三元催化清洗剂配方>稀疏编码

无皂乳液聚合是一种较为新颖的乳液聚合技术。含氟聚合物的无皂乳液聚合是以水为分散介质的，因此避免了有机溶剂涂料中的有机溶剂对环境的污染和对人类的危害，而且耐腐蚀性较强。水性涂料中的水不会造成环境污染等问题，而且生产成本也不高，所以水基涂料是环保性涂料发展的很重要方向。

本论文分四个部分。第一部分，介绍了无皂乳液聚合研究进展，主要讨论了无皂乳液聚合的成核机理、稳定机理、增长机理，影响无皂乳液聚合稳定性的因素。第二部分，主要是实验过程，系统的研究了单体、乳化剂和引发剂的选择及配比以及聚合温度、聚合时间对其单体总转化率、乳液性状、粒径及稳定性等主要性能的影响，通过设计对比试验出反应的最佳配比。第三部分，主要是对试验结果的讨论和分析，确定最佳的反应温度、时间和单体配比、乳化剂与引发剂的用量，对聚合物产品的表征和性能的测定。第四部分，得出本次研究的结论。

ABSTRACT Soap-free emulsion polymerization is novel new technology. Fluoropolymer-free emulsion with water as the dispersion medium, to avoid organic solvents in the organic solvent coating environmental pollution and harm to humans, but relatively strong corrosion resistance. Water-based paint will not bring the water pollution problems, and cost of production is not high, so water-based paint is the development of environmentally friendly coatings is very important direction.

The thesis is divided into four parts. The first part, introduced free emulsion polymerization progress, mainly discussed the soap-free emulsion polymerization nucleation mechanism, stability mechanism, growth mechanism, influencing factors in the stability of emulsion polymerization. The second part, an experimental process, the system of the monomer, emulsifier and initiator of the selection and ratio and polymerization temperature, polymerization time on the total conversion rate of monomer, emulsion characteristics, particle size and stability of other major performance, by designi

ng tests to find the optimum contrast ratio. The third part, mainly for the discussion and analysis of test results to determine the optimum reaction temperature, time and monomer ratio, the amount of emulsifier and initiator, the polymer product characterization and determination of properties. The fourth part, the conclusions drawn in this study.

Key words: emulsion polymerization, CTFE, hydroxyl butyl vinyl ether, solid content, particle size.
