A novel gypsum board having improved antifungal properties is disclosed. The board comprises a gypsum core, front and back paper facings, and a polymeric antifungal agent effective at inhibiting fungal growth. A preferred polymeric antifungal agent is polyDADMAC or polyTMMC. The novel gypsum board further comprises a non-polymeric antifungal agent comprising a fluorine-containing quaternary ammonium compound. Preferred non-polymeric ammonium compounds include Tetra-n-butylammonium fluoride and Tetraethylammonium fluoride. The polymeric antifungal agent can be present in the gypsum core and/or on one or both of the paper facings. The non-polymeric antifungal agent may be encapsulated in a material or ionically associated with the polymeric antifungal agent to allow releases of the non-polymeric antifungal agent over time and/or upon exposure to moisture. Methods for preparing the aforementioned novel gypsum board are also disclosed.
揭示了一种具有改进抗真菌性能的新型
石膏板。该板包括
石膏芯、正面和背面纸面以及一种聚合物抗真菌剂,有效地抑制真菌生长。首选的聚合物抗真菌剂是聚
DADMAC或聚TMMC。该新型
石膏板还包括一种非聚合物抗真菌剂,包括含
氟季
铵化合物。首选的非聚合物
铵化合物包括四正丁基
氟化铵和四乙基
氟化铵。聚合物抗真菌剂可以存在于
石膏芯中和/或在正面和/或背面纸面的一侧或两侧。非聚合物抗真菌剂可以封装在材料中或离子地与聚合物抗真菌剂结合,以允许随时间释放非聚合物抗真菌剂和/或在暴露于湿气时释放。还公开了制备上述新型
石膏板的方法。
