METHOD OF PROCESSING STRUCTURIZED PHENOLIC RESIN AND ITS UTILIZATION

摘要

FIELD: utilization of phenolic resin, production of preparations used for forest protection against pests. SUBSTANCE: method involves the modification of phenolic resin properties at physicochemical treatment. Resin is heated to 80-90 C followed by natural cooling to 0 C, keeping at this temperature for 10-15 hr and heating to the room temperature. Except for, low-molecular polyethylene at concentration 15-25% is added additionally to the heavy phenolic resin, and the natural cooling composition after heating to 80-90 C is carried out to the room temperature. EFFECT: the end product is used as entomological glue composition for the forest protection against pests at temperature from -5 to +50 C.
