Method of manufacturing objects from a polyurethan-binder and a cellulosic material

摘要

Moulded products based on polyurethane binders and cellulosic material are obtained by compression moulding a mixture of foam-forming two-component polyurethane adhesive(s) and cellulose-containing material in the form of strips (preferably with a thickness of 0.4-0.8 mm, a length of 100-250 mm and a width of 15-25 mm). A method for the production of moulded products based on (A) polyurethane binders and (B) cellulose-containing material, in which (A) is a foam-forming 2-component polyurethane adhesive, (B) is in the form of strips with a thickness of 0.3-1.5 (preferably 0.4-0.8) mm, a length of 80-300 (preferably 100-250) mm and a width of 10-45 (preferably 15-25) mm, and the two components are bonded together under a pressure of 0.1-15 (preferably 1-10) MPa. An independent claim is also included for moulded products (I) obtained by this method.
