Abstract

REVESTIMENTO LEVE, ISOLANTE DE SOM, PARA UMA PARTE DE CARROCERIA DE UM VEìCULO AUTOMOTOR E PROCESSO PARA SUA PRODUçãO. A presente invenção refere-se a revestimento (1) leve, isolante de som, para uma parte de carroceria de um veículo automotor, especialmente em forma de um revestimento de parede frontal leve, abrangendo uma camada de absorvente de som (1.1), uma camada amortecedora de som (1.2) essencialmente estanque a ar, diretamente unida com a camada absorvente de som, e uma camada de espuma (1.3) conectada a esta, sendo que a camada absorvente de som (1.1) é formada de um absorvente poroso, de preferência de um velo de fibras ou espuma que apresenta a uma pressão de teste de 100 Pa uma permeabilidade ao ar na faixa de 150 a 2.000 litros/m^ 2^s. A camada amortecedora de som (1.2) é formada de uma camada de pele da camada de espuma integral (1.3), com ao menos 0,5 mm de espessura, e está unida com o absorvente poroso com travamento devido a material, por espumação posterior do absorvente poroso, essencialmente sem perfuração da espuma. Descreve-se, além disso, um processo para a produção desse revestimento.
