Polysiloxane modified resol resin, moulded bodies and composites obtained therefrom and methods for producing the resin, the moulded bodies and the composites

摘要

The present invention relates to a resol resin consisting of at least one aromatic component with a phenolic OH group and at least one aldehyde component, wherein areas embedded in the resol resin matrix consisting of organically-modified polysiloxane, with said polysiloxane containing hydrocarbon groups that are at least partially bonded to said silicon in the form of non-substituted or substituted alkyl, alkenyl, aryl, arylalkyl or alkyl-aryl groups and that are not linked by covalent bonds to reactive groups of said resol resin. The invention additionally relates to molded articles manufactured from said resin, composites from a sheet material impregnated with said resin, which was subsequently hardened, as well as methods for manufacturing said resin, said molded articles, and said composites.

1. A resol resin comprising at least one aromatic component with at least one phenolic hydroxyl group and at least one aldehyde component, wherein areas embedded in the resol resin matrix comprise organically-modified polysiloxane, with said polysiloxane containing hydrocarbon groups that are at least partially bonded to silicon atoms in the form of non-substituted or substituted alkyl, alkenyl, aryl, arylalkyl or alkyl-aryl groups and that are not linked by covalent bonds to reactive groups of said resol resin, wherein more than one hydrocarbon group is bonded to at least 40 percent of the silicon atoms of said polysiloxane, wherein said resol resin further comprises at least one additive that influences the color or the mechanical properties or the flame-resistance of a product manufactured from it, and wherein said additive is a wax.
