| With the improvement of environmental rule of law increasingly in our country and the enhancement of people's environmental awareness continuously, the environmental amicable paint is attracting many countries of the world, which has excellent performance and harmony with the environment. The water-based paint in our country was researched firstly in the 1960s and developed rapidly in the 1990s, but it had low rate of market possession. The main reason is that the water-based paint has many disadvantages such as bad water-resisted property, long film forming time, weak resistance to atmosphere and corrosion to metallic material, so it is necessary to develop the water-based paint with high property.The organic fluorine paint contains Cï¼F bond and has many particularly excellent performance. The fluorocarbon paint has developed for 38 years since 1965, which experienced four phase: heat fusing type, solvent dissolved type, normal temperature/room temperature solidifying (crosslinking) type, water-based/high solid content type. The fluorine paint firstly was used in the developed area of Asia at the end of 1980s and entered into Chinese market in the middle of 1990s. The research of the domestic fluorine paint started late. Furthermore,in the producing course of the organic fluorine paint, poisonous fluorine monomer with vinyl and monomer with vinyl and without functional group are commonly used in synthesizing fluorine polymer emulsion through emulsion polymerization, which are gas in normal temperature and take great difficulty to transportation and storage. What is more, the organic fluorine paint needs to be roasted in the high temperature, with high film forming temperature. All above limit the application and popularization of the organic fluorine paint.According to these conditions, the advantage of water-based paint and fluorine paint are combined to solve some difficult technical problem in the preparation of fluorine-containing acrylic ester copolymer. Firstly, all kinds of polymer technology are compared and the basic reaction mechanism of monomer starving semi-continuous seed polymerization is mainly discussed in this article. In order to gain optimal recipe of fluorine-containing paint and optimal experimental condition, we have mainly determined the volumes of water, the proportion of monomers, the dosage of PTFE micro-powder, the variety of initiating agent and its dosage, the variety of emulsifying agent and its dosage, the value of pH, the temperature and the velocity of stirring etc. Then, the synthetical property of fluorine-containing paint synthesized is examined, such as appearance and gel particle or gel block, solid content, micrograph of emulsion, viscidity, the remainder of monomer, minimum film forming temperature, mechanical stability, freeze-thaw stability, bin stability, thermal stability, dilution stability, calcium ion's stability and so on. To comprehend the emulsion property further, we examine various properties of fluorine-containing emulsion film according to the standard of paint, such as the color and appearance of film, the clunging, the resistance to salt water, the chemical stability, the washing fastness, the hardness, the drying time, the character of emulsion film structure through infrared spectrum and GPC and so forth. Finally, this fluorine-containing emulsion, property modified acrylic ester emulsion and pure acrylic ester emulsion are prepared, compared with the property of three kinds of emulsion and their film one another. The result proves that the fluorine-containing emulsion is better than other kinds of emulsion in the following properties: the water-resisted property, the oil-resisted property, the anti-corrosion property and so on.The fluorine-containing acrylic ester polymer emulsion is synthesized, whose main raw materials are PTFE micro-powder, BA, MMA, MAA and ST. Experiments show that the water-based paint prepared with this emulsion not only has mostly excellent properties of organic fluorine paint, avoiding all sorts of i...
