Abstract

Inventia se refera la o compozitie fonoizolatoare din praf de piele, microporos si/sau macroporoasa, care este indicata a fi folosita în stare întarita sub forma unor placi sau straturi subtiri pentru captusirea masinilor sau instalatiilor zgomotoase, precum si ca element de constructie. Datorita greutatii volumetrice reduse a placilor si straturilor realizate din aceasta compozitie din praf de piele, ele sînt indicate si ca elemente de perete fonoizolatoare. Compozitia fonoizolatoare din praf de piele cu continut de rasina sintetica exprimata în % greutate este constituita din circa 1...17%, de preferinta 4...7%, praf de piele de origine animala cu o greutate volumetrica cuprinsa între 0,05 si 0,08 g/cm3, cca 75...85%, de preferinta 82% rasina fenolformaldehidica sau cca 40...55% de preferinta 45...50% rasina ureo-formaldehidica si împreuna cu aceasta din urma, eventual cca 10...15%, de preferinta 11...14%, uree si/sau cca 5...7%, de preferinta 5%, rasina furanica modificata, apoi eventual cca 1...4%, de preferinta 2...3%, agenti de umectare si/sau eventual cca 1...4%, de preferinta 2...3% agenti de spumare si cca 5...8%, de preferinta 5...6% catalizatori acizi, de preferinta acid fosforic de concentratie 10% si apa în cantitateanecesara pentru a se ajunge la 100% în greutate.
