Shandong Architecture University, Jinan 250012 HC coating Network News: Abstract: The copolymerization of epoxy resin and acrylic monomers are water-based acrylic resin from the dried epoxy Anticorrosion coating Base material, titanium-iron powder obtained by water-borne anti-corrosion pigments and efficient anti-corrosion coating. of epoxy resin, paint kind and no. of anti-corrosion paint corrosion resistance regarding the coating.
The conclusions showed that E-44 epoxy resin within the no. of 30%, titanium-iron powder and 5%, the anti-corrosion coating has great corrosion resistance and mechanical properties. Key words: anti-corrosion coating; epoxy acrylic resin; anticorrosive pigments; titanium-iron powder 0 Introduction Epoxy coatings cured film with high hardness, tough adhesion and good electrical insulation, h2o resistance, outstanding chemical resistance characteristics for example anti-corrosion coating the base fabric most commonly used. However, the use of epoxy resin was located a many shortcomings, for example curing membranes flexible enough brittleness, UV resistant, anti-yellowing performance poor, and the cost is high and the h2o of difficulties. These problems for epoxy resin, modified epoxy resin at home and abroad in recent years to improve its performance [1-8].
Effective modification is chemical modification, about 3 or more substances by chemical bonds Cooperation Used together, not only have the advantage regarding the different components, and the phenomenon of phase separation does not occur. Acrylic has good mechanical properties, great cold resistance, elasticity, flexibility and resistance to organic Solvent Performance, film performance advantages of easy adjustment, but the relatively poor corrosion resistance. This learn of molecular design, epoxy and acrylic monomer graft polymerization of water-soluble acrylic resin like a water-based epoxy anticorrosive paint formulations regarding the base material, with a tiny many efficient non-toxic anticorrosive pigment titanium-iron powder, obtained in good anti-corrosion coating products. 1 Fabrics and reagents Epoxy resin E-44, Jiangsu, Miki company; acrylic monomers, chemical pure reagents; titanium-iron powder, Shandong Shan County Special anticorrosive paint factory; zinc oxide, silicon and lead chromate, Iron oxide Red, are all created of non-residential grade talc. 2 epoxy acrylic resin First measurement regarding the epoxy resin E-44 with moderate Acetone Dissolved and transferred to a sure no.
of emulsifier and deionized h2o 3 flask, at 80 constant heat oil bath to join the 20% of acrylic acid and ester monomer and 40% of mixed emulsifier and 50% ammonium persulfate initiator, to system blue, and then gradually drops and accurate measurement of acrylic acid and ester monomers, emulsifier, while adding the remaining initiator in batches, drop about 3h subsequent to the reaction finished 2h, and then adding adaptive system for pH, ammonia to 7 ~ 8, and finally cooled to room heat the reaction system can be. 3 Formulation and properties of water-based anti-corrosion coating Shall Fillers, Dispersing agent, deionized h2o and water-based acrylic resin, epoxy resin mixture, then ground to fineness of fewer than 30 m, into the composition of other components, fully anti-corrosion coating products obtained subsequent to mixing. By GB or T1727? 1992 ways to tin film to substrate, spraying, brushing or Scratch. Reference formulation and performance test conclusions shown in Table 1, Table 2.
