FIELD: chemistry.
SUBSTANCE: invention is related to method for manufacture of combined elements, which consist of one protective layer and one rigid plastic foam on isocyanate basis, between which adhesion promoter is applied. Method provides for continuous displacement of protective layer with serial application of adhesion promoter on it and initial material for rigid plastic foam on isocyanate basis. Adhesion promoter is applied by means of rotary disc installed preferably parallel to protective layer in horizontal plane or with deviation from it that does not exceed 15°.
EFFECT: produced elements have high adhesion strength.
