畢業(yè)設計說明書中文摘要

本文通過細乳液聚合法，成功地制備了彩色墨粉用PYl7/PE蠟/電荷調(diào)節(jié)劑/苯丙樹脂四元復合乳膠粒子。實驗對乳化工藝進行優(yōu)化，并采用透射電子顯微鏡（TEM）、激光粒度分析儀、熱重分析儀（TG）等對樣品的形貌、粒度分布、熱性能等進行了表征。研究了乳化劑的用量、蠟的用量、乳化轉(zhuǎn)速的選擇、引發(fā)劑的種類等對產(chǎn)品性能的影響。透射電鏡圖表明細乳液聚合法成功地將多組分包覆于樹脂基體內(nèi)。隨著乳化劑的用量增多，會使乳膠粒子粒徑減小。蠟的用量對乳膠粒子粒徑影響不大，但過多會降低乳液穩(wěn)定性。隨著乳化速度的加快，乳膠粒子的平均粒徑稍有下降，乳化速度過慢或過快都會降低乳液穩(wěn)定性。

Title   Research on the Preparation of Multicomponent     

 Nano Composite Latex Particles Used as Color Toner

Abstract

In this paper PYl7/ PE wax/styrene acrylic resin composite latex particles were prepared successfully by the mini-emulsion polymerization. The emulsification process was optimized. The particle size and the particle distribution of composite latex particles were measured by the particle size analyzer respectively, the morphology of the latex particles was studied by transmission electron microscopy (TEM), and the thermal properties of the composite latex particles were analyzed by thermal gravimetric analyzer (TG). The effects of the amount of emulsifier, the quantity of wax, the emulsification speed and the choice of initiator species on the products were studied. The SEM results indicate that the multicomponent component were successfully encapsulated in the polymeric resin matrix using the emulsion polymerization. With the increase of the amount of emulsifier, the size of the latex particles will decrease. The amount of wax has little effect on the size of latex particles, but too much will decrease the stability of latex. The average size of latex particles will decrease slightly with the speed of emulsification, and the emulsion stability can decrease when the speed is too slow or too fast.
