Abstract
<B>"PARTìCULAS ESPUMADAS DE RESINA DE POLIOLEFINA E PROCESSO DE PRODUçãO DAS MESMA"<D>. Quando deseja-se de obter partículas espumadas possuindo uma taxa de expansão alta mediante a produção de partículas espumadas de uma resina de poliolefina, há um problema referente ao fato de partículas espumadas desiguais em diâmetros celulares serem produzidas. Qualquer artigo moldado com as referidas partículas espumadas envolve uma desvantagen no sentido que o mesmo é pobre em estabilidade dimensional e seu perfil de superfície torna-se irregular. A invenção refere-se à partículas espumadas compreendendo uma resina de poliolefina como uma resina de base, onde a resina de base contem um sal metálico (excluindo sais metálicos alcalinos) de ácido bórico de uma maneira na qual o conteúdo do sal metálico de ácido bórico na resina bruta totaliza 50-50.000 ppm. Borato de zinco, borato de magnésio ou afins são utilizados como o sal metálico de ácido bórico. As partículas espumadas são obtidas através da utilização de uma resina de poliolefina contendo o sal metálico de ácido bórico para preparar partículas de resina, dispensando-se as partículas de resina em um meio de dispersão em um reservatório fechado e, ao mesmo tempo, impregnando-se as partículas de resina com um agente espumante, mantendo-se as partículas de resina em uma atmosfera aquecida e pressurizada, e então liberando-se as partículas de resina juntamente com o meio de dispersão em uma atmosfera de uma pressão inferior à pressão interna do reservatório para expandir as partículas de resina.
