Hydrophobic powder as well as preparation method and application thereof
The invention relates to hydrophobic powder and a preparation method and application thereof, and belongs to the technical field of hydrophobic powder preparation. The hydrophobic powder is prepared from the following raw materials in parts by weight: 102 to 156 parts by weight of a primary mixture, 8 to 18 parts by weight of a hydrophobic agent, 5 to 22 parts by weight of hydroxyethyl acrylate, 3 to 16 parts by weight of hexadecyl trimethyl ammonium bromide, 2 to 12 parts by weight of 2-hydroxy-1-[4-(2-hydroxyethoxy) phenyl]-2-methyl-1-acetone and 20 to 60 parts by weight of purified water. The hexamethyldisilazane is added, so that the surface energy of the material is reduced, and the hydrophobicity of the product is improved; hydroxyethyl acrylate is added, a large number of hydroxyl groups are added to the hydrophobic powder, hydrogen bonds are formed between the hydroxyl groups and silicon-oxygen bonds, the hydrophobic powder is endowed with aging resistance, in the process that a system forms gel, the whole system forms a semi-intertwining net-shaped structure, the binding force between the components is increased, and therefore the hydrophobic powder has excellent toughness.
本发明涉及一种疏水粉末及其制备方法与应用，属于疏水粉末制备技术领域，所述疏水粉末包括如下重量份原料：102‑156重量份初混料、8‑18重量份疏水剂、5‑22重量份丙烯酸羟乙酯、3‑16重量份十六烷基三甲基溴化铵、2‑12重量份2‑羟基‑1‑[4‑(2‑羟基乙氧基)苯基]‑2‑甲基‑1‑丙酮和20‑60重量份纯化水。本发明加入六甲基二硅氮烷，使材料的表面能降低，提高产品的疏水性；加入丙烯酸羟乙酯，为疏水粉末添加大量羟基，与硅氧键之间形成氢键，赋予疏水粉末耐老化性能，而在体系形成凝胶过程中，整个体系形成半相互缠绕网状结构，加大了组分之间的结合力，从而使疏水粉末具有优异的韧性。
