Preparation method and application of weather-resistant and wear-resistant hydrophobic additive
The invention relates to the field of preparation of high polymer materials, and particularly discloses a preparation method of a weather-resistant and wear-resistant hydrophobic additive. The method comprises the following steps: 1, measuring or preparing a certain amount of fluororesin particles; 2, placing the fluororesin particles in a plasma device, treating for 1min-1h in a specific gas environment and performing surface activation treatment so as to prepare fluororesin particles subjected to surface activation treatment are prepared and form a hydrophobic additive; or carrying out chemical modification treatment on the fluororesin particles by using a chemical modifier; or putting the fluororesin particles into a plasma device, treating for 1min-1h in the specific gas environment, and carrying out surface activation treatment to prepare the fluororesin particles subjected to surface activation treatment; and using a chemical modifier. The invention also discloses an application of the weather-resistant and wear-resistant hydrophobic additive. Fluororesin particles with low surface energy are modified so that the prepared hydrophobic auxiliary agent is long in storage time, and the compatibility with a film-forming molded matter is greatly improved, so that the hydrophobic additive can be uniformly dispersed in the film-forming molded matter.
本发明涉及高分子材料的制备领域，具体公开了一种耐候耐磨疏水助剂的制备方法；包括第一步骤：量取或制备一定量的氟树脂颗粒；第二步骤：将氟树脂颗粒放置于等离子体装置中，在特定气体环境中处理1min‑1h，进行表面活化处理，制成表面活化处理后的氟树脂颗粒，形成疏水助剂；或使用化学改性剂，对氟树脂颗粒进行化学改性处理；或将氟树脂颗粒放置于等离子体装置中，在特定气体环境中处理1min‑1h，进行表面活化处理，制成表面活化处理后的氟树脂颗粒；且使用化学改性剂。本发明还公开了一种使用上述耐候耐磨疏水助剂的应用；通过改性具有低表面能的氟树脂颗粒，制成疏水助剂保存时间长，大大提高与成膜成型物的相容性而使之能均匀分散在成膜成型物质中。
