    • A gypsum or foam facer is formed by the direct in-line or off-line coating of a preimpregnated, fibrous network matting with a secondary binder system. The pre-impregnated fibrous network is preferably formed of a randomly oriented wet use chop strand fiber material impregnated with a modified urea-formaldehyde binder system. The secondary binder system preferably consists of low glass transition acrylic or styrene- butadiene-rubber resin filled predominantly with fillers combined with a plate like reinforcement of fibrous reinforcement. In an alternative embodiment, a low basis secondary veil is layered onto the fibrous network matting with or without the secondary binder system to improve softness and decorative appearance of the formed gypsum board. In another preferred alternative embodiment, a plurality of high aspect ratio particles may be introduced to the binder prior to introduction of an optional secondary binder resin to also improve the softness and decorative appearance of gypsum board. ® KIPO & WIPO 2007
    • 石膏或泡沫面是通过直接在线或离线涂覆预先浸渍的纤维网络垫与二次粘合剂体系形成的。 预浸渍纤维网优选由浸渍有改性脲 - 甲醛粘合剂体系的随机取向的湿用剁丝纤维材料形成。 次级粘合剂体系优选由主要由填料组合的低玻璃化转变丙烯酸或苯乙烯 - 丁二烯 - 橡胶树脂组成,其中纤维增强物的增强材料如板。 在替代实施例中,将低基础二次面纱层叠到具有或不具有辅助粘结剂体系的纤维网状物上,以改善形成的石膏板的柔软度和装饰性外观。 在另一个优选的替代实施例中,在引入任选的次级粘合剂树脂之前,可以将多个高纵横比的颗粒引入到粘合剂中,以改善石膏板的柔软度和装饰性。 ®KIPO&WIPO 2007
