Abstract
Sposób wytwarzania żywicy fenolowo-formaldehydowej w wieloetapowym procesie kondensacji polega na tym, że: w pierwszym etapie fenol kondensuje się z formaldehydem, przy stosunku molowym fenol: formaldehyd = 1:0,7 - 0,9, w obecności katalizatora będącego związkiem o wzorze HNR1R2, gdzie: R1 i R2 to H i/lub CnH2n+1, n=1-3, w ilości 0,001 - 0,050 mola/1 mol fenolu, w temperaturze 70 - 100°C, w czasie 10 godzin. Mieszaninę reakcyjną zatęża się do zawartości poniżej 5% wagowych wody. W drugim etapie wprowadza się olej tungowy w ilości stanowiącej 5-25% wagowych zatężonej mieszaniny reakcyjnej oraz n-butanol w ilości stanowiącej 10 - 40% wagowych zatężonej mieszaniny reakcyjnej i kontynuuje się proces kondensacji w temperaturze 100 - 130°C, w czasie 2 - 12 godzin. W trzecim etapie wprowadza się toluen w ilości stanowiącej 1 - 10% żywicy uzyskanej w drugim etapie, oraz ewentualnie butanol do uzyskania lepkości w granicach 1000 - 1500 mPa•s w temperaturze 20°C. Następnie dodaje się urotropinę i/lub amoniak do uzyskania czasu żelowania w granicach 500 - 800 s.The method of producing phenol-formaldehyde resin in a multi-stage condensation process is that: in the first stage, phenol is condensed with formaldehyde, at a molar ratio of phenol: formaldehyde = 1: 0.7 - 0.9, in the presence of a catalyst being a compound of formula HNR1R2 , where: R1 and R2 are H and / or CnH2n + 1, n = 1-3, in an amount of 0.001 - 0.050 mol / 1 mol of phenol, at a temperature of 70 - 100 ° C, for 10 hours. The reaction mixture is concentrated to less than 5% by weight of water. In the second stage, tung oil in an amount of 5-25% by weight of the concentrated reaction mixture and n-butanol in an amount of 10 - 40% by weight of the concentrated reaction mixture are introduced, and the condensation process is continued at 100 - 130 ° C, during 2 - 12 hours. In the third stage, toluene is added in an amount of 1 - 10% of the resin obtained in the second stage, and optionally butanol to obtain a viscosity in the range of 1000 - 1500 mPa • s at 20 ° C. Then urotropin and / or ammonia are added until a gel time of 500-800 s is obtained.
