Wiekszosc farb chemoodpornych (chlo- rokauczukowe, winylowe) miedzy innymi i farby epoksydowe po utwardzeniu w .pokojowej tempe¬ raturze, pomimo wielu zalet, nie zapewniaja nale¬ zytej ochrony w przemysle chemicznym, szczegóil- nie w zakresie podwyzszonych temperatur (powy¬ zej 80°C).Dobra odpornoscia zarówno na czynniki chemicz¬ ne jak i na dzialanie podwyzszonej temperatury odznaczaja sie fairiby poliuretanowe. Sa one jednak bardzo kosztowne i trudno dostepne i z tego wzgle¬ du nie moga byc iSitosowane w szerszym zakresie.W przypadkach, w których mozna stosowac utwardzanie powloki w temperaturach piecowych 150—180^C szereg farlb ze spoiwem z zywic sztucz¬ nych np. epokisypoMarmdowych zapewnia dobra o- chrone przed korozja w warunkach przemyslu chemicznego.

Xli. 1964 48748 Ki BI3LIG7KK .- '¦ Urzed v ¦¦ -.lc "iT'jvjegol MKP C09 UKD Inventor: mgr inz- Jerzy Gderej Patent owner: Central Laboratory of Fossil Chemical Raw Materials, Warsaw (Poland) Chemical and temperature-resistant paint Enamels and epoxy paints, containing epoxy resins as binders, are used to protect metal and concrete devices against the corrosive effects of electrolytes and various ohemicals involved in technological processes. Most of the chemical resistant (chlorinated rubber) paints, inter alia, vinyl, vinyl, and epoxy paints after curing at room temperature, despite many advantages, do not provide adequate protection in the chemical industry, especially in the field of elevated temperatures (above 80 ° C). Good resistance to both chemical agents polyurethane fairings are also characterized by the effect of increased temperature, but they are very expensive and difficult to obtain and therefore cannot be used in a wider In those cases where the coating can be cured at oven temperatures of 150-180 ° C, a series of paints with a synthetic resin binder, eg epoxy-resin, provide good corrosion protection under the conditions of the chemical industry. In the case of curing in noirless conditions, the paint is resistant to chemical and mechanical influences. The paint according to the invention contains epoxy resin and a modified coumarone resin. The binder for this paint is obtained by dissolving the resin in a mixture of solvents. epoxy and coumarone resin. The resulting solution of both resins is further processed into paint by adding pigment, a plasticizer and a hardener. Most preferably, an epoxy resin having an epoxy number of 0.18-0.22, the so-called "Bpidian 1", and a purified coumarin resin with a softening point of 110-120 ° C., mixed in a ratio of 3: 5, are used. The paint coating according to the invention, hardened under normal conditions, shows a good mechanical resistance at temperatures up to 105 ° C and chemical resistance to the corrosive effects of aqueous salt solutions at this temperature.
