Abstract

CON EL PROCEDIMIENTO PARA HACER ESPUMA DE DISPERSIONES ACUOSAS DE SUSTANCIAS ORGANICAS POLIMERICAS, ESPECIALMENTE DISPERSIONES AGLUTINANTES, MATERIALES DE RECUBRIMIENTO Y AGENTES ADHESIVOS, A LAS QUE SE AÑADEN BLOQUES MIXTOS POLIOXIALCALINOS-POLISILOXANOS-POLIMERISADOS, SE CONSIGUEN FORMULAS SEMEJANTES A LA SIGUIENTE: R1O-A-[B-A-]MR1 EN LA CUAL A ES UN BLOQUE POLIOXIALCALINO, CUYA FORMULA GENERAL ES: (CNH2NO) Y EN LA CUAL N TIENE UN VALOR ENTRE 2,8 Y 4,0, E Y TIENE UNVALOR DE 15 A 100; B ES UN BLOQUE POLISILOXANO CUYA FORMULA GENERAL ES: [R2-SIO-R2]X EN LA CUAL R2 PUEDEN SER IGUALES O DIFERENTES, Y QUEDA UN RESTO ALCALINO CON 1-4 ATOMOS DE CARBONO, O UN RESTO DE FELINO, SIN EMBARGO EL 90% DEL RESTO R2 SON DE METILO, Y X TIENE UN VALOR DE 10 A 100. R1 PUEDEN SER IGUALES O DIFERENTES, Y CONSISTEN EN UN RESTO, BIEN DE AGUA O BIEN ALCALINO, CON 1-4 ATOMOS DE CARBONO, Y M TIENE UN VALOR DE 4 A 20; EN CANTIDADES DE 0,01 A 2,0 EN PESO-% SE UTILIZAN EN DISPERSIONES ESPUMOSAS MMIXTOS POLIMERISADOS.ESTE INVENTO SE MUESTRA MUY ADECUADO PARA FORMAR ESPUMA EN BLOQUES MIXTOS POLIMERISADOS. LA VENTAJA MAS IMPORTANTE DE ESTE PROCEDIMIENTO CONSISTE EN QUE ES POSIBLE LA UNION DE DISPERSIONES ESPUMOSAS EN UN FONDE POCO PROFUNDO SIN NINGUN FALLO EN LA HUMEDAD.
