Abstract

"ADESIVO DE FUSãO A QUENTE NA FORMA DE UM GRANULADO". Para aperfeiçoar em adesivo de fusão a quente a capacidade de manuseio também após armazenagem em temperatura elevada e sob pressão, propõe-se um adesivo de fusão a quente na forma de um granulado com pelo menos uma camada externa (casca) e uma composição não adesiva e com um núcleo envolvido pela mesma do adesivo de fusão a quente, sendo que a camada externa contém o seguinte componente: 1. 10 até 25 partes, em peso, de cera de poliolefina, especialmente cera de polietileno e cera de Fischer-Tropsch como agente de separação, 2. 1 até 5 partes, em peso, de álcoois de açúcares, especialmente sorbitol e manitol como formadores de películas e 3. 0,05 até 0,25 partes, em peso, de um umectante ou de um desespumante, bem com eventualmente 4. um aditivo tal como por exemplo, uma resina. O núcleo do adesivo de fusão a quente é preparado, de preferência, pelo processo de granulação subaquático conhecido, sendo que a camada externa é obtida pelo tratamento com um agente refrigerante, que contém pelo menos os componentes 1 e 2 da camada externa."HOT FUSION ADHESIVE IN THE FORM OF A GRANULATE". To improve the handling capacity of hot melt adhesives even after storage at elevated temperature and under pressure, a hot melt adhesive in the form of granules with at least one outer layer (peel) and a non-adhesive composition is proposed. and with a core surrounded by hot melt adhesive, the outer layer containing the following component: 1. 10 to 25 parts by weight of polyolefin wax, especially polyethylene wax and Fischer-Tropsch wax as separating agent, 2. 1 to 5 parts by weight of sugar alcohols, especially sorbitol and mannitol as film-formers and 3. 0.05 to 0.25 parts by weight of a humectant or defoamer, as well as possibly 4. an additive such as, for example, a resin. The core of the hot melt adhesive is preferably prepared by the known underwater granulation process, the outer layer being obtained by treatment with a refrigerant, which contains at least components 1 and 2 of the outer layer.
