Abstract

Perfeccionamientos en la preparación de lacados de cochuración, caracterizados porque se hace reaccionar una base de mezclas de lacas formadas por (A) 40 a 94% en peso de resina alquídica que contiene grupos carboxilo y grupos hidroxilo -con un contenido en aceite de hasta un 40% en peso- o un poliéster libre de aceite con un índice de acidez de 1 a 100, un índice de hidroxilo de 30 a 400 y un peso molecular medio comprendido entre 400 y 10.000, (B) 5 a 40% en peso de resina de aminoplasto, (C) 1 a 20% en peso de diluyente reactivo y (D) 0 a 35% en peso de un disolvente orgánico como diluyente de la reacción, con un aducto de un compuesto hidroxilo, con al menos dos grupos hidroxilo por molécula y una lactama, en una proporción molar lactama/compuesto hidroxilo de n:1, donde n puede tomar un valor de 1/20 hasta 10, obteniéndose el aducto mediante disolución o fusión conjunto de la lactama y el compuesto hidroxilo a una temperatura de 40 a 150ºC, y a continuación amasado durante aproximadamente 1 hora, y se efectúa la reacción hasta una película de laca endurecida mediante cochurado a una temperatura comprendida entre 80 y 260ºC.
