Abstract

Una lechada de yeso incluye agua, un componente hidráulico que a su vez incluye estuco y un dispersante de policarboxilato. El dispersante tiene dos unidades repetitivas, donde la primera unidad repetitiva es una unidad repetitiva de ácido monocarboxílico olefínico no saturado o un éster o sal del mismo, y la segunda unidad repetitiva es un grupo vinilo o alquilo unido a un poliéter por una union de éter. La lechada puede convertirse en un panel de yeso. Reivindicacion 1: lechada de yeso, caracterizada porque comprende agua, un componente hidráulico que comprende por lo menos 50% en peso de hemihidrato de sulfato de calcio, en base al peso en seco del componente hidráulico; y un dispersante de policarboxilato que consta esencialmente de una primera y una segunda unidad repetitiva, donde dicha primera unidad repetitiva es una unidad repetitiva de ácido monocarboxílico olefínico no saturado o un éster sal del mismo, o una unidad repetitiva de ácido sulfonico olefínico no saturado o una sal de mismo, y dicha segunda unidad repetitiva tiene la formula general (1) donde R1 está representado por: la formula (2), donde R3 es H o un grupo hidrocarburo alifático de C1 a C5, R4 es H o un grupo hidrocarburo de C1 a C20, un grupo hidrocarburo cicloalifático de C5 a C8, un grupo arilo sustituido de C6 a C14 o un grupo de conformidad con la formula (3) donde R5 y R7 representan, independientemente uno de otro, un grupo alquilo, arilo, aralquilo, o alquilarilo y R6 es un grupo alquilo, arilo, aralquilo o alquilarilo divalente, p es entre 0 y 3 inclusive, m y n son, independientemente, un entero entre 2 y 4 inclusive, y x e y son, independientemente, enteros entre 55 y 350 inclusive y z es de 0 a 200 inclusive.
