摘要： A sizing composition for reinforcement fibers that includes one or more film forming agents, a silane coupling agent package, and at least one lubricant surfactant is provided. Optional components such as rheology modifiers, fillers, biocides, and pH modifiers may also be included. Preferred film forming polymers are amide-based polymers. Additionally, the sizing composition is free of polyvinyl alcohol. The absence of polyvinyl alcohol in the size composition reduces or eliminates the production of precipitates from white water in wet-laid processes. The size composition is applied to reinforcement fibers and formed into chopped strand, wet-laid mats that can be used for a variety of purposes, including roofing products. Chopped strand mats formed from fibers sized with the inventive sizing composition maintains or improves the dry tear and tensile strengths compared to chopped strand mats made from fibers sized with a commercial sizing composition that does not contain polyvinyl alcohol.
摘要翻译：提供了包括一种或多种成膜剂，硅烷偶联剂包装和至少一种润滑剂表面活性剂的增强纤维用施胶组合物。还可以包括任选的组分如流变改性剂，填料，杀生物剂和pH调节剂。优选的成膜聚合物是基于酰胺的聚合物。另外，上浆组合物不含聚乙烯醇。尺寸组合物中不存在聚乙烯醇降低或消除了在湿法成网工艺中从白水生成沉淀物。尺寸组合物用于增强纤维并形成短切纤维，可用于各种目的的湿敷垫，包括屋顶产品。由使用本发明的施胶组合物尺寸的纤维形成的切断的丝网垫与由不含聚乙烯醇的商业施胶组合物尺寸的纤维制成的短切丝网垫相比，保持或改善了干撕裂和拉伸强度。

摘要： A roof covering includes a roofing mat formed from fibers of a fiber material. The fibers are coated with a sizing. The roof covering also includes a coating material that coats the mat. The coating material is based on an organic material. The sizing includes a sulfur-containing material that bonds to the fiber material. The sulfur-containing material has sulfur groups that form cross-links with the organic material. In another embodiment, the coating material contains sulfur added to the organic material. The sizing includes a bonding material that bonds to the fiber material and that bonds to the sulfur. The sulfur forms cross-links with the organic material.
