| titleOfInvention | Acrylic filming agent production process |
| abstract | FIELD: polymer production. n SUBSTANCE: invention relates to processes of producing lacquer acrylic filming agents used in manufacture of masonry, road-line, and other paints. Process of invention is realized by two-step polymerization of butyl acrylate, methyl methacrylate, styrene, and methacrylic acid at ratio (40-5):(40-45):(10-14):(1-5) in toluene-ethyl acetate mixture, while portionwise feeding monomers/initiator mixture and repeatedly ageing reaction mixture. When conversion of monomers attains 82-85%, solution of butyl acrylate/styrene/methacrylic acid copolymer is additionally charged at ratio 42:57:1 dissolved in toluene/butanol (or ethanol) mixture or toluene/acetone mixture, or in toluene/ethyl acetate/ethanol/butanol mixture. Butyl acrylate/styrene/methacrylic acid copolymer is added in amount 1.77-4.0% based on concentration of principal substance. Toluene and ethyl acetate are used in proportion (0.1-1.0):1. In the first stage, 20-30% of butyl acrylate/methyl methacrylate/styrene/methacrylic acid mixture is added and, in the second stage, 70-90%. Thus obtained filming agent is characterized by high content of nonvolatile substances at rather low viscosity, high adhesion, good strength and film drying rate, low moisture absorption, high water and wear resistance. n EFFECT: improved performance characteristics of agent. n 9 cl, 4 tbl, 7 ex |
