, and can replace the traditional ammonium stearate foam stabilizer on one hand, and on the other hand, solid particles can also serve as a filler or a functional auxiliary agent of the polyurethane foaming coating, so that the performance of the coating is improved, and meanwhile, the production cost is reduced. |
