| abstract | 1. METHOD OF CONTINUOUS PREPARATION OF PRESS-MATER1 {ALOV based on phenol-formaldehyde resins of the novolac and rezol types by polycondensation of a resin from phenol or its homologues with formaldehyde in the form of its aqueous solution in the presence of an appropriate catalyst when heated, mixing the resin and mixture of bulk solids (filler, hardener, dye), homogenous. the plasticization of the resulting press mass, vacuum drying followed by granulation or grinding of the press material obtained. This is distinguished by the fact that, in order to intensify the process, improve the quality of the press material obtained, increase the stability of its properties, reduce raw material losses and reduce harmful emissions to the atmosphere, the polycondensation of phenol and formaldehyde is first carried out at 140-180 ° C under a pressure of 16-25 MPa for 1-6 minutes in the presence of an appropriate catalyst, then onto the resulting aqueous emulsion resin cooled, to 80- 8.4 ° C and distributed in a thin layer, apply a mixture of bulk components at atmospheric pressure, after which they are mixed, homogenized and plasticized for 0.5-1.5 minutes, gradually raising the temperature to 130-160 ° C and pressure up to 20-30 air pressure, vacuum drying at an instantaneous decrease in pressure, heat treatment at 80-120 ° C and granulated masses with a temperature of 85 + 3 ° C. 2. The method according to claim 1, characterized in that, in order to obtain novolac press materials, phenol, formaldehyde and catalyst are taken in a weight ratio of 100: 26-32: 0.4-0.6.4: ^ 4 ^ SLO9 |
