摘要： A composite structure including a polyurea show surface, or top layer, and a polyurethane backing layer is disclosed. Preferably, the show surface of the composite structure is substantially free of volatile organic compounds and is aliphatic such that it is ultraviolet light stable. Specifically, the show surface is the reaction product of an aliphatic polyisocyanate or aliphatic polyisocyanate blend, and of a resin component which is a polyamine. The resin component reacts with the aliphatic polyisocyanate to form a polyurea. The show surface has a Shore D hardness of 70. Like the show surface, the polyurethane backing layer of the composite structure is substantially free of volatile organic compounds. This backing layer is the reaction product of a second polyisocyanate component, such as polymeric diphenylmethane diisocyanate, and of a second-layer resin component, which comprises a polyol having a functionality of at least three. The complete composite structure has a flexural modulus of at least 200,000 lb/in2.

摘要： A method of making a polyurea—polyurethane composite structure that is substantially free from emission of volatile organic compounds is disclosed. The composite structure produced according to the method of the subject invention has a flexural modulus of at least 200,000 lb/in2. The composite structure includes first and second layers. A mold substrate is provided and a first-layer polyisocyanate component and a first-layer resin component are reacted and sprayed onto the mold substrate to form the first-layer. The first-layer polyisocyanate component includes an aliphatic polyisocyanate, and the first-layer resin component includes a polyamine thereby forming a polyurea show surface having a Shore D hardness of at least 65. After application of the first-layer, a second-layer polyisocyanate component and a second-layer resin component are reacted and sprayed behind the first-layer to form the second-layer of the composite structure. The second layer resin component more specifically includes a polyol having a theoretical functionality of at least three. The first and second layers of the composite are substantially free of VOCs.
摘要翻译：公开了制备基本上不含挥发性有机化合物的发射的聚脲 - 聚氨酯复合结构的方法。根据本发明的方法制备的复合结构的弯曲模量至少为20万磅/英寸2。复合结构包括第一和第二层。提供了模具基材，并将第一层多异氰酸酯组分和第一层树脂组分反应并喷涂到模制基材上以形成第一层。第一层多异氰酸酯组分包括脂族多异氰酸酯，并且第一层树脂组分包括多胺，从而形成肖氏D硬度至少为65的聚脲显示表面。施加第一层之后，将第二层多异氰酸酯组分和第二层树脂组分在第一层后面反应并喷涂以形成复合结构的第二层。第二层树脂组分更具体地包括具有至少三个理论官能度的多元醇。复合材料的第一层和第二层基本上不含VOC。
