AMINOPLAST MOLDING COMPOUNDS FOR PRODUCTS EXHIBITING AN IMPROVED FLEXIBILITY AND AMINOPLAST PRODUCTS EXHIBITING AN IMPROVED FLEXIBILITY

摘要

The invention relates to aminoplast molding compounds that are comprised of mixtures consisting of meltable 20 to 1000-ring polytriazine ethers, in whic h the triazine rings are primarily linked by binding links of the -NH-CHR2-O-R 4- O-CHR2-NH- and -NH-CHR2-NH- type, whereby: R2 = H, C1-C7 alkyl; R4 = C2-C18 alkylene, -CH(CH3)-CH2-O-C2-C12-alkylene-O-CH2-CH(CH3)- , -CH(CH3)-CH2- O-C2-C12-arylene-O-CH2-CH(CH3)-, -[CH2-CH2-O-CH2-CH2] n -, -[CH2- CH(CH3)-O-CH2-CH(CH3)] n -, -[-O-CH2-CH2-CH2-CH2-]n-, -[(CH2)2-8-O-CO-C6- C14-arylene-CO-O-(CH2)2-8-]n -, -[(CH2)2-8-O-CO-C2-C12& lt;/SB>-alkylene- CO-O-(CH2)2-8-]n -, in which n = 1 to 200. The aminoplast molding compounds are also comprised of sequences containing siloxane groups, sequences based on the alkylene oxide adducts of melamine, phenol ether sequences based on bivalent phenols and diols, and these compounds can contain up to 50 % by ma ss of additional reactive polymers of the ethylene-copolymer, maleic anhydride- copolymer, modified maleic anhydride-copolymer, poly(meth)acrylate, polyamid e, polyester and/or polyurethane type, up to 75 % by mass of fillers, up to 20 % by mass of diols, and up to 5 % by mass of stabilizers, UV absorbers and/or auxiliary agents. The invention also relates to aminoplast products that exhibit an improved flexibility such as panels, pipes, profiled pieces, coatings, foam materials, fibers or injection-molded parts, which can be produced by thermoplastic processing the inventive molding compounds. The aminoplast molding compounds can be processed according to conventional melt processing methods and can be used as hot-melt adhesives and for producing panels, pipes, profiled pieces, injection-molded parts, fibers and foam materials. The aminoplast products, which exhibit an improved flexibility while meeting high requirements with regard to flame resistance and heat resistance, are used in the construction industry, mechanical engineering, automotive industry and fire-protection engineering.
